摘要
近年来,在我国桉树上发生了一种严重的外来入侵害虫——桉树叶瘿球角姬小蜂Ophelimus maskelli(Ashmead)(膜翅目:姬小蜂科Eulophidae),其在桉树叶片上形成密密麻麻的小疱状虫瘿,造成桉树叶片大量脱落。为了利用天敌对该害虫进行生物防治,我们开展了该害虫的天敌调查。通过采集受害桉树叶片进行饲养,获得了一种寄生该害虫的寄生蜂——桉树扁角金绿姬小蜂Closterocerus chamaeleon(Girault)(膜翅目:姬小蜂科Eulophidae)。该寄生蜂为我国新纪录种,本文对其形态特征进行了详细描述,并提供了成虫鉴别特征的彩色照片。桉树扁角金绿姬小蜂原产地是澳大利亚,现在已被引进到世界上许多桉树栽培的国家和地区防治桉树叶瘿球角姬小蜂,防效十分显著。桉树扁角金绿姬小蜂是自然控制该害虫的优势天敌,我国现在发现了这种天敌,将在我国生物防治这种桉树外来入侵害虫上发挥重要作用。
s:A serious invasive pest,Ophelimus maskelli(Ashmead)(Hymenoptera:Eulophidae),occurred in China in recent years.The pest forms many small galls on the leaves of Eucalyptus trees and caused defoliation.For biological control of the pest,investigation of its natural enemy was carried out.An effective parasitoid species,Closterocerus chamaeleon(Girault)(Hymenoptera:Eulophidae),was discovered by rearing the Eucalyptus leaves with galls.It is the first record of the parasitoid in China and thus was morphologically described in detail in the present paper with color photos provided.Meanwhile,the diagnostic characters that distinguish the new parasitoid from other close species in the genus were provided.The parasitoid species originally distributes in Australia and now has invaded into many countries in the world where the trees are cultivated,where the parasitoid is a superior natural enemy for the gall maker pest.Therefore,the parasitoid species could play an important role in managing the pest in China.
