本研究结果 :①美洲斑潜蝇和南美斑潜蝇共有寄主植物 2 1科 80种 ,其中混合发生寄主植物有 11科 4 9种 ;②温度是制约其发生为害的主要因子 ,冬暖大棚是其冬季及早春继续发生为害的重要场所 ,并成为露地发生的主要虫源 ;③在发生区内 ,主要通过自然传播扩散 ;④ .8%阿巴丁、1%海正灭虫灵对两种斑潜蝇防治效果较好 ,达 95 %以上 ;⑤控制为害应强化植物检疫 ,选用以生物农药为主的农药品种 ,在适期内 ,狠抓冬暖大棚和豆科、葫芦科、伞型花科、菊科、蓼科等主要寄主作物的早期防治和连续防治的综合措施。
The results of this study are as follows: ① There are 80 families of host plants, 21 families and 20 host plants, of which there are 11 families and 49 species of host plants mixed together. ② Temperature is the main factor restricting their occurrence and damage. Its winter and early spring continue to occur as an important place of harm, and become the main source of exposure to the open field; in the occurrence of the area, mainly through natural diffusion; ④ .8% Abadin, 1% The control effect of Liriomyza sativae is better than 95%. ⑤ Controlling the harm should strengthen the phytosanitary measures. Select the pesticide varieties mainly based on biological pesticides. Pay close attention to winter warm shed and legumes, Cucurbitaceae, umbrella type Flowering, Asteraceae, Polygonaceae and other major host crops, the early prevention and control and integrated measures of continuous control.
