Resumen:
Insect-aroid interaction studies have focused largely on pollination
systems; however, few report trophic interactions with other herbivores.
This study features the endophagous insect community in reproductive
aroid structures of a tropical rainforest of Mexico, and the shifting
that occurs along an altitudinal gradient and among different hosts. In
three sites of the Los Tuxtlas Biosphere Reserve in Mexico, we surveyed
eight aroid species over a yearly cycle. The insects found were reared
in the laboratory, quantified and identified. Data were analyzed through
species interaction networks. We recorded 34 endophagous species from 21
families belonging to four insect orders. The community was highly
specialized at both network and species levels. Along the altitudinal
gradient, there was a reduction in richness and a high turnover of
species, while the assemblage among hosts was also highly specific, with
different dominant species. Our findings suggest that intrinsic plant
factors could influence their occupation, and that the coexistence of
distinct insect species in the assemblage could exert a direct or
indirect influence on their ability to colonize such resources.
