摘　　要：[目的]研究苦参碱对棉蚜的防治效果。[方法]以棉花品种新陆早33号为供试作物,研究0.3%苦参碱、25%阿克泰WG、0.5%啶虫脒(对照药剂)4、0%氧化乐果对棉蚜的防治效果。[结果]0.5%啶虫脒、0.3%苦参碱、25%阿克泰WG施药后37、1、5 d的虫口减退率分别为94.5%、97.1%、85.4%,90.8%、91.5%、87.7%和91.6%、93.5%、85.4%,校正防效分别为95%、99.5%、96.9%,91.2%、91.5%、98.9%和92.0%、96.7%、96.7%,40%氧化乐果对棉蚜的防治效果较差;苦参碱和阿克泰施药后第37、d对蚜虫的校正防效低于对照药剂,但施药后第15 d,苦参碱对蚜虫的校正防效高于对照药剂,阿克泰对蚜虫的校正防效与对照药剂相当。[结论]生物农药苦参碱防治蚜虫见效较慢,但其持效期长、环境污染小。[ Objective] The aim was to study the control effect of rmtrine on cotton aphid. [ Method] With cotton variety Xinluzao33 as the tested crop, the control effects of 0.3% matrine, 25% Actara WG, 0.5% acelamipfid （control pesticides） and 40% omethcate on cotton aphid were studied. [Result] After 3, 7, 15 d of pesticides application, the decresae rates of cotton aphid trcated by 0.5% acetamiprid, 0.3% matrine and 25% Actara WG were 94.5 %, 97.1%, 85.4 % and 90.8 %, 91.5 %, 87.7 % and 91.6%, 93.5 %, 85.4 % resp., and their correction control effect on cotton aphid were 95%, 99.5%, 96.9% and 91.2%, 91.5%, 98.9% and 92.0%, 96.7%, 96.7%, the control effect of 40% omethoate on cotton aphid was worse. 2he correction control effect of watrilre and Aetara on cotton aphid were lower than that of control pesticides after 3, 7 d of pesticides application, but after15 d of pesticides application, the correction control effect of matrine on cotton aphid was higher than that of control pesticides, and that of Actara was equal with that of control pesticides. [ Conclusion] When biological pesticide matrine was used to control cotton aphid, the effect was slower, but the persistent period of it was longer with less environmental pollution.
