The residual potential of an aqueous solution of Deltamethrin (FW 25 mg i.a./m) was evaluated on raffia curtains. These are sheets of synthetic material used in the construction of huts to house miners. Experiments were conducted during 420 days and the curtains were always rolled up in the daytime and unrolled in late afternoon. Data analyzed by logarithmic regression indicated that raffia treated with Deltamethrin had higher mortality indices than that covered with DDT. The residual capacity of Deltamethrin on raffia was high. The mortality percentage was above 85% after 360 days and dropped to about 50% at 420 days. The effect of DDT was reduced after 180 days and reached zero by the end of the experiment. Based or the results of these experiments, it is recommended that Deltamethrin be used to spray raffia curtains in mining regions and other areas that are endemic for malaria.
在酒椰叶纤维窗帘上评估了溴氰菊酯水溶液(25毫克/平方米腹腔注射剂量)的残留潜力。这些是用于建造矿工居住小屋的合成材料片。实验进行了420天,窗帘在白天总是卷起来,傍晚展开。通过对数回归分析的数据表明,用溴氰菊酯处理的酒椰叶纤维比用滴滴涕覆盖的具有更高的死亡率指数。溴氰菊酯在酒椰叶纤维上的残留能力很高。360天后死亡率百分比高于85%,在420天时降至约50%。滴滴涕的效果在180天后降低,到实验结束时降至零。基于这些实验结果,建议在矿区和其他疟疾流行地区使用溴氰菊酯喷洒酒椰叶纤维窗帘。
