The study was an attempt to capture Anopheles stephensi from cattle sheds during dawn to understand the realistic density of the resting mosquitoes. A 2-year longitudinal study was carried out in cattle sheds in close proximity to the human dwellings to collect the resting vector mosquitoes. The man-hour density of An. stephensi ranged from 24.7 to 206.5. The vector incrimination results indicated 0.15% of An. stephensi infected with Pv210 in 2015 and 0.09% in 2016. The current study indicated that cattle sheds are still the preferred resting place of An. stephensi and that dawn is the perfect time to collect and estimate its densities. Hence, adult vector control may also be given due importance in addition to the routine larval source management measures to curb malaria transmission in an urban setting.
本研究试图在黎明时分从牛棚中捕获致倦库蚊，以了解休息中蚊子的实际密度。在靠近人类住区的牛棚中进行了为期 2 年的纵向研究，以收集休息中的媒介蚊子。致倦库蚊的人时密度范围为 24.7 至 206.5。媒介定罪结果表明，2015 年有 0.15%的致倦库蚊感染了 Pv210，2016 年为 0.09%。本研究表明，牛棚仍然是致倦库蚊的首选栖息地，黎明是收集和估计其密度的最佳时间。因此，除了常规的幼虫源管理措施外，成虫媒介控制也可能得到应有的重视，以遏制城市环境中的疟疾传播。
