Arthropod diversity associated with cowpea cultivation and forest fragment in establishment of family farming in South-eastern Pará

Abstract

Cowpea and forest fragments, in interaction with arthropod communities, are of great importance
in family farming. Therefore, the aim of this study was to evaluate the diversity of arthropods
associated with cowpea cultivation and forest fragment in establishment of family farms in
southeastern Pará. Sampling was carried out with four traps like trap door at ground level with
three replications in the dry season and three in the rainy, the agricultural cycle in 2012/2013
cowpea cultivation and adjacent forest fragment. We collected 7834 individuals belonging to
13 orders and 174 morphospecies. Bean farming showed higher diversity and abundance with
66.2% of the individuals. But the forest fragment was the richest. Both environments showed
high diversity. Thus, it is concluded that the adjacency of bean cultivation to forest fragment
was one of the factors that favored the diversity of arthropods in this area.
