摘要: 本文报道在内蒙古和北京发现的一个寄生蜂新种——元宝枫希姬小蜂Hyssopus truncatumi Yang,Liu et Cao(膜翅目:姬小蜂科Eulophidae)。该姬小蜂寄生杨凌冠麦蛾Bagdadia yanglingensis幼虫(为害元宝枫种子)和元宝枫花细蛾Caloptilia dentata幼虫(取食元宝枫叶片),对杨凌冠麦蛾幼虫的寄生率达34.4%。目前,杨凌冠麦蛾对元宝枫种子危害严重,种子受害率达40%,同时,元宝枫花细蛾也是元宝枫的重要食叶害虫,因此,利用元宝枫希姬小蜂开展这两种害虫的生物防治具有重要的应用潜力和价值。本文详细描述了元宝枫希姬小蜂的形态特征,并附彩色形态特征图;同时,与希姬小蜂属的两个近似种进行了鉴别特征比较。

Abstract: The present paper reported a new species of parasitic wasp, Hyssopus truncatumi Yang, Liu et Cao (Hymenoptera: Eulophidae), found in Inner Mongolia and Beijing. The eulophid wasp effectively parasitizes the larval stages of two major pests: Bagdadia yanglingensis (Lepidoptera: Gelechiidae), a seed-eating pest, and Caloptilia dentata (Lepidoptera: Gracilariidae), a defoliator, both of which infest Acer truncatum (Aceraceae), especially achieving a parasitism rate of 34.4% in B. yanglingensis larvae. Given that B. yanglingensis poses a severe threat to seeds of A. truncatum, with a seed damage rate up to 40%, and C. dentata has emerged as a prominent defoliating pest that significantly impacts the health of A. truncatum, the employment of Hyssopus truncatumi sp. nov. For holds significant value in biological control of these two detrimental pests possess immense potential and valuable prospects for practical application. This article provides a detailed morphological description of this new species, along with colored photos of the parasitic wasp. Meanwhile, a comparative analysis of the distinguishing features is conducted to distinguish this new species from two close related species within the genus Hyssopus.
