Fig. 3. CA inhibitors decrease the pH inside the posterior midgut in adult Ae.
aegypti females. (A) Cresol Red added to mosquitoes treated with
104 mol l1 MTZ revealed a decrease in pH
(left) when compared to those not treated (right). (B) Thymol Blue added to
mosquitoes treated with 104 mol l1 MTZ
revealed a decrease in pH (left) when compared to those not treated (right).
However the effect was not as evident as observed with Cresol Red. Results
shown are representative of 10 treated and 10 untreated mosquitoes from
24 independent experiments.
