This study was conducted to determine the difference in the effectiveness of the Kakawate (Gliricidia sepium) leaves and Bignay bark (Antidesma bunius) extracts as organic mosquito larvicide.The insecticidal and antimicrobial properties of Kakawate and Bignay as well as their abundance in Aklan have motivated the researches to conduct this investigatory project, to control if not eradicate the mosquitoes and protect the people from the risk of mosquito - transmitted diseases. The three treatments were 100 grams pounded Kakawate leaves, 50 grams pounded kakawate leaves extract and 50 grams bignay bark extract and 100 grams bignay bark extract. Treatment A, with 100% kakawate leaves is somewhat effective with 22.2% level. A level of 22.2% or moderately not effective is demonstrated by the treatment B, with mixture of 50% kakawate leaves and 50% bignay extract. Treatment C with the 100% bignay extract shows 11.1% level or somewhat not effective, mildly not effective and moderately not effective.It was demonstrated that Treatment A with 100% pounded kakawate leaves with mean of 5.33 and SD of 0.5774 is slightly acceptable. Treatment B with a Mixture of 50% kakawate and 50% bignay has mean of 8.33 and SD of 0.5574 shows unacceptable. Moreover, Treatment C with a mean of 7.00 with SD of 1.0 indicates mildly unacceptable.
