Maharashtra is highly infested by one of the most important arboviral disease i.e. dengue. Bionomics of the mosquitoes play a vital role in the development of their control measures. Outbreak of mosquito Borne diseases can be predicted by using entomological surveillance method and larval indices. Creating mosquito free and safe residential area needs creating management strategies and people cooperation. Hence the present investigation was carried to calculate the standardized larval indices tendency and the density of mosquito to determine the major breeding sources besides area of Mul talav, Tahsil Mul, District Chandrapur, Maharashtra. 

The study sites were personally visited both for indoor and outdoor water holding containers to identify the presence of mosquito’s larvae over a period of five months. The survey was conducted using health education and Waste prevention method. The most common species of the mosquitoes found during the study were Aedes egypti and Aedes albopictus. The larval indices like House index (HI), Container index (CI) Breteau index (BI) were calculated. Outcome of the study indicate that all the entomological indices were found to be above critical level during these months i.e. from August (CI=28.18%, HI= 31.58% and BI= 107.86%) to September (CI=26.12%, HI= 28.57% and BI=90.91%) but there is gradual decrease in mosquito density during the month of December (CI=18%, HI=7.89% BI=11.84%).
