| 摘 要： | 研究棉蚜在不同温度下取食不同生育期棉叶后种群的变动情况。通过Weibull函数模拟、生命表分析和高氏距离分析比较表明，无论在苗期和蕾期，随着渐度的升高棉蚜种群的死亡高峰日均提前，世代寿命明显缩短；然而，在20-25℃范围内，相同温度时棉蚜生活在棉花蕾期叶上的繁殖力明显高于苗期叶上的繁殖力。在30℃时繁殖力普遍明显下降，温度20-25℃最适于棉蚜的生长与繁殖。且棉花殖生长期比营养生长期更适于棉蚜的生存和繁殖，温度与棉花生育期都是导致苗蚜与伏蚜生长与繁殖差异的外界因素。

| Abstract: | Cotton aphid,\%Aphis gossyipii\% is found on various plants with universal distribution.It causes serious damage on cotton and vegetable in China,especially in northwest droughty or semi-droughty areas.The population of cotton aphid differentiates obviously in types.On cotton,the population density usually have two peak periods.One occurs in spring with green or yellowish green body colour,infests the top tender leaves,it is usually called as seedling type;the other is in summer in blight yellow colour and ... |
