摘　　要：80％敌百虫可溶性粉剂防治荔枝蝽的田间药效试验结果表明，每667m。用药量为66．67～120g时，药后1d的防治效果为79．25％～86．32％．药后3～7d的防治效果为97．56％～100％，且荔枝树生长安全，试验期间无药害现象发生。田间防治荔枝蝽时．每667m。的用药量以66．67g左右为宜。The effect of 80% trichlorphon soluble powder on Tessaratoma papillosa in field trials was researched. The results showed that applying 80% trichlorphon soluble powder with dosage of 66.67-120 g/667m^2, the control effect reached 79.25%-86.32% after 1 d application, the control effect reached 97.56%-100% after 3-7 d application. Meanwhile, there was no obvious phytotoxicity in litchi tree. For controlling T. papillosa, 80% tricblorphon soluble powder recommended dosage should be 66.67 g per 667 m^2.
