美洲斑潜蝇(Liriomyzd Sativae Blanchrd)是严重为害瓜果蔬菜类作物的检疫性害虫,自1993年12月在海南省三亚市首次发生以来,已逐步蔓延到全国21个省(市、区)。我市于1994年传人该虫后,为害程度不断加剧,尤其对夏秋季豆科、葫芦科、十字花科等蔬菜为害更重。我们在1997～1998两年,选择了6种化学及生物型杀虫剂进行对比试验,取得了较为显著的防治效果。 Liriomyzd Sativae Blanchrd is a quarantine pest which seriously damages fruits and vegetables. Since it first occurred in Sanya City, Hainan Province in December 1993, it has gradually spread to 21 provinces (cities and districts) across the country. After the succession of the pest in 1994, our city intensified the degree of harm, especially for the summer and autumn legumes, Cucurbitaceae, Cruciferae and other vegetables harder. In the two years from 1997 to 1998, we selected six kinds of chemical and biological pesticides for comparative experiments and achieved more significant control effects.
