Decrease Found in Retail Sales of Plants Treated with Bee-Toxic Pesticides

Wednesday, August 17th, 2016

(Beyond Pesticides, August 17, 2016) In response to dramatic scientific findings, a severe decline in bee populations, and growing public demand for bee-safe plants, a new report confirms  the decision  of  major retailers to phase-out  the sale of flowers and trees treated with the pesticides most closely associated with the decline —neonicotinoids. A new report released by Friends of the Earth, analyzes plants purchased at  Home Depot,  Lowe’s, Ace Hardware,  True Value  and  Walmart. Many of these major retailers have made public commitments to stop selling bee-toxic neonicotinoids and treated plants. Additionally, the states of Maryland and Connecticut have passed legislation that stops the retail sales of neonics. The report,  Gardeners Beware 2016, released yesterday is a follow-up to previous testing that demonstrated the presence of bee-toxic neonicotinoid insecticides in more than half of bee-attractive flowers tested. The 2016 analysis found that 23 percent of flowers and trees tested contain neonicotinoid insecticides at levels that can harm or kill bees, compared to 51 percent in 2014, indicating that stores are selling far fewer plants treated with bee-killing neonics. This reduction is likely due to changes in store policies that commit retailers to eliminate neonicotinoid use on garden plants. Retailer commitments […]

Pesticides Registered by EPA Alter Honey Bee Microbiome

Friday, August 12th, 2016

(Beyond Pesticides, August 12, 2016) A new study by a team of scientists at Virginia Tech finds that commonly used in-hive pesticides result in changes to the honey bee gut microbiome. The study, Honey bee gut microbiome is altered by in-hive pesticide exposures, was led by Virginia Tech associate professor of horticulture, Mark Williams, Ph.D., and colleagues from Oregon State University and North Carolina State University. This research, published several weeks ago in the journal Frontiers in Microbiology, aimed to determine the microbiome of honey bees (Apis mellifera) after being exposed to three common pesticides. Coumaphos and tau-fluvalinate, both common miticides used in conventional beekeeping, and chlorothalonil, a fungicide commonly detected in hives, were used as pesticide treatments in the study. While this  research contributes to the already established body of science on the complexity of pesticide exposure effects, beekeepers reported the steepest, and then sustained, declines in honey bee populations after the large  increase in  neonicotinoid pesticide  use in the early 2000’s. Beekeepers nationwide suffered  their highest hive losses of 44.1% in the last national survey from April 2015-2016. While it is likely that neonicotinoids are not the sole factor in pollinator decline, they have been found to exacerbate […]

Study Adds to Findings that Link Prenatal Pesticide Exposure to Lower IQs

Friday, July 29th, 2016

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

Neonicotinoid Insecticides Affect Bee Reproduction

Thursday, July 28th, 2016

(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 […]

Mixtures of Multiple Pesticide Ingredients in Products Not Evaluated by EPA for Elevated Toxicity

Thursday, July 21st, 2016

(Beyond Pesticides, July 21, 2016) An investigative report released yesterday by Center for Biological Diversity (CBD) concludes  that, over the past six years, the U.S. Environmental Protection Agency (EPA) has approved nearly 100 pesticide products with chemical mixtures that elevate the formulations’  toxicity, but are not specifically evaluated  by the agency. CBD finds that these formulations add  more stress to already-jeopardized pollinators and rare plants. The report Toxic Concoctions: How the EPA Ignores the Dangers of Pesticide Cocktails, highlights a long-running blind spot within EPA’s pesticide evaluation program, which Beyond Pesticides has long sounded the alarm on: the risk associated with combining mixtures of different pesticide active ingredients, which independent science shows may be more toxic than a single active ingredient by itself, also known as pesticide synergism. The mixtures occur as a result of multiple ingredients in individual products or  because of exposure to multiple pesticide product residues in food, air, water, and land areas, such as lawns, playing fields, and parks. “It’s alarming to see just how common it’s been for the EPA to ignore how these chemical mixtures might endanger the health of our environment,” said Nathan Donley, Ph.D., a scientist with the CBD, and author of […]

