丽水市橘小实蝇绿色防治技术探索与应用评价OA

As an extremely important pest species in the citrus industry of Lishui City,Bactrocera dorsalis has been raging all year round,seriously affecting the quality of citrus fruits and causing a significant reduction in orchard yields.In order to explore green prevention and control methods for Bactrocera dorsalis in Lishui City and obtain a synergistic,efficient,and economically effective green prevention and control method for Bactrocera dorsalis,this demonstration experiment evaluated two green prevention and control methods(Tephritidae adhesive board and Tephritidae food attractant)for Bactrocera dorsalis in the citrus orchard in Lishui City.The results showed that applying the Tephritidae adhesive board in the initial occurrence period of Bactrocera dorsalis can effectively reduce the number of male Bactrocera dorsalis and indirectly affect the mating of male and female adult Bactrocera dorsalis.And the application of Tephritidae food attractant in the peak spawning period of Bactrocera dorsalis can effectively control the population number of Bactrocera dorsalis,especially the female Bactrocera dorsalis,reducing the damage caused by egg-laying.This demonstration experiment has a prevention and control effect on Bactrocera dorsalis of up to 86.61%,providing a scientific reference for the promotion and application of green prevention and control technologies for Bactrocera dorsalis in Lishui City.
