摘要
猕猴桃准透翅蛾(Paranthrene actinidiae Yang et Wang)是危害猕猴桃枝干的重要害虫,在江西庐山成年树受害率达95%以上,重株带虫30余头,每年一代,以2龄幼虫在枝条韧皮部(少数髓部)越冬,翌年3月下旬开始活动,5～6月危害最重,7月上、中旬成虫陆续羽化,产卵于叶背近缘及缺刻处.卵期10～14天;幼虫6龄,发育时转枝2～3次,历期310～320天;预蛹期4～6天;蛹期25～28天;雌虫寿命8～10天,雄虫6～8天.用敌杀死、快灭磷、敌敌畏的500倍液分别处理卵粒及初孵幼虫,敌杀死杀卵效果好,敌敌畏防幼虫较佳.
Paranthrene actinidiae Yang et Wang is a major pest endangering stems and shootsof Actinidia trees.The injury rate of adult trees was more than 95% in Lushan,JiangxiProvince in 1990.There were more than 30 heads in a seriously injured tree.In Lushan ithas one generation a year and overwinters as the second instar larvae in the bast(a few inthe medulla)of the branches in late November.Overwintering larvae resume feeding in lateMarch of the following year and reach the injury peak from May to June.There are sixlarval instars,and they shift 2～3 times from the branchlets to larger stems and trunks,tak-ing about 310～320 days.At maturity they begin to pupate in their tunnels in mid-June.The pre-pupal stage is about 4～6 days and the pupal period lasts 25～28 days.Adults be-gin to emerge in early to mid-July and oviposit after 2～3 days.The eggs are laid singly onthe underside of the leaves,taking 10～14 days to hatch.The female moths can live for 8～10 days,the male for 6～8 days.The proprotion of female to male is about 1:1.Insecticide experments have showed that it is very effective to spray the eggs with deltamethrin and to treat the newly hatched larvae with dichlorvos.
