Abstract
Oviposition deterrent activity of three mosquito repellents namely diethyl phenyl acetamide DEPA diethyl benzamide DEB along with diethyl toluamide DEET was studied in the laboratory against Aedes aegypti A albopictus and Culex quinquefasciatus mosquitoes All the repellents evaluated at three log concentrations 01 001 and 0001 in comparison with control by dual choice method The oviposition response and oviposition activity index OAI was estimated by counting number of eggs laid in both the treatment and control Mean OAI determined for A aegypti was in the range of −023 to +022 −03 to +027 and +004 to +033 for DEPA DEET and DEB respectively whereas it was −077 to −0035 −092 to +0001 and −077 to −007 for A albopictus and −0927 to −0251 −1 to −041 and −094 to −017 for C quinquefasciatus The oviposition deterrent activity was observed in the order of DEET DEPA DEB Similarly the response of species toward the repellents as oviposition deterrent was in the trend of C quinquefasciatus A albopictus A aegypti The finding suggests potential role of mosquito repellents as oviposition deterrent
