The increasing incidence of dengue in Malaysia highlights the need for effective and sustainable vector control strategies. Aedes albopictus is a major dengue vector widely distributed across urban and semi-urban areas; however, dengue incidence varies between localities despite its presence, possibly due to differences in the genetic composition of local mosquito populations. This study investigated the species identity and mitochondrial DNA sequence variation of Ae albopictus in Kuala Terengganu using an integrated morphological and molecular approach Adult mosquitoes were collected from a dengue hotspot area, Kg. Losong, and a low-incidence area, Universiti Malaysia Terengganu Species identification was initially performed based an morphological characteristics and subsequently confirmed by polymerase chain reaction (PCR) amplification of the mitochondrial cytochrome c oxidase subunit I (COX) gene. Initial PCR amplification produced double bonds, indicating non-specific amplification; therefore, the target fragment was excised and purified, yielding a single band of approximately 60 bp suitable for sequencing Sequence comparison and phylogenetic analysis showed that the Kuala Terengganu Ae. albopictus sequences clustered with Southeast Asian reference sequences, with no clear genetic differentiation observed between the two sampling sites. These findings indicate a genetically homogeneous Ae. albopictus population within the study area and provide baseline genetic information to support molecular surveilance and sustainable dengue vector control strategies in Malaysia.
