基　　金：江苏省林业有害生物普查项目(苏林检[2014]8号);中央财政林业科技推广项目“美国白蛾等重大林业害虫生物防治技术示范推广”(苏[2018]TG06);徐州市科技计划项目“美国白蛾核型多角体病毒增殖及应用技术研发”(KC18130)。

摘　　要：采用踏查和灯诱等方法,系统调查了徐州市林业害虫的捕食性天敌昆虫种类、寄主和分布等情况,并根据分布范围和成虫标本采集总数,将捕食性天敌种类划分为优势种类、常见种类和稀有种类。调查结果显示,徐州市共有捕食性天敌7目26科107种,对比历史上已有记载的7目15科49种,此次仅调查到26种,另新增记录58种。调查到的84种捕食性天敌(隶属于7目25科)中,在全市分布较广的常见种类达41种,其余43种为稀有种类,仅分布在1—2个县(市、区)。41种常见种类中,分布广且成虫标本数超过10枚的优势种类共14种,分别为半翅目的暴猎蝽、褐负蝽,鞘翅目的绿步甲、黄斑青步甲、中华婪步甲、黑缘红瓢虫、异色瓢虫、十二斑褐菌瓢虫,膜翅目的陆马蜂,双翅目的黑带食蚜蝇、中华食虫虻,蜻蜓目的黄蜻和脉翅目的中华草蛉及螳螂目的中华大刀螂等。该调查首次系统查明了徐州市捕食性天敌昆虫的种类,初步掌握了它们的寄主、分布和发生等资源现状,为开展美国白蛾和杨小舟蛾等重要林业害虫的本土捕食性天敌昆虫生物学特性和保护利用技术研究提供了科学依据。The species,hosts and distribution of predators preying forest insect pests in Xuzhou Prefecture were systematically investigated by personal inspection and light trap from 2015 to 2017,and these predators could be categorized into dominant species,common species and rare species according to the distribution range and the total number of adult specimens.Investigation results showed that 107 species of predators belonging to 26 families of 7 orders were found,including 49 species(belonging to 15 families of 7 orders,but 26 species only found in this investigation)recorded in historical investigations and 58 species newly found in Xuzhou City.Among 84 predator species(belonging to 25 families of 7 orders),41 common species distributed in 3 counties in Xuzhou Prefecture,and the others were rare species,which distributed in 1—2 counties.Fourteen dominant species,distributed widely with total number of adult specimens over 10 such as Agriosphodrus dohrni,Diplonychus rusticus(Hemiptera),Carabus smaragdinus,Chlaenius micans,Harpalus sinicus,Chilocorus rubidus,Harmonia axyridis,Vibidiaduodecimguttata(Coleoptera),Polistes rothneyi grahami(Hymenoptera),Episyrphus balteatus,Ommatius chinensis(Diptera),Pantala flavescens(Odonata),Chrysopa sinica(Neuroptera),and Tenodera sinensis(Mantodea).This survey systematically identified the species of predators in Xuzhou Prefecture,preliminarily fixed their host,distribution and occurrence,etc.,which will provide scientific foundation for studying on biological characteristics,protection and utilization of the native species preying such important pests as Hyphantria cunea and Micromelalopha troglodyta.
