In first experiment, two termiticides; fipronil and imidacloprid of specific formulation 25 EC&nbsp;and 5% SC, respectively, were used. Different concentration dilutions were prepared and termites? mortality&nbsp;assay was performed. Both formulations gave 100% termites mortality on their highest ppm concentration&nbsp;after one week. Second experiment was based on different spore concentrations of Metarhizium anisopliae&nbsp;that were applied on worker termites to check the lethal concentration of fungi. It was observed that spore&nbsp;concentration showed direct relationship with termites? mortality which means, as the spore concentration&nbsp;increases, termite mortality also increases. Last experiment was conducted to check the synergistic effect&nbsp;of M. anisopliae and termiticides. The fungus was used in combination with termiticides, fipronil and&nbsp;imidacloprid, separately. The rate of mortality of termites which exposed to imidacloprid/fipronil and&nbsp;M. anisopliae simultaneously was higher than mortality of termites exposed to either treatment alone.</p> ER -
