The Western corn rootworm, Diabrotica virgifera virgifera, is one of the most devastating corn rootworm species in North America, especially in the midwestern corn-growing areas such as Iowa. A related species, the Northern corn rootworm, D. barberi , co-inhabits in much of the range and is fairly similar in biology.

Diapause in insects is a dynamic process consisting of several distinct phases. While diapause varies considerably from one taxon of insects to another, these phases can be characterized by particular sets of metabolic processes and responsiveness of the insect to certain environmental stimuli. [6]
Chlorethoxyfos (O,O-diethyl-O-(1,2,2,2-tetrachloroethyl)phosphorothioate) is an organophosphate acetylcholinesterase inhibitor used as an insecticide.It is registered for the control of corn rootworms, wireworms, cutworms, seed corn maggot, white grubs and symphylans on corn.

These fall into three classes: allatostatin A, [11] allatostatin B, [12] and allatostatin C [13] (for a review of these control mechanisms see: Stay and Woodhead 1993). [14] Secondary control of the JH titre found in the haemolymph of the developing insect is metabolic inactivation of JH by JH-specific esterase and juvenile hormone epoxide ...
