摘要
调查美洲斑潜蝇（Liriomyza sativae Blanchard)田间发生消长规律，结果表明，该虫主要危害茄科、豆科及葫芦科蔬菜。在海南儋州整年发生危害，2－5月份为危害高峰期，其虫口密度与温度、天敌成负相关，即高温和天敌寄生虫可抑制美洲斑潜蝇的发生；其幼虫田间分布型符合奈蔓A（核心分布）和负二项分布；该虫主要通过成虫飞翔和随寄主植物扩散而传播；1．8％爱福丁乳油和40％辛硫磷乳油防治美洲斑潜蝇的效果较好，田间防治效果达80％以上。
The vegetable leaf miner Liriomyza sative Blanchard is widely distributed in Hainan Is land.It is an important pest of vegetables.This pest was found to cause serious damage to host plants mainly including solanaceae,bean and gourd family.The pest causes dam age through out the year in Hainan Island,with the fastigium starting from February to May.The density of the pest is negative ly correlated with temperature and natural enemy,or the high temperature and massive nat ural ene mies would restrain Liriomyza sativae Blanchard occurrence.The infesting distribu tion pattern showed Neyman A distribution and negative bi nomial distribu tion.It spread by adult flying and host plants transference with its egg and larva,pupa.The result of pesti cides against the pest showed that the control efficacy of1.8%AifudinEC was83.9%.
