In urban areas, upsurge in population has resulted in more breeding sites for malaria vectors, and hence this scenario potentially undermine malaria elimination and control programs. The change in land use due to urbanization may result in the presence and distribution of malaria vectors. Understanding potential malaria vectors is essential for current and future malaria transmission control strategies. This study investigated the effects of rapid urbanization on malaria vectors An. culicifacies s.l. and An. stephensi L. in Ghaziabad district.
Ghaziabad district which presents several levels of urbanization was selected for this study. Entomological investigations were conducted seasonally from 2014-2016 in the rural, urban, and peri-urban regions. Vector incrimination study was done using ELISA (confirmation by PCR) on suspected Anopheles vectors viz. An. culicifacies, An. stephensi, An. annularis and An. subpictus.
An. culicifacies showed alteration in distribution influenced by rural and agricultural land whereas An. stephensi was found to be influenced by artificial habitats and population growth.
The study also confirms the association between the abundance of malaria vectors and land use change.
在城市地区，人口的增长导致了疟疾传播媒介的滋生地增加，因此这种情况可能会破坏疟疾的消除和控制计划。城市化导致的土地利用变化可能会导致疟疾传播媒介的存在和分布。了解潜在的疟疾传播媒介对于当前和未来的疟疾传播控制策略至关重要。本研究调查了快速城市化对加济阿巴德区疟疾传播媒介按蚊属 culicifacies s.l. 和按蚊属 stephensi L. 的影响。
选择城市化程度不同的加济阿巴德区进行本研究。2014-2016 年，在农村、城市和城乡结合部进行了季节性的昆虫学调查。使用 ELISA（PCR 确认）对疑似疟蚊（按蚊属 culicifacies、按蚊属 stephensi、按蚊属 annularis 和按蚊属 subpictus）进行了媒介定罪研究。
按蚊属 culicifacies 的分布受到农村和农业用地的影响而发生变化，而按蚊属 stephensi 则受到人工栖息地和人口增长的影响。
该研究还证实了疟疾传播媒介的丰度与土地利用变化之间的关联。
