Table 2. Results of experimental hut trial of three toxic sugar baits against An. arabiensis and Cx. quinquefasciatus. 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.
