Background: Mosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control the current population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp.
Methods: The type of this study was post test only controlled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hours after the treatment and counted the number of larvae death. The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extract using Probit analysis.
Results: The results of data analysis in this study were the death rate percentage of larvae after 24 hours treatment was 0% in control, 44% in 0.25% extract, 52% in 0.50% extract, 60% in 0.75% extract, while in the extract group of 1%, the number of larval deaths was 72%. It obtained results with significant difference in some treatment groups that were concentrations of 0.25% - 1%. Probit analysis showed that LC50 was at 0.382% concentration.
Conclusion: From results of the study it can be concluded that jackfruit leaf extract (Artocarpus heterophyllus Lamk) was potential as Culex sp mosquito biolarvacide. So it is necessary to conduct further research on the effects of compounds that contained in other plant parts such as flowers, stems and roots which will be expected to have a function as biolarvasida.
