ABSTRACT
This study aimed to determine the feasibility of Anona squamosa leaves as an insect-repellent additive to sand-cast candle. To test for its effectiveness, the produced candle was tested on mosquitoes. Three trials were performed involving three different concentration of atis leaves proportions of the parrafin wax. The results of the test were recorded on a table using the One-Way Analysis of Variance, set at 0.05 alpha level of significance. The study hypothesized that there is no significant difference in the effectiveness among the different amounts of concentration of atis leaves in the sand cast candle in terms of the number of mosquitoes killed and driven way.
Results showed that atis leaves are feasible as an insect-repellant additive to sand-cast candle. The acrid principle,which is possessed by the leaves made it an effective insect-repellent.
