重阳木斑蛾是重阳木的一种最重要害虫。此虫在福建福州常间歇性猖獗发生为害,一年发生四代,一至三代严重害叶。以不同龄期的幼虫在枝干裂缝、木栓层下及粘叠的叶片间越冬,极少数化蛹越冬。冬季气温达8℃以上时,越冬幼虫仍能少量取食,无明显的仃育。成虫产卵于枝干皮下,卵期6—15天。幼虫共6—8龄,幼虫期33—34天(第1—3代)及137天(第4代,即越冬代);蛹期10—20天;成虫寿命长者13天。本文对各虫期形态和生活习性有较详细的记述。天敌有:卵寄生蜂;绒茧蜂Apanteles sp.和另一种茧蜂及日本追寄蝇Exorista iaponica T.-T.等两种寄蝇寄生于幼虫;横带沟姬蜂Goryphus basilaris Holmgren寄生于蛹。人工捕杀、清洁园地、保护天敌和喷撤六六六等农药,防治效果都很好。
Chlamydomonas is one of the most important pests of Chongyang wood. The insects often occur in Fuzhou, Fujian often intermittent rampant, four generations a year, one to three generations of serious leaf damage. In different age larvae in the branch stem cracks, cork layer and sticky foliage overwintering, very few pupation wintering. Winter temperatures of 8 ℃ or more, overwintering larvae can still eat a small amount, no obvious Ding Yu. Adult spawning branches in the skin, the egg period 6-15 days. Larvae 6-8 years old, larvae 33-34 days (1-3th generation) and 137 days (4th generation, that is, overwintering generation); pupal period 10-20 days; adult life expectancy 13 days. This article describes the morphological and living habits of each stage in more detail. The natural enemies are: eggs parasitic wasp; Apanteles sp. And another kind of beetles and Japan chasing the fly Exorista iaponica T.-T. and other two kinds of parasitic parasitic on larvae; horizontal ditch G was bee parasites in Goryphus basilaris Holmgren pupa. Manually killing, cleaning the garden, protecting natural enemies and spraying six hundred sixty-six and other pesticides, prevention and treatment are good.
