研究了新型绿色储粮防护剂硅藻土、惰性粉和植物源杀虫剂苦皮藤素在高大平房仓进行实仓防虫应用效果研究。结果表明:硅藻土、惰性粉和苦皮藤素能在较长的一段时间对粮堆内的玉米象和赤拟谷盗的发生进行有效防治,延迟害虫的发生时间和密度,防治效果顺序是:惰性粉>硅藻土>苦皮藤素,同时对仓内平均粮温及粮食品质等无影响,基本达到防治储粮害虫的要求,实现一定的经济效益,可以在部分条件下取代目前使用的化学防护剂。
The effects of diatomite, inert powder and cecropin, a green protective agent for grain storage on pest control in high-storey warehouse were studied. The results showed that diatomite, inert powder and cetopalin could effectively control the occurrence of corn and red tarragon in the grain heap for a long period of time, delayed the occurrence time and density of pests and the order of control effect Is: inert powder> diatomaceous earth> celangulin, at the same time on the warehouse average grain temperature and grain quality has no effect, basically achieve the prevention and control of grain pests requirements, to achieve certain economic benefits, under some conditions to replace the current The use of chemical protective agent.
