Entomofauna associada a cultivo de soja e fragmento florestal em Sinop Mato Grosso

Abstract

The Insect class is highly diverse and plays important roles in the balance and functioning of ecosystems. The objective of this work was to quantify the entomofauna associated with the cultivation of soybeans and forest fragments located in the municipality of Sinop, Mato Grosso. Two collections were carried out using Pit-fall, Moericke and flight interception traps, installed in three transects, 50m equidistant. In each transect, collection points were demarcated located, from the limit of the forest fragment, at 10m, 30m and 50m into the soybean cultivation area, and at the same distances entering the area of the forest fragment. The pit-fall and flight intercept traps remained in the field for 48 hours and the Moericke remained for 24 hours. In all, 5,119 insects were collected, 1,641 associated with soybean cultivation and 3,478 with the forest fragment. Thirteen orders were identified, with the highest abundance Hymenoptera and Diptera with 3,365 and 552 respectively. The greater abundance of insects in the forest fragment suggests that it presents better conditions for insect development and survival.
