ABSTRACT Since its arrival in New Zealand, Meteorus pulchricornis has parasitised adventive and native lepidopteran host species. We carried out a survey of parasitism by M. pulchricornis and native parasitoids of native lepidopteran host species in the Auckland region. From September 2013 to January 2016, parasitoids were reared from larvae collected from native host plants in habitats including urban gardens, regenerating native forest and native forest remnants. Meteorus pulchricornis was the most abundant parasitoid, accounting for 12% of parasitism, and was reared from 11 of 26 native Lepidoptera species. The host range of M. pulchricornis overlapped with eight other parasitoid species. A previously unrecorded species of Casinaria as well as M. pulchricornis were reared from Cleora scriptaria larvae collected from Te Hauturu-ō-Toi/Little Barrier Island. The parasitoid host association data collected provides preliminary information on the potential impact of M. pulchricornis on native parasitoids.

对外来寄生蜂 Meteorus pulchricornis（膜翅目：茧蜂科）和本地鳞翅目幼虫寄生蜂的调查

摘要 自从抵达新西兰以来，Meteorus pulchricornis 已经寄生于外来和本地鳞翅目宿主物种。我们对奥克兰地区的本地鳞翅目宿主物种的 M. pulchricornis 和本地寄生蜂进行了寄生虫调查。2013 年 9 月至 2016 年 1 月，从城市花园、再生原生林和原生林残余等栖息地的原生寄主植物中收集的幼虫饲养拟寄生物。Meteorus pulchricornis 是最丰富的寄生虫，占寄生虫的 12%，由 26 种本地鳞翅目物种中的 11 种饲养。M. pulchricornis 的寄主范围与其他八种寄生蜂物种重叠。以前未记录的 Casinaria 以及 M. pulchricornis 是从从 Te Hauturu-ō-Toi/Little Barrier Island 收集的 Cleora scriptaria 幼虫饲养的。收集的寄生物寄主关联数据提供了关于 M. pulchricornis 对本地寄生物的潜在影响的初步信息。
