调查美洲斑潜蝇(LiriomyzasativaeBlanchard)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 investigation of the growth and decline of Liriomyzasativae Blanchard occurred in the field. The results showed that the insect was the main hazard to Solanaceae, Leguminosae and Cucurbitaceae vegetables. Danzhou in Hainan Danger occurred throughout the year, from February to May is the peak of danger, insect population density and temperature, natural enemies are negatively correlated, that high temperature and natural enemies parasitic can inhibit the occurrence of Liriomyza sativae; its larvae field distribution consistent with Chennai (Core distribution) and negative binomial distribution. The insects were mainly spread by adults and spread with the host plants. 1.8% avermectin and 40% phoxim had better control effects on the leaf miner. Field Control effect of more than 80%.
