Crisomélidos1 Asociados a Vegetación Arvense y Ruderal del Desierto Chihuahuense Mexicano

Abstract

The abundance and richness of adults of the Chrysomelidae family, associated with weeds and ruderal vegetation in Chihuahua, Durango, and Coahuila, states part of the Mexican Chihuahuan Desert, were studied. Adults (794) belonging to six subfamilies, nine tribes, 36 genera, and 59 species were collected. The subfamily with the greatest richness and abundance was Galerucinae with 24 species and 570 individuals (71.7%). The most abundant species was Diabrotica balteata (LeConte 1865) with 157 individuals, followed by Colaspis hesperia (Blake 1974) with 91 individuals. The dominance of the communities did not significantly vary between the studied sites. The importance of weedy and ruderal vegetation is highlighted as sites that maintain important levels of species richness in arid environments.
