含笑尾小卷蛾生物学特性及其发生规律的研究

含笑尾小卷蛾SorolophamicheliacolaLiu是木兰科（Magnoliaceae）含笑属（Michelia）植物叶部的主要害虫，在福建省南平市一年发生6代，以蛹越冬有明显世代重叠现象．翌年3月上、中旬越冬蛹羽化为成虫，并上树补充营养，交配产卵．卵散生在嫩叶表面经3～5天孵化为幼虫，幼虫期18～32天；蛹期15～22天；越冬蛹42～60天；成虫寿命5～7天．主要天敌有绒茧蜂（APantelessp）、姬小蜂科（Eu－loPhidae）中的3～4种，以及陆马蜂（PolistesrothneyigrhamiVanderVecht）广腰螳螂（HierodulapatelliferaServiue）等．该虫的发生、生长猖獗成灾，与温度、湿度、纬度、海拨高度、林分结构与组成、地被物以及天敌等环境因子均有密切关系．

Study on the Bionomics and Occurrence Regular of Sorolopha micheliacola Liu

Sorolopha micheliacola Liu is the main insect eat the leaves of Michelia of Magnoliaceae, whichcan reproduct six generations every year and pass through winter as pupae in Nanping, Fujian,with an evidentoverlap phenomenon of life-history. The pupae emerge as adult and fly to the trees to take food and matethere from the first ten-day period to the middle ten-day period of March in the next year. The eggs are laidon the surface of the tender leaves dispersedly, and begin to hatch after 3~5 days. The larvae stage lastsabout 18~32 days, the pupal stage lasts about 15~22 days, the overwintering pupal stage lasts about 42~60 days, and the adult life-span is about 5~7 days.
