为解析不同品种陆地棉的棉铃性状之间关系,本研究调查和分析了采自不同地区的376份陆地棉品种的11个棉铃性状多样性。结果表明:(1)11个棉铃相关性状间的变异系数均大于10%,不同性状的变异系数为籽棉重>体积>壳重>铃重>壳厚>铃容重>横径(上)>横径(下)>纵径>横径(中)>壳重率,说明棉花的产量易受环境影响;(2)相关性分析表明纵径与横径(上,中,下)、体积、壳厚、壳重、籽棉重、铃重呈极显著正相关,与壳重率和铃容重呈极显著负相关;壳厚与纵径、横径(中)呈极显著正相关,与体积呈显著正相关;(3)主成分分析表明:第1个主成分中,棉铃的重量和长度对第1个主成分影响较大,尤其是铃重对第1个主成分影响最大;第2个主成分主要反映单位体积的铃重;第3主成分中,壳重率的特征向量正值最大,因此第3主成分可以表示为铃壳占铃重的比例;第4个主成分中,壳厚的特征向量最大;(4)聚类分析结果表明376份陆地棉可分为大铃、中铃和小铃3个类群,说明所选材料具有一定的差异性,能够代表陆地棉品种材料。本研究结果为深入评价棉铃性状间的遗传多样性及品种选育提供理论依据。

为了解棉平突蚜茧蜂Lysiphlebia japonica(Ashmead)对取食不同寄主植物棉蚜Aphis gossypii Glover的偏好性,进行了相关的虫口动态、寄生率和体重等参数的调查。虫口动态结果表明,棉田和罩笼中西葫芦上棉蚜、棉平突蚜茧蜂和僵蚜数量均最多,与棉花和黄瓜上的相比有显著差异。室内和罩笼中西葫芦上棉蚜的体重较大,约0.36 mg,显著高于棉花和黄瓜上的棉蚜体重。室内寄生试验结果表明,棉平突蚜茧蜂在西葫芦上对棉蚜的寄生率较高,其中来源于西葫芦上的棉平突蚜茧蜂对西葫芦、棉花和黄瓜上蚜虫的寄生率分别为81.3%、58.3%和44.0%。本文初步明确了棉平突蚜茧蜂对西葫芦具有偏好性,为棉平突蚜茧蜂在生物防治上的应用提供一定的理论指导和实践依据。

随着化学农药的大面积推广使用,棉蚜的抗药性问题变得越来越突出,结合使用生物防治法来延缓或治理棉蚜抗药性问题已迫在眉睫。本研究在常规管理棉田条件下,对不同作物混栽区苗期6种作物上棉蚜及其主要天敌的种群动态进行了调查。结果表明,西葫芦上的棉蚜种群数量最大(峰值,11016.7头/百株),其次是四季豆(峰值,6323.3头/百株),棉花、黄瓜、豇豆和甜瓜上的棉蚜则相对较少,且其种群动态发生具有一致性。6种作物上的主要天敌的种群发生都滞后于棉蚜的发生,并以寄生蜂的种群密度最大,且具有指数增长效应。在本试验条件下,西葫芦上棉蚜数量多,僵蚜基数大,是室内饲养寄生蜂的良好寄主。
