Expanded geographic distribution and host preference of Anopheles gibbinsi (Anopheles species 6) in northern Zambia | Malaria Journal

Nchelenge District in northern Zambia suffers from holoendemic malaria transmission despite a decade of yearly indoor residual spraying (IRS) and insecticide-treated net (ITN) distributions. One hypothesis for this lack of impact is that some vectors in the area may forage in the early evening or outdoors. Anopheles gibbinsi specimens were identified in early evening mosquito collections performed in this study area, and further insight was gleaned into this taxon, including characterizing its genetic identity, feeding preferences, and potential role as a malaria vector. Mosquitoes were collected in July and August 2019 by CDC light traps in Nchelenge District in indoor sitting rooms, outdoor gathering spaces, and animal pens from 16:00–22:00. Host detection by PCR, COI and ITS2 PCR, and circumsporozoite (CSP) ELISA were performed on all samples morphologically identified as An. gibbinsi, and a subset of specimens were selected for COI and ITS2 sequencing. To determine risk facto

Africa s inland blue economies are in deep water

Maritime security is not limited to activities at sea – inland waterways are also part of the maritime domain, says the African Union (AU). Africa’s Great Lakes, several of which are among the largest water bodies in the world, are the lifeblood for surrounding communities numbering tens of millions of people. This means that maritime security and blue economies require the attention not just of Africa’s coastal states but land-linked countries too. The continent’s lakes and rivers are increasingly threatened by illicit fishing, depredation of marine resources, illegal immigration and territorial disputes emanating from unclear borderlines.
