چکیده

Darjeeling in West Bengal, India, is a part of the Himalayas biodiversity. Though mosquitoes are common to this region, they are restricted in their abundance in the rainy season. Previous surveys have revealed the presence of several culicine mosquito species including Aedes w-albus, and the predatory mosquitoes Toxorhynchites splendens from this region, and a few other dipteran species that dominate the detritivore trophic level of the aquatic insect communities. The mosquito larval habitats of this region include among others the cemented water storage tanks and bamboo groves. Immature stages of the mosquitoes Ae. aegypti were noted from a temporary water pool and a few bamboo stumps in and around Darjeeling. Though recorded from Gharwal region of Western Himalayas, the geographical limits of this vector were known to be restricted up to the foothills of Sikkim Himalayas. In another survey, this species was found to have restricted distribution upto the Eastern plains of Bihar and North Bengal. However, the observation of the immature stages of Ae. aegypti in Darjeeling prompted us to carry out a primary survey to confirm the extension of its geographical limits in India and the Himalayas in particular.
