A population model for tsetse species was used to assess the optimal number and spacing of airborne sprays to reduce or eradicate a tsetse population. It was found that the optimal spray spacing was determined by the time (days) from adult emergence to the first larviposition and, for safety, spacing was assigned to that duration minus 2 days. If sprays killed all adults, then the number of sprays required for eradication is determined by a simple formula. If spray efficiency is less than 100% kill per spray, then a simulation was used to determine the optimal number, which was strongly affected by spray efficiency, mean daily temperature, pupal duration, age to first larviposition and the acceptance threshold for control, rather than eradication. For eradication, it is necessary to have a spray efficiency of greater than 99.9% to avoid requiring an excessive number of sprays. Output from the simulation was compared with the results of two aerial spraying campaigns against tsetse and a least squares analysis estimated that, in both cases, the kill efficiency of the sprays was not significantly less than 100%.

为消灭或击倒采采蝇苍蝇Glossina spp的封闭种群建模最佳的杀虫剂喷洒时间和频率。（双翅目：Glossinidae）。
采采蝇物种的种群模型用于评估减少或根除采采蝇种群的空中喷雾的最佳数量和间隔。发现最佳喷雾间隔是由成年到首次幼虫形成的时间（天）来确定的，为安全起见，将间隔指定为该持续时间减去2天。如果喷雾剂杀死了所有成年人，则根除所需的喷雾剂数量由一个简单的公式确定。如果喷雾效率低于每次喷雾杀灭率的100％，则使用模拟来确定最佳数量，该最佳值受喷雾效率，平均日温度，p持续时间，第一次幼虫的年龄和接受控制的阈值的强烈影响。比消灭。为了根除，必须具有大于99的喷雾效率。9％以避免过多喷洒。将模拟的输出与针对采采蝇的两次空中喷洒活动的结果进行了比较，最小二乘分析估计，在两种情况下，喷洒的杀灭效率均不显着低于100％。
