Benefit-cost analysis can be used to evaluate and compare projects that involve alternative mosquito control methods. A comparison of two such projects in Chatham County, GA indicated that source reduction was a contributing factor in the reduction of ground adulticide applications and quantities, and annual female densities per light-trap night of the predominant saltmarsh mosquito species in the area. Net benefits realized from source reduction were $591,319 as opposed to $409,823 and discounted net benefits were $377,729 versus $284,511 (source reduction project vs. chemical control project) demonstrating the relative effectiveness of the source reduction project in our application. Because of unique differences between areas and projects, generalizations of the above conclusion are cautioned, although the approach is easily adapted.
效益成本分析可用于评估和比较涉及替代蚊虫控制方法的项目。对佐治亚州查塔姆县的两个此类项目进行比较表明，减少源头是减少地面杀虫剂施用次数和用量以及该地区主要盐沼蚊虫种类每诱蚊灯夜雌性密度年度值的一个促成因素。减少源头实现的净效益为591,319美元，而化学防治项目为409,823美元，贴现净效益分别为377,729美元和284,511美元（减少源头项目与化学防治项目），这表明了减少源头项目在我们的应用中的相对有效性。由于不同地区和项目之间存在独特差异，尽管该方法易于调整，但对上述结论进行概括时仍需谨慎。
