摘要

The bark and ambrosia beetle diversity in cocoa agroecosystems was studied during 2007 in Tabasco, Mexico. Adult insects were gathered in 4 localities with ethanol and light traps and by direct collecting in their host plants. 19 263 specimens were gathered, belonging to 51 species and 26 genera. Araptus hymenaeae and Cnesinus squamosus are new records for Mexico. The maximum diversity of insects captured with the 3 collecting methods was obtained in El Bajío (H′=2.45 and Dmg=4.83), the minimum in Río Seco (H′=2.29) and Km. 21 (Dmg=3.85), and the maximum value of justness (J) was obtained in El Bajío (0.67). The Sorensen similarity index (Is) showed that the study places present the same species composition. The diversity, justness and similarity indices, applied to the beetles captured with each method, showed differences except with the alcohol traps. The beetles present marked populational picks at the beginning and at the end of the year. The biggest number of Scolytinae species were gathered in the host Theobroma cocoa (16 species) and Swietenia macrophylla (13).
