通过 1 998～ 2 0 0 0年对拉美斑潜蝇的研究结果表明 :①寄主植物有伞形花科等 1 6科 68种 ,温度是制约其发生的主要因子 ,不能在自然环境条件下越冬 ,但可在冬暖大棚内越冬和继续发生为害 ,成为露地发生主要虫源 ,通过自然传播扩散 ;②控制为害的关键技术是 ,选用以生物农药为主的农药品种 ,对冬暖大棚及伞形花科、豆科及葫芦科等受害重的菜田进行集中治理 ,做到早防治和连续防治的综合措施 ;③ 3年共累计防治面积 50 0 0 0hm2 ,其经济、生态和社会效益显著
The results of the study on the leaf miner in Latin America from 1998 to 2000 showed that: (1) The host plants were 16 families and 68 families (16 families). The temperature was the main factor that restricted their occurrence and could not win the winter in the natural environment , But can survive winter in the winter warmth and continue to happen, become the main source of exposure to the open field, spread through the natural spread; ② control of the key technologies is to use pesticides based on bio-pesticide varieties, the warm winter sheds and umbrellas 3-year cumulative total control area of 50000hm2, and its economic, ecological and social benefits were significantly higher than that of the control group
