Outline of Final Research Achievements |
Two sub-species (Aedes aegypti aepypti and Aedes aegypti formosus) of Aedes aegypti were found in all sampling sites in the southern African countries (Mozambique, Malawi, Zimbabwe and Zambia). The forest type (Aedes aegypti formosus) was dominated in the interior sites, while the urban type (Aedes aegypti aepypti) was dominated in the coastal area. In particular, the urban type was abundant in the northern Mozambique where a dengue outbreak was reported in 2014. When their genetic structures were compared among the urban type populations, the populations in the northern Mozambique were significantly different from the other populations. The findings from this study suggest that Ae. aegypti aegypti was responsible for the outbreak in the northern Mozambique, and the populations might have been introduced from other continents.
