(Beyond Pesticides, May 3, 2017) Last week, researchers at the University of California San Diego revealed the first ever link between the use of neonicotinoid pesticides and the ability of bees to fly. Published in Scientific Reports, the study, “A common neonicotinoid pesticide, thiamethoxam, impairs honey bee flight ability,” builds on previous findings that neonicotinoid use interferes with bees’ ability to navigate, and concludes that exposure to thiamethoxam affects honey bee flight patterns as well as their physical ability to fly in ways that may be detrimental to their survival. The study is the latest in a growing body of science linking pesticide use to honey bee declines, raising concerns about overall honey bee health and longevity in the face of continued neonicotinoid use. According to the study, both acute and chronic exposure to thiamethoxam revealed significant alterations of the ability of bees to fly -affecting flight distances, duration of flights, and flight velocity. Researchers noted significant differences in bee behavior based on short versus long term exposure, which they summarized as having an “excitatory short-term effect and a depressive longer-term effect” on the bees’ ability to fly. This means that when bees were exposed to thiamethoxam for a short, […]

(Beyond Pesticides, April 5, 2017) A new study, Occurrence of Neonicotinoid Insecticides in Finished Drinking Water and Fate during Drinking Water Treatment, has detected neonicotinoids, a class of insecticides known for their detrimental effects on bees, in treated drinking water. This marks the first time that these insecticides have been found in water sourced straight from the tap. Federal regulators have not yet addressed safe levels of neonicotinoids in drinking water, so at this point, any detection of these chemicals is cause for concern. The study authors “report for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment.” Drinking water samples “collected along the University of Iowa treatment train” over a seven week period, May through July, 2016 directly after corn and soy planting, find three neonicotinoids, clothianidin, imidacloprid, and thiamethoxam at levels ranging from 0.24 to 57.3 ng/L (nanogams per liter). The University of Iowa tap water is run through a water treatment plant that uses conventional treatment methods.  In contrast, the Iowa City water treatment methods (granular activated carbon filtration) result in substantially lower levels of the neonicotinoids. Additionally, the researchers found that extensive transformation of clothianidin […]

(Beyond Pesticides, January 24, 2017) An analysis conducted by scientists at the University of St. Andrews in Scotland is calling into question the conclusions reached in a study conducted by multinational chemical company Syngenta, which indicated that honey bees were not at risk from the widely used neonicotinoid insecticide thiamethoxam. The challenge to the Pilling et al 2013 study is important because while many experiments have been performed in the lab or semi-lab environment, this study was a field experiment developed to test pollinator exposure under normal agricultural conditions. The conclusions of such real-world experiments are weighed more heavily by regulators when making safety and use determinations. St. Andrews’ scientists focus in on the Pilling et al claim that because its study did not have high levels of replication, that it would have been misleading to perform formal statistical analysis. They respond that this would indeed be the case if Pilling et al had intended on finding statistical significance and concluded that there was no effect based on those tests. However, Syngenta’s scientists instead simply graphed average values over time based on their measurements (measurements such as number of bees in a hive, hive weight, number of brood, etc.), and compared […]

(Beyond Pesticides, January 17, 2017) On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released major risk assessment documents on  pollinator exposure to bee-toxic neonicotinoid insecticides finding no significant risks, despite the large and growing body of science identifying the pesticides’ hazards. In the documents, EPA identifies risks posed to bees by several neonicotinoid insecticides, but suggests that no restriction on uses are imminent. In another decision meant to protect bees from acutely toxic pesticides, the agency is scaling back its original proposal in deference chemical-intensive agricultural interests. EPA’s long awaited pollinator assessments for the neonicotinoids: clothianidin, thiamethoxam, and dinotefuran, much like the 2016 pollinator assessment release for imidacloprid, identifies risks to bees from the agricultural applications (foliar, soil and seed) of these chemicals, including from pesticide drift. Observed effects include decline in worker bees, and subsequent declines in brood and pollen stores in the colony. EPA‘s assessments continue to focus on honey bees, with cursory mention of wild, native bees. Once again, the assessments did not consider risks from exposures to contaminated water, guttation droplets, or soil, with EPA stating that, “The Agency lacks information to understand the relative importance of these other routes of exposures and/or to quantify potential risks […]

