Comparison of the efficiency and performance of two systems and three membranes for blood feeding mosquitoes
Abstract: Objective Due to different concerns in using appropriate mosquito blood feeding techniques, this work focused on evaluating the effectiveness of two artificial mosquito feeding systems (Rutledge and Hemotek) and three different membranes (Parafilm, mouse and chicken skins). Female mosquitoes from an An. coluzzii strain aged between 2 and 5 days were exposed to blood with the two systems at time intervals (5, 10, 15, 20, 25 and 30 min) with blood used on the day of collection, the next day and 2 days after. Results Our results showed that the Hemotek system gave better blood feeding rates than the Rutledge system. Among the three membranes, the blood feeding rates with chicken and mouse skins were higher than those provided by the Parafilm membrane. Likewise, blood stored 1 day after collection gave higher levels than blood used on the day of collection and 2 days after. Regardless of the system, the lowest blood feeding rates were observed at 5 min compared to the other exposure times.
