Effects of Sublethal Doses of Chlorpyrifos-methyl on the Following Generation of the Beet Armyworm, Spodoptera exigus (Hubner)
아치사량의 chlorpyrifos-methyl이 파밤나방(Spodoptera exigua(Hubner)) 차세대형성에 미치는 영향
Abstract
Chemosterilant effect of chlorpyrifos-methyl (CPM) on the beet armyworm, Spodoptera e.rigua (Hubner) was investigated, using topical application. Egg fecundity and fertility were analyzed in the adults reared from the fifth instar larvae which were treated with sublethal doses of CPM. Though CPM reduced fecundity a little, it gave significant negative effect on egg fertility in a dose-dependent manner. Genetic analysis was performed by reciprocal crosses between treated (100 Wgllarva) and untreated individuals and showed a dominant lethal effect of CPM on egg fecundity and fertility. This results indicate that chlorpyrifos-methyl may act as a chemosterilant as well as a well-known neurotoxicant, and suggest that it can be used in genetic control program.
