Entomofauna edáfica em diferentes ambientes no município de Ipu, estado do Ceará

Abstract

The aim of this study was to map the soil entomofauna in two different environments, in the District of Recanto, Municipality of Ipu, in the northwest region of the state of Ceará, Brazil, using soil trap, with fortnightly collections in the period from November 2015 to March 2016. In order to characterize the insect fauna a distribution pattern was established, considering the rates of occurrence and dominance of specieswhich have been grouped by order, as an indicator of the frequency and the occurrence of the amount captured. Throughout the project, a total of 2.171 specimens of insects belonging to 8 orders: Blattodea, Coleoptera, Diptera, Hemiptera, Hymenoptera, Isoptera, Lepidoptera and Orthoptera have been collected and identified. According to the method used the order Hymenoptera was the one that stood out for having the largest number of individuals captured, due to the presence of a large amount of ants, it was considered common to the different environments studied in the caatinga biome.
