Abstract |
This work was done to evaluate the short term and latent bioeffects of 4 insecticides on the black cutworm. A. ipsilon. These insecticides were Cyanophos. Fenvalerate, Prempet and Pyriproxyfen. Also, the performance and efficacy of these compounds on cutworm had been evaluated under field conditions. The obtained results revealed that, A. ipsilon 4th instar larvae was more sensitive to cyanophos than other tested compounds. LC50 values of these 4 compounds were 45.46, 60.69, 78.66 and 123.19 ppm of cyanophos, fenvalerate, prempet and pyriproxyfen, respectively. Mortality percentages increased as the tested concentration increased. Pyriproxyfen behaved as antifeedant agent, decreasing the weight of full-grown larvae. Fenvalerate and cyanophos increased weight of A. ipsilon pupae, while pyriproxyfen and prempet showed no obvious effect on the pupal weight, but caused failure in moulting of pupae. Pyriproxyfen and prempet decreased the percentages of pupation, percentages of emergency, numbers of deposited egg/female and percentages of hatchability. In field trials, prempet, fenvalerate and cyanophos were almost equi-toxic in poisonous baits for cutworm, while pyriproxyfen was the least effective in this respect.
