棉蚜 ( Aphis gossypii Glover)是安徽沿江棉区棉虫综合治理的主要靶标之一 ,研究其种群动态是搞好棉蚜测报和防治工作的重要基础。棉蚜的种群动态包括种群数量动态、空间动态和时间动态 ,并以整体的水平反映出来 ,因此 ,从数量动态和空间动态的统一观出发研究其种群动态十分必 Cotton aphid (Aphis gossypii Glover) is one of the main targets of integrated management of cotton insects in the cotton fields along the Yangtze River in Anhui Province. Studying its population dynamics is an important basis for doing a better job of forecasting and controlling cotton aphids. The population dynamics of cotton aphid includes population dynamics, spatial dynamics and temporal dynamics and is reflected in the overall level. Therefore, it is very necessary to study its population dynamics from the perspective of the unity of quantitative and spatial dynamics
