Abstract


Laboratory studies were conducted to evaluate the effectiveness ofMonodora myristica in controlling the 3rd instar larvae of Aedes aegypti. Monodora myistica significantly reduced the populations of Aedes aegypti larvae (P<0.05). Application ofMonodora myristica hexanolic extract at 200ppmgave 70%mortalitywithin 1 hour of application and 100%mortalitywithin 24 hours of test period. There was a great reduction in potency of the extract when exposed to sunlight and U.V radiations.
