对泰国北部山区村庄疟疾病媒发生情况进行了2年的监测。微小按蚊的幼虫和成虫密度均在5、6月份和11、12月份达到高峰。在这些时期，溪流的稳定条件可能有利于微小按蚊的繁殖。溪流中也出现了较高的水平密度，那里约3/4的水面阳光充足，急流和慢流交替出现，水是清澈的。一种。黑斑潜蝇在6、7月份达到高峰，而黑斑潜蝇则在6、7月份达到高峰。迪鲁斯几乎没有季节性变化。三种媒介的密度在越多的山区村庄中越高。
Malaria vector occurrence in mountainous villages was monitored for 2 years in north Thailand. Both larval and adult densities of Anopheles miniumus peaked in May or June and in November or December. Stable conditions in streams during these periods possibly favored the breeding of A n. miniumus. Higher lalval density also was encountered in streams where ca. 3/4 of the water surface was sunlit, portions with rapid currents and slow currents alternate, and the water waS clear. An. maculatus sensu lato peaked in June or July, while An. dirus scarcely changed seasonally. The densities of the three malaria vectors were higher in more mountainous villages.
