Background : Aedes aegypti is a mosquito which has high population in tropical countries. A. aegypti mosquitoes are main vectors of many tropical diseases such as Dengue Hemmoraghic Fever (DHF), yellow fever, zika, chikungunya, and others. Until now, the use of chemical insecticides remains as main choice and repetitive use could cause resistance, killing other non-target insects, as well as damaging the environment. Some plants are being developed as alternative biolarvacides for controlling the mosquitoes as vectors which are cheaper and have no hazard to humanity, including pandan wangi leaves (Pandanus amaryllifolius) and soursop leaves (Annona muricata Linn.)
Methods : This study is an experimental research with before and after intervention. The samples were A. aegypti larval instar III and IV as many as 10 animals per concentrate. The concentration of pandan wangi leaves and soursop leaves used were 0.5%, 1.0%, 1.5%, 2.0%, and 2.5% which was observed at 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, and 24 hours after exposure.
Results : Pandan wangi leaves extract at 2.0 % concentration and the soursop leaves at 1.0 % concentration causes 100 % lethal effect after 24 hours of exposure.
Conclusions: Pandan wangi leaves extract and soursop leaves extract have the potency as alternative biolarvacides. Soursop leaves extract shows better performance as alternative biolarvacide. |
