粮食仓库的空仓杀虫消毒工作,属清洁卫生防治范畴,它是根据储粮害虫的生态特性,为杜绝仓虫传播感染并为储粮提供良好的环境条件以及实现四无(无虫、无霉、无鼠雀和无事故)粮仓打好基础,也是贯彻“以防为主,防治并举”的保粮方针的重要措施之一。多年来使用一种空仓杀虫药剂,如七十年代用高丙体六六六,现在各地普遍使用的敌敌畏,加之不少地区不按操作规程,又盲目加大用药量,致使部份仓虫产生抗药性,同时也会造成对粮食的污染。因此,选用新的杀虫药剂,交替使用或添加增效剂,能有效地避免仓虫产生抗性和提高
It is based on the ecological characteristics of stored grain pests, in order to prevent the spread of cercariae insects and provide good environmental conditions for the grain storage and the realization of four no (no worms, mold-free , No warbler and no accident). The granaries lay a good foundation and are also one of the important measures to implement the principle of “prevention first and prevention and control simultaneously.” Over the years the use of a short-lived insecticide, such as the seventies with high-C66, now commonly used around the dichlorvos, combined with many areas do not follow the rules, but also blindly increase the dosage, resulting in some cercariae produce resistance Medicinal properties, but also cause pollution of food. Therefore, the choice of new insecticide, alternating use or add synergist, can effectively prevent the emergence and increase resistance
