Dengue is endemic in Malaysia, and vector control strategies are vital to reduce dengue transmission. The strain AlbB carried by both sexes of was released in Mentari Court, a high-rise residential site, in October 2017 and stopped after 20 weeks. frequencies are still being monitored at multiple traps across this site, providing an opportunity to examine the spatiotemporal distribution of and mosquito density with respect to year, residential block, and floor, using spatial interpolation in ArcGIS, GLMs, and contingency analyses. In just 12 weeks, -infected mosquitoes were established right across the Mentari Court site with an overall infection frequency of >90%. To date, the frequency of has remained high in all areas across the site despite releases finishing four years ago. Nevertheless, the invaded more rapidly in some residential blocks than others, and also showed a relatively higher frequency on the eighth floor. The index tended to differ somewhat between residential blocks, whilst the index was relatively higher at the top and bottom floors of buildings. In Mentari Court, only a short release period was required to infiltrate completely and stably into the natural population. The results inform future releases in comparable sites in a dengue control programme.
登革热在马来西亚呈地方性流行，病媒控制策略对于减少登革热传播至关重要。2017年10月，在高层住宅地曼塔里苑释放了两性携带的AlbB品系，20周后停止释放。目前仍在该地点的多个诱捕器监测其频率，这提供了一个机会，利用ArcGIS中的空间插值、广义线性模型和列联分析，研究其时空分布以及蚊子密度与年份、住宅街区和楼层的关系。仅在12周内，曼塔里苑整个区域就建立起了感染该品系的蚊子，总体感染频率超过90%。尽管释放工作在四年前就已结束，但迄今为止，该品系在整个地点所有区域的频率仍然很高。然而，该品系在一些住宅街区的入侵速度比其他街区更快，并且在八楼的频率也相对较高。该品系指数在不同住宅街区之间往往有所不同，而该品系指数在建筑物的顶层和底层相对较高。在曼塔里苑，只需要较短的释放期就能使其完全且稳定地渗入自然种群。这些结果为登革热控制项目中类似地点的未来释放工作提供了参考。
