Relative Abundance of Stink bugs (Hemiptera: Pentatomidae) in Southwestern Colombia Rice Fields

Abstract

Relative abundance of stink bugs was determined from 01 May 1989 to 30 September 1992 in 80 commercial rice fields in Colombia and in 12 selected rice-producing countries of Latin America. Fifteen stink bug species from nine genera were found in Colombia. The species are Oebalus ornatus (Sailer), Mormidea maculata Dallas, Tribraca obscurata Bergroth, M. pictiventris Stål, O. pugnax torridus (Sailer), Proxys punctulatus (Palisot de Beauvois), O. insularis (Stål), T. limbativentris Stål, and O. ypsilongriseus (De Greer). In Valle del Cauca Department in southwestern Colombia, the most abundant species was O. ornatus representing 94.1% of the stink bugs collected. Seven species comprised the remaining 5.9%. Oebalus ornatus and O. ypsilongriseus were recovered from seven Latin America countries and had the widest geographical range of the stink bugs species collected during the study.
