Egg parasitism of Tibraca limbativentris Stål (Hemiptera: Pentatomidae) in irrigated rice crops, Eldorado do Sul, RS. Arq. Inst. Biol. [online]. 2013, vol.80, n.4, pp.453-456.

The rice stem stink bug, Tibraca limbativentris Stål (Hemiptera: Pentatomidae), is an important pest of rice in Brazil. This study aimed to register egg parasitoids of T. limbativentris in irrigated rice crop in Eldorado do Sul (state of Rio Grande do Sul, Brazil). The area (603 m2) was inspected weekly from 01/21/2010 to 03/03/2010 and rice stem stink bug eggs were collected. It was observed only the occurrence of Telenomus podisi (Ashmead) (Hymenoptera: Platygastridae) as egg parasitoid and the parasitism rate was 75%. This is the first record of T. podisi in rice stem stink bug eggs collected in rice fields in the state of Rio Grande do Sul.

Keywords : Oryza sativa; rice stem stink bug; biological control; parasitoid; Telenomus podisi.
