Abstract
Aquatic Coleoptera, Hemiptera, and Odonata associated with Anopheles albimanus Wiedemann larval habitats (defined by dominant plant vegetation) were investigated in various hydrological types along the coastal plain of southern Chiapas, Mexico. Aquatic insects were sampled by manual dragging nets, and mosquito larvae were sampled with standard dippers. Aquatic Coleoptera were the most abundant and diverse group, represented by 20 genera, followed by Hemiptera and Odonata, each with 16 genera. Aquatic insects were more abundant in permanent and temporary lagoons in Hymenachne amplexicaulis (Rudge) Nees and Lippia nodosa (L.) Michx. habitats, whereas mosquito larvae were most abundant in Ceratophyllum demersum L. and Crinum erubescens Soland. habitats, where aquatic insects were moderately abundant. Significant association in regression models with the addition of quadratic terms were found in aquatic Coleoptera and Odonata with respect to mosquito larvae. However, adjusted models that included environmental parameters proved these associations to be nonsignificant.
