摘　　要：葡萄“小叶症”是由侧杂食线螨[Polyphagotarsontmns latus(Banks)]危害所致。该螨以雌成螨越冬,世代循环周期6～7天,6～8月危害葡萄,以巨峰系列品种受害最重。消长峰值与其它作物生长盛期相吻合,发生量受虫口基数和大雨、暴雨的影响。用“克螨特”、“喳流磷”等杀螨剂坚持“四防”措施可有效的控制其危害。Small leaf' diseaec on grape vine was caused by the yollow mito (Polyphagotarson-emus latus (Bank) from June to August. Grape variety 'Jufeng' damaged by the mite most severely. After the female adult mite survived the winter, the generation cycles lasted for 6-7 days. The peak value of population fluctuation coincided with the growth peak time of other crops. The occuring population density was affected by the incipient population density and heavy rain. The use of propagite, quinalphos and ot the miticides and the persi stence in four othermethods could controlled the yellow mite on grape vine effectively.