(Beyond Pesticides, January 13, 2016) Just prior to the U.S. Environmental Protection Agency (EPA) announcement on January 12 that several neonicotinoid insecticides “do not pose significant risks to bee colonies,” the preprint version of a new review of neonics identified the range of lethal and sublethal effects of the chemicals on non-target organisms.  The review, The Environmental Risks of Neonicotinoid Pesticides: a review of the evidence post-2013, authored by Dave Goulson, PhD, and Thomas James Wood, a PhD candidate, concludes that studies published since the 2013 European Food Safety (EFSA) published risk assessments show even greater risks. The EFSA assessment, which led to a moratorium on neonicotinoid uses, found that certain neonics on specific flowering crops pose a high risk to bees. With reference to the 2013 EFSA risk assessment conclusions as their baseline, the researchers summarize the difference in risk for certain categories, including: “Risk of exposure from and uptake of neonicotinoids in non-crop plants. Uptake of neonicotinoids by non-target plants was considered likely to be negligible, though a data gap was identified. Many studies have since been published demonstrating extensive uptake of neonicotinoids and their presence in the pollen, nectar and foliage of wild plants. Exposure from non-target plants clearly represents a Greater […]

(Beyond Pesticides, December 8, 2016) On Monday, the Delaware Department of Agriculture (DDA) released its Managed Pollinator Protection Plan, which allows for the continuation of widespread pesticide use in landscapes across the state. The plan includes voluntary strategies for farmers, beekeepers, landowners and pesticide applicators, but fails to include any recommendations for reducing or eliminating toxic pesticide use. DDA resorts to recommending approaches that include “best management practices,” strategies to increase pollinator forage on public and private lands, and advocating for the use of Driftwatch, an online initiative that focuses on pesticide drift. Driftwatch is a voluntary effort run by the non-profit, Fieldwatch, which, according to its website, was created by Purdue University Agricultural and Biological Engineering and Agricultural Communications departments and  Purdue University Cooperative Extension Specialists  “to help pesticide applicators and specialty crop growers communicate more effectively to promote awareness and stewardship activities to help prevent and manage drift effects.” Like other state pollinator protection plans,  there is little mention of pesticides, despite the fact that neonicotinoids (neonics) are highly toxic, persistent and systemic pesticides that have been widely implicated as a leading factor in pollinator decline. According to environmentalists and beekeepers, little meaningful action has been taken to […]

(Beyond Pesticides, July 28, 2016)   Led by the Institute of Bee Health at the University of Bern, new research finds evidence that two commonly used neonicotinoid (neonic) insecticides have a significant adverse effect on the reproductive ability of male honey bees (drones) and queen bees in managed and wild colonies. The study,  Neonicotinoid insecticides can serve as inadvertent insect contraceptives, published in  Royal Society Journal Proceedings B, focuses on the differences in lifespan and viability of sperm throughout exposed and unexposed drones. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD).  Neonicotinoids, such as imidacloprid, thiamethoxam and clothianidin, have been found by  a growing body of scientific literature  to be linked to the CCD phenomenon and  pollinator decline in general. While science has become increasingly clear that these  pesticides  play a critical role in contributing to  the ongoing decline of bee health, this is one of the first to look at how these chemicals specifically effect the fertility of male honeybees. In the study, scientists randomly assigned honeybee colonies consisting of drones […]