Designated Pollinator Habitat Areas Still Put Pollinators At Risk

Wednesday, July 20th, 2016

(Beyond Pesticides, July 20, 2016) Farmers and land managers across the U.S. are being encouraged to plant pollinator habitat adjacent to farmlands to provide shelter and food for pollinator species. But according to a new study published last week, these conservation areas still put bees at risk for pesticide contamination, as they fail to provide spatial or temporal relief. This study emphasizes that meaningful solutions to reversing pollinator decline does not lie with focusing on planting pollinator habitat, but ensuring that these refuge areas are free from pesticide contamination, highly toxic to bees and other pollinators, and reducing the reliance on toxic chemical inputs in agriculture and other landscapes. The study, “Neonicotinoid-contaminated pollinator strips adjacent to cropland reduce honey bee nutritional status,” finds that pollinator habitat adjacent to agricultural areas not only becomes a source for pesticide, especially neonicotinoid, exposures, but also poses significant risk to honey bees. The authors, Christina Mogren, PhD, and former USDA entomologist, Jonathan Lundgren, PhD, initially sought to study whether increasing forage by planting pollinator habitat in an agricultural-dominated region would serve to buffer against the harmful effects of plant-incorporated pesticides. However, the authors note that it soon became apparent that the unintended consequence was […]

Canadian Environmental Groups Sue to Stop Bee-Toxic Pesticide Use

Tuesday, July 12th, 2016

(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 […]

Malibu, CA City Council Unanimously Votes to Ban Pesticides on Public Property

Tuesday, July 5th, 2016

(Beyond Pesticides, July 5, 2016) Last week, Malibu City Councilmembers, in a unanimous decision (5-0), voted to make Malibu, California’s (CA) public spaces poison free, which means an immediate ban on all pesticides, rodenticides and herbicides. During a marathon meeting that ran into the early hours past midnight, more than 24 Malibu residents and stakeholders came to give public comments on pesticide use on public parks and city property. You can view the city council meeting here. The entire discussion and vote is included, starting at 3:29:37 (or section 6.A.). Many of the residents were with an community  group called Poison Free Malibu, which is a group that advocates for the elimination of toxic pesticide use in the area. According to the Malibu Times, Kian Schulman, RN, founder of Poison Free Malibu, gave a presentation on the effects of pesticide chemicals and their connection to diseases such as cancer and neurological issues like ADHD and Alzheimer’s. Ms. Schulman’s presentation included a picture of a city worker spraying pesticides on Legacy Park, while wearing a full hazmat suit as a child rode their bicycle close by. Several Poison Free Malibu supporters attended the meeting and gave a presentation on the adverse […]

France on Track to Ban All Neonicotinoid Pesticides by 2018

Friday, July 1st, 2016

(Beyond Pesticides July 1, 2016) Lawmakers in France approved plans to totally ban neonicotinoid pesticides by 2018, based on their link  to declining populations of pollinators, specifically bees. This new restriction would go above and beyond current European Union (EU) restrictions on neonicotinoids, which limit the use of neonicotinoids, but do not ban them. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the  country’s  National Assembly, as part of a bill on biodiversity. While the bill must still gain the approval of the French Senate, which rejected it in a previous reading, passage by the Assembly is significant, as France becomes the first country to join state and local movements to eliminate the use of these toxic chemicals. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and other pollinator declines. In light of these findings, in 2013 the European Commission  voted to suspend  the use of neonicotinoid pesticides for two years. The ban came several months after the European Food Safety Authority (EFSA)  released a report  identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals.   Along with recent reports […]

