Table 1. Laboratory bioassays of three toxic sugar baits against An. gambiae s.s., An. arabiensis, and Cx. quinquefasciatus in cage tests. Numbers of female mosquitoes tested, the percentage dying, the percentage dyed with a red dye, and the percentage of dyed mosquitoes that died (and 95% confidence intervals) are presented.
