世界各国卫生用杀虫剂,消费量逐年增加,虽然住房的木楼建筑逐步淘汰,白蚁的威胁不如过去,但是蚊、蝇、蟑螂、蚂蚁、老鼠各国都有。有些国家如要消灭一座大厦的害虫或一列火车,一艘邮船的某些害虫是要出动较大的人力,物力,好象进行一场战役。从杀虫剂消费量的增加来看,也是世界性的,尤其是日本卫生杀虫剂的生产量发展很快,已外销数十个国家,虽然各国卫生用的杀虫剂消费量很大,但是还没有一个国家完全可以消灭害虫。尚有许多害虫在某些杀虫剂的长年使用下产生了抗性。而害虫的繁殖力很强,怎样彻底消灭害虫是目前值得研究的问题。不过目前看来,在火车、轮船、飞机或住宅消灭害虫,国外生产的杀虫剂品种还是很多。例如:在有机氯杀虫剂方面尚未产生抗性的有地耳剂(497),林丹。磷二氯苯,二溴化乙烯,都能杀死卫生害虫。禁止使用六六六,
The consumption of sanitation insecticides in various countries in the world has been increasing year by year. Although the construction of wooden buildings in housing is phased out, the threat of termites is not as good as in the past, but mosquitoes, flies, cockroaches, ants and mice all over the world. In some countries, to eliminate pests or a train from a building, some of the pests of a mailing ship may have to exaggerate their manpower and material resources as if they were a campaign. The increase in the consumption of pesticides is also worldwide. In particular, Japan’s production of sanitation pesticides has been developing rapidly and has been exported to dozens of countries. Although the consumption of sanitation pesticides in various countries is very high, But no single country can kill pests completely. There are many pests that are resistant to long-term use of certain pesticides. The pest fecundity is very strong, how to eliminate pests is currently worth studying. However, it seems that there are still many varieties of pesticides produced abroad by eliminating pests in trains, ships, planes or houses. For example: Aphrodisiacs that have not developed resistance to organochlorine pesticides (497), Lindane. Phosphorus dichlorobenzene, ethylene dibromide, can kill health pests.
