Research on Liriomyza huidobrensis Blanchardduring 1998- 2000 indicated that: ① its host plants belong to 68 species, 16 families including carrot family. Temperature is the main environmental element effective on its occurrence. The pest can not over winter under the local natural conditions, while in vegetable sheds with higher temperatures it survives the winter and damages during the season, as forming the origin of occurrence in oper vegetable plots. It disperses by means of natural spread. ②Applying insecticide, mainly biological insaticides, is one of key control measures on the pest. The vegetable sheds, as well as oper plots with serious damage on the plants of carrot, pulse and gourd families, culminated the management necessity. Early and continuous control should be emphasized. ③ In the study duration, plots implemented with control measures reach a total of 50000hm2 with significant economic, economical and social benefits.%通过1998～2000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16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；③3年共累计防治面积50000hm2，其经济、生态和社会效益显著。
