In this work, we report for the first time the occurrence of the parasitoid wasp Brachymeria amenocles (Walker, 1846) (Hymenoptera: Chalcididae) associated with the larvae of the flesh fly, Peckia (Peckia) chrysostoma (Wiedemann, 1830) (Diptera: Sarcophagidae), in Brazil. This parasitoid species was collected together with the species Brachymeria podagrica (Fabricius, 1787), in the municipality of Rio de Janeiro, geographically located in the Southeast region of Brazil, in larvae of the same host species reared in the same attraction substrate, behaving as solitary parasitoids. A trap containing putrefying sardine was exposed for 48 h, in the upper part of a house, located in Vila Isabel, an urban area. The larvae collected were reared in the laboratory without control of environmental conditions. A total of three adult parasitoid wasps of the species B. podagrica, and nine adult parasitoid wasps of the species B. amenocles emerged from 12 host pupae, resulting in a prevalence of parasitoidism of 4.8% and 14.5%, respectively. Developing parasitoids at the pupal phase were observed in another 34 host pupae dissected.
在这项工作中，我们首次报道了寄生蜂 Brachymeria amenocles（Walker，1846）（膜翅目：Chalcididae）与肉蝇幼虫 Peckia（Peckia）chrysostoma（Wiedemann，1830）（双翅目：Sarcophagidae）相关联的情况。这种寄生蜂与 Brachymeria podagrica（Fabricius，1787）一起在巴西东南部的里约热内卢市被收集，在相同的诱捕基质中饲养的同一宿主幼虫中发现了这两种寄生蜂，它们表现为独居寄生蜂。一个装有腐臭沙丁鱼的诱捕器暴露在一栋房子的上层 48 小时，位于 Vila Isabel 的城市地区。收集到的幼虫在没有环境条件控制的情况下在实验室中饲养。从 12 个宿主蛹中总共出现了 3 只成年寄生蜂 B. podagrica 和 9 只成年寄生蜂 B. amenocles，寄生率分别为 4.8%和 14.5%。在解剖的另外 34 个宿主蛹中观察到处于蛹期的发育中的寄生蜂。
