Background: Anopheles stephensi is the primary vector of urban malaria in the Indian subcontinent and the Middle East, creating an emerging threat in Africa.
Methods: A new olive-green (olg) mutant has been identified and isolated from insectary colony strains of An. stephensi. Its body colour is highly prominent in 3rd and 4th-instar larvae and persists through the pupal stage.
Results: To determine the genetic basis of this mutant, crossing olg with wild type mosquitoes demonstrates that the olg gene is autosomal, recessive, and controlled by a single gene. The colour expression is uniform in both sexes.
Conclusion: This mutant can be used as a genetic marker and for genetic mapping in basic and applied genetic research. The olg mutation in the urban malaria vector can be used in advanced malaria research to better understand the genetics of this species.
