在加纳西北部的劳拉地区，分发38个月后共收集了255顶蚊帐，以检查其物理状况和残留杀虫剂水平。物理状况各不相同，从几乎完好无损到严重受损。在 50 个选定的网中，统计了 2023 个 >= 0.5 厘米的孔和 31 个 10 厘米的孔。越靠近网的底部边缘，破洞的发生率越高。 50% 的网中发现接缝破损。 64% 的渔网有明显的修复，大部分是缝制的。结合溴 X 射线荧光 (XRF) 光谱测定、高压液相色谱和锥形生物测定，确定 14.9% 的蚊帐保留了完整的杀虫强度。这些结果凸显了有关蚊帐寿命的真实世界数据的价值，可指导有关蚊虫控制策略、蚊帐购买、蚊帐更换频率和产品开发的决策。
A total of 255 bednets were collected 38 months after distribution in Lawra District of northwest Ghana to examine their physical condition and residual insecticide levels. Physical condition varied from nearly pristine to highly damaged. In 50 selected nets, 2023 holes >= 0.5 cm and 31 holes : 10 cm were counted. The incidence of holes increases toward the bottom edge of the net. Seam failures were found in 50% of the nets. Repairs, mostly sewn, were evident in 64% of the nets. Using a combination of bromine x-ray fluorescence (XRF) spectrometry, high-pressure liquid chromatography, and cone bioassays, it was determined that 14.9% of the nets had retained full insecticidal strength. These results highlight the value of real-world data on bednet longevity to guide decisions regarding mosquito control strategies, bednet purchasing, frequency of bednet replacement, and product development.
