 The successful implementation of new malaria control approaches requires a better understanding of male mating biology of the target mosquito species. This thesis explored the potential behavioural, ecological and genetic determinants of mating and gene flow in the major African malaria vector Anopheles gambiae s. l. It was observed that environmental factors, such as crowding and larval nutrition are important and can be manipulated in the laboratory to enhance male mating success. Given the successful establishment of a semi-field mosquito population and the evidence that it does maintain more genetic variation than laboratory colonies, it was  suggested that studies aimed at exploring male mating biology /ecology and feasibility of Sterile Insect Technique or Genetically Modified mosquitoes can be executed in an enclosed semi-field environment. The results of this thesis, therefore, provide useful information to strengthen current and future vector control approaches.
