A.  aDifferential induction of volatiles in rice plants by two stink bug species influence behaviour of conspecifics and their natural enemy Telenomus podisi.h[electronic resource]  c2020  aTritrophic 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.  aHymenoptera  aPentatomidae  aTritrophic interactions  aHeteroptera  aPraga de Planta  aTibraca Limbativentris  aEgg parasitoid  aGlyphepomis spinosa  aInsect behaviour  aPlant-insect interactions  aPlatygastridae1 aBARRIGOSSI, J.
