M. Raja, M. Suresh

Abstract: The housefly, Musca domestica L. , is a common vector of several bacteria, protozoan, and viral diseases. The botanical pesticides we evaluated the bioefficacy of crude extracts of sapindus emargintus against larvae of Musca domestica. The leaf extract of soapnut disrupt the activity of enzymes of larvae & pupae and inhibits the growth. The mortality was counted up to day 6. Hexane leaf extract of Sapindus emarginatus effective controlling the M. domestica. The percentage mortality rate of M. domestica larva when treated with different concentrations of hexane leaf extract shows the highest mortality 98.75 % was recorded in 2.0l/100ml. The chloroform leaf extract shows the highest mortality was recorded in 1.5l/100ml and 2.0l/100ml at 5th day and 100 % mortality found in 5th day and 6th day. The crude extract S. emarginatus will be the best alternative controlling of housefly larvae.
