A genomic approach to inferring kinship reveals limited intergenerational dispersal in the yellow fever mosquito

摘要: Abstract Understanding past dispersal and breeding events can provide insight into ecology evolution, help inform conservation strategies the control of pest species. However, parent-offspring be difficult to investigate in rare species small such as mosquitoes. Here we develop a methodology for estimating from spatial distribution close kin, using pairwise kinship estimates derived genome-wide single nucleotide polymorphisms (SNPs). SNPs were scored 162 Aedes aegypti (yellow fever mosquito) collected eight close-set, high-rise apartment buildings an area Malaysia with high dengue incidence. We used reconstruct groups across three orders kinship. transformed geographical distances between all kin pairs within each category axial standard deviations these distances, then decomposed components representing events. Using components, isolated deviation dispersal. From this, estimated neighbourhood (129 m), median distance (75 oviposition radius gonotrophic cycle (36 m). also analysed genetic structure distance-based redundancy analysis linear regression, finding isolation by both buildings, size at 268 individuals. These findings indicate scale required suppress local outbreaks arboviral disease target releases modified mosquitoes mosquito control. Our is readily implementable studies other species, including pests significance.
