Abstract:
The basis of the present study was to distinguish the existence of any genetic
variability among populations of Culex quinquefasciatus which would be a valuable tool in
the management of mosquito control programmes. In the present study, population of Cx.
quinquefasciatus collected at different locations in Tamil Nadu were analyzed for their
genetic variation based on 28S rDNA D2 region nucleotide sequences. A high degree of
genetic polymorphism was detected in the sequences of D2 region of 28S rDNA on the
predicted secondary structures in spite of high nucleotide sequence similarity. The findings
based on secondary structure using rDNA sequences suggested the existence of a complex
genotypic diversity of Cx. quinquefasciatus population collected at different locations of
Tamil Nadu, India. This complexity in genetic diversity in a single mosquito population collected
at different locations is considered an important issue towards their influence and nature of
vector potential of these mosquitoes.
