Attractive toxic sugar bait (ATSB) methods decimate populations of Anopheles malaria vectors in arid environments regardless of the local availability of favoured sugar-source blossoms

Table 1 Age structure, population parameters, and vectorial capacity (VC) of female Anopheles sergentii before and after ATSB treatment on day 12
