摘要/Abstract

摘要：

化学防治是世界各地防治小菜蛾Plutella xylostella (L.)的主要方法。选择对小菜蛾各发育阶段高效的杀虫剂有助于很好地控制这一害虫。本研究用浸叶法测定了茚虫威和六伏隆对小菜蛾卵、幼虫和成虫的毒性。茚虫威和六伏隆对小菜蛾卵的LC₅₀值分别为201.40 和 37.32 mg/L。茚虫威和六伏隆对3龄幼虫也有很好的毒性（茚虫威的LC₅₀ 为 4.82 mg/L; 六伏隆的LC₅₀ 为1.48 mg/L)。对成虫的毒性结果表明, 这两种杀虫剂对成虫均没有理想的毒性（茚虫威的LC₅₀ 为845.20 mg/L; 六伏隆的LC₅₀ 为3 438 mg/L)。根据计算的LC₅₀值, 六伏隆对小菜蛾卵和幼虫的毒性比茚虫威高, 但是茚虫威对成虫的毒性更高。

Abstract:

Chemical control is the mainly control method for Plutella xylostella (L.) throughout the world. Choosing insecticides with high efficacy on all stages of this pest can help us control it well. In this case, toxicities of indoxacarb and hexaflumuron on eggs, larvae and adults of P. xylostella were studied with leaf dip method. The LC₅₀ values of egg stage for indoxacarb and hexaflumuron were 201.40 and 37.32 mg/L, respectively. Also indoxacarb and hexaflumuron had excellent toxicity on the 3rd larval instar (LC₅₀: indoxacarb=4.82 mg/L, hexaflumuron=1.48 mg/L). Results of moth toxicity indicated that above insecticides had no acceptable toxicity on this insect (LC₅₀: indoxacarb=845.20 mg/L, hexaflumuron=3 438 mg/L). According to the calculated LC₅₀ values, hexaflumuron was more toxic than indoxacarb to eggs and larvae of diamondback moth but at the adult stage the indoxacarb was more toxic.
