Effects of deltamethrin exposure on mosquito mortality in kdr-L1014S homozygous resistant An. gambiae (s.s.) mosquitoes. Mortality is shown (a) under low (< 25.3 °C) and high temperature (≥ 25.3 °C) conditions; (b) under low (< 69.7%) and high relative humidity (≥ 69.7%) conditions. Mosquitoes were exposed to control untreated nets, nets treated with low dose (2.5–5.0 mg/m2 deltamethrin) or high dose (10.0–16.7 mg/m2 deltamethrin) after feeding on blood samples from gametocytaemic volunteers. The median of ambient temperature recorded during the experiments (25.3 °C) and ambient relative humidity (69.7%) was used as a cut-off to plot mosquito mortality charts
