In order to grasp the occurrence and development of wheat aphid, the wheat aphid population growth and decline was observed in the wheat fields of Northwest Pear in Beibei, Chongqing in 1954-1955. At the same time, it conducted a survey on the fixed schedule of the nearby production team, Maidi, and went to places such as Tongliang, Baxian, Hechuan, Chengdu, Neijiang, Jianyang, Longchang, Jiangjin and Zunyi, Guiyang, Anshun, 198 wheat fields (including different soils, topography, varieties, sowing dates).
