Abstract: In perspective of its expanding interest, an endeavor was made in the present study to evaluate the larvicidal capability of essential Nagapattinam therapeutic plants like Pelargonium graveolens, Commiphora berryi and Ceiba pentandra against Aedes aegypti. Twenty five early third instar larvae of Ae. aegypti were exposed to various concentrations (50-250 ppm) and the LC50 and LC90 values of the P. graveolens, C. berryi and C. pentandra extracts was analysed by probit analysis. The oviposition deterrent activity was determined against Ae. aegypti to various concentrations ranning from 75-350 ppm under research facility conditions. The present examination revealed that the most elevated LC50 and LC90 values methanol concentrate of P. graveolens, C. berryi and C. pentandra against Ae. aegypti hatchlings were 112.01, 122.02 and 137.97 ppm, respectively and 205.97, 220.74 and 244.47 ppm, individually. Thus, the methanol extract of P. graveolens, C. berryi and C. pentandra showed 100%, 87.4% and 58.8% oviposition deterrent activity at 350 ppm concentration against Ae. aegypti adult females. The outcomes plainly demonstrate that most extreme larvicidal activity against Ae. aegypti was acquired with methanol concentrate of P. graveolens.
