Understanding the seasonal prevalence and biological parameters of mosquito Aedes albopictus (Skuse) are indispensable for population estimates, efficient vector control and dengue prevention tactics. The sampling of Ae. albopictus was completed through the collection of eggs, larvae, pupae and adults throughout the study seasons by use of nets and ovitraps at least once a week. Occurrence of Ae. albopictus was distinguished heterogeneously and populations were observed maximum in October post-monsoon season. The populations increased progressively from January-May and sharply deteriorated in June-July and September-November months revealing the highest breeding. However, the lowest density was observed during December-February. Growth of Ae. albopictus evaluated under standardized laboratory conditions with the provision of Balb/C mice as blood meal to adult mosquitoes, exhibited eggs hatching, and first, second, third and fourth instar larvae development in 3, 1.3, 1.2, 1.7 and 2.8 days, respectively. Nevertheless, pupation development, adult emergence, total life duration from egg hatching to adult emergence, male and female life spans persisted for 7, 3, 20, 25 and 30 days, respectively. Aedes albopictus accounted for 1% density of other mosquito genera collected (Culex and Anopheles), while, Aedes aegypti (L) was 3% abundant and indicated that both Aedes species had coexistence.
