Parasitoids of three mealybug pests (Hemiptera: Pseudococcidae), Planococcus ficus (Signoret), Pseudococcus sociabilis Hambleton, and Pseudococcus viburni (Signoret) have been identified for the first time in Brazil. Mealybugs were collected in fruit-growing areas along southern Brazil during 2013–2016. An integrative approach, combining morphological and molecular methods, was used to identify the Brazilian parasitoids to the species level. Fifteen species were recorded, including 14 primary parasitoids belonging to Encyrtidae and Platygastridae and a single secondary parasitoid species belonging to Signiphoridae. The encyrtid parasitoids Acerophagus flavidulus (Brèthes), Anagyrus calyxtoi Noyes and Zaplatycerus sp., and the signiphorid secondary parasitoid Chartocerus axillaris De Santis are reported for the first time in Brazil.

巴西首次发现了三种粉蚧害虫（半翅目：假球菌科）、无花果浮球藻（Signoret）、Pseudococcus sociabilis Hambleton 和Pseudococcus viburni（Signoret）的寄生蜂。2013-2016 年在巴西南部的水果种植区收集了粉蚧。一种结合形态学和分子方法的综合方法被用来在物种水平上识别巴西寄生蜂。共记录了 15 种，包括 14 种属于球虫科和侧扁虫科的初级寄生蜂，以及 1 种属于足虫科的次级寄生蜂。包膜寄生蜂Acerophagus flavidulus (Brèthes)、Anagyrus calyxtoi Noyes 和Zaplatycerus sp. 和 signiphorid 次生寄生蜂Chartocerus axillaris De Santis 在巴西首次被报道。
