摘要
试验在暴露的成虫期进行,使用烟剂、超低容量喷雾和常规喷雾三种方法,选用了8种农药的不同浓度和剂量。施药后12、24、36小时检验杀虫效果。结果显示,敌马烟剂杀虫效果高于741烟剂;超低容量喷雾药效从好到差依次为:80%敌敌畏、50%马拉硫磷、40%氧化乐果、20%速灭杀丁。
The present experiment applied three techniques to spread in- secticides to the adults of Megastigmus sabinae (Hymenoptera,Chalcidoidea, Torymidae)for control,i.e.the smoking,the ultra-low-volume spraying and the normal-volume spraying,with eight different insecticides and different concentration and doses.The control effect were checked after 12,24 and 36 hours of treating respectively.The results showed that.DDVP-T.M.4049 was better than the somke 741;the best insecticide with high mortality of the wasp in the ultrà-low-volume spraying techniques was 80% Dichlorphos,and then 50%Malathion,40%Dimethoate and 20% Sumicidin successively
