RESUMO: O percevejo marrom, Euschistus heros (Hemiptera:Pentatomidae), é um inseto praga na cultura da soja no estado do Mato Grosso, Brasil. Nesta região, inseticidas sintéticos são frequentemente utilizados ao controle de insetos. Uma alternativa para o uso indiscriminado de inseticidas é o controle biológico com parasitoides. Assim, o objetivo deste estudo foi realizar o levantamento dos parasitoides que utilizam adultos de E. heros como hospedeiros. Para isso, amostras aleatórias foram conduzidas durante as safras de 2009/10 e 2010/11, em duas fazendas produtoras de soja (sistema convencional) em Tangará da Serra, Mato Grosso, Brasil. O número total de E. heros coletados foi: 297 (Área 1) e 293 (Área 2) em 2009/10 e 295 (Área 1) e 376 (Área 2) em 2010/11. Destes percevejos 1,50 (Área 1) e 13,99% (Área 2) encontravam-se parasitados em 2009/10 e 8,47 (Área 1) e 7,45% (Área 2) em 2010/11. Nas duas áreas, o parasitoide encontrado foi Hexacladia smithii Ashmead (Hymenoptera: Encyrtidae). Este é o primeiro registro de parasitismo em adultos de E. heros no estado do Mato Grosso, Brasil.

Occurrence of parasitoids in eggs of soybean lepidopteran pests, such as velvetbean caterpillar, soybean loopers and others the genus Spodoptera and Helicoverpa in Mato Grosso, Brazil was studied. Due to the scarcity of information on the natural occurrence of parasitoids in lepidopteran eggs in soybean fields in Mato Grosso surveys were conducted in Tangará da Serra to verify the occurrence these parasitoids. Surveys were conducted in two areas in Tangará da Serra, with a total of 591 eggs, of which 138 and 77 eggs were collected in area I and 274 and 102 eggs in area II, during the 2008/2009 and 2009/2010 soybean seasons, respectively. From the eggs collected in area I, 26.6% were parasitized in the first year and 30.0% in the second season. In area II, the parasitism rates were 40.2% and 27.5% for the first and second season respectively. The species of parasitoid collected was Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) totaling 354 parasitoids. We conclude that there is a natural occurrence of T. pretiosum, this being the species of egg parasitoid found, and that parasitism rates were higher when compared with other studies under natural conditions, especially considering the large number of chemical products used in the fields. The identification of the eggs parasitoids in Mato Grosso State is important to development of biological control programs for lepidopteran pests.

“…Durante o período, os percevejos tornaram-se pouco ativos e apresentaram máculas pretas no abdome, de onde vários indivíduos do parasitóide Hexacladia smithii (Ashmead) emergiram. Internamente, os órgãos localizados na cavidade abdominal foram danifi cados e o abdome apresentou-se totalmente vazio, assim como descrito para Euschistus heros (Fabricius) (Corrêa-Ferreira et al 1998). A identifi cação dos parasitóides somente foi confi rmada em 2008, pela Profa.…”
