Abstract: This study presents larvicidal effect of neem (Azadirachta indica) and karanja (Pongamia glabra) oil encapsulated calcium alginate beads (individuals and combination) against mosquito species (Aedes aegypti). Studies were conducted by combining these two oils with and without converting into alginate based encapsulation formulation. Combination (30% neem oil and 70% karanja oil) was found to be more effective then any other combination. The combination of neem and karanja oil recorded an LC50 of 3.1 g/l against A. aegypti. Mortality also increases in terms of concentration of active ingredients (20-77%) after 48 h. FTIR studies indicate that there is no chemical interaction between oils or oil and polymer.
