Constraints on rubber plantations are the pest attacks of Coptotermes curvignathus which cause losses in rubber production. This study was aimed to determine the effect of bioinsecticides of Bacillus thuringiensis in controlling C. curvignathus. Research was designed in Completely Randomized Design (CRD). Test insects used as applications were 1).worker termites, 2). soldiers, 3). worker termites and soldiers (mix). The results of spore calculations showed that treatment of 14g addressed the highest level of spore density while the lowest level of spore density was found in the treatment of addition 2 g of golden snail shell flour. Symptoms of Bacillus thuringiensis infection were characterized by changes in body color to dark brown with swollen abdomen followed by soft termite bodies when touched. The soldier caste with reduced equipment was not able to eat independently so that the deaths that occur are more due to this.} }
