Propoxur applied aerially at 4.7 liters/ha was an effective adulticide against organophosphate resistant Culex tarsalis. Applications by fixed-wing and helicopter underslung spray systems equipped with hydraulic nozzles provided good coverage of test areas as indicated by the mortality patterns of sentinel mosquitoes. However, the propoxur wettable powder in larvicide oil formulation was dispersed in a very broad particle range. The fixed-wing (Ayres Thrush) aircraft treated 260 ha (640 acres) in 45 min and could carry a full load of 1500 liters (400 gal) at temperatures in excess of 38 degrees C. In contrast, the helicopter (Bell UH-1) with an underslung spray system (Simplex Model 6800) required over 2 hrs to treat the same area at lower temperatures and could not carry a full load of 570 liters (150 gal) at temperatures greater than 38 degrees C.
以4.7升/公顷的用量进行空中喷洒残杀威，是一种针对对有机磷具有抗性的致倦库蚊的有效成虫杀虫剂。配备液压喷嘴的固定翼飞机和直升机悬挂式喷雾系统进行的喷洒作业，根据哨兵蚊的死亡模式表明，对试验区有良好的覆盖效果。然而，杀幼虫油制剂中的残杀威可湿性粉剂粒径分布范围非常广。固定翼（艾尔斯画眉）飞机在45分钟内处理了260公顷（640英亩）土地，在温度超过38摄氏度时可满载1500升（400加仑）。相比之下，配备悬挂式喷雾系统（辛普克斯6800型）的直升机（贝尔UH - 1）在较低温度下处理相同面积需要2个多小时，在温度高于38摄氏度时无法满载570升（150加仑）。
