前言 我国大多数城乡居民家中部有贮存一定数量各类食品的习惯,加大米、面粉、豆类、干果、中药材滋补品等等。但每当春暖花开,梅雨季节到来时,此类食品常常容易遭受虫蛀,霉菌为害,所造成的损失难以计数。为了减少虫、霉为害的损失,曾经有人使用能挥发辛辣气味的物品,如大蒜、花椒、柑桔果皮等置于盛米容器之中,虽能起到一定拒虫效果,但对于虫害已经发生的大米、面粉等,防虫效果欠佳。至于当前大型国家粮库使用杀虫药剂为磷化铝片剂、DDVP、马拉硫磷等。由于此类药剂存在毒性高,操作不安全,以及环境污染、农药残留等问题,若将此种方法用于防治普通城乡居民家庭贮藏食品中的害虫。显然是行不通的。 Foreword Most of the urban and rural residents in our country have the habit of storing a certain amount of various kinds of food in the central part of the country, increasing the supply of rice, flour, beans, dried fruits and Chinese herbal medicines. However, when spring comes, the rainy season comes, such foods are often susceptible to moth-eaten, mold damage, the damage caused by countless. In order to reduce the damage caused by insects and mildew, some people used volatile aromatic substances such as garlic, Chinese prickly ash, citrus peel and so on in a container containing rice, which can play a certain role in repelling insects, but pests have already occurred Rice, flour, etc., poor pest control effect. As for the current large-scale national grain depot insecticide used for aluminum phosphide tablets, DDVP, malathion and so on. Due to their high toxicity, unsafe operation, and environmental pollution and pesticide residues, such methods are used to control pests in food stored in ordinary urban and rural households. Obviously does not work.
