摘　　要：舞毒蛾Lymantria dispar是世界性害虫,食性杂、为害严重,2019年首次在浙江杭州地区发现舞毒蛾为害。为了解舞毒蛾在该地区的为害情况,2020—2021年,对杭州地区舞毒蛾的发生为害特点、生物学特性和主要天敌情况进行了调查和研究。结果表明,舞毒蛾新发生区目前主要集中在杭州市西湖区、富阳区、余杭区三县交界处山林,主要取食为害麻栎Quercus acutissima等阔叶植物,种群密度较高;舞毒蛾在杭州地区1年发生1代,于3月下旬开始孵化,4月下旬—5月下旬化蛹,5月上旬—6月上旬羽化,以卵越冬,可以取食和为害多种南方重要生态树种和经济树种;毒蛾绒茧蜂Glyptapanteles liparidis、拟庸赘寄蝇Drino inconspicua和舞毒蛾质型多角体病毒LdMNPV为舞毒蛾在该地区的3种重要天敌生物,对舞毒蛾幼虫的感染或寄生率分别为36.54%、40.38%和58.93%。以上研究成果可以为舞毒蛾在杭州新发生区的科学监测和防控提供依据。In 2019,damage by Lymantria dispar was first found in Hangzhou,Zhejiang province.During 2020 and 2021,investigations were carried out on the characteristics of occurrence and damage,biological properties and natural enemies.The result showed that L.dispar occurred in the forest at the junction of Xihu,Fuyang and Yuhang district in Hangzhou,feeding on broad-leaved plants such as Quercus acutissima with high population density.It has one generation a year,hatches in late March,pupates from late April to late May,emerges from early May to early June,and overwinters by eggs.It damages many important ecological and economic tree species in Zhejiang.Glyptapanteles liparidis,Drino inconspicua and L.dispar Multiple-embedded Nucleopolyhedrovirus(LdMNPV)were three important natural enemies in this area,with parasitism or infection rate of 36.54%,40.38%and 58.93%.
