采用模糊聚类分析方法对麦蚜种群动态进行分析,揭示出麦蚜种群的发生规律及特点。其种群动态有5个状态集。在麦蚜防治中,应注意发生盛期A_2的种群动态。当种群发展到A_4′状态时,种群将自然下降。
Fuzzy cluster analysis was used to analyze the population dynamics of wheat aphids, revealing the occurrence and characteristics of wheat aphids population. Its population dynamics have five state sets. In wheat aphid control, should pay attention to the occurrence of peak A_2 population dynamics. When the population develops to A_4 ’state, the population will naturally decline.
