Harmful effects of rain water storage in sumps

If rain water is stored in sump, is there any possibility of breeding of dengue fever mosquitoes?

Mosquitoes spreading dengue are formed in water storage units. If rain water is stored in sumps there may be a chance for breeding of dengue mosquitoes. Dengue is a very dangerous virus resulting in death. Here in our area (Hosur, Krishnagiri District, Tamil Nadu) dengue is spreading fast. In our house I have made arrangements to collect the rainwater in sumps. But I afraid will there be any dengue mosquitoes here - please advise.
