Abstract

The importance of testing molecules, as a strategy to chemical control, concerns the use of a selective product with high efficiency against the pests combined with the residual power; and this product should be environmentally, economically and operationally viable. The objective of this research was to study the chemical control of mound-building termites Cornitermes cumulans (Kollar) (Isoptera: Termitidae). The study was conducted in pasture, at the Estância Nelore located at km 236 of highway BR-163 in the municipality of Caarapó, Mato Grosso do Sul State, Brazil, during the period from November 6th to December 6th, 2007. Four active ingredients (A.I.) were evaluated: imidacloprid, fipronil, deltamethrin and chlorpyriphos, at the dosages of 0.60 g, 0.20 g, 1.0 g and 1.2 g, respectively, applied per termite monticule. A completely randomized design with five treatments and ten replications was adopted. The treatments were represented by the control group and the four A.I.’s. Each replication consisted of one active termite mound about 50 cm in height. The chosen termite mounds were identified with lime based paint. To calculate the efficiency of A.I.s tested, the Abbott formula was used. Means were compared by multiple comparison test U of Mann-Whitney with significance level of 5%. The results demonstrated the high potential of chlorpyriphos in controlling C. cumulans.
