近30年来,主要以滞留喷洒二二三和合成的新杀虫剂为防制蚊媒阻断疟疾传播的唯一方法。但现在认为这一方法在许多国家对某些蚊媒不再有效。亚洲许多疟疾严重的国家已放弃了消灭疟疾的即期目标,而改为应用现有防制媒介与抗疟药治疗结合的疟疾防治规划。 In the past 30 years, new insecticides, mainly used for spraying two hundred twenty-three and synthesized pesticides, have been used as the only way to prevent the spread of malaria by mosquito control agents. However, this method is now considered to be no longer valid for some mosquito vectors in many countries. Many malaria-ridden countries in Asia have dropped their immediate goal of eliminating malaria and instead replaced their malaria control program with existing anti-malaria drugs in combination with antimalarial treatment.