(Beyond Pesticides, July 12, 2016) Canadian environmental organizations sued the  Canadian Pest Management Regulatory Agency (PRMA) last week in a bid to overturn the approval of two neonicotinoid pesticides linked to the decline of honey bees and wild pollinators. The move comes amid growing awareness, action, and scientific evidence linking this widely used class of insecticides to the global decline of pollinator populations. The lawsuit, filed  by Ecojustice on behalf of  The David Suzuki Foundation, Friends of the Earth Canada, Ontario Nature, and the Wilderness Committee, argues that pesticide products containing two neonicotinoids, clothianidin and thiamethoxam, are unlawfully registered in Canada. The groups allege that PMRA failed to ensure that it had the data necessary to determine the environmental risks, particularly those concerning pollinators, posed by the chemicals. “The PMRA has taken a see-no-evil, hear-no-evil, speak-no-evil approach by repeatedly registering these neonicotinoid pesticides without important scientific information on their risks to pollinators,” said Charles Hatt, staff lawyer at Ecojustice. Under Canada’s Pest Control Products Act, PMRA must have “reasonable certainty” that a pesticide will not cause harm to the environment before it is registered. The groups also note that several thiamethoxam-based products have been registered by the agency for years […]

(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

(Beyond Pesticides, March 16, 2016) Another study, this time from researchers at the University of Guelph, finds that at very low levels the neonicotinoid pesticide thiamethoxam affects  the foraging behavior of bumble bees, changing their floral preferences, hindering their ability to learn and extract nectar and pollen. This study is one of many that detail the negative effects of pesticides on bees’ learning behavior and ability to pollinate essential crops. Pesticides, like the neonicotinoid class of insecticides, have been implicated in the global decline of pollinator populations, while advocates call for  limiting pesticide exposures to reverse population declines. According to the authors of this Canadian study, “Chronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, “published in  the journal Functional Ecology, it is the first to explore how pesticides may impact the ability of bumble bees to  forage from common wildflowers that have complex shapes such as white clover and bird’s foot trefoil. The researchers found that bumble bees exposed to environmental levels of thiamethoxam (10ppb) took longer to collect pollen than unexposed bees, as well as foraged from different flowers. Importantly, this study reports that bumble bees that were not exposed to thiamethoxam are […]

(Beyond Pesticides, November 12, 2015) The U.S. Geological Survey (USGS) recently performed the first-ever study of pesticide residues on native bee populations and found that they are exposed to neonicotinoid insecticides, as well as other pesticides, at significant rates. This study digs deeper into a question  that was previously considered by a researcher who  studied chemical-intensive  apple orchards and linked a steep decline in wild or native bees to the application of pesticides. The USGS study  broadens understanding about the effects of toxic pesticides to native bee species, expanding field research that has principally focused on managed honey bee populations. The study tested for 122 different pesticides including bifenthrin, atrazine and chlorpyrifos, a chemical for which the U.S. Environmental Protection Agency (EPA) recently proposed to revoke all food tolerances in response to  a court-ordered deadline. According to study findings, 72% of bees tested positive for pesticide residues, raising concerns for the potential for unintended pesticides exposures where land uses overlap or are in proximity to one another.   Residues of pesticides found in bees in the study include  thiamethoxam, clothianidin, and imidacloprid, all of which are highly toxic neonicotinoids, a class of chemicals that have been linked to the global […]

(Beyond Pesticides, September 25, 2015) Neonicotinoid-treated seeds do not reduce crop damage from pests, adding to a growing body of evidence questioning the benefits of using these bee-toxic insecticides, according to a study  published in the journal BioOne. Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The study,  titled Impact of Western Bean Cutworm (Lepidoptera: Noctuidae) Infestation and Insecticide Treatments on Damage and Marketable Yield of Michigan Dry Beans, examines the relationship between western bean cutworm infestation and damage in dry beans, and the use of seeds treated with the neonicotinoid thiamethoxam, as well as soil treated with aldicarb, another systemic insecticide. Researchers have concluded that neither thiamethoxam nor aldicarb reduced cutworm damage. In fact, plots treated with these insecticides had a higher percentage of defects due to feeding by pests when compared to untreated plots, which researchers believed is  attributable to factors such as fewer natural enemies. There have been additional reports and studies published over the past few years questioning the benefits of neonic use. In […]

