竹弯茎野螟的3种新记录寄生蜂

Three newly recorded parasitoid species of Crypsiptya coclesalis(Walker)

2013年5月至2014年10月,对竹林害虫竹弯茎野螟[Crypsiptya coclesalis(Walker)]的寄生蜂及寄生率进行调查,共发现7种寄生蜂。其中3种是首次记录寄生在该种害虫的寄生蜂,即:日本棱角肿腿蜂(Goniozus japonicus Ashmead)、兰氏原绒茧蜂(Protapanteles lamborni Wilkinson)和螟黄赤眼蜂(Trichogramma chilonis Ishii)。对不同寄生蜂的寄生率调查结果表明,兰氏原绒茧蜂的寄生率最高,为45.2%,对竹弯茎野螟具有较好控制作用。同时,本文首次报道寄生于竹弯茎野螟3种寄生蜂的主要鉴别特征及其寄生生物学,并提供了形态特征图。

An investigation on hymenopterous parasitoids of Crypsiptya coclesalis（Walker）was carried out from May,2013 to October,2014.The results showed that 7species of parasitic wasps were found.Among them,three species of parasitic wasps,namely,Goniozus japonicus,Protapanteles lamborni and Trichogramma chilonis,were newly recorded to attack C.coclesalis.The parasitic rate results showed that the control function of P.lamborni was the largest on the population number of C.coclesalis,with the parasitism rate of 45.2%.Meanwhile,the morphological character and parasitic biology were briefly described in this paper.
