In vitro effect of nonsteroidal ecdysone agonist RH 5849 on fat body acid phosphatase activity in rice moth, Corcyra cephalonica (Insecta).

Nonsteroidal ecdysone agonist stimulates acid phosphatase activity in the fat body in vitro cultures obtained from ligated late-last instar larvae of Corcyra cephalonica. The agonist also stimulates general protein synthesis. This stimulation is both time as well as dose dependent (up to a dose of 1000 ng of the agonist). However, still higher concentrations (1500-4000 ng) tend to depress the degree of stimulation.
