The influence of non-steroidal ecdysteroid agonists on Indianmeal moth larvae was assessed by rearing last instar larvae on diet treated with RH-5992 (tebufenozide) or RH-2485 (methoxyfenozide). Larvae were monitored for effects of the ecdysteroid agonists on weight, metamorphosis and mortality. Larvae treated with either of the ecdysteroid agonists at a concentration of 5 ppm or higher gained less weight and had greater mortality than did larvae reared on control diet. For example, the weights… Expand
Effects of atrazine and endosulfan sulphate on the ecdysteroid system of Daphnia magna.
TLDR
It is suggested that atrazine promotes its toxicity without interfering with the ecdysteroid activity of the crustacean, while endosulfan sulphate is an anti-ecdysteroidal compound for D. magna. Expand
Methoprene and 20-OH-ecdysone affect male production in Daphnia pulex.
TLDR
The results suggest that juvenile hormone and ecdysteroids might play a role in the Daphnia sex determination system. Expand
Biological Activity of Insect Growth Regulators , Pyriproxyfen , Lufenuron and Methoxyfenozide against Tribolium castaneum ( Herbst )
Three insect growth regulators (IGRs), juvenile hormone analogues (pyriproxyfen), ecdysone agonist (methoxyfenozide) and chitin synthesis inhibitor (lufenuron) were tested against egg, larva, pupaExpand
Comparative toxicity and ecdysone receptor affinity of non-steroidal ecdysone agonists and 20-hydroxyecdysone in Chironomus tentans.
TLDR
The results indicate that the increased toxicity of the non-steroidal ecdysone agonists for C. tentans has a high correlation to the affinity of these compounds for CtEcR/CtUSP bacterially expressed proteins. Expand
Effect of Artemisia Annua L. (Asterales: Asteraceae) Essential Oil on Mortality, Development, Reproduction and Energy Reserves of Plodia Interpunctella (H u bner).(Lepidoptera: Pyralidae)
TLDR
The sub lethal doses of essential oil showed that essential oil reduced adult emergence, longevity of male and female insects, fecundity and fertility of females, and there was no difference in mortality on either sex. Expand
Juvenile hormone and juvenile hormone mimics inhibit proliferation in a lepidopteran imaginal disc cell line.
TLDR
The imaginal disc-derived cell line, IAL-PID2, was discovered that the cell line was responsive to JH and a variety of JH mimics, and inhibition of cell proliferation in the absence of 20-hydroxyecdysone was obtained. Expand
Efficacy of insect growth regulators as grain protectants against two stored-product pests in wheat and maize.
TLDR
Temperature at the levels examined in the present study did not appear to affect the overall performance in a great extent of the tested IGRs in terms of adult mortality or suppression of progeny production against P. truncatus in treated maize. Expand
Imaginal Discs and Tissue Cultures as Targets for Insecticide Action
TLDR
This chapter focuses primarily on the use of imaginal discs, in vivo and in vitro, for investigating the action of IGRs, and evaluates novel bioassays that show promise for determining the selectivity and mode of action of candidate insecticides. Expand
Residual Efficacy of Pyriproxyfen on Grain Commodities Against Stored Product Insect Pests
TLDR
Results show that pyriproxyfen has potential for residual control of O. surinamensis, T. castaneum and T.granarium, and may be used for replacement of conventional neurotoxic insecticides for managing the insect pests of stored commodities. Expand
INSECT GROWTH REGULATORS
TLDR
The classical scheme that was developed by these scientists was that a hormone from the brain stimulated the prothoracic glands to release a molting hormone, which caused either molting or metamorphosis depending upon the stage of the insect, and in particular, on whether a third hormone, juvenile hormone, was present.

RH 5849, a Nonsteroidal Ecdysone Agonist: Effects on Larval Lepidoptera.
TLDR
RH 5849 and its analogs are relatively persistent ecdysone agonists that halt feeding in larval lepidoptera by forcing an ultimately lethal, developmentally premature molt. Expand
Action of RH 5849, a non-steroidal ecdysteroid mimic on Plodia interpunctella (Hübner) in vivo and in vitro.
TLDR
It is concluded that RH 5849 exhibits molting hormone activity in vivo as well as in vitro, however, the toxicological effects in P. interpuncetella result from action on feeding and growth, rather than molting. Expand
Effect of the Nonsteroidal Ecdysone Agonists, Methoxyfenozide and Tebufenozide, on the European Corn Borer (Lepidoptera: Pyralidae)
TLDR
Methoxyfenozide and tebufenozide are potential insect growth regulators for controlling O. nubilalis and are found to be toxic to newly hatched larvae of the European corn borer. Expand

Effect of chitin‐synthesis inhibitors on stored‐product beetles
TLDR
Chlorfluazuron provided the most effective control of all four stored-product pest species, including the weevil, S. oryzae, after exposure to wheat treated with five benzoylphenyl ureas (BPUs), members of the chitin-synthesis inhibitor group of insect growth regulators (IGRs). Expand
RH 5849, a nonsteroidal ecdysone agonist: effects on a Drosophila cell line.
TLDR
Although it is less potent than 20-hydroxyecdysone in both whole-cell and cell-free receptor assays, RH 5849 is the first nonsteroidal ecdysone agonist. Expand
