| 摘 要： | 用植物性杀虫剂苦皮藤素Ⅳ(KPT乳油)有效成分30、15mg/kg防治柑橘潜叶蛾,采用离体叶片浸叶法处理5s,3d后,幼虫校正虫口减退率分别为89.63%、63.02%;枝梢浸液法处理5s,5d后,潜道伸长度校正抑制率分别为76.12%和41.51%;10d后,对秋梢的相对保叶效果分别为69.34%和52.29%。结果表明,采用KPT乳油有效成分30mg/kg对柑橘潜叶蛾有较好的控制作用,对柑橘秋梢有良好的保护效果。

| Abstract: | Using the botanical pesticide KPT EC to control the Phyllonistis citrella by leaf and new shoot immersion at the concentration of ai.30, 15 mg/kg respectively, results showed that the moralities of the larvae after 5 days' treatment were 89.63%, 63.02% by 3s' leaf immersion. The lengths of leaf tunnels were inhibited 76.12% and 41.15% by comparing with control. Results revealed that KPT EC could efficiently control the larva of Phyllonistis citrella at the concentration of 30 mg/kg and protects the autumn new shoot of citrus very well. |
