Abstract:
The effects of DPX-MP062 [methyl 7-chloro-2,3,4a,5-tetrahydro-2[methoxycarbonyl(4-trifluoromethoxyphenyl)carba moyl] indeno[1,2-e] [1,3,4] oxadiazine-4a-carboxylate] a broad-spectrum insecticide with a novel mode of action, on the Egyptian cotton leafworm, Spodoptera littoralis, were studied in laboratory experiments. Egg hatch was affected by high concentrations (125 mg AI litre-1) of DPX-MP062. Larvae that hatched from treated eggs were significantly affected at concentrations of 12.5 mg AI litre-1 and greater. Larvae were fed castor bean leaves treated with DPX-MP062; 1st-instar larvae were the most susceptible development stage. Pupation and adult formation were determined in assays with 5th-instar larvae. There was strong suppression of adult formation; 65 and 91% at 0.5 and 0.75 mg AI litre-2, respectively. Highly affected larvae died before pupation; slightly affected ones reached pupation 2-4 days later, were smaller than larvae in the untreated control, and were sometimes unable to develop into normal adults. Comparatively high concentrations (50 and 100 mg AI litre-1) of the test compound were necessary to affect adults by ingestion, but no effects from contact application could be determined at a concentration of 100 mg AI litre-1.
