The virus Egf gene encodes an enzyme that modifies a hydroxyl group on 20E, thereby inactivating the molting hormone and resulting in a delay or in the absence of molting in infected larvae (O'Reilly et al.
The sterol requirement of insects is, in most cases, satisfied by cholesterol (1), which is the principal sterol in insects and serves as the structural component of cell membranes and as biogenetic precursor of the molting hormone, 20-hydroxyecdysone (2).
CYP314A1, designated shade in Drosophila, is a 20-hydroxylase responsible for the conversion of ecdysone to active molting hormone, 20-hydroxyecdysone (Rewitz et al.
The ultimate goal--a baculovirus genetically engineered to infect a gypsy moth with large amounts of brain proteins that disrupt its normal molting hormone production--is probably years away.
This insecticide mimics the action of the molting hormone ecdysone, thus triggering premature molting of immature lifestages, particularly of Lepidoptera larvae.
There is no strong evidence to indicate that hormones are generally involved (Engelmann 1970), but in some moths, the molting hormone could facilitate the process by increasing the permeability of the wall of the testis to some macromolecular factors (Wilde & Loof 1973).
Levels of the molting hormone, ecdysone, were quantitated, using a radioimmunoassay (RIA), in hemolymph of animals exhibiting shell disease.
Granted, their reproduction is not regulated by steroids, but ecdysone, the molting hormone, is certainly a steroid.
