空间喷雾杀虫剂是降低户外苍蝇数量的有效方法。由于减少使用有机溶剂避免环境污染的要求愈来愈高,水作为稀释剂的使用已经发展起来。比较两种稀释剂水和柴油的蒸汽压,可知水蒸发后形成的水滴很细小,以致雾滴太小而不能有效冲击靶昆虫。本文据在非洲做的试验评价用水作稀释剂的一种新方法。喷雾结果表明,降低雾滴中的失水比率会导致更有效的雾云。这项试验被记录为控制家蝇的优秀水平。 Spraying space insecticides is an effective way to reduce the number of outdoor flies. The use of water as a diluent has been developed due to the increasing need to reduce the use of organic solvents to avoid environmental pollution. Comparing the vapor pressures of the two diluents, water and diesel, shows that water droplets formed after evaporation of water are so small that the droplets are too small to effectively impact the target insect. This article is based on a pilot study in Africa to evaluate a new method of using water as a diluent. Spray results show that reducing the water loss ratio in droplet results in a more efficient fog cloud. This test is documented as controlling the excellent level of housefly.
