Abstract

Parasitoids naturally attacking stink bug (Hemiptera: Coreidae and Pentatomidae) eggs and interactions with their hosts were recorded on soybean (Glycine max [L.] Merril; Fabales: Fabaceae) and cowpea (Vigna unguiculata [L.] Walp.; Fabales: Fabaceae) host plants in Brazil. Egg masses of stink bugs collected from plant structures were observed daily until emergence of either parasitoids or bugs. Stink bugs were parasitized by 8 species of egg parasitoids: Trissolcus urichi Crawford, Trissolcus teretis Johnson, Trissolcus bodkini Crawford, Telenomus podisi Ashmead, Phanuropsis semiflaviventris Girault (Hymenoptera: Platygastridae), Neorileya flavipes Ashmead (Hymenoptera: Eurytomidae), Ooencyrtus anasae (Ashmead) (Hymenoptera: Encyrtidae), and Anastatus sp. (Hymenoptera: Eupelmidae). Trissolcus urichi, Te. podisi, O. anasae, and N. flavipes parasitized eggs of 2 or more species of stink bugs, and Tr. urichi and Te. podisi were the most generalist. Phanuropsis semiflaviventris, Tr. teretis, Tr. bodkini, and Anastatus sp. showed specialist behavior, because each of them parasitized only 1 species of stink bug.2015Autoria: QUERINO [i.e. SILVA], R.
