Seasonal abundance and mortality of Oebalus poecilus (Dallas) (Hemiptera: Pentatomidae) in a hibernation refuge.
Oebalus poecilus (Dallas) is an important pest affecting irrigated rice in Rio Grande do Sul, Brazil. It hibernates during the coldest months of the year in refuges such as bamboo litter. This study examined O. poecilus hibernation to determine the causes of mortality during this period. The study was conducted in a 140 m(2) bamboo plantation located in a rice-growing area in Eldorado do Sul Co...
متن کاملMorphological patterns of the heteropycnotic chromatin and nucleolar material in meiosis and spermiogenesis of some Pentatomidae (Heteroptera)
Pentatomidae is a family of Heteroptera which includes several agriculture pests that have had different aspects of their meiosis and spermiogenesis analyzed. In the present study we analyzed the morphological patterns of the heteropycnotic chromatin and the nucleolar material of Mormidea v-luteum, Oebalus poecilus and Oebalus ypsilongriseus. The three species presented multilobate testes, with...
متن کاملParaedessa, a new genus of Edessinae (Hemiptera: Heteroptera: Pentatomidae).

The species are very similar and their identification is possible only by comparing genitalia. New combinations proposed are ...
متن کاملThestral incognitus, a new genus and species of Pentatomidae from Chile (Heteroptera: Pentatomidae: Pentatominae: Carpocorini).
Thestral incognitus, new genus and species of Pentatomidae (Pentatominae: Carpocorini) is described from central Chile. The relationships among this new genus and other South American genera are discussed. Also, similarities are noted between Thestral and the Australian genus Poecilotoma.

متن کاملFactors influencing mate choice in Euschistus conspersus Uhler (Heteroptera: Pentatomidae).
The patterns of mating and possible factors influencing mate choice in the consperse stink bug, Euschistus conspersus Uhler, were studied in a series of laboratory experiments. Males were found to transfer a significant percentage of their body mass during the initial mating. Mating was also found to reduce male longevity by 37.8% but had no significant effect on female longevity or fecundity. ...
