Abstract
Mosquitoes are vectors of various diseases. To keep them away the convenient option are repellents. The repellents minimalize the contact with mosquitoes. The popular and commonly used mosquito repellant is DEET (N, N-diethyl-m-methylbenzamide). Though not much toxicity studies are reported of the usage of DEET, botanicals are always a safer option. Various crude drugs and methods are employed for repellant actions. In treatises of Ayurveda too, one can come across references of plants or compounds of various herbs used as repellants. One such combination is of chandana (Santalum album) and sarshapa (Brassica campestris). The essential oils of these two drugs have proved to have mosquito repellant action against Aedes aegypti. The study was conducted by Cone bioassay and Cage Bioassay methods. The repellency activity of Santalum album and Brassica campestris oil were tested at 0.5%, 1.0 %, 2.5 % and 5.0 % against 3-4 days old, blood starved female mosquito of Ae. aegypti. The synergistic activity for the essential oil, 7 hours knock down effect was noticed at the concentration of 5 %. Thus plant extracts could be a safer alternative as mosquito repellants.
