Biodiversity of Insects in the Amazon: survey of social wasps (Vespidae: Polistinae) in Amazon rainforest areas in Amazonas state, Brazil

Abstract

The thematic network ‘Biodiversity of Insects in the Amazon’ is the first network among researchers of the Brazilian Amazon in terms of the increase of knowledge and provision of subsidies for the conservation of Amazonian biodiversity, focusing on insects, and disseminate this knowledge to different sectors of society. In this way, expeditions to six localities in the Amazonas State were carried out and we present here the results for social wasps (Vespidae: Polistinae). We used two modified Malaise traps combined with two suspended traps from July 2016 to June 2017. A total of 140 species and 20 genera were collected: 92 species and 18 genera in ZF-2-Manaus area, where the greatest diversity was recorded, followed by Tefé (73 species, 16 genera), Careiro-Castanho (72 species, 17 genera), Novo Airão (71 species, 16 genera), Presidente Figueiredo (62 species, 16 genera), and Ipixuna (58 species, 17 genera). Metapolybia rufata Richards, 1978 and Polybia diguetana du Buysson, 1905 were new records for Brazil, and other six species were first records for Amazonas state. The results indicate that further investigations should significantly increase the species diversity of wasps in the Amazon region and add more information to the knowledge of Polistinae diversity.
