Community prospection of Isoptera in forest agrosystems with brazilian mahogany cultivation (Swietenia macrophylla King.) in the Amazon

Abstract

Termites have social structure consisting of individuals who form colonies interdependent with each other. Develop and promote hemimetabolia by overlapping generations where males and females are divided into categories or castes. This work aimed to make the prospect of Isoptera community forest agrossystems with Brazilian mahogany cultivation. The study was conducted in the dry and rainy seasons of 2015 in Brazilian mahogany plantations, samples were taken with the use of pitfall traps, where they remained in the area for 48 hours, which were Brazilian mahogany monoculture area; Agroforestry system of Brazilian mahogany with African mahogany, neem and Australian cedar; and successional forest area enriched with mogno brasileiro. The faunal analyzes were performed Spade program. Found families Termitidae, Kalotermitidae and Rhinotermitidae in the areas studied in the dry period, the number of individuals of Termitidae family was higher in Agroforestry System, and less in the area of successional forest. In the rainy season, to Termitidae obtained a lower value in the SAF area (159 ± 67), and in the dry season was the highest value; similar reduction was observed in monocropping (197 ± 170). Rainfall was decisive in reducing the number of Isoptera three families studied.
