【摘要】 甘薯天峨HerseconvolvuliLinnaeus在山东省一年发生4代，以蛹在土壤中越冬，各虫态历期：以越冬代卵期最长，平均为6．2d，第一代卵期为5．6d，第二、三代卵期分别为3．6和3．4d。幼虫也以越冬代历期最长，为22．0d，第一代为15．6d，第二、三代历期分别为11．6和13d。成虫有超光性，对糖醋液和杨树枝把无趋性。以2．5％敌杀死、45％马拉硫磷乳油和BT防治效果较好，防效可达85％以上。更多还原

【Abstract】 Four generations of Herse convolvuli Linnaeus occur one year in Shandong Province. Pupa pass the winter in soil,in the course of every development stage,the egg stage of overwintering generation is the longest,it averages 6. 2 days;the egg stage of first generation is 5.6 days;the egg stage of the second and the third generation are 3.6 and 3. 4 days respectively- The larval stage of overwintering generation is the longest,22.0 days,the larval stage of the first generation is 15. 6 days,the larval stage of the sec-ond and the third generation are 11. 6 days and 13 days respectively. The adult has pho-totaxis,but no taxis to sugar-vinegar and branch bind of poplar. The control effects of 2.5 % Deltame thrin, 45% Malathion and Bt are over 85 %,much better than other pesti-cides that have been tested.更多还原
