摘要
应用室内饲养观察和田间调查数据拟合了豆蚜Ａｐｈｉｓｃｒａｃｃｉｖｏｒａ种群动态的Ｌｅｓｌｉｅ矩阵模型．模型考虑了温度和湿度对种群的影响，用该模型模拟特定条件下豆蚜未来种群的数量和年龄分布，可靠率达７０％．
Aphis craccivora Kock popularion dynamics Leslie matrix model was fitted from the observational data of laboratory feeding and field investigation.The effects of tempera-ture and humidity on the population dynamics were considered in the model.The reliabity of using this model to simulate the future size and the age distribution of Aphis craccivora popu-lation in special conditions was 70%.
