Egg Parasitoids of Stink Bugs (Hemiptera: Coreidae and Pentatomidae) on Soybean and Cowpea in Brazil

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.Se registraron los parasitoides que atacan los huevos de los chinches (Hemiptera: Coreidae y Pentatomidae) de forma natural y las interacciones con sus hospederos sobre las plantas hospederas soja (Glycine max [L.] Merrill; Fabales: Fabaceae) y caupí (Vigna unguiculata [L.] Walp .; Fabales: Fabaceae) en Brasil. Se observaron masas de huevos de chinches recolectados sobre las estructuras vegetales todos los días hasta la emergencia de los parasitoides o chinches. Los chinches fueron parasitados por 8 especies de parasitoides de huevos: 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) y Anastatus sp.

Diversity of Hemiptera Auchenorrhyncha in citrus, coffee and a fragment of native forest of the State of São Paulo

A população de Hemiptera Auchenorrhyncha foi estudada em pomares de laranja doce (Citrus sinensis), cafezais (Coffea arabica) e floresta estacional semidecidual com fisionomia arbustiva, em Bebedouro (SP), com o objetivo de avaliar a influencia do ecossistema natural na composição de espécies do agroecossistemas. O monitoramento foi feito com cartões adesivos amarelos, os quais foram trocados a cada 15 dias, efetuando-se a contagem e identificação dos Auchenorrhyncha coletados. Capturou-se o total de sete famílias, 11 subfamílias e 98 espécies, sendo Cicadellidae o grupo mais abundante. A floresta nativa apresentou a maior riqueza, diversidade e equitabilidade de espécies de Auchenorrhyncha, demonstrando ser mais estável que os demais habitats. Os altos valores de similaridades obtidos entre os agroecossistemas e a floresta demonstram que grande parte das espécies de cigarrinhas que está ocorrendo nos habitats agrícolas também está ocorrendo na floresta, indicando que esta pode estar funcionando como reservatório de espécies. A abundância de grupos taxonômicos de Auchenorrhyncha coletados variou nos habitats avaliados, sendo Proconiini o mais abundante no cafezal próximo à floresta, Athysanini, Scaphytopiini, Neocoelidiinae e Coelidiinae no pomar de laranja e cafezal distante da floresta; Cicadellinae e Agalliinae não se relacionaram a nenhum dos habitats. A presença de insetos vetores e possíveis vetores de doenças de plantas cultivadas nos habitats avaliados indicam a necessidade da implantação do manejo de pragas nessa área.The population of Hemiptera Auchenorrhyncha was studied in sweet citrus groves (Citrus sinensis), coffee plantations (Coffea arabica) and a semi-deciduous seasonal forest with shrub physiognomy in Bebedouro, SP, to evaluate the influence of the natural ecosystem on the species composition of the agroecosystems. Monitoring was carried out by using yellow stick cards, which were replaced every 15 days and all Auchenorrhyncha collected were counted and identified. Seven families, 11 subfamilies and 98 species were collected, with Cicadellidae being the most abundant. The native forest presented larger wealth, diversity and equitability of Auchenorrhyncha species, demonstrating to be more stable than the other habitats. The high values of similarities obtained between the agroecosystems and the forest demonstrated that great part of Auchenorrhyncha species occurring in the agricultural habitats was also occurring at the forest, indicating that the last may serve as reservoir of species. The abundance of the taxonomic groups of Auchenorrhyncha collected varied with the evaluated habitats, with Proconiini being the most abundant in the coffee plantation next to the forest, Athysanini, Scaphytopiini, Neocoelidiinae and Coelidiinae in the orange orchard and coffee plantation distant from the forest; Cicadellinae and Agalliinae were not related to any of the habitats. The presence of vector insects and possible vectors of plant diseases in the appraised habitats indicate the need of the implementation of strategies for landscape management.Fundo de Defesa da Citricultura (FUNDECITRUS
