The chemical structure of azadirachtin is similar to that of
ecdysone, an insect hormone that regulates metamorphosis.
-
Ecdysone agonists (methoxyfenozide and tebufenozoide) are on second place in term of their effectiveness after CSIs.
This insecticide acts as
ecdysone agonist (antimoulting).
Developmental regulation of
ecdysone receptor (EcR) and EcR-controlled gene expression during pharate-adult development of honeybees (Apis mellifera).
aerogene, and Serratia marcesensesi with active compounds included a-sitosterol, hydroxy
ecdysone, ecdysterone, and giloinsterol (39,40).
In the assay, 20E and
ecdysone are nearly equally recognized by the polyclonal AS 4919 antibodies used (Porcheron et al.
Ecdysone: Structures and Functions Chapter 23:551-578.
The diacyl hydrazines act as
ecdysone antagonists, promoting acceleration in the ecdysis process (Dhadialla et al.
The expression of Pc-14-3-3 was significantly up-regulated in hepatopancreas after eyestalk ablation or
ecdysone induction, which was confirmed by qRT-PCR and western blot analysis.
In the CC-CA of mosquitoes, the expression of the following receptors has been detected: ETH A and B,
ecdysone A and B, insulin, ultraspiracle A and B, allatotropin, AST-C A and B, and the short neuropeptide F.
To date, only one BTB protein, broad complex (BR-C) protein of the BTB-ZF subfamily, has been identified in the silkworm, where it has been shown to mediate
ecdysone signaling [29, 30].
