To ascertain the population dynamics and integrated control technologies of red bayberry bat flies (RBBF), a system investigation of occurrence rules, monitoring and forecasting and integrated control was conducted during 2003 to 2015 in Linhai City and Huangyan District in Zhejiang. The results showed that RBBF population had two peaks in mid and late of June and mid of July, fruits were heavily damaged during the fruiting period; Dongkui RBBF population increased mainly because of ultivation, complex orchard environment, winter temperature rising and natural enemies control capacity decreasing. The monitoring and prediction method for RBBF was formulated, and the prediction model was established, the accuracy rate reached 93.3%. Net red bayberry culture technology had obvious prevention effects on RBBF, the damaged fruit rate decreased by 93.61% to 96.25% compared with that of CK; by 60 g/L spinetoram 2000 times liquid sprayed at 45, 30 and 20 d before harvest, RBBF population decreased by 92.94% to 95.72%, damaged fruit rate decreased by 91.56% to 95.78%, and it had fast degradation velocity, which acquired official pesticide
registration. Environmental friendly control technologies were formed based on control strategies on RBBF and To ascertain the population dynamics and integrated control technologies of red bayberry bat flies (RBBF), a system investigation of occurrence rules, monitoring and forecasting and integrated control was conducted during 2003 to 2015 in Linhai City and Huangyan District in Zhejiang.

Environmental friendly control technologies were formed based on control strategies on RBBF and monitoring and forecasting, which combined physical obstruct and agricultural control, which could control RBBF effectively.
