Amount and spatial dynamics of population of Bemisia tabaci(Hemiptera:Aleyrodidae) in different host plants

  • 摘要: 对不同寄主植物烟粉虱(Bemisia tabaci)种群动态研究结果发现,不同寄主植物烟粉虱种群数量达高峰的时间有所差异,波幅也不一致,12种作物烟粉虱种群数量依次为油葵>西葫芦>棉花>大豆>南瓜>茄子>丝瓜>番茄>辣椒>黄瓜>菜豆>玉米,说明烟粉虱对其寄主植物具有一定的自然选择性。用扩散系数(C=S/X)对烟粉虱在棉花、油葵和大豆作物田空间分布型初步分析结果均为聚集分布型。
    Abstract: The population dynamics of Bemisia tabaci (Gennadius) in different host plants were studied.The results indicate that the times in which the populations of B.tabaci on different hosts increase to a peak are different,the ranges of population wave are also different,the order of population densities of B.tabaci on different hosts is sunflower>pumpkin>cotton>soybean>cushaw>eggplant>hechima>tomato>chili>cucumber>kidney bean>corn,which indicates that B.tabaci to host-plant has definite nature selectivity.Spatial distributions of B.tabaci in cotton,sunflower and soybean fields are studied by using C=S2〖KG-*3〗/〖KG*4〗〖AKX-〗,and they are of collective distribution type.
