Molecular phylogenetics investigates the relationships between organisms. It employs a combination of molecular and statistical techniques to establish evolutionary links between living organisms or genes. The number of mutations/evolutionary events that have occurred between species since their divergence is referred to as genetic distance. The simplest method is to count the number of differences between two sequences. Genetic distance can be used to reconstruct population history. The primary goal of molecular phylogenetic research is to reconstruct the sequence of transformational events and represent them graphically in developmental trees that show links between species or genes over time. At the same time, The distance analysis method compares two aligned sequences and generates a matrix of all possible sequence pairs. For each comparison, the number of modifications (base substitutions and insertion/deletion events) is counted and expressed as a percentage of the overall sequence length. Pairwise distances are the most accurate estimates of the difference between all possible pairs of sequences. Mosquito vectors are thought to be among the deadliest animals on the planet. It is estimated that millions of people die as a result of mosquito-borne diseases (WHO 2020). Climate change has allowed invasive mosquito species that were previously restricted to the tropics and subtropics to spread poleward and establish mosquito Populations with the potential to spread pathogens that cause disease.
