Anagyrus 属的成员是粉蚧的主要内寄生物，因此包括粉蚧害虫的潜在重要生物防治剂。我们之前已经发现，粉蚧信息素的类似化合物环薰衣草酸丁酸酯 (CLB) 强烈吸引 Anagyrus sasadai Ishii，并且可以增强这种黄蜂在 CLB 处理的果园中的觅食活动。在本研究中，我们发现两组颜色不同的 Anagyrus 寄生蜂被 CLB 所吸引。一种是 A. satadai，另一种在形态学上被鉴定为 A. subalbipes Ishii，它被认为是 A. satadai 的同义词。我们怀疑Anagyrus的这两种颜色种群一定是独立的物种，因为它们在野外出现的模式不同。我们的形态学和分子分析支持了这个想法。我们确认了形态学诊断特征以区分这两个物种。此外，基于 COI 序列的分子系统发育分析显示 A. satadai 和 A. subalbipes 位于完全不同的簇中。这些发现不仅为Anagyrus spp 的分类学和系统发育提供了新的见解。但也为利用这些本土天敌对农业领域的粉蚧进行生物防治提供了重要知识。

Genetic and morphological approach to reappraising species validity in two different Anagyrus wasps (Hymenoptera: Encyrtidae) attracted by cyclolavandulyl butyrate

Members of the genus Anagyrus are primary endoparasitoids of mealybugs and thus include potentially important biological control agents of mealybug pests. We have previously discovered that an analogous compound of a mealybug pheromone, cyclolavandulyl butyrate (CLB), strongly attracts Anagyrus sawadai Ishii and can enhance the foraging activity of this wasp in CLB‐treated orchards. In the present study, we found two groups of Anagyrus parasitoids that differed in color were attracted to CLB. One was A. sawadai and the other type was morphologically identified as A. subalbipes Ishii, which had been considered to be synonymous with A. sawadai. We suspected these two color populations of Anagyrus must be independent species because of their different emergence patterns in the field. Our morphological and molecular analyses supported this idea. We confirmed morphologically diagnostic features to distinguish the two species. Furthermore, molecular phylogenetic analysis based on COI sequences revealed that A. sawadai and A. subalbipes were placed in entirely different clusters. These findings not only offered new insight into the taxonomy and phylogeny of Anagyrus spp. but also provided critical knowledge for the use of these indigenous natural enemies for biological control of mealybugs in agricultural fields.
