Ag1000g - BURKINA FASO (2)


Locations: Burkina Faso (BF)

Partner study description

Samples were contributed from collections of indoor resting adults made by spray catch from Monomtenga in central Burkina Faso (12.06, -1.17). These specimens were sorted morphologically to An. gambiae s.l.. Ovaries of half-gravid females were dissected and placed in numbered individual micro-tubes containing modified Carnoy’s solution (1:3 glacial acetic acid: 100% ethanol). Carcasses were placed in correspondingly numbered micro-tubes over desiccant. Genomic DNA was isolated from individual mosquitoes using one of the following: DNeasy Extraction Kit (Qiagen, Valencia, CA), Puregene kit (Gentra Systems, Inc., Minneapolis, MN), DNAzol kit (Molecular Research Center, Inc., Cincinnati, OH.) or Easy-DNA kit (Invitrogen, Carlsbad, CA). An. gambiae s.s. and its molecular forms were identified using one of two rDNA-based PCR/RFLP assays, (1) or (2). Ovaries from specimens of the desired species were subject to polytene chromosome analysis.
