[OBJECTIVE] Study on the control effects of the mixture of Emamectin Benzoate and Enspray against Ectropis obliqua warren or Acaphylla theae walt. [METHOD]To do the Comparison Experiment by us-ing two kinds of mixture, 3000 times Emamectin Benzoate and 300 times Enspray, 2500 times Emamectin Ben-zoate and 250 times Enspray, and using two kinds of agricultural chemicals, m000 times ethion and m000 times dimethoate, before the High Day for the second generation of Ectropis oblique and the first peak of Acaphylla theae walt in the north of Guangxi province.[RESULTS]The Control Effects of the two kinds of mixture against Ectropis obliqua on 2st, 7rd, 40th days later: 82.46%-87.78%,93.95%-97.36%,83.33%-88.39%. And the con-trol effects of the two kinds of agricultural chemicals against Ectropis obliqua on 2st, 7rd: 81.78%-76.32%, 77.97%-75.45%. The number of worms 30th later is as same as before using the chemicals. The control effects of the two kinds of mixture against Acaphylla theae walt on 2st, 2mth, 40th days later. 85.15%-89.13%, 96.91%-98.70%, 93.84%-95.59%. And the Control Effects of the two kinds of agricultural chemicals against Acaphylla theae walt on 2st, 21th: 90.07%-71.81%, 35.35%-31.17%.the number of worms 30th later is assame as before using the chemicals. [CONCLUSION] the Mixture of Emamectin Benzoate and Enspray have good control effects and long lasting time against Ectropis obliqua warren or Acaphylla theue walt, and can be ex-tended on tea-Harmless production.
