Abstract

Ostrinia scapulalis (Walker) (Lepidoptera: Crambidae), the adzuki bean borer, is a serious pest in adzuki bean plants and other dicotyledons. Wolbachia, the insect symbiont that infects O. scapulalis, causes male-killing during the embryonic and larval stages in the insect host. Previous studies have reported an association between Wolbachia density dynamics and the sex phenotype of offspring. In this study, we treated O. scapulalis at the adult and larval stages using 3O-C12-HSL as a quorum sensing (QS) inducer and 4-phenylbutanol as a QS inhibitor. QS inducer treatment in the adult stage increased the density of Wolbachia in O. scapulalis, and there was a strong positive correlation between Wolbachia density and female proportion in the adult stage after QS inhibitor treatment. QS inducer and inhibitor treatments in the larval stage stabilize Wolbachia density in O. scapulalis.

群体感应诱导剂和抑制剂对小豆螟内共生体沃尔巴克氏体灭雄的影响

小豆螟虫是小豆及其他双子叶植物的严重害虫。沃尔巴克氏体(Wolbachia)是感染肩胛骨棘球蚴的昆虫共生体，在昆虫宿主的胚胎和幼虫阶段导致雄性死亡。以前的研究已经报道了沃尔巴克氏体密度动态和后代性别表型之间的关联。本研究以30 - c12 - hsl为群体感应诱导剂，4-苯基丁醇为群体感应抑制剂，分别对肩周虫成虫和幼虫进行处理。成虫期QS诱诱剂处理增加了肩胛骨棘毛线虫的沃尔巴克氏体密度，且QS抑制剂处理后肩胛骨棘毛线虫成虫期沃尔巴克氏体密度与雌蜂比例呈较强的正相关。幼虫期QS诱导剂和抑制剂处理稳定了肩胛骨棘球蚴的沃尔巴克氏体密度。
