摘要
研究了储粮防护剂硅藻土、惰性粉和植物源杀虫剂苦皮藤素在高大平房仓实仓防虫应用效果。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Sitophilus zeamais Motschulsky和赤拟谷盗Tribolium castaneum(Herbst)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。
In this paper, the effect of new green stored grain protectants diatomaceous earth, inert dust and botanical insecticides Celastrus palmatine applied in large warehouse had been studied. The results showed that ： diatomaceous earth, inert dust and celangulin can control Sitophilus zeamais Motschulsky and Tribolium castaneum （Herbst） in gain bulk for longtime, delay pest occurence time and pest density, of the order the control effect：inert dust〉diatomaceous earth〉celangulin, have no effect on the average grain temperature and grain quality, reaches the requirements of the prevention and control of stored grain pests, achieve certain economic benefits, can replace the currently used chemical protectants in pant of condition.
