摘　　要：本文报道茶蚕颗粒体病毒（ＡｂＧＶ）液剂与ＡｂＧＶ杀虫双复合液剂田间防治茶蚕的效果。ＡｂＧＶ液剂６００ｍｌ／ｈｍ ２ 防治卵盛孵期至低龄幼虫期的效果可达８０．４％ ～９１．１％ ，并有明显的持效，施药后１～３ 年，茶蚕的自然感病率仍达４７．６％ ～６２．３％ ；ＡｂＧＶ杀虫双复合液剂（３００ｍ ｌ／ｈｍ ２）防治卵盛孵期至幼虫３龄前幼虫的效果可达８６．２％ ～９７．５％ 。９～１０月以应用复合液剂较好，能加快死亡速度。Results of field application of Andraca bipunctata granulosis virus (AbGV) sprays against the tea caterpillar are reported in this paper The control effect of the AbGV spray at 600ml/ha was 80 4%~91 1%, and the effect was increased to 86 2%~97 5% when low dose of a chemical insecticide Shachongshuang was added into the virus spray (300ml/ha) Field observations made continuously for 5 years showed that the above sprays also had persistent effect on the caterpillar population However, the AbGV spray owing to its higher virus content was significantly more effective than the mixed preparation 1~3 years after application of the AbGV spray 47 6%~62 3% of the caterpillars were still infected by the virus
