摘　　要：[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 aim was to study control effects of different rice seedling techniques on Lissorhoptrus oryzophilus Kuschel in order to provide reference for controlling the feeding, breeding and spread of overwinter L oryzophilus. [ Method ] Control effects of five rice seed- ling techniques like non-woven and thin film dry rice-nursery, insect net and non-woven watered-seedling and watered-seedling on L. oryzophi- lus were studied. [ Result] Using watered-seedling in seedling bed had the most insects, larva and feed spot, and they were up to 5. 15, 17.17, 117.21 per 100 plant and 1.18, 10.08, 21.48 per clump, which were significantly more than those of the other four seedling tech- niques. [ Conclusion] The non-woven and thin film dry rice-nursery, insect net and non-woven watered-seedling were important techniques measures to control breeding, spreading and damaging of L. oryzophilus.
