| 摘 要： | 二化螟Chilo suppressalis(Walker)]是一种钻蛀性害虫,具有食性杂、越冬场所多、转株为害等特点,其种群数量近年来呈回升趋势,危害逐年加重。二化螟对寄主存在明显的选择行为,其主要寄主之一水稻由于品种更替、耕作制度变更及气候变化等因素对二化螟种群发生规律产生了一些新的影响,给害虫防治工作带来了许多新问题。研究和了解二化螟的寄主选择规律及其机制,以及影响其种群动态的因素是有效调控二化螟种群的重要前提。本文就二化螟寄主选择行为与机制及其在水稻上种群消长影响因素等的研究概况进行综述报道,旨在更好地为二化螟的综合防治提供指导。

| Abstract: | The rice stem borer,Chilo suppressalis(Walker),one of the most destructive rice insect pests in temperate and subtropical Asia,causes increasing damage and yield loss to rice in many rice-growing regions in recent years due to changes in rice varieties,cultural practices and global climate.Further,the rice stem borer shows preference in selecting host plants.Determination of host selection behavior and elucidation of its underlying mechanisms and the factors responsible for the new changes in population dynamics of the rice stem borer are important in developing integrated management strategies.In this paper,host selection behaviors and the underlying mechanisms,and the factors affecting population dynamics of the rice stem borer were discussed. |
