  The chemical insecticides used in soil against the subterranean termites result in polluting of soil ecosystems and become causes of human health hazards because of such risks, there is a need of developing ecofriendly baits for the control of these termites. With this objective, a study was carried out to evaluate the termiticide potential of ethanol extract of bark; ethanol-water, hexane and ethyl acetate fractions of bark and ethyl acetate fraction of leaf of Croton urucurana against the subterranean termite, Heterotermes sulcatus (Hagen). The experiments were performed in the laboratory with 100 foraging workers of this termite using no-choice bioassay method. Filter paper treated with crude extract and fractions of C. urucurana at concentrations of 250, 500, 1000, 3000, 5000, 8000 and 10,000 ppm were used. A piece of filter paper treated with respective solvent only was used as a control e.g., control 1 (water), control 2 (ethanol solvent). The substitute variables evaluated were daily mortality, lethal concentration LC50 and LC95 and lethal time LT50 and LT95. It was found that the crude extract and ethanol-water fraction resulted in the lowest LC50 and LC95 values as well as these formulations also presented lowest LT50 and LT95 values among all the treatments, hence making these formulations most toxic among the tested ones against H. sulcatus, C. urucurana seemed to have bioactive compounds with termiticide effect and it can be considered as potential alternative to synthetic insecticides for the control of termites.
