DIVERSIDADE DE LIBÉLULAS (Odonata: Libellulidae) EM SISTEMAS LÊNTICOS DO BREJO PARAIBANO AREIA - PB 2017

Abstract

The order Odonata is divided into three suborders, Anisozygoptera, Zygoptera and Anisoptera, with only the last two occurring in Brazil. The insects belonging to this order are considered as bio indicators of degraded environments, showing the importance of characterizing their diversity. In this sense, the objective of this research was to characterize the diversity of dragonflies in springs present in Campus II of the Federal University of Paraíba (UFPB). The capture of the insects was carried out in four freshwater lakes with the aid of aerial insect nets, through random walks on the lakes' banks. Sampling was carried out biweekly from September 2015 to June 2016, covering two seasonal periods (rain and drought), between the hours of nine in the morning and five in the afternoon. The diversity of insects was calculated through the application of faunal indexes and population fluctuation. The individuals captured belong to the family Libellulidae, being distributed in two subfamilies (Libellulinae and Corduliinae), comprising a total of 12 genera. In view of this, it is concluded that the UFPB Campus II sources present a relevant diversity of insects of the family Libellulidae, which contributes to the knowledge of Odonata fauna for the region.
