ACE Grooming Techniques 4

Question 1

Which formulation type of insecticide is most enhanced in efficacy by cockroach autogrooming behavior?

Accepted Answer

Dusts and desiccant powders

Answer

Dust and desiccant formulations adhere to cockroach cuticle and appendages and are ingested during grooming, providing dual contact and oral exposure.

Question 2

Isopropyl alcohol is sometimes used in laboratory entomology to clean insects. What is the primary reason for cleaning specimens before pinning?

Accepted Answer

To remove oils and debris that attract dermestid beetles

Answer

Residual oils and organic debris on pinned specimens attract museum pests like dermestid beetles that damage collections.

Question 3

Which genus of parasitic mites on honey bees is controlled in part by selecting for enhanced grooming behavior in bee colonies?

Accepted Answer

Varroa

Answer

Varroa destructor is the primary target of grooming-based resistance breeding programs in honey bees.

Question 4

In Integrated Pest Management (IPM), understanding that insects groom after walking across boric acid deposits is most relevant to treatments targeting which pest?

Accepted Answer

All of the above equally

Answer

All cockroach species engage in autogrooming, making boric acid dust effective against any cockroach species that contacts treated surfaces.

Question 5

What is the primary behavioral reason that slow-acting (delayed) toxicants are preferred over fast-acting ones in social insect bait programs?

Accepted Answer

Workers survive long enough to return to the colony and transfer toxicant through grooming and trophallaxis

Answer

Delayed-action baits allow poisoned workers to return to the nest and share toxicant with nestmates, reproductives, and brood via social behaviors.
