【摘要】 淡剑夜蛾[Sidemia depravata(Butler)]在上海地区年发生4-5代,世代重叠,以老熟幼虫和蛹在土中越冬;整个世代历期(第3代)33.3d(卵3.5d,幼虫18.9d,蛹5.7d,成虫5.2d);3龄前幼虫食量小,4龄后食量大增,特别是6龄期食量占总食量的91.3％。每年7、8、9三个月为幼虫危害高峰期,以高羊茅草坪受害最重。田间防治试验表明,10％除尽(Chlorfenapyr)SC、24％米满(Tebufenozide)SC、40％毒丝本(Chlorpyrifos)EC、5％卡死克(Flufenoxuron)EC和5％抑太保(Chlorfluazuron)EC1000-1500倍均有良好的防治效果。更多还原

【Abstract】 Sidemia depravata (Butler) occurs 4-5 generations every year in Shanghai area, the generations overlap and the old larvae and pupae are in the earth through the winter. The whole third genenation time is 33.3 days, in which eggs’3.5 days,larvae’s 18.9 days,pupae’s 5.7 days and adult’s 5.2 days.The larva has a small appetite before 3rd instar but after 4th instar its appetite increases greatly, and the capacity for eating in 6th instar is 91. 3% of total capacity for eating. The peak time of the larva damage occurs mainly in July, August and September every year, and the tall fescue is the most serious damaged among all the lawn. The field investigation results indicated that 10% Chlorfenapyr SC, 24% Tebufenozide SC, 40% Chlorpyri-fos EC, 5% Flufenoxuron EC and 5% Chlorfluazuron EC all had a good effect on control of the pest.更多还原
