For analyzing and verifying the accuracy of different mosquito monitoring frequencies and monitoring cycles , and developing an optimal mosquito monitoring program, the data obtained by a 224 days continuous monitoring (24 h/d) in 2013 were used as “standard data”, from which systematic -sampling was performed to acquire different “monitoring frequency group”, and then calculate the error rates ( ERs).Meanwhile, different “monitoring cycle models” were established and the population density of adult mosquitoes and the formed ERs were calculated .Then an economic and effective monitoring programme was developed with ERs ≤ 20.0% as the evaluation criteria.As results, the ERs of mosquito population dynamics declined to 19.90% (≤20.0%) when the monitoring frequency increased to 3 times per month, and the average proportion ERs of Cx.pi.pallens and Ae.albopictus declined to 7.01% and 18.10% (≤ 20. 0%) when the monitoring frequency was 2 times per month, therefore, the optimal mosquito monitoring frequency should be 3 times per month.In the same way, the optimal monitoring frequency could be determined to be 2 times per ten-days.As to monitoring cycle, there was no significant difference of mosquito density between period II & III and 24 h monitoring cycle, and the obvious difference in Ae.albopictus population could be corrected by fitting method, therefore II&III period (16: 30-8: 00 the next day) should be determined as an optimal mosquito monitoring cycle.%为验证并分析成蚊不同监测频率及监测周期的准确度，进而确定最优化的监测方案，本文以2013年224天24小时CO2法连续性监测作为“标准数据”，以系统抽样方式从中获取不同“监测频率组合”并计算误差率（ERs），同时比较不同“监测周期组合”计算成蚊种群密度及构成的误差率（ERs），以误差率≤20.0％为评价标准，确定更加经济有效的监测方案。分析显示，月监测频率增加至3次／月时，成蚊消长误差率降至19.90％（≤20.0％）；2次／月时，淡色库蚊与白纹伊蚊构成比平均误差率分别降至7.01％与18.10％（≤20.0％），因此最优的月监测频率为3次／月，同样方法，较优的旬监测频率可确定为2次／旬。监测周期方面， II （16：30～20：00）＋III （20：00～次日8：00）时段监测周期与24 h监测周期比较，成蚊整体密度未见显著差异（92.97 vs 82.98只／天， Z＝－1.480， P＝0.139），白纹伊蚊种群尽管差异显著，但可通过拟合进行校正，因此II＋III时段（16：30～次日8：00）可作为较优的CO2法成蚊监测周期。
