Larvicidal Activity of Piper nigrum, Pandanus amaryllifolius, Cymbopogon nardus, Cinnamomum burmanii and Azadirachta indica Herbs Extracts on Aedes aegypti Larvae

Abstract

Dengue fever is an endemic disease in Malaysia. Existing control measures are aimed at important species of mosquitoes that are focused on adult mosquitoes or mosquito larvae. Mosquito control is difficult when there are many factors such as resistance to insecticides used in mosquito control and causing health effects to non-target organisms. One way to combat dengue fever is to eliminate Aedes aegypti mosquitoes. One way is to use plant extracts as an additional insecticide as it has larvacidal potentials that contain different phytochemicals, especially in killing mosquito larvae without affecting other organisms and the environment. This study aimed to study the use of herbs in the control and prevention of the breeding of Aedes aegypti mosquito larvae. The study was conducted in the form of an experimental quasi study. The sample for this study was instar IV larvae of 10 larvae with 4 readings with a sample size of 240 larvae. Results of larval mortality analysis using herbal species using the Kruskal Wallis test showed that this value was smaller than the alpha value of 0.05. It can be concluded that there are related herbicides (Piper nigrum, Pandanus amaryllifolius, Cymbopogon nardus, Cinnamomum burmanii and Azadirachta indica) in the control and reproduction of Aedes aegypti mosquito larvae.
