摘要
对8种杀虫剂防治美洲斑潜蝇的药效进行了对比试验。结果表明,8种药剂在室内防治美洲斑潜蝇低龄幼虫和成虫的效果明显高于3龄幼虫,其中,斑蛾清不仅速效性强,而且持续时间长;阿维菌素、灭蝇胺虽然药效比较迟缓,但持续时间较长,防效都能达到90%以上,总的防治效果较好;毒死蜱、杀虫双速效性好,药后1 d的死亡率均达到80%以上,但防效期不长,总的防治效果不如前3种药剂;速灭杀丁的防效一般,效果最差的是乐果。
The result of chemicals test indicated that the 1st instars,2nd instars and adult of Liriomyza sativae were more sensitivitive to the 8 insecticides than those in the 3rd instars.Ban＇eqing showed its effects not only rapid but also persistent; while the action of avermetin and cyromazine were slow but the effect permanent,the affection exceed 90％.Chlorpyrifos and dimehypo could kill pests rapidly,the mortality of pests was up to 80％ after 1 day; but the effect failed to last long,and they were not so good as the above mentioned 3 pesticides.The fenvalerate was of the average,while the dimethoate the worst one.
