摘要 棉古毒蛾Orgyia postica(Walker)是黑荆树的重要害虫。在福建一年发生6代,以幼虫越冬,翌年3月上旬化蛹。幼虫5龄,少数4龄。在林间幼虫常感染核型多角体病毒,造成病毒病流行,是控制此虫种群的重要因素。枯叶蛾绒茧蜂Apanteles liparidis (Bouche)、荞麦毒蛾细颚姬蜂Enicospilus striolatus Townes是主要寄生天敌。辛硫磷,溴氰菊脂和核型多角体病毒对幼虫均有良好效果。 The tussock moth Orgyia postica (Walker) is a serious pest of Acacia mearnsii in Fujian Province. It has six generations a year and overwinters as larvae. The overwintering larvae begin to pupate in early March next year. The larvae generally have five instars,but a few of them only have four instars Th elarvae are often infected with a Nuclear polyhedrosis virus in the forest so that they often reaches epizootic levels in natural populations. Thus it is an important factor in controlling the population of this pest. Apanteles li-paridis ( Bouche ) and Enicospilus striolatus Townes are major natural enemy of the tussock moth. The effective measures to control the larvae are spraying with Phoxim, Deltamethrin, Nuclear polyhedrosis virus of Orgyia postica.
