Jixian County is located in the northern part of Tianjin, south of Yanshan Mountain and northern edge of North China Plain. The total area of cultivated land is 54,000 hm2, of which 25,000 hm2 is planted with wheat. Wheat aphids occur on a large scale every year. Wheat management measures, the use of advanced technology is particularly important. We use oily wheat pesticides and application of electrostatic spray technology to control wheat aphids, the relative control efficiency of 96% or more, the efficacy can be maintained 20 days. Anti-static spray better than the conventional effect of spraying, the effect of more than 10 to 15 days longer than normal spray, and provincial labor
