茶梢蛾在四川一年发生一代,以幼虫在枝梢内和叶内越冬。越冬幼虫于5月上旬—8月中旬在枝梢内化蛹,成虫于5月下旬—8月底羽化,产卵于叶柄附近及枝梢裂痕中,6月下旬—9月下旬初孚幼虫侵入叶片潜斑为害,10月中旬后转蛀枝梢危害。防治的关键时期是在幼虫潜叶期(8—10月),用90%敌百虫500倍至1000倍液,均匀喷布于叶背,防治效果可达90%以上。成虫初盛期和盛期用90%敌百虫1400倍、2700倍液,连续 A generation of tea shoot moths occurs in Sichuan a year, with larvae wintering in the shoots and leaves. Overwintering larvae in early May to mid-August in the shoots of pupation, adults in late May to the end of August feather, spawning in the petiole near the branches and cracks in the late June - September early Fu larvae invade the leaves Potential damage spot, after mid-October turn boreholes shoot damage. The key period of control is in the larvae of the leaves (8-10 months), with 90% trichlorfon 500 times to 1000 times the liquid, spray evenly distributed on the back, the control effect of up to 90%. Adults early and peak use of 90% trichlorfon 1400 times, 2700 times the liquid, continuous
