There is provided a composition for forming an aerosol, an aerosol sprayer for insect pest mating disruption, and a method for insect pest mating disruption, thereby reducing disadvantageous effects caused by falling to a ground surface and oxidative decomposition of the sprayed particles. More specifically, there is provided the composition including an aerosol stock solution containing an aliphatic linear aldehyde having 10 to 20 carbon atoms and a non-alcoholic diluent, and a propellant, wherein a weight ratio of the aerosol stock solution to the propellant is from 45:55 to 65:35; the sprayer including the composition and a pressure resistant container for enclosing the composition therein, wherein sprayed particles at a spray travel distance of 15 cm have a median particle size (Dv50) at 25°C of from 35 to 65 µm by a volume-based cumulative particle size distribution and; the method using the aerosol sprayer; and the like.
本发明提供了一种用于形成气溶胶的组合物、一种用于扰乱害虫交配的气溶胶喷雾器和一种用于扰乱害虫交配的方法,从而减少了因喷洒颗粒落到地面和氧化分解而造成的不利影响。更具体地说,所提供的组合物包括含有具有 10 至 20 个碳原子的脂肪族线性醛和非
酒精稀释剂的气溶胶原液以及推进剂,其中气溶胶原液与推进剂的重量比为 45:55 至 65:喷雾器包括组合物和用于将组合物封闭在其中的耐压容器,其中在 15 厘米的喷雾行程距离上,按基于体积的累积粒度分布计算,在 25°C 时喷出的颗粒的中值粒度(Dv50)为 35 至 65 微米;使用气溶胶喷雾器的方法;以及类似方法。
