Table 1 Age-group classification of Anopheles gambiae s.l. females before and after a single application of ASB (control) or ATSB (experimental treatment) on local vegetation

From: Successful field trial of attractive toxic sugar bait (ATSB) plant-spraying methods against malaria vectors in the Anopheles gambiae complex in Mali, West Africa
