Conteúdo: | Tritrophic interactions mediated by semiochemicals have been intensively studied from the view-point of ecological relationships with Nearctic tritrophic organisms. However, there are few studies involving interactions with different herbivores on the same host plant in Neotropical systems. The objective of the current study was to investigate the effects of herbivory by two species of stink bugs (Heteroptera: Pentatomidae) with the same feeding habit ? Tibraca limbativentris Stal and Glyphepomis spinosa Campos & Grazia?on indirect and direct defence strategies of rice plants. The responsesof each stink bug species (virgin and mated females) and of their main natural enemy, the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Platygastridae; mated females), to volatiles from undamaged and herbivore-damaged rice plants were evaluated using a Y-tube olfactometer. The results showed that rice plants responded differently to T. limbativentris or G. spinosa herbivory,enhancing the production of a different blend of volatile compounds, which reduced the attraction for conspecific stink bugs and elicited the foraging behaviour of T. podisi.
