Resumo: The rice stink bug Oebalus poecilus (Dallas, 1851) occurs in every rice producing regions of Brazil, being even more common in plantations stabilished in rice they feed theirselvers on rachis and on spikelets that are on formation, causing a big qualitative and quantitative damage, being, that way, one of the main pest of the rice fields. The goal of this task was to avaliate, in vegetation houses, the hostes caused by one or two ground stink bug by little spikelets, in 13 genotipes of irrigated rice, trough the emergency of plants after 6, 9, 13 and 16 days of their plantation. Among all genotipes it was observed a reduction of 11.2 % of the emegency plant when infested with one rice stink bug and of 19.5 % with two stink bug. The biggest reductions of the emergency were observed on the genotipes CNA 8598 and CNA 8622, while the CNA 7830 was the most resistent supported by the results it can be concluded that it is possibile to select more resistent genotipes of rice to the O. poecilus.

O percevejo das panículas do arroz, Oebalus poecilus (Dallas 1851) (Heteroptera- Pentatomidae), ocorre em todas as regiões produtoras de arroz do Brasil, sendo mais comum nas lavouras estabelecidas em várzeas, alimentado-se da ráquis e das espiguetas em formação, causando grandes perdas quantitativas e qualitativas tornando-se, assim, numa das principais pragas dos arrozais. O objetivo do trabalho foi avaliar, em casa de vegetação, as perdas causadas por um ou dois percevejos adultos por espiguetas, em 13 genótipos de arroz irrigado, através da emergência de plântulas aos 6, 9, 13 e 16 dias após a semeadura. Entre todos os genótipos foi observada uma redução de 11,2% de emergência de plântulas quando infestados com um percevejo e de 19,5 % com dois percevejos. As maiores reduções de emergência foram observadas nos genótipos CNA 8598 e CNA 8622, enquanto que o CNA 7830 foi o mais resistente. Pelos resultados concluiu-se que é possível selecionar genótipos de arroz mais resistentes ao O. Pecilus.
