摘要
古毒蛾（Orgyia antiquae）是柴达木盆地近年来发生的一种新的危害白刺的害虫,该虫在青海省德令哈地区1年发生1代,以卵越冬,幼虫共有6个龄期。在自然条件下,幼虫各龄发育历期平均为5 d左右,蛹期平均为12 d,成虫寿命约6 d,完成1代约50 d。幼虫期防治试验表明：阿维菌素乳油4000～6000倍液和高效氯氰菊酯乳油2000～2500倍液防治效果较好,平均防效均在90%以上。
Orgyia antique is a newly found insect attacking the Nitraria in Caidamu basin of Qinghai Province.It has 1 generation a year in Delingha and overwinterings as eggs in the cocoons.The larvae of Orgyia antique have 6 instars.In the field,a life cycle of the Orgyia antique required 5days as each instars,12 days as pupae and 6 days as adult.The control experiment in the larval period was made,the result showed ：the dilute multiple of the Avamectin should be 4000 to 6000,the Alphacypermethrin should be 2000 to 2500,and effect was above 90%.
