Impact of w AlbB on the life span of An. stephensi . Mosquitoes were provided with either 10% sucrose only (A and B) or blood meals to females (C). One day after eclosion (A and B) or a blood meal (C), males or females were individually transferred to mesh-covered cardboard buckets with 10% sucrose available. The dead mosquitoes were removed with an aspirator and recorded daily. The curves represent the mean percentage of mosquitoes surviving from three biological replicates each day. Both female and male LB1 mosquitoes lived significantly longer than did LIS mosquitoes (P = 0.0017 for (A); P = 0.0095 for (B); log-rank test) when maintained on sucrose alone. There was no significant difference in the life span of blood-fed females between LB1 and LIS mosquitoes (C).
