摘　　要： 对合肥地区木槿上棉蚜的种群动态进行了研究,结果表明,越冬前棉蚜成蚜和若蚜主要发生于10月下旬至12月上旬,发生高峰期为11月中、下旬,12月上旬以后以卵越冬。棉蚜种群在木槿上呈聚集分布,以植株中、南部分布量最大。二维排序结果表明,木槿上棉蚜种群动态可分为成蚜回迁期、成若蚜高峰期、成若蚜阶段向越冬卵阶段过渡期和越冬卵期4种主要动态类型。 The population dynamics of Aphis gossypii in rose mallow in Hefei has been studied. The results showed that the adults and larvae of A. gossypii occurred mainly in the period from the last ten-day of October to the first ten-day of December in rose mallow before over wintering, and the peak period of their occurrence was from the middle ten-day to the last ten-day of November. After the first ten-day of December, A. gossypii over wintered in the form of egg. The distribution pattern of A. gossypii population in rose mal- low was aggregate and the distribution number was the greatest in the middle and the southern parts of rose mallow. The results of two-dimensional ordination showed that the population dynamics of A. gossypii in rose mallow could be classified into four major dynamic types of immigrating stage of adults, peak stage of adults and larvae, transition stage from adults and larvae to winter eggs and winter egg stage.