Howard County, MD, Plans to Ban Neonics on Parklands

Thursday, June 30th, 2016

(Beyond Pesticides, June 30, 2016) In a move that goes one step further than the recently passed state-wide bill restricting consumer sales of neonicotinoid (neonics) products, Howard County, Maryland has taken the initiative to restrict the use of neonicotinoids on parklands. The new policy, announced June 16, cites the growing number of studies linking neonicotinoid use to adverse effects on pollinator species. The Department of Recreation and  Parks (DRP) manages approximately 10,000 acres of parkland within Howard County. According to the new policy and procedure, DRP is restricting the use of neonicotinoids, “due to recent research suggesting that there is a link between pesticides that contain neonicotinoids negatively effecting populations of pollinator species, such as; honeybees, native bees, butterflies, moths and other insects.” Neonics were often used on parklands for grubs on turf, Japanese beetles on trees,  and aphids on flowers and are now prohibited on all County parkland, including sports fields, garden plots, golf course and open space. Exemptions exist for agricultural uses and invasive pest infestations. Read the new neonicotinoid policy. Just this past May, Maryland officially became the first state in the nation to pass legislation  against neonicotinoids. The state legislature passed the  Maryland Pollinator Protection Act […]

Millions of Dead Bees and Over 4 Million Signatures Presented to EPA to Protect Pollinators from Pesticides

Thursday, June 23rd, 2016

(Beyond Pesticides, June 23, 2016) A truck full of dead bees made its final stop yesterday at a rally outside the headquarters of the U.S. Environmental Protection Agency (EPA), culminating a coast-to-coast tour to raise awareness about recent massive declines in pollinators. While the millions of dead bees stayed on the truck, advocates and beekeepers, including Beyond Pesticides, delivered over 4 million signatures urging an immediate ban on bee-killing pesticides. “In the five years since I started keeping bees, I’ve seen many hives killed by pesticides,” said James Cook, a Minnesota-based beekeeper who has been driving the truck across the country since last Monday. “If some fundamental things don’t change, it’s going to be really hard for beekeepers to adapt to the environment around us.” Bees pollinate most of the world’s most common crops, including summer favorites like peaches and watermelon. But over 40 percent of U.S. honeybee hives die each year, costing the farming and beekeeping industry more than $2 billion annually. The most significant culprit in the bee die-off is the widely-used class of pesticides called neonicotinoids, or neonics. Last spring EPA began a process to assess four types of neonics and their impacts on pollinators. In January […]

Students Celebrate Pollinators by Spreading Bee and Butterfly Habitat

Monday, June 20th, 2016

(Beyond Pesticides June 20, 2016) As the end of the school year approaches, two first grade classrooms at local District of Columbia Public Schools (DCPS) got to learn about the importance of pollinators firsthand when DC-based nonprofit Beyond Pesticides visited their school. In a lead up to National Pollinator Week, Beyond Pesticides teamed up with owner and founder of The Bees Waggle, Jessica Goldstrohm, to provide a fun, hands-on lesson about pollination, and why it is important to our food system. Students were given a lesson on biodiversity, soil health, and the negative effects of pesticides on pollinators before building some pollinator-friendly habitat for their schools and homes. The day of learning kicked off at Brightwood Education Campus, located in Northwest DC, where students listened to a lesson developed by Ms. Goldstrohm, who donned a set of bee wings for the event. After receiving some background on the role of pollinators in our food system, the children participated in several hands on activities that reiterated the key points within the curriculum. Six volunteers stepped to the front of the class to demonstrate the interconnectedness of all living organisms by participating in a biodiversity web simulation. Here, the scholars learned that […]

