Abstract: Dengue is an enigmatic vector-borne disease and is transmitted by the day feeding Aedes mosquitoes (Aedes albopictus and Aedes aegypti). Ae. albopictus is closely associated with human habitations and is adapted to feed on humans. The larvae of Ae. albopictus were collected from all kind of water filled container in and around the houses in two areas (Diamond Harbour and Canning) in South 24 Parganas, West Bengal. Larvae were taken to the laboratory and reared in colony culture cage. Morphological variations (maxillary palp, proboscis and wings) are observed from the emerged adults. These morphological variations may help to identify the vectors and its sibling species. The prevalence of such vectors may indicate the diseases (Dengue and Chikungunya) load present in that area. Re-emergence of Dengue, Dengue hemorrhagic fever (DHF) and Chikungunya in South 24 Parganas areas along with population abundance of Ae. albopictus has become a major health problem. Therefore, a preliminary attempt has been made to study the breeding habitat preference of Ae. albopictus along with its morphological variations in South 24 Parganas (Diamond Harbour, Canning). In our present study morphological variations such as cup shaped proboscis, white palp, mosaic palp etc. are observed. The frequency of variation in Ae. albopictus is 1.2%.
