烟台市美洲斑潜蝇和南美斑潜蝇的混合发生与防治适期的研究

Study on Mixed Occurrence and Proper Controlling Time About Lirimyza Huidobrensis Blunchard and Liriomyza Sativae Blunchard

本研究结果 :①美洲斑潜蝇和南美斑潜蝇共有寄主植物 2 4科 87种 ,其中混合发生为害寄主植物有 1 1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防治两种斑潜蝇应贯彻“预防保护”方针 ,狠抓冬暖大棚和主要寄主作物的早防治和连续防治 ,减少虫源 。

The result showed ①Host plants of Lirimyza huidobrensis Blunchard and Liriomyza sativae Blunchard include together 80 species 21 families, in which mixed occur include 49 species,11 families. ②Temperature is the main factor affecting its occurrence. Winter-warm shed becomes the main place surviving in winter and early spring, continuous damages and main pest source in the open. ③They extend by means of natural spread in occurrence area. ④The key methods that control damage is carrying out the policy of “putting prevention fist, multiplying control” in plant protection work. Strengthen plant quarantine, take the measures that choosing biological insecticides, grasping host plants pea ,gourd and umbelliferea compositae families vegetables in winter-warm shed ,controlling early or continuously.
