Vitellogenin receptor (VgR) is essential to vitellogenin uptaking and dominates ovary maturation in insects. However, the function of VgR in parasitoid wasps is largely unknown. Here, we applied the parasitoid as a study model to investigate the function of VgR in parasitoids. Despite the conserved sequence characteristics with other insect VgRs, we found VgR () gene was highly expressed in head but lower in ovary. In addition, we found that LbVgR had no effects on ovary development, but participated in host-searching behavior of female and mating behavior of male . Comparative transcriptome analysis further revealed LbVgR might play crucial roles in regulating the expression of some important chemoreception genes to adjust the parasitoid behaviors. These results will broaden our knowledge of the function of VgR in insects, and contribute to develop advanced pest management strategies using parasitoids as biocontrol agents.
卵黄原蛋白受体（VgR）对于卵黄原蛋白的摄取至关重要，并且在昆虫卵巢成熟过程中起主导作用。然而，VgR在寄生蜂中的功能在很大程度上尚不清楚。在此，我们以寄生蜂作为研究模型来探究VgR在寄生蜂中的功能。尽管与其他昆虫的VgR具有保守的序列特征，但我们发现VgR（）基因在头部高表达而在卵巢中低表达。此外，我们发现LbVgR对卵巢发育没有影响，但参与了雌蜂的寄主搜索行为和雄蜂的交配行为。比较转录组分析进一步揭示，LbVgR可能在调节一些重要的化学感受基因的表达以调整寄生蜂行为方面发挥关键作用。这些结果将拓宽我们对VgR在昆虫中功能的认识，并有助于开发以寄生蜂作为生物防治剂的先进害虫管理策略。
