Ag3.1: Anopheles gambiae data resource

Released on 17 Nov 2023.


The MalariaGEN Vector Observatory Anopheles gambiae data resource version 3.1 (Ag3.1) contains single nucleotide polymorphism (SNP) calls, copy number variant (CNV) calls and SNP haplotypes from whole-genome sequencing of mosquitoes collected in Mali from 2012 to 2015. Ag3.1 contains 647 whole genome sequences from mosquito samples collected in two locations in Mali. Mosquito species are mostly An. coluzzii, with a smaller number of An. arabiensis and An. gambiae.

Data sets

Ag3.1 Contributing Studies

1177 – Aestivation and migration of An. coluzzii, An. gambiae, and An. arabiensis in the Malian Sahel

Ag3.1 Sample Locations

Mosquitoes were collected in several villages in the Mali Sahel from 2012 to 2015, along two transects centred on the village of Thierola and including Niono, a region of irrigated rice cultivation.

Ag3.1 Terms of Use

Data from this project will be made publicly available before journal publication. Unless otherwise stated, analyses of project data are ongoing and publications are in preparation by project partners, and it is not permitted to use project data for publication (including any type of communication with the general public) without prior permission from the originating partner studies.

Although malaria is generally an endemic rather than an epidemic disease, and the focus of this project is on surveillance of disease vectors rather than pathogens, our data terms of use build on MalariaGEN’s approach to data sharing, and adopt norms which have been established for rapid sharing of pathogen genomic data during disease outbreaks. The primary rationale for this approach is that malaria remains a public health emergency, where ethically appropriate and rapid sharing of genomic surveillance data can help to detect and respond to biological threats such as new forms of insecticide resistance, and to adapt malaria vector control strategies to different settings and changing circumstances.
