The acaricidal activity of emamectin benzoate against the tea red spider mite, Tetranychus kanzawai was evaluated in laboratory bioassays. Treatment with emamectin benzoate at concentrations of 10.75-3.58 ppm was highly effective against the adult female of T. kanzawai and yielded 100% adulticidal activities at 1 day after treatment. The adult females exposed to emamectin benzoate at concentrations of 10.75-3.58 ppm produced 0-0.5% as many eggs as did the control females. Emamectin benzoate was ineffective against the eggs of T. kanzawai, however treatment at 10.75 and 5.38 ppm revealed 100 and 90% larvicidal activity within 24 h after hatching, respectively. Treatment with emamectin benzoate at 10.75-3.58 ppm was highly effective against the nymphs of T. kanzawai and exhibited 97.8-100% nymphicidal activities. Based on the results, emamectin benzoate could be used for the control of T. kanzawai and treatment at 5.38 ppm was recommended for further field tests.
