Durable lining (DL) is a deltamethrin-impregnated polyethylene material, which is designed to cover domestic walls that would normally be sprayed with residual insecticide. The operational success of DL as a long-lasting insecticidal substrate will be dependent on a high level of user acceptability as households must maintain correctly installed linings on their walls for several years. Preliminary trials were undertaken to identify a material to develop into a marketable wall lining and to assess its level of acceptability among rural and urban populations.
In Angola (n=60), prototype DL and insecticide-treated plastic sheeting (ITPS) were installed on urban house walls and ceilings, respectively, and acceptability was compared to indoor residual spraying (IRS) (n=20) using a knowledge, attitude and practice (KAP) questionnaire. In Nigeria (n=178), three materials (prototype DL, ITPS and insecticide-treated wall netting) were distributed among rural and urban households. User opinions were gathered from focus group discussions, in-depth interviews and KAP questionnaires.
In Angola, after two weeks, the majority of participants (98%) expressed satisfaction with the products and identified the killing of insects as the materials' principal benefits (73%). After one year, despite a loss of almost 50% of households to refugee repatriation, all 32 remaining households still asserted that they had liked the DL/ITPS in their homes and given the choice of intervention preferred DL/ITPS to IRS (94%) or insecticide-treated nets (78%). In Nigeria, a dichotomy between rural and urban respondents emerged. Rural participants favoured wall adornments and accepted wall linings because of their perceived decorative value and entomological efficacy. By contrast, urban households preferred minimal wall decoration and rejected the materials based upon objections to their aesthetics and installation feasibility.
The high level of acceptability among rural inhabitants in Nigeria identifies these communities as the ideal target consumer group for durable wall linings. The poorer compliance among urban participants suggests that wall linings would not be readily adopted or sustained in these regions. If DL is as well received by other rural populations it could overcome some of the logistical constraints associated with spray campaigns and has the potential to become a long-lasting alternative to IRS in malaria endemic areas.
耐用衬垫（DL）是一种浸渍了除虫菊酯的聚乙烯材料，旨在覆盖通常需要喷洒残留杀虫剂的家庭墙壁。DL 作为一种长效杀虫剂衬垫的实际效果将取决于其用户的高度接受度，因为家庭必须在数年内正确地在墙壁上安装衬垫。为了开发出一种可销售的壁衬并评估其在城乡居民中的接受程度，我们进行了初步试验。
在安哥拉（n=60），原型 DL 和经杀虫剂处理的塑料片（ITPS）分别安装在城市房屋的墙壁和天花板上，使用知识、态度和实践（KAP）问卷比较了其与室内滞留喷洒（IRS）（n=20）的接受程度。在尼日利亚（n=178），三种材料（原型 DL、ITPS 和经杀虫剂处理的壁网）分发给城乡家庭。通过焦点小组讨论、深入访谈和 KAP 问卷收集了用户意见。
在安哥拉，两周后，大多数参与者（98%）对产品表示满意，并认为杀虫是这些材料的主要优点（73%）。一年后，尽管由于难民遣返，有近 50%的家庭流失，但所有 32 个仍留在家里的家庭仍表示，他们喜欢家里的 DL/ITPS，如果有选择，他们更喜欢 DL/ITPS 干预而不是 IRS（94%）或经杀虫剂处理的蚊帐（78%）。在尼日利亚，城乡受访者之间出现了分歧。农村参与者更喜欢墙壁装饰，并因其装饰价值和昆虫学功效而接受墙壁衬垫。相比之下，城市家庭更喜欢最少的墙壁装饰，并基于对其美观和安装可行性的反对意见而拒绝这些材料。
尼日利亚农村居民的高接受度表明这些社区是耐用壁衬的理想目标消费群体。城市参与者的合规性较差表明，在这些地区，壁衬不太容易被接受或持续使用。如果 DL 也受到其他农村人口的欢迎，它可能会克服与喷雾运动相关的一些后勤限制，并有可能成为疟疾流行地区 IRS 的长期替代品。
