在泰国Phare省的2个村庄进行了一项实地研究，以评价20%杀螟松微胶囊制剂（Sumithion 20 MC R）对微小按蚊种群的滞留喷洒效果。在处理村，除2户选择喷洒0.5g/m2杀螟松进行对比生物测定试验外，其余均喷洒1g/m2杀螟松。生物测定结果表明，该虫的死亡率为100%。在1g/m2-30分钟内，直到喷雾后4个月，最小值为100%。的增长速度。在研究期的前4个月，治疗村的最小种群数量低于对照区。这些结果表明，杀螟硫磷微胶囊在旱季开始时的残留喷洒在喷洒后至少4个月内是有效的，并且可以抑制An的密度。minimus。
A field study was carried out in 2 villages of Phare Province, Thailand to evaluate effect of the residual spraying of a microcapsulated formulation of 20% fenitrothion (Sumithion 20 MC R) on Anopheles minimus populations. In the treatment village, houses were sprayed with I g/m2 of fenitrothion, except for 2 houses which were selected to spray with 0.5 g/m' of fenitrothion for comparative bio-assay test. The results of bio-assay test showed that mortality of An. minimus was 100% in I g/m2-30 miniutes until 4 months after the spray. The growth rate of An. minimus population during the first 4 months of the study period in the treatment village was lower than that in the control area. These results suggested that the residual spray of fenitrothion microcapsules at the beginning of the dry season was effective at least for 4 months after the spray and could suppress the density of An. minimus.
