Relationship between temperature and Anopheles gambiae sensu lato mosquitoes' susceptibility to pyrethroids and expression of metabolic enzymes

Table 1 Number of An. gambiae s.l. mosquitoes from each rearing temperature regime used for biochemical analysis of metabolic enzyme level

Temperature regime (°C)	Mosquitoes that were not exposed to pyrethroids	Mosquitoes that were exposed to pyrethroids
25	50	40
28	50	16
30	50	28
32	50	40
34	40	–

NB: Few mosquitoes survived after exposure to pyrethroid insecticides, resulting in an unequal number of mosquitoes in the pyrethroid-exposed group; all mosquitoes exposed to insecticides at 34 °C died; hence there were no live insecticide-exposed mosquitoes to test from the 34 °C temperature regime
