Contribuição para o conhecimento de alguns hemípteros que atacam as plantas cítricas

Resumo

Contribution to the knowledge of some Citrus damaging Hemiptera. This paper deals with field and laboratory investigations on Crinocerus sancius (Fabr., 1775), Leptoglossus gonagra (Fabr., 1775), and. L. stigma (Herb., 1784), all belonging to the family Coreidae, Order Hemiptera. These three species are noxious to several fruits, including citrus. The two Leptoglossus and the damages they cause on oranges have been investigated by several writers in the last 25 years. On the other hand, c. sancius was discovered damaging Citrus only in 1959, increasing in importance since its discovery. Redescription of the adults, bionomical notes, hosts, and so on, are the main purpose of this study.