(Beyond Pesticides, August 28, 2015) The European Union’s food safety agency confirmed Wednesday that foliar spraying of neonicotinoids (neonics), the widely-used bee-toxic insecticides, poses a risk to bees, bolstering previous research that led to a two-year moratorium on the chemicals in the EU. The European Food Safety Authority (EFSA), which guides EU policymakers, said leaf spray containing three neonicotinoid pesticides — clothianidin, imidacloprid, and thiamethoxam — could harm bees. Previous research found that these chemicals pose a risk as seed treatments or granules, which prompted the European Commission to limit their use in  December 1, 2013. The use of the three neonicotinoid substances in seed or soil treatments is prohibited in the European Union for crops attractive to bees and for cereals other than winter cereals except in greenhouses. “They (the EFSA conclusions) confirm that the Commission was correct to take precautionary measures in 2013,” a Brussels-based EU executive said in a statement. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and pollinator decline. Recently, a  study  performed by the Food and Environment Research Agency (FERA) in the United Kingdom provides evidence confirming the link between neonicotinoid pesticides and continually increasing […]

(Beyond Pesticides, July 24, 2015) An emergency application was approved by the UK Department for Environment, Food, and Rural Affairs (DEFRA) on Wednesday that allows  farmers to use neonicotinoid seed treatment on 5 percent of oilseed rape crop (known as canola in the U.S.) this summer to control a flea beetle infestation. The emergency use, which has been granted for 120 days, allows growers to use Bayer CropScience’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals knowns as neonicotinoids, which have been linked to pollinator decline. The request was the second one for the National Farmers Union (NFU) after the first request for a nationwide lifting of the two-year moratorium on neonicotinoid use was rejected. The NFU said it was “frustrated” at having to put in an application for a smaller area. There have been numerous attempts to shroud the application process in secrecy. DEFRA told its expert committee on pesticides (ECP) to halt its  normal practice of publishing the minutes  of meetings at which the neonicotinoid applications were discussed, in order to avoid “provoking representations from different interest groups.” Additionally, according to the Guardian, the UK government […]

(Beyond Pesticides, July 23, 2015) A recent study looks at the detrimental effects of neonicotinoids (neonics) on molluscan herbivores and their non-target insect predators, finding that slug exposure to neonics results in the secondary poisoning of beneficial predatory beetles. The study, authored by Maggie Douglas, PhD candidate at Penn State University, was presented earlier this month at a congressional briefing, An Expert Briefing to Discuss Pollinators and Efforts to Protect Them. The briefing was organized by Center for Food Safety and attended by the sponsors of Saving America’s Pollinators Act (H.R. 2692), Representatives John Conyers (D-MI) and Earl Blumenauer (D-OR). The study specifically looks at the pest slug Deroceras reticulatum and its predator beetle, Chlaenius tricolor. Ms. Douglas and her co-researchers find that neonicotinoid seed-treated soy beans can unintentionally impact predatory, beneficial insects through a previously unexplored pathway. Here are some highlights of the study’s methods and findings: Soy beans were treated with the neonicotinoid thiamethoxam. The seed treatments had zero effect on pest slugs, and instead were bioaccumulated and then transferred through the slugs into their insect predators, impairing or killing >60%. This resulted in a loss of crop due to a decline in beneficial insect predators and an […]

(Beyond Pesticides, March 27, 2015) Portland, Oregon is considering a ban on neonicotinoids, a class of insecticides linked to bee deaths, from use on city property. If the measure passes, Portland will join a long list of towns and communities, including Eugene (Oregon),  Skagway (Alaska),  and, in Washington State, Thurston County,  Seattle, and Spokane. Under the proposed ordinance, city officials would not be permitted to use or buy neonicotinoids or similar pesticides on city lands or in city buildings and would urge stores to label products, such as plants and seeds treated with neonicotinoids. The proposal also applies to city contractors. Additionally, the proposed ban on neonicotinoids and neonicotinoid-like insecticides would not apply immediately to two city rose gardens. Officials say the rose midge, a pest, is difficult to eradicate with the insecticide. Instead the city will look for an alternative method using a pilot project at Peninsula Park in North Portland to test alternative non-toxic insecticides. That proposal would be phased in with a deadline of December 2017 to eliminate all neonicotinoid-based products. The proposal cites seven separate bumble bee incidents in Oregon related to the application of neonicotinoids on trees since June 2013, documented by the state’s Department […]

