Trissolcus teretis (Johnson, 1987) (Hymenoptera: Scelionidae) parasitism on Euschistus heros (Fabricius, 1798) and Diceraeus melacanthus Dallas, 1851 (Hemiptera: Pentatomidae) eggs at different temperatures

Trissolcus teretis has been recorded to parasitize eggs not only of Euschistus heros and Diceraeus melacanthus but also other stink bug species in the most important soybean producing countries South America such as Brazil, Argentina well Neotropical region. Despite several studies relating its natural incidence parasitism, impact different temperatures on biology parasitism capacity T. E. D. is practically unknown. Considering that biological traits can be highly influenced by temperature, research at hosts theoretical practical interest. We therefore evaluated development 15ºC, 20ºC, 25ºC, 30ºC. Temperature had an parasitoid reared both studied hosts. Although we extreme temperature these conditions are unfavorable for impairing traits, especially survival larvae adult parasitism. Therefore, application crop fields where 15ºC or lower common, additional necessary investigate possible need increase numbers during releases choose smaller intervals between multiple releases.
