美洲斑潜蝇是危害瓜果蔬菜的毁灭性害虫。该虫食性杂,繁殖力强,由于其幼虫大量取食叶肉,影响叶片的光合作用,因而造成作物的产量和品质下降,甚至失收。近几年来,该虫在杭州地区暴发,给蔬菜生产造成严重损失。为了探索化学药剂对该虫的防治效果,筛选出高效安全低毒的农药,我们于1997年9月15日、10月5日分两次做了试验,现总结如下: Liriomyza sativae is a devastating pest that affects fruits and vegetables. The worm diet, reproductive ability, due to its larvae feeding large amounts of leaf meat, affecting leaf photosynthesis, resulting in crop yield and quality decline, or even lost. In recent years, the insect outbreak in Hangzhou, causing serious losses to vegetable production. In order to explore the effect of chemical agents on the prevention and control of the insects, screening of pesticides with high safety, low toxicity and toxicity, we conducted the test in two separate tests on September 15, 1997 and October 5, 1997, and summarized as follows:
