Established in 1993, Some Insect Management Some Entomological Research (SIMSER) provides a range of arthropod-related services including scouting and monitoring, pest suppression with nontoxic materials and contract research. The owner and sole employee, Dave Simser, is a board-certified entomologist and licensed pesticide applicator in Massachusetts. Services include pest management in greenhouses, development of 'organic' pest management in cranberries, coordinator of deer tick surveillance and suppression, and field testing of products.

What is your definition of Integrated Pest Management (IPM)?

I believe the IPM acronym is somewhat outdated. Growers and other practitioners must think in terms of the more refined Plant Health Care. I prefer to relate to the definition by Lloyd and Miller of PHC as 'a comprehensive program with a focus on the plant and the client.' My personal goal and philosophy is to apply and release the least toxic materials and organisms available commercially against the specific pest, as appropriate. I am not liberal with any applications, often instructing the client that 'this or that pest is 1) really not a pest, or 2) the numbers of this species do not require suppression.' At other times, pest population requires treatment and such is performed, with an appropriate response.


Is pest management performed on a specific schedule?

Insect management schedules dependent entirely upon the individual situation.

How are pest problems identified?

Pest problems are identified by experience or reference material (including the appropriate experts).

What practices do you use to prevent and/or control pests?

If it works, syringing (hosing) of sessile pests such as aphids and spider mites, followed by release of appropriate beneficials, or application of a 'natural' product, or perhaps a product certified as organic by Organic Materials Review

Do you use biological controls?

Yes, whatever is available for a pest problem. BotaniGuard (fungus) as an ESS (electrostatic sprayer).

Do you use borates?

Did Not Respond (DNR)

Do you use synthetic chemicals?

Yes, but very limited and primarily against the major greenhouse pest, western flower thrips in June/July. Marathon (imidacloprid) in early season. We also use Remedy (potassium carbonide), Azatin products and Safer Soap (pyrethrum).


What are the top 10 pesticides you use/sell/recommend?

Beneficials first, and: 1) Ultra-Fine Spray oil 2) Botanigard (fungus) 3) Remedy 4) Azatin products and 5) Safers Soap.

If pesticides are used, how much are used per year of each?

Less than a quart of the active ingredient of each product listed above, and with appropriate and well maintained equipment.

Does your company perform habitat modification?

I always move greenhouse plants so they are sitting under the correct light, we use the ecoisland technique or using plants in bloom to provide nector (always watered prior to the release of the insects) for beneficials in the field.


Do you use any physical or mechanical controls?

Yes, the afore-mentioned water spray, simple picking or shaking pests off and the occasional row cover.

What type of fertilizers do you use/sell/recommend?


What do you usually use/sell/recommend for addressing:

termites DNR

cockroaches DNR

fleas DNR

carpenter ants DNR

fire ants DNR

ants (indoor) DNR

crabgrass DNR

dandelions DNR
