摘要:
黄杨绢野螟在如皋市1 a发生3代,以第3代1龄或2龄幼虫将2—3片瓜子黄杨叶片吐丝叠成虫苞在内结薄茧越冬,翌年3月上旬开始出蛰危害。1代低龄幼虫高峰期为5月底至6月上旬,2代低龄幼虫高峰期为7月中下旬,3代低龄幼虫高峰期为9月上中旬, 10月中下旬进入越冬期。越冬代成虫5月上旬羽化,越冬代和第1代羽化高峰期明显,第2代成虫羽化期长,羽化高峰不明显,10月中旬羽化结束。4种农药林间防治试验表明:药后5 d,1.1%甲氨基阿维菌素苯甲酸盐2 000 倍、2.5%高效氟氯氰菊酯2 000倍、90%敌百虫晶体1 000 倍防治效果均在95%以上,而1%苦参碱水剂1 000 倍防治效果较低,其中甲氨基阿维菌素苯甲酸盐、敌百虫晶体对黄杨绢野螟击倒快速,生产中优先使用生物农药甲氨基阿维菌素苯甲酸盐。
Abstract:
Diaphania perspectalis has 3 generations annually in Rugao City, overwintered by 1 or 2 instars larva of the third generation. The larva hibernates in the hibernaculum, which is a thin cocoon, whose outside is a bract of 2-3 Buxus sinica leaves after silking. It takes activities and damages by early March the next year. The larva peak of the first generation occurs from the end of May to early June. The second generation larva peak appears from middle of July to late July. The larva peak of the third generation appears within former twenty days of September, overwintering by middle or late October. Early May is the period of overwintering adult eclosion. The eclosion of overwintering generation and the first generation features obvious peak. The second generation eclosion period is long while it’s eclosion peak is not obvious, and the eclosion ends in mid-October. The test resulted from forest control trial by 4 pesticides showed that the control effects of spraying 1.1% emamectin benzoate 2 000 times, 2.5% beta-cyfluthrin 2 000 times, 90% crystal trichlorfon 1 000 times, were all more than 95% after 5 days. Among them, emamectin benzoate and trichlorfon acted faster than beta-cyfluthrin. As a kind of bio-insecticide, emamectin benzoate is preferred in production.
