A study was conducted in Suriname on the effects of DDT residual house spray on the main vector of malaria, Anopheles darlingi. Results obtained with an experimental hut sprayed with DDT wettable powder (2 g/m2 AI) were compared with results obtained with an unsprayed control hut. In the sprayed hut, entry rates were reduced by 32% and feeding success by 43.6%. The 24-h mortality of mosquitoes which entered the sprayed hut was 95% (range 85-100%) over the 10-month study period. After furnishing the sprayed hut according to local custom, no reduction in mortality was observed despite an abundance of unsprayed resting surfaces. Bioassays showed that the DDT deposits remained effective for at least 14 months. With excito-repellency test boxes an irritant effect caused by DDT on recently fed An. darlingi females was shown. With a choice-box experiment no preference for unsprayed over sprayed resting places could be demonstrated.
在苏里南开展了一项关于滴滴涕室内残留喷洒对疟疾主要传播媒介达林按蚊影响的研究。将一间喷洒了可湿性粉剂滴滴涕（有效成分2克/平方米）的实验小屋的结果与一间未喷洒的对照小屋的结果进行了比较。在喷洒过的小屋里，蚊子进入率降低了32%，叮咬成功率降低了43.6%。在为期10个月的研究期内，进入喷洒小屋的蚊子24小时死亡率为95%（范围85%-100%）。按照当地习俗布置喷洒小屋后，尽管有大量未喷洒的栖息表面，但未观察到死亡率降低。生物测定表明，滴滴涕沉积物至少14个月内仍有效。通过兴奋驱避试验箱显示，滴滴涕对近期进食的达林按蚊雌蚊有刺激作用。通过选择箱实验，未证明蚊子对未喷洒的栖息处比对喷洒过的栖息处有偏好。
