The effects of two pyrethroids, deltamethrin and cyfluthrin, on the development of two insects: Blattella germanica L. and Spodoptera littoralis Boisd


, : The effects of two pyrethroids, deltamethrin and cyfluthrin, on the development of two insects: Blattella germanica L. and Spodoptera littoralis Boisd. Mededelingen van de Faculteit Landbouwwetenschappen, Rijksuniversiteit Gent 54(3b): 1029-1038

The effects of cyfluthrin at LD10, LD50 and LD90 dosages on the physiology of reproduction and development of Blattella germanica were studied in the laboratory. Individuals that survived treatment showed reduced fecundity and fertility (16-71%), prolonged postembryonic development (4-21%) and reduced increase in weight (14-28%).

Aubry, M.; Echaubard, M.; Porcheron, P., 1991: Effects of deltamethrin on certain biochemical parameters of larval development in Spodoptera littoralis (Boisd.) (Lepidoptera, Noctuidae). The insecticide deltamethrin was applied topically at the LD10 (0.5 ng) to larvae of Spodoptera littoralis in their penultimate instar 2 h after ecdysis. Within the 1st 10 h of treatment, larvae lost 15% of their body weight (30% compared with unt...

Bernard, L.; Lagadic, L.; Echaubard, M., 1991: Effects of cyfluthrin on growth and food consumption in the 4th larval instar of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). The insecticide cyfluthrin was administered to 4th-instar larvae of Spodoptera littoralis by incorporating the LD15 into an artificial diet. Growth rate was reduced, and changes occurred in a range of food consumption indices (relative consumption...
