Adaptation and variability of Aedes Aegypti in relation to food in the southermost fringe of its distribution - An interdisciplinary approach
Examensarbete (Master Thesis)
Aedes aegypti is the well-spread main vector of dengue and other viral diseases and in means of mosquito control, it is important to understand adaptation and variability within the species. This study has considered eggs of Ae. aegypti from two close regions in the area of Buenos Aires. The aim was to increase understanding in environmental and genetic characteristics in food intake. From a long-term perspective, this is a contribution to solving the issues of how modelling could take these factors into acount, in order to understand or predict adaptive trends and subsequently, permanent modifications in mosquito populations. The experiment was performed in collaboration with the Buenos Aires Mosquito Study Group (Faculty of Sciences, Buenos Aires University) and was outlined to obtain data of development times and wing-lengths of the subpopulations, when exposed to different diets. The subpopulations showed small differences in individuals all the way from egg to adult, depending on origin and differences in growth stratgies. hence, assumptions about homogeneity or uniformity within species, that are often made in mosuito control contexts, should be called into question.
