摘要
伊藤厚丝叶蜂Pachynematus itoi Okutani(Hymenoptera:Tenthredinidae)以幼虫为害落叶松松针,并在我国东北地区多次暴发成灾。生物防治伊藤厚丝叶蜂具有防治效果好、防治成本低和持效期长等优点,挖掘其卵寄生蜂有助于在卵期控制其种群数量,从而降低幼虫期对落叶松的为害。本研究于2018年7月及2019年8月在吉林长春采集到其卵寄生蜂阿拉托斯新釉姬小蜂Neochrysocharis aratus(Walker)(Hymenoptera:Eulophidae),共99头(52雌,47雄),这是该寄生蜂在我国的首次发现,也是其寄生伊藤厚丝叶蜂的首次报道。本研究对该寄生蜂的形态特征进行了详细描述,提供了成蜂彩色整体图及局部特征图,并介绍了该种的寄主和世界分布,可为后续生物防治伊藤厚丝叶蜂提供参考。
The larvae of Pachynematus itoi Okutani(Hymenoptera:Tenthredinidae)feed on pine needles of Larix spp.,causing outbreaks in northeast China.Biological control of P.itoi has the advantages of high control efficiency,low control cost and long persistence.Egg parasitoid wasps can help decrease pest population during the egg stage,thus reducing larval damage to larch.In July 2018 and August 2019,99 wasps(52 females and 47 males)of the egg parasitoid,Neochrysocharis aratus(Walker)(Hymenoptera:Eulophidae),were collected in Changchun,Jilin.This was the first discovery of the parasitoid wasp in China,and the first report of its parasitism against on P.itoi.This study provided a detailed description of its morphological features,with color pictures of overall view and local view of the adult wasps as well as an introduction to the hosts and world distribution of the wasp species.This study may help the biological control of P.itoi.
