长期以来就要求出口粮食在交货地点无虫害。由于某些主要的贮藏物害虫对马拉硫磷的抗性,替代马拉硫磷的药剂应运而生。近年来其它类型的与有机磷类联合作用的药物在澳大利亚开始使用。有机磷类杀虫剂敌敌畏、马拉硫磷、杀螟松和甲嘧硫磷等能控制住拟谷盗类及象虫科害虫,增效生物苄呋菊酯和除虫菊酯能有效地控制住谷蠹。一些较新的合成除虫菊酯类药剂:二氯苯醚菊酯、苯醚菊酯、杀灭菊酯有希望成为生物的苄呋菊酯的替代物,而溴氰菊酯,当以2毫克/公斤的剂量配合增效醚(10毫克/公斤)施用时,能有效地控制住各主要虫种。
It has long been required that export food be pests-free at the place of delivery. Due to the resistance of malathion to some major storage pests, agents that replace malathion have emerged. In recent years, other types of drugs that work in conjunction with organophosphorus have started to be used in Australia. Organic phosphorus insecticides such as dichlorvos, malathion, fenitrothion and tetramethylphos-methyl can control the imazapyr and insecticidal insects, synergist and regent of resmethrin and pyrethrin can effectively control the valley Beetle. Some of the newer pyrethroid agents: permethrin, phenothrin, fenvalerate are promising alternatives to living resmethrin, while deltamethrin, when administered at 2 mg / Kilo doses with potent ether (10 mg / kg) applied effectively controlled the major pest species.
