Resumen

GARCIA, Mauricio  y  JIMENEZ-RAMOS,, Erickxander. Record of aquatic insects (Artropoda: Insecta) in two anpogeno habitats from Venezuela. Rev. chil. entomol. [online]. 2020, vol.46, n.4, pp.725-734. ISSN 0034-740X.  http://dx.doi.org/10.35249/rche.46.4.20.18.

In two hydro-ecological systems of anthropogenic habitats (stabilization-oxidation lagoons), located in the northeast and northwest of Venezuela, a faunistic study was carried out to identify species of aquatic insects, which make life in such highly polluted artificial environments. The collection of the specimens was carried out using two capture methods in five anpogeno microhabitats of the anthropogenic system such as spaqua, supaqua, hercircum, caenum and petra, achieving the registration of 54 species of four orders of aquatic insects (Coleoptera, Hemiptera, Odonata and Diptera), with twelve common species in both areas. The specific richness of the anpogenico habitat of Maracaibo was 49 species, for 20 species in the Araya Peninsula. The Coleoptera order was the most diverse with five families and 39 species. Of the order Hemiptera, seven families and nine species were recorded. Of the orders Odonata and Diptera, three families and three species were registered respectively. The most diverse anpogeno microhabitat was petra with 32 species, caenum with 30 species, spaqua with 12 species, hercicum with four species and supaqua with two species. A total of 25 species occurred in more than one microhabitat. The results constitute the first systematic study on insects associated with stabilization ponds in Venezuela, whose record demonstrated the functionality of artificial wetlands as habitats for a diverse entomological fauna.
