摘　　要：[目的]明确0.6%烟碱·苦参碱乳油对柑橘矢尖蚧的防治效果及对其天敌的安全性评价。[方法]利用喷雾法测试不同剂量0.6%烟碱·苦参碱乳油和25%喹硫磷乳油对柑橘矢尖蚧的田间控制效果,同时调查施用0.6%烟碱·苦参碱乳油后柑橘捕食性天敌瓢虫种群数量。[结果]0.6%烟碱·苦参碱乳油对柑橘矢尖蚧具有较高的防治效果,可达到98.21%,且该药剂对柑橘捕食性天敌瓢虫具有一定的安全性。[结论]0.6%烟碱·苦参碱乳油可作为一种综合防治柑橘矢尖蚧的轮换药剂大面积推广应用,使用质量浓度以15~20 mg a.i./L为宜。[Aims] The paper aims to evaluate the field efficacy ofnocotine .matrine 0.6% EC to Unaspis yaranenais Kuwana and its safety to ladybugs in citrus field. [Methods] The population control efficacy ofnocotine.matrine 0.6% EC was evaluated in field trails. [Results] The results indicated that the control effect ofnocotine.matrine 0.6% EC to U. yanonens/s Kuwana was 98.21%, and was safe to the ladybugs in citrus field. [Conclusions] As an alternative pesticide for comprehensive management of U. yanonersis Kuwana, nocotine .matrine 0.6% EC could be utilized in a large-scale in citrus field. The reasonable dosage ranges from 15-20 mg a.i./L.