Report Details Industry Efforts to Derail Pollinator Protections

Friday, June 17th, 2016

(Beyond Pesticides, June 17, 2016) The pesticide industry has weakened and delayed pesticide reforms and is shaping new state pollinator “protection” plans nationwide that do little to protect bees, according to a new Friends of the Earth report.  The report is being released in advance of  Pollinator Week (June 20-26, 2016), as people assemble to ask for improved protection for pollinators. The investigation, Buzz Kill: How the Pesticide Industry is Clipping the Wings of Bee Protection Efforts Across the U.S., reveals an array of pesticide industry tactics to slow urgently needed pollinator protection measures at federal and state levels. The report details how new state pollinator protection plans, many still unfinished, have been heavily influenced by pesticide industry interests. According to the report, industry is spending hundreds of thousands of dollars on lobbying to delay state and federal action on the chemicals they manufacture. As a result, state pollinator protection plans across the U.S. are falling short in several ways, including: State pollinator protection plans currently provide more protections for pesticides and pesticide users than for bee keepers and bee colonies. Pesticide industry influence is pervasive throughout states’ legislative and regulatory planning efforts. Plans lack metrics to measure effectiveness, improvement […]

Local Restaurants Launch Campaign to Protect Pollinators during National Pollinator Week

Tuesday, June 14th, 2016

(Beyond Pesticides, June 14, 2016) To celebrate National Pollinator Week, June 20-26, 2016, several Washington, DC restaurants have teamed up with Beyond Pesticides and the Center for Food Safety to launch a campaign, “Made by Pollinators,” to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurants’ patrons will be treated to a special menu featuring pollinator-friendly food and provided with information on what they can do to help pollinators. The restaurants hope to increase public awareness on the importance of pollinators and steps that can be taken to reverse the decline. Participating  restaurants include Busboys and Poets, Founding Farmers, Lavagna, the Tabard Inn and Restaurant Nora. Of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. The value of pollination services to U.S. agriculture alone amounts to nearly $30 billion and about 80% of flowering plants require animal pollination. A recent government survey reports that U.S. beekeepers lost 44 percent of their colonies between spring 2015 and 2016 —the second highest loss to date. […]

Public Comment Needed on EPA’s Plans To Allow Bee-Toxic Sulfoxaflor despite Elevated Bee Losses

Friday, June 3rd, 2016

(Beyond Pesticides, June 3, 2016) Despite recent reports of continuing bee losses across the U.S., the U.S. Environmental Protection Agency (EPA) has announced plans to reevaluate the use of the bee-toxic insecticide sulfoxaflor, and is proposing an amended registration. Sulfoxaflor’s initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and EPA’s inadequate review of the data. Last September, the  Ninth Circuit Court of Appeals unequivocally rejected  EPA’s registration of sulfoxaflor. The Court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may  have on honey bee colonies. The Court vacated EPA’s unconditional registration of the chemical, meaning that sulfoxaflor could no longer be used in the U.S. This decision was in response to a suit filed by beekeepers challenging EPA’s initial registration of sulfoxaflor, which cited the insecticide’s threat to bees and beekeeping. The case:  Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, American Beekeeping Federation, Thomas Smith, Bret Adee, Jeff Anderson v. U.S. EPA  (9th Circuit U.S. Court of Appeals,”¯No. 13-7234) According to the court decision, EPA skirted its own regulations […]

Study Finds Honey Bees Frequently Collect Contaminated Pollen from Non-Crop Plants

Wednesday, June 1st, 2016

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

Maryland Pollinator Protection Act Becomes Law

Friday, May 27th, 2016

(Beyond Pesticides, May 27, 2016) — Thanks to the hard work and efforts of beekeepers, environmental groups, scientists, legislators and activists, Maryland is the first state to pass legislation through its General Assembly that restricts consumers from using neonicotinoids, a pollinator-toxic pesticide. Earlier this month, the state of Connecticut also passed far-reaching legislation aimed at protecting pollinator populations from these toxic chemicals. The Maryland Pollinator Protection Act (Senate Bill 198/House Bill 211) will become law without the Governor’s signature. Supporters had feared a veto from the executive office, but as a result of overwhelming pressure from beekeepers and activists, Governor Larry Hogan (R) allowed the bill to come into law. Under the Act, consumers will not be permitted to buy pesticides that contain neonicotinoids starting in 2018. Certified pesticide applicators, farmers and veterinarians will be still be allowed to use neonicotinoids. Connecticut’s bill also restricts consumer use of neonicotinoids. In addition, it requires the creation of pollinator habitat on state lands, and begins to address the use of these chemicals in agriculture by developing best practices on neonicotinoid coated seeds, and model pollinator habitat in farm preservation programs. As Maryland’s bill made its way through the legislature, an amendment was […]

