Mh. Ross, RESPONSE OF BEHAVIORALLY RESISTANT GERMAN COCKROACHES (DICTYOPTERA, BLATTELLIDAE) TO THE ACTIVE INGREDIENT IN A COMMERCIAL BAIT, Journal of economic entomology, 91(1), 1998, pp. 150-152
Previous study showed that German cockroaches, Blattella germanica (L.
), evolved behavioral resistance to a chlorpyrifos-based commercial ba
it. Feeding experiments with chorpyrifos-treated dog chow were underta
ken to determine whether cockroaches avoided the active ingredient or
a base ingredient. The results indicate that resistance was caused by
aversion to the active ingredient.
