本文主要研究内容
作者刘欢,钟玉琪,侯茂林(2019)在《湘桂走廊单双季稻混栽稻田稻纵卷叶螟、稻飞虱及其天敌的种群动态》一文中研究指出:2017年和2018年在处于湘桂走廊的广西兴安县设置田间小区试验,研究了单、双季稻混栽稻田中水稻"两迁"害虫及其天敌的种群动态。结果表明,早稻上稻纵卷叶螟Cnaphalocrocis medinalis Guenée基本为迁入型,中稻上为迁入+本地繁殖型或迁出型,晚稻上为迁出型。稻纵卷叶螟的落卵量在5月底至6月下旬为全年高峰,集中在早稻拔节期至孕穗期;这导致早稻田6月下旬至7月初卷叶发生严重。鉴定到稻纵卷叶螟寄生性天敌11种,其中幼虫寄生主要发生在早稻和中稻前期。稻飞虱种群数量在早稻和中稻田较高,早中稻上以白背飞虱Sogatella furcifera Horváth为主,晚稻上以褐飞虱Nilaparvata lugens Stål为主。捕食性天敌种群数量在水稻生育期的中后期较高,前期较低;晚稻田的蛛虱比高达1.4-6.3。这些结果表明,单、双季稻混栽时,早稻和中稻上"两迁"害虫发生为害较重,晚稻上较轻;这与水稻生产季节前期迁入的"两迁"害虫数量高有关,也与生产季节中后期天敌的控害作用增强有关。
