Numerous gut microbes are associated with insects, but their composition remains largely unknown for many insect groups, along with factors influencing their composition. Here, we compared gut bacterial microbiota of two co-occurring agricultural pests, the peach fruit moth (PFM), , and the oriental fruit moth (OFM), , collected from different orchards and host plant species. Gut microbiota of both species was mainly composed of bacteria from Proteobacteria, followed by Firmicutes. The two species shared bacteria from the genera , , , and . When we compared two pairs of PFM and OFM populations collected from the same host species and the same orchard, there is no difference in alpha and beta diversity in gut microbiota. When we compared gut microbiota of the same species and host plant from different orchards, alpha and beta diversity was different in populations of PFM collected from two pear orchards but not in other comparisons. Our study suggests that the two pests share many features of gut microbiota and environment in orchards is a main factor influencing their gut microbiota.
许多肠道微生物与昆虫有关，但对于许多昆虫群体来说，它们的组成以及影响其组成的因素在很大程度上仍然未知。在这里，我们比较了两种同时出现的农业害虫——桃蛀螟（PFM）和梨小食心虫（OFM）——从不同果园和寄主植物物种采集的肠道细菌微生物群。两种害虫的肠道微生物群主要由变形菌门的细菌组成，其次是厚壁菌门。这两个物种共有来自 、 、 和 属的细菌。当我们比较从同一寄主物种和同一果园采集的两对桃蛀螟和梨小食心虫种群时，肠道微生物群的α和β多样性没有差异。当我们比较来自不同果园的同一物种和寄主植物的肠道微生物群时，从两个梨园采集的桃蛀螟种群的α和β多样性不同，但在其他比较中没有差异。我们的研究表明，这两种害虫共享许多肠道微生物群特征，果园环境是影响它们肠道微生物群的主要因素。
