摘 要: | 采用生物测定法,比较了斜纹夜蛾NPV对取食芋叶等7科8种蔬菜的斜纹夜蛾幼虫的毒力反应差异性。结果表明NPV对取食番茄叶的幼虫毒力最高,比取食芋叶的毒力高6.82倍;但再经菜心饲养一代后,NPV的毒力差异消失。

Abstract: | Toxicity difference of cotton leafworm NPV to larvae of cotton leaf worm feeding on & vegetables of 7 families has been studied through bioassay. The results indicate that the toxicity difference is remarkable, and the LC_50 to the larvae feeding on tomato leaf is 6. 82 times higher than to the larvae feeding on taro leaf. But the toxicity difference disappeares when larvae feeding on Chinese flowering cabbage in next generation. |
