() is an effective biological insecticide for killing mosquito larvae. However, choosing the suitable application method for larviciding is critical in increasing its effectiveness. Therefore, this study aimed to determine the effectiveness of (VectoBac) WG using various applications at high-rise buildings. Three different applications of treatment were applied at three high-rise buildings in Bandar Saujana Putra. The ULV machine is used for Pangsapuri Impian, a mist blower for Pangsapuri Seri Saujana and a pressured sprayer for BSP 21. BSP Skypark does not undergo treatment and acts as a control. The efficacy of treatment was measured by analyzing the ovitrap surveillance data collected (POI and MLT) for pre and post-treatment. Post-treatment ovitrap surveillance indicates that the Aedes sp. mosquito density was lower than the density at the time of pre-treatment surveillance. Overall, the species in both an indoor and outdoor environment setting had shown a reduction. The highest Aedes sp. density reduction is seen through the use of mist blowers in outdoor settings for , (%POI reduction = 87.4%; %MLT reduction = 93.8%). The mist blower yielded results that is significantly higher compared to other larviciding applications; the order from greatest to the least was mist blower > pressured sprayer > ULV. It can be concluded that each application produces different degrees of effectiveness in reducing the Aedes sp. density in different environmental settings.
（）是一种杀灭蚊虫幼虫的有效生物杀虫剂。然而，选择合适的杀幼虫应用方法对于提高其有效性至关重要。因此，本研究旨在确定在高层建筑中使用不同应用方式的（VectoBac）WG的有效性。在布城莎阿南的三座高层建筑中应用了三种不同的处理方式。在Impian公寓使用超低容量喷雾机，在Seri Saujana公寓使用喷雾器，在BSP 21使用压力喷雾器。BSP空中花园未进行处理，作为对照。通过分析处理前后收集的诱蚊产卵器监测数据（POI和MLT）来衡量处理的效果。处理后的诱蚊产卵器监测表明，伊蚊属蚊子密度低于处理前监测时的密度。总体而言，在室内和室外环境中该物种数量均有所减少。在室外环境中对（）使用喷雾器时伊蚊属密度降低幅度最大（POI降低率 = 87.4%；MLT降低率 = 93.8%）。喷雾器产生的效果明显高于其他杀幼虫应用方式；从效果由高到低的顺序为喷雾器 > 压力喷雾器 > 超低容量喷雾机。可以得出结论，每种应用方式在不同环境中降低伊蚊属密度时产生不同程度的效果。
