Performance of sampling methods of Coleoptera associated with carcasses

Resumo

We examined the performance of three different coleopterofauna sampling methods associated with pig carcasses in an area of Caatinga. In order to capture these insects we used different traps including trays, pitfall, and modified Shannon, during the dry and rainy seasons. A total of 4 851 individuals were collected, belonging to 88 species. Active collection using trays was the most abundant (4 474), followed by pitfall traps (328), and modified Shannon (49). Observed high complementarity values (ranging from 0,67 to 0,89), among the three types of collection methods, demonstrate the importance of using the three methods in conjunction to obtain sampled richness. The richness estimators Chao1 and ACE have confirmed the efficiency of the assembly, which was responsible for fathering more than 70% of the richness estimated for both seasons.