(Beyond Pesticides, March 6, 2015) Last Friday, Oregon enacted a new rule which bans the use of four types of bee-killing insecticides, including  imidacloprid, clothianidin, thiamethoxam and dinotefuran, regardless of application method on linden trees and other Tilia species. The four insecticides that are now illegal to spray on Tilia trees are all in the neonicotinoid chemical class which are implicated in pollinator decline, and represents a step forward in protecting bees. However, Tilia trees are not the only route of exposure that bees and other pollinators have to neonics, which are currently applied to fields across the U.S. as seed treatment. The rule comes at the request of the Oregon Department of Agriculture (ODA) following several bee-kill incidents in Oregon since June 2013, when more than 50,000 bumblebees were killed after dinotefuran was sprayed on trees in a shopping mall parking lot in Wilsonville, Oregon. After the incident in Wilsonville, ODA initially placed restrictions on two of the chemicals, dinotefuran and imidacloprid on Tilia trees, and the state launched a task force to look at protections for pollinators. The group came out with a range of recommendations including increased outreach and education about bees and support for bee habitat […]

(Beyond Pesticides, January 14, 2015)””More than 100 businesses, including Clif Bar, Nature’s Path, Organic Valley and Stonyfield, sent a letter to the White House yesterday urging it to immediately suspend pesticides linked to global bee declines in order to protect the nation’s food supply, environment and economy. The businesses, members of the American Sustainable Business Council (ASBC) and Green America’s Green Business Network, voiced concerns about the U.S. Environmental Protection Agency (EPA)’s delays in restricting neonicotinoids, the world’s most widely-used insecticides. Many of the 118 businesses that signed the letter sell products with ingredients or inputs that are dependent on pollination from bees and other pollinators, including fruits, vegetables, nuts, seeds, fiber (such as cotton) and hay (including alfalfa grown to feed livestock). The businesses call on the EPA to immediately suspend the registrations of neonicotinoids for agricultural uses, including seed treatments, as well as cosmetic and other unnecessary uses pending the results of pesticide re-evaluation. They also called for increased investments in green, fair and cutting-edge alternatives to neonicotinoids that support a prosperous and sustainable agricultural system. “We are very concerned about the continued and unsustainable losses of bees and other essential pollinators and what effects this will have […]

(Beyond Pesticides, November 26, 2014) Last week, over 100 scientists from diverse disciplines released a letter citing the growing body of scientific evidence that neonicotinoids and other systemic pesticides harm bees, and called on leaders of President Barack Obama’s Pollinator Health Task Force to quickly take action on pesticides to protect and promote healthy populations of bees and other pollinators. The letter was submitted in response to the recent “listening sessions” hosted by U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA). These sessions were held by the agencies to  collect public  feedback  on federal efforts on pollinator protection, and the Task Force convened to develop a National Pollinator Health Strategy. In June, the White House issued a Presidential Memorandum directing federal agencies to  join the  Pollinator Health Task Force, led by USDA, to develop pollinator health solutions. The 108 scientists ””whose areas of expertise include entomology, agronomy, ecology, ecotoxicology”” called on Task Force co-chairs, EPA Administrator Gina McCarthy, and USDA Secretary Tom Vilsack, to place a moratorium on the use of neonicotinoid pesticides in the U.S., and increase investment, research and funding for growers to adopt alternatives. In the letter, the scientists note that, “While gaps […]

