Abstract

ALVAREZ-RAMON, Óscar Iván et al. Diversity and annual fluctuation of cerambicids (Coleoptera: Cerambycidae) in a tropical forest of southeast Mexico. Acta biol.Colomb. [online]. 2022, vol.27, n.1, pp.79-87.  Epub Feb 15, 2022. ISSN 0120-548X.  https://doi.org/10.15446/abc.v27n1.89421.

The diversity and annual fluctuation of cerambicids associated with the rain forest edge and interior was estimated. The capture of insects was performed with interception traps baited with ethyl alcohol and ultraviolet light traps used as attractants. 295 specimens from three subfamilies, belonging to 56 species of 38 genera were collected. Lamiinae was the richest subfamily, with 40 species distributed in 20 genera, for Cerambycinae 14 species from 12 genera were collected and for Parandrinae two species of one genus. The most abundant genus was Leptostylus with eight species. Six species were identified as new records for Mexico and 29 for Tabasco. In the forest edge, 155 specimens from two subfamilies, belonging to 37 species from 26 genera, were collected. In the forest interior 140 specimens were collected from three subfamilies, belonging to 36 species from 26 genera. It was determined that the communities have 17 shared species. The maximum value of true diversity was obtained in the forest edge with 15.96 and the minimum value in the forest interior with 12.69. The values of A, A * and A+ were determined and implied a low phylogenetic separation between the cerambycid species in both communities. The temporal fluctuation of the Cerambycidae community presented the maximum values abundance in February, May and August, months where there is a reduction in the precipitation. Finally, the species accumulation curve does not present an asymptote, so new records may increase.
