Abstract:
This study elucidated the influence of blood meal type on reproductive performance of Anopheles gambiae s.s. Starting from three days old, An. gambiae mosquitoes, from a laboratory colony maintained following standard anopheline rearing techniques, were offered seven different blood meal types, through an artificial membrane. Thereafter, the mosquitoes were monitored for pre-larval and immature stage reproductive attributes. The results indicated that except for Embryony Period (EP) and Pupal Stage Duration (PSD), all attributes investigated varied significantly (p<0.05) among blood meals. While Blood Feeding Rate (BFR) was significantly highest and least in groups of mosquitoes fed with human (Mean = 94.69±3.36%) and pig (Mean = 48.54±10.13%) blood meals, respectively; the shortest Pre-oviposition Period (POP) were recorded among mosquitoes given human and cattle blood meals (Mean = 3.96±0.88 and 4.30±1.25 days, respectively). Also, human blood meal was the most ideal for Oviposition Rate (OR) (Mean = 79.20±12.39%) while chicken and pig blood meals were the least favourable (Mean = 46.80±9.55 and 48.05±6.34%, respectively). Fecundity (F) had similar distribution pattern as BFR while Egg Hatching Rate (HER) was generally low (<60%), irrespective of blood meal type. While Total Immature Stage Duration (TISD) varied widely among blood meal types, Total Larval Stage Duration (TLSD) was only significantly (p<0.05) longest in mosquitoes fed with pig blood meal (12.33±1.63 days). The epidemiological implications of these results were highlighted and discussed.
