ABSTRACT

Essential oil from the leaves of Aegle marmelos was investigated for their larvicidal, ovicidal, adulticidal and repellent properties against Aedes aegypti and Culex quinquefasciatus. Essential oil was extracted from the fresh leaves by hydro distillation method. Different concentrations of the oil were applied against different developmental stages of both the mosquito species. The result of different bioassay showed various responses between the species. The essential oil showed higher efficacy as larvicidal and adulticidal agent against Cx. quinquefasciatus (LC50=121.88ppm against larva and 121.50ppm against adult at 72 hour exposure) while as ovicidal and repellent agent, the essential oil showed higher efficacy against Ae. aegypti with LC50 value 278.82ppm at 72 hour and 1 hour of protection time respectively. Therefore, it can be inferred that this essential oil is a potential one which could further be used as mosquitocidal agent against both the mosquito species. The GC-MS analysis revealed the presence of β- terpinyl acetate, 5- isopropenyl-2- methyl-7-oxabicyclo (4.1.0) hepten-2-ol and 2,3-pinanediol as major probable constituents of the oil which might play major role against insecticidal activities of the plant oil.
