Abstract
BACKGROUND
In this semi-field study, a new polymer-enhanced deltamethrin formulation, K-Othrine PolyZone, was compared to a standard deltamethrin product for residual activity against a susceptible strain of laboratory-reared Anopheles gambiae using standard WHO cone bioassays.
METHODS
Residual insecticide efficacy was recorded after exposure to metal, cement and wood panels maintained in experimental huts in sub-tropical environmental conditions in north central Florida, USA, and panels stored in a climate controlled chamber located at the Centers for Disease Control and Prevention, Georgia, USA.
CONCLUSIONS
K-Othrine PolyZone demonstrated 100% control on metal and cement panels 1 year post application and > 80% control on wood panels up to 6 mo. The new formulation should be considered for use in indoor residual spray programmes requiring long-term control of malaria vectors.
摘要
背景
在这项半现场研究中，一种新型聚合物增效的溴氰菊酯制剂 K-Othrine PolyZone 与一种标准的溴氰菊酯产品进行了比较，使用标准的世界卫生组织锥形生物测定法，针对实验室饲养的对杀虫剂敏感的冈比亚按蚊品系，测试其残效活性。
方法
在佛罗里达州中北部亚热带环境条件下的实验棚屋中，金属、水泥和木板暴露于杀虫剂后，记录残留杀虫剂的功效，木板还被保存在佐治亚州疾病控制和预防中心的气候控制室内。
结论
K-Othrine PolyZone 在施药后 1 年对金属和水泥板的控制率达到 100%，对木板的控制率高达 6 个月，超过 80%。新配方应考虑用于室内滞留喷洒方案，以长期控制疟疾媒介。
