A laboratory study of insect growth regulators against the diamond-back moth, Plutella xylostella (Plutellidae) larvae

, : A laboratory study of insect growth regulators against the diamond-back moth, Plutella xylostella (Plutellidae) larvae. Malaysian Journal of Applied Biology 10(1): 57-62

In the laboratory at Minden on Penang Island, West Malaysia, the relative effectiveness of 5 juvenile-hormone analogues was tested by ingestion against mature larvae of Plutella xylostella (L.) on Chinese cabbage. Hydroprene (ZR-512), which was used as a standard of reference, was more effective than any of the other analogues, the next most effective being methoprene (ZR-515), followed by ZR-520 (ethyl (2E,4E)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate).

The effect of toosendanin, a presynaptic blocker, on the inward rectifier potassium channel (KKir) of hippocampal CA1 pyramidal neurons of rats was studied by the single-channel patch-clamp technique. The results showed that toosendanin had an inh...
