不同药剂防治设施蔬菜主要害虫温室白粉虱的防效

[目的]通过田间试验明确试验药剂对设施蔬菜主要害虫温室白粉虱的田间防效,为生产应用提供参考.[方法]试验采用随机区组排列,每小区选取植株上、中、下叶片共固定10株,调查叶片背部的若虫数.药前调查1次,药后1、3、7、10、15d分别调查各处理小区定点株上残留活虫数,计算虫口减退率,并与对照区比较,计算校正防治效果.[结果]在冬季南疆温室大棚中,亩旺特防效最好,防治后15 d最高防效达到86.69;;1.8;阿维菌素EC次之,防治后15 d最高防效为".92;,阿克泰在药后ld的防效高于亩旺特和阿维菌素.在夏季北疆温室大棚中,阿克泰防效最好,防治后15 d最高防效达到91.11;;1.8;阿维菌素EC次之,防治后10 d最高防效达到86.84;,亩旺特防治后15 d最高防效达到81.32;,[结论]防治温室白粉虱,可采用阿克苏、亩旺特、阿维菌素3种化学农药在当地替代常用药剂或与其交替使用进行防治.

The Pesticide effect of Different Insecticides on Controlling Trialeurodes vaporariorum Westwood in Vegetable Plot in Xinjiang

【Objective】 The development of vegetables greenhouse and greenhouse techniquesin the north of China objectively formed the conditions for overwintering and reprogation of Trialeurodes vaporariorum Westwood.The trialeurodes vaporariorum Westwood were reproducedquickly,they were hard to be controlled,when spraying with pesticide,they quickly flied off;For many years,even if they were repeatedly controlled by various ways,but hey reproduced themselves as always.Even though the dosages applied in pratical production were continuously increased,the pesticide effect of common fungicides significantly were reduced.There were superstandard of pesticide residues on the vegetables,which could pollute environment and were harmful to human health.The test of pesticide effects of 3 fungicides with high-efficiency and low-toxicity controlling Trialeurodes vaporariorum Westwood in field was conducted in Sule county and Qapqal county in Xinjiang in 2010.【Method】 The test in greenhouse were carried out to test the pesticide effect on two tomatoes with Trialeurodes vaporariorum Westwood which occurred in South and North Xinjiang,The test was randemly divided into treated group and control group.【Result】 In the greenhouse of South Xinjiang in winter the result indicated that the control effect of Muwangte was the best,the highest control effect after 15 days reached 86.69%,1.8 Aweijunsu EC was the second,the highest control effect after 15 days was 65.92%.The control effect of Aketai was higher than that of Muwengte and Aweijunsu after 1 day.In the greenhouse of North Xinjiang in summer,the control effect of Akafai was the best,its control effect reached 91.11% after 15 days;1.8% Aweijunsu EC was the second,its control effect reached 86.84% after 10 days;the highest control effect of Munangte reached 81.32% after 15 days.【Conclusion】 The Trialeurodes vaporariorum Westwood could be controlled with the above 3 pesticides,which replace the commom ones or the both pesticides were used alternately to control trialeurodes vaporariorium Westwood.
