| 摘 要： | 梧桐木虱是一种危害园林植物梧桐的重大害虫。本研究分别测定了12种杀虫剂和5种天敌昆虫对梧桐木虱的防治效果。结果表明: 12种杀虫剂中噻虫嗪和吡虫啉对梧桐木虱的防治效果最好,螺虫乙酯次之。在喷雾法、注射法和灌根法等3种施药方式中,应尽量避免使用喷雾法,优先选择注射法,在条件允许的情况下可使用灌根法作为补充手段。5种天敌昆虫中以中华通草蛉和赤星瓢虫对梧桐木虱的防治效果最佳,在长期防治效果上可以起到代替杀虫剂的作用。因此,中华通草蛉及赤星瓢虫可作为园林环境中长期安全环保防治梧桐木虱的重要方法,而以注射法使用噻虫嗪和吡虫啉可作为短期快速防治手段。

| Abstract: | Thysanogyna limbata is a pest on the landscape plant Firmiana platanifolia. In this study, we evaluated the control efficacy of twelve insecticides and five common natural enemies to T. limbata. The results showed that the control efficacy of thiamethoxam and imidacloprid to T. limbata was much better than other insecticides. For the three application methods evaluated (spraying, injection, and root-irrigation), the spraying method should be avoided and the injection performed better. If conditions permitted, root-irrigation method could be used as a supplementary method. Among the five natural enemies, Chrysoperla sinica and Lemnia saucia had the best control effect on T. limbata, which could replace insecticide in the long-term control effect. Therefore, C. sinica and L. saucia could be used as safe and environment-friendly pattern to prevent T. limbata in the medium- and long-term in the garden, whereas injection of thiamethoxam and imidacloprid could be used as a short-term and rapid treatment. |
