不同仓型惰性粉防治储粮害虫效果研究

摘要

To evaluate the control effects of inert dust against stored-grain insect pests in different types of granaries, by mixing 50 cm thick grain on the surface with the inert dust, the test has been carried out in the com and wheat loaded recently in the large granary, squat silo and silo respectively. The results showed that the inert duct could prevent effectively insect pests occurrence in grain hulks for a longer period, and delay the occurrence time and density of insect. There were no effects on temperature, humidity of the granary and grain quality, instead of the usual chemicals to some extent.%为了评价惰性粉杀虫剂在不同仓型中杀虫应用效果,采用粮堆表层至50 cm处拌粮的方法对高大平房仓、浅圆仓、立筒仓内新入库的玉米和小麦进行试验研究.结果表明:此种惰性粉杀虫剂能在较长的一段时间有效防治粮堆内的害虫发生,并延迟了害虫的发生时间和密度,对仓内温、湿度、粮食品质基本无影响,可以部分取代目前使用的化学防护剂.
