Abstract

GERONIMO-TORRES, José del Carmen et al. Diversity and vertical distribution of borers beetles (Coleoptera: Bostrichidae, Curculionidae: Scolytinae, Platypodinae) in a mangrove in Tabasco, Mexico. Caldasia [online]. 2021, vol.43, n.1, pp.172-185.  Epub Mar 24, 2021. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v43n1.84499.

Diversity, and for the first time, the vertical distribution of borer insects (Scolytinae, Platypodinae, and Bostrichidae) are described as associated with the edge and inside of a mangrove. To determine the diversity in these sites, insects were captured with interception traps baited with 70 % ethyl alcohol and using ultraviolet light as an attractant. To analyze the vertical distribution, traps baited with ethyl alcohol were placed at 1.5 m, 6 m, and 12 m in height. According to the diversity index CD), the border was 1.36 more diverse than the inside with 15.82 and 11.67 respectively. The traps used at 6 m captured the greatest diversity both at the edge and inside, although the 1.5m traps captured the greatest abundance. At the edge, ten of the twelve months presented statistically significant differences in their abundance and for the inside, these differences were presented in eight of the twelve months. Regarding diversity (1D), at the edge, these statistical differences occur in April, May, July, and august, while in the inside in June, November, and December. The differences described may be related to the variability in the environmental conditions of the mangrove, which produces changes in the structure and composition of the insect communities.
