    摘要:

    惰性粉气溶胶防虫技术是通过风机驱动使气溶胶化惰性粉以气固两相流的形式均匀分布到粮堆粮粒空隙内的技术。研究了平房仓横向通风系统下惰性粉气溶胶防治害虫的效果。结果显示,气溶胶的施用方式对于粮堆中扁谷盗类害虫具有很好的杀虫效果,当实测气溶胶浓度低于0.5 mg/kg左右时,害虫死亡率接近100%。

    Abstract:

    The new technology that the food grade inert dust was sprayed into space and driven into the interspace of grain pile by ventilation fans is called technology of food grade inert dust aerosol control insects. The effect of the new technology was assessed by the test in grain store houses with transverse ventilation. Results showed that the aerosol phase of the inert powder can take the particles initiative to come into contact with pests of the grain heap to kill the pests. When the aerosol concentration was about 0.5 mg/kg, many kinds of pests in the grain store houses, especially Cryptolestes pusillus, were effectively killed.
