我国樟树害虫的4个新记录种

Four newly recorded pest species of Cinnamomum camphora in China

[目的]2015—2019年对福建省樟树害虫开展调查,以期为当地樟树虫害防控提供依据.[方法]结合野外调查、采集幼虫和室内饲养,获得成虫后进行种类鉴定.[结果]发现4种为害樟树的鳞翅目新害虫:樱花翅小卷蛾(Lobesia lithogonia Diakonoff)、迹银纹刺蛾(Miresa kwangtungensis Hering)、鹰三角尺蛾(Zanclopera falcata Warren)和埃尺蛾[Ectropis crepuscu-laria(Denis et Schiffermuller)],并对4种害虫的寄主、分布、形态特征及生物学特性等进行了简述.其中,樱花翅小卷蛾为福建省昆虫新记录种.[结论]樟树害虫种类丰富,4个取食樟树新记录种的发现对其害虫综合治理及昆虫多样性研究提供了参考.

[Purpose]A survey of pest species of Cinnamomum camphora was conducted in Fujian Province from 2015 to 2019 in order to provide basic information for local pest control.[Method]Field investigation,larva collection and laboratory breeding of C.camphor pests were carried out.Species were identified after obtaining the adults.[Result]Four lepidopteran pests feeding on C.camphora were discovered for the first time,including Lobesia lithogonia Diakonoff,Miresa kwangtungensis Hering,Zanclopera falcata Warren,and Ectropis crepuscularia(Denis et Schiffermuller).The hosts,distribution,morphological and biological characteris-tics of these insect pests were briefly described.Among these pests,L.lithogonia was a newly recorded species in Fujian Province.[Conclusion]There are many pest species of C.camphor.The discovery of the four newly recorded pest species of C.camphor provides a reference for the integrated pest management and insect diversity analysis of C.camphor.