(Beyond Pesticides, November 5, 2014) New research from Pennsylvania State University reports that pesticides cause large changes in the expression of genes involved in detoxification, immunity and nutrition-sensing in bees, adding to previous research that has found that pesticides compromise bee immune function. This research also finds that bees with a diet of natural, high quality pollen exhibit greater resistance to pesticides’ deleterious effects than bees on an artificial diet. The new study, “Genomic analysis of the interaction between pesticide exposure and nutrition in honey bees (Apis mellifera),” finds that pesticide exposure can impact the expression of genes that are sensitive to diet and nutrition. The researchers, upon feeding honey bees either the miticidal pesticides, coumaphos or fluvalinate, for a period of seven days, noticed significant changes in 1,118 transcripts – or strands of RNA – in the experimental group. The transcripts include genes involved in detoxification, immunity, and nutrition. The authors report that there is substantial overlap in responses to pesticides and pollen-containing diets at the genetic level. Subsequent analyses demonstrate that pollen-based diets reduce the honey bees’ susceptibility to pesticide stress verses an artificial diet – e.g. a soy protein or no protein diet. Thus, the researchers note […]

(Beyond Pesticides, October 31, 2014) Without any mention of the role of pesticides in bee decline, or emphasis on organic practices to help pollinators, Agriculture Secretary Tom Vilsack announced Wednesday that more than $4 million in technical and financial assistance will be provided to help farmers and ranchers in the Midwest improve the health of honey bees. The announcement renews and expands on a $3 million pilot investment last spring to create pollinator-friendly habitat in five Midwestern states. The effort responds to the Presidential Memorandum, which directs USDA to expand the acreage and forage value in its conservation programs. The Memorandum, issued at the close of National Pollinator Week 2014, directed federal agencies to establish a Pollinator Health Task Force, and tasked agency leads at the U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) to develop a pollinator health strategy within 180 days that supports and fosters pollinator habitat. “The future of America’s food supply depends on honey bees, and this effort is one way USDA is helping improve the health of honey bee populations,” Vilsack said. “Significant progress has been made in understanding the factors that are associated with Colony Collapse Disorder and the overall health […]

(Beyond Pesticides, October 20, 2014) The U.S. Environmental Protection Agency released a report Thursday that soybean  seed treatments with neonicotinoid insecticides provide little or no overall benefits in controlling insects or improving yield or quality in soybean production. While pesticide manufacturer Syngenta has petitioned EPA to raise the allowable levels of another systemic pesticide thiamethoxam on a number of crops, EPA’s report confirms  scientific findings  that these chemical treatments are unnecessary and inefficacious. Widely used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The report concludes that not only is there no increase in soybean yield when compared to using no pest control at all, but also the potential benefit of neonicotinoid seed treatment is not likely to be large or widespread throughout the U. S. EPA also found that seed treatments fail to provide protection from target pests during critical times of plant activity, ultimately leading to the assessment that “much of the existing usage on soybeans is prophylactic in nature.” “This report demonstrates, yet again, the need for […]

(Beyond Pesticides, September 10, 2014) As bee and other pollinator populations continue to decline around the world, with clear evidence pointing to neonicotinoid pesticides as a prime cause, Emory University announced last week that it will be eliminating the use of this controversial class of chemicals from its campus, joining institutions and  communities like University of Vermont Law School, Spokane  (Washington),  Eugene (Oregon), and Shorewood (Minnesota). Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects,  affecting the organisms’ ability to function. These systemic pesticides, which move through the plant’s vascular system and express themselves through pollen and nectar, include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. A continually growing body of science has implicated neonicotinoids, which are applied to or incorporated into seeds for agricultural, ornamental and garden plants, as a key factor in recent global bee die-offs. Beekeepers across the country reported losses of 40 to 90 percent of their bees last winter. The implications of this loss are staggering —one in every three bites of food is reliant on bee pollination, and pollinators make possible  $20-30 billion of annual U.S. agricultural production. Last week, Emory […]
