Evaluation of certain mosquito repellents marketed in India.

A study was carried out in certain villages of Distt. Ghaziabad (U.P.) to evaluate the efficacy of commercially available mosquito repellent preparations and devices. Results revealed that none of the repellents tested provided absolute protection against mosquito bites. The protection varied from 38 to 98% with different species of mosquitoes. In general, better protection was provided against Anopheles bite than against Culex. Of ten repellents evaluated. Mylol oil and Tortoise coils were marginally superior to Odomos cream and Rooster coils. Among electrical devices, Good Bye and Casper were marginally superior to Good Knight and Knight Queen.