Maryland Residents Asked to Urge Governor to Sign Pollinator Protection Act, Under Threat of Veto this Week

Thursday, May 26th, 2016

(Beyond Pesticides, May 26, 2015) Maryland’s historic Pollinator Protection Act, (SB 198 and HB 211) may be in danger. Last month, lawmakers approved the bill by a 98-39 vote in the Maryland House of Delegates, however it faces the possibility of a veto by Governor Larry Hogan (R). While the governor’s office says that the bill is currently under review, according to local news source WBAL, the governor is prepared to veto the bill, which he has until tomorrow, Friday, May 27, to do. If the governor does veto the bill, Maryland’s Pollinator Protection Act will go back to the legislature for an override vote, which will take place in early 2017. Meanwhile, beekeepers continue to lose their bees at unprecedented rates. Last week, we reported results of 2015-16 Colony Loss Survey, which show no sign that the crisis of abating. According to the survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. WBAL reports that the governor is likely to veto the bill because of […]

A Decade into the Pollinator Crisis, Unsustainable Bee Losses Continue

Tuesday, May 17th, 2016

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ”” and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

Macalester College Signs Resolution to ‘Bee Protective”

Thursday, May 12th, 2016

(Beyond Pesticides, May 11, 2016) Another campus, Macalester College in St. Paul, Minnesota has pledged to become a designated BEE Protective campus. This recognition comes from Beyond Pesticides’ and Center for Food Safety’s BEE Protective Campaign, which aims to protect bees and other pollinators from harmful pesticides like neonicotinoids. As part of its  commitment, Macalester College will  no longer use neonicotinoids on its  campus grounds. Neonicotinoids are a class of pesticides known to have severe impacts on bee populations. Macalester is now one of several campuses around the country that have pledged to protect pollinators and move away from using harmful pesticides that are toxic to these beneficial creatures. Just last month,  Antioch College in Yellow Springs, Ohio pledged to become a BEE Protective campus. In addition to these campuses, several local communities and states are also taking a stand for pollinators by passing policies that restrict the use of bee-toxic pesticides. For more on how your campus or student group can support pollinators and become BEE Protective, visit the BEE Protective Ambassadors webpage. “Macalester’s new resolution to help protect pollinators fits well with our Sustainability Plan and Sustainable Landscaping Master Plan.

Connecticut Legislature Votes Unanimously to Adopt Pollinator Protections

Tuesday, May 3rd, 2016

(Beyond Pesticides, May 3, 2016) In a bipartisan victory for bees, last week the Connecticut House of Representatives unanimously (147-0) passed a wide-ranging bill aimed at protecting declining pollinator populations within the state from toxic neonicotinoid (neonic) pesticides. Bill No. 231, An Act Concerning Pollinator Health, was also passed unanimously (36-0) through the Connecticut State Senate on April 21, and now goes to Governor Dannel P Malloy for his signature. Earlier in April, both houses of the Maryland legislature passed the Maryland Pollinator Protection Act, which is currently awaiting action by Governor Larry Hogan (R). Connecticut’s bill addresses a broad range of concerns relating to pollinator health, from pesticides to parasites and habitat remediation, within both residential and agricultural settings. In summary, the bill does the following: Prohibits applying neonicotinoid insecticide (a) to linden or basswood trees or (b) labeled for treating plants, to any plants when such plant bears   blossoms; Bee health experts identified the application of systemic neonicotinoids to Tilia trees as a significant concern for pollinator health after a spate of massive bee-kill incidents on the west coast. In June 2013, over 50,000 bumblebees were killed after a neonic was applied to a linden trees in […]

Study Finds Neonicotinoids Cause Compound-Specific Harm to Bumblebees

Monday, May 2nd, 2016

(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 […]
