Abstract：The summer season in the old course of the Yellow River is characterized by rainy and hot weather,which creates a favorable environment for the breeding and growth of Bactrocera dorsalis.Furthermore,the promotion of bag free cultivation techniques for early and mid maturing apple varieties has created even more favorable conditions for the outbreak of B.dorsalis,which seriously affects the quality and yield of local apples.This article summarized the occurrence pattern of fruit flies in apple orchards along the Yellow River's ancient course.Since the first discovery of adult fruit flies in apple orchards along the old course of the Yellow River in 2014,it had been monitored every year that fruit flies pose a threat to apple fruits.Four to five generations occurred in an apple orchard every year,with the adult onset period from mid July to mid November.The first peak of adult onset occured in early August,and the larval hazard period was from mid August to mid September.The pupae overwinter in early November,but could not survive safely.Then it analyzed the causes of occurrence and comprehensive prevention and control methods,in order to provide technical reference for the prevention and control of fruit fly in apple orchards in the region.
