Abstract

This paper deale with the nest suucture and aeralion system of Cornllermes cumu/ans (KoIIar, 1832) (Isoptera, Termitidae), an imporlant insect pest species existing in areas requidng rnechanizadon. The structure was studied by cutting longitudinal Intersections of the nesl, The aeration system was analyzed by
using a motorized thermonebulizator and a powder insuflator. The resulta indicated that the powder injection process did not provide information as to lhe structures involved with aeration. However, lhe tog produced by lhe therrnonebulizator showed to be efficient to demonstrale lhe importance of the cavity that surrounds the nest base, in the aeralion.
