[目的]探究不同育秧方式对稻水象甲的控制效果,为有效控制稻水象甲越冬代成虫的取食、繁殖及扩散提供借鉴。[方法]研究了利用无纺布旱育秧、薄膜旱育秧、防虫网水育秧、无纺布水育秧、水育秧5种不同育秧方式对稻水象甲的控制效果。[结果]水育秧处理在秧田期和大田期的稻水象甲成虫、幼虫和取食斑数最多,分别达5.15头/百株、17.17头/百株、117.21个/百株和1.18头/丛、10.08头/丛、21.48个/丛,而其他4种育秧方式处理在秧田期和大田期的稻水象甲成虫、幼虫和取食斑数均显著低于水育秧处理。[结论]在稻水象甲发生区,利用无纺布旱育秧、薄膜旱育秧、防虫网水育秧和无纺布水育秧都是控制稻水象甲繁殖、传播与危害的重要技术措施。
[Objective] The research aimed to explore the control effects of different methods of seedling on water chestnut A, and to provide references for controlling the feeding, reproduction and spreading of rice water weevil over the winter. [Method] The control effects of 5 different types of seedlings for water-weevil treatment on waterfowl weevil were studied using non-woven fabric such as dry nursery seedling, film dry nursery stock, insect-proof net watering seedling, nonwovens watering seedling and watering seedlings. [Result] The results showed that the number of adults, larvae and feeding larvae of Larval asiatica larvae were the highest in seedling stage and field stage respectively, reaching 5.15 / 100, 17.17 / 100, 117.21 / 100 and 1.18 / Plexus, 10.08 head / plexus and 21.48 / plexus, while the other four kinds of seedlings were significantly lower than that of watering seedlings in the seedling stage and in the field. [Conclusion] It is an important technical measure to control the propagation, spread and harm of Weevil in water chestnut weevils using the non-woven fabric of dry nursery stock, film dry nursery stock, insecticidal net watering seedling and non-woven fabric seedling.
