In the Australian southeast, the saltmarsh mosquito Aedes vigilax (Skuse) is the focus of area‐wide larviciding campaigns employing the biological agent Bacillus thuringiensis var. israelensis (Bti). Although generally effective, frequent inundating tides and considerable mangrove cover can make control challenging. Here, we describe the efficacy and persistence of an aqueous Bti suspension (potency: 1200 International Toxic Units; strain AM65‐52) within a mixed saltmarsh–mangrove system and the use of affordable unmanned aerial systems (UAS) to identify and map problematic levels of mangrove canopy cover.

空中应用的苏云金芽孢杆菌变种的性能 混合盐沼-红树林系统中的蚊子的以色列配方(AM65-52株),以及使用可负担得起的基于无人机的影像对红树林冠层进行精细比例测绘。

在澳大利亚东南部的盐沼蚊伊蚊vigilax(Skuse)是采用生物制剂大面积杀幼虫活动的重点苏云金芽孢杆菌变种。以色列Bti)。尽管总体上是有效的,但频繁的洪水泛滥和大量的红树林覆盖可能使控制面临挑战。在这里,我们描述了盐沼-红树林混合系统中Bti水溶液悬浮液(效力:1200国际毒性单位; AM65-52菌株)的功效和持久性,以及使用负担得起的无人机系统(UAS)来识别和绘制有问题的水平红树冠层覆盖。
