泰国从四十年代末开始采用DDT室内滞留喷洒,现在微小按蚊已在平原区消失,仅分布在丛林山麓区。1975年以疟疾控制计划代替根除规划后,DDT的喷洒范围和覆盖面有很大改变,因此有必要再次评价微小按蚊对LDDF不同程度选择压的反应及其对疟疾防治的影响。在泰国北部丛林山区选择有代表性的4个村庄,1、2两村一直使用DDT喷洒,前者喷洒覆盖面较广(至少85%),一年喷2次,后者喷洒覆盖面较少(50%),一年喷洒1次。3、4两村DDT喷洒已分别停止3年和6年。
Thailand has been using DDT indoor detention since the late 1940s, and now Anopheles minimus has disappeared in the plains and is only distributed in the jungle foothills. After the eradication program was replaced by a malaria control plan in 1975, there was a drastic change in the coverage and coverage of DDT. Therefore, it is necessary to re-evaluate the response of the Anopheles stephens to varying degrees of selective LDF pressure and its impact on malaria control. In the northern jungle of northern Thailand, four representative villages were selected. The first and second villages of the two villages always use DDT spraying. The former covers a wide area (at least 85%), spraying twice a year (less than 50% ), Spraying once a year. 3,4 DDT spraying two villages have been stopped for 3 years and 6 years.
