【摘要】 桔红片盾蚧是严重危害女贞的重要害虫。采用吡虫啉、啶虫脒、阿维菌素3种药剂吊瓶输液防治试验表明,0.9%阿维菌素100倍液每株200 mL在女贞第1盘枝以下10 cm插针吊瓶输液,防效达95.0%以上。该蚧应重点防治第1代盛期若虫或成虫,最适防治时间为5月上旬,最迟不超过7月下旬。该法防治药效长,污染小,几乎不杀伤天敌,不受天气影响,可在生产中推广应用。更多还原

【Abstract】 Aonidiella aurantii(Maskell) is an important pest which damaged Ligustrum lucidum seriously.The tests on controlling Aonidiella aurantii by Imidacloprid,Acetamiprid and Abamectin using flask infusion indicated that: the control rate was more than 95% when a 100 fold 0.9% Abamectin solution was infused into the trunk of L.lucidum at the point of 10 cm lower under the lowest branch with 200 mL per individual tree.The first generation peak nymphs or adults of the pest should be focused on prevention.The optimal control period was the first ten day of May,and the latest time could not be later than the end of July.This control method lasted for a long time with little pollution and almost no destruction on natural enemies.The control method was not affected by bad weather,it could be promoted and applied in practice.更多还原
