ABSTRACT
Changes in the expression of genes were observed during development in populations of Anopheles (Anopheles) intermedius and Anopheles (Anopheles) mattogrossensis. Esterase showed seven zones of activity: EST1 was present in all developmental stages of both species; EST2 was observed only in larvae of A. intermedius and larvae and pupae of A. mattogrossensis, with greater activity in pupae; EST3 and EST5 were present in all development stages, with greater intensity in larvae; EST4 and EST6 showed weak activity in larvae of A. mattogrossensis and was not found in A. intermedius. Leucine aminopeptidase showed four zones of activity, of which LAP1 and LAP2 were found in all stages of A. intermedius, with highest activity in larvae, and in only of A. mattogrossensis. LAP3 was detected in all stages of A. mattogrossensis and in larvae only of A. intermedius. LAP4 was detected only in larvae and pupae of A. mattogrossensis, with greater intensity in pupae. Alpha-Glycerophosphate dehydrogenase showed a single zone of activity, detected in older fourth-instar larvae and becoming more intense from the pupal stage onwards.
