【Objective】 The objective of this study was to study the effect of ultra-low-dose spraying 2% thiacloprid microcapsule suspension on the prevention and control of Tamarix chinense apple Xiaotingding and provide the theoretical basis for the prevention and control of Tiaoshan wild apple. 【Method】 The density of insects in the operating area and the control area before and after the aircraft operation were investigated to calculate the rate of decrease and the control effect. 【Result】 The result showed that the reduction rate of the population in the operation area of aircraft control reached 95.00%, and the control effect reached 65.82%. 【Conclusion】 The ultra-low-volume aerosol spray controlled the Tiandan wild fruit apple Xiaotingding, which has the advantages of high operation efficiency, low control cost and good control effect. It can be popularized in a large area in the serious damage area of apple Xiaotingding.
