Table 4.
Impact of exposure to LLINs containing permethrin and/or pyripoxyfen on mosquito mortality and egg development. An. gambiae Tiassalé strain were exposed to the LLINs for 3 min. Mortality was measured 24 h later and surviving mosquitoes offered a blood meal. Ovary dissections were performed 5 days later. n bloodfed accounts for the number of surviving mosquitoes that fed on blood and survived for five days until ovary dissections.
