1994～1995年,开展筛选防治苹果绵蚜有效药剂的研究工作,结果表明:在苹果绵蚜发生严重的果园,于苹果展叶期(4月中下旬)、苹果谢花后(5月中旬)和苹果幼果期(5月下旬至6月初),抓住苹果绵蚜越冬若虫出蛰期、第1、2次迁移期,全树喷施48％乐斯本乳油1500×液或硕丹35％乳剂1200×液3次,防效可达92.42～100％;为害较轻果园,5月份施药2次,平均防效为92.29％,均可基本控制绵蚜全年为害。乐斯本及硕丹防效显著优于氧化乐果及久效磷。
From 1994 to 1995, the research work on the screening and effective prevention and treatment of apple aphid was carried out.
