The toxicity of mixture of earring leaf and root extract (Acalypha indica L.) against Aedes aegypti mosquito larvae mortality

Abstract

Tropical regions such as Indonesia are known to have optimal conditions of humidity and temperature that are very conductive for the survival of insects, including the Aedes aeypti mosquito which contains the Dengue virus. Until now, people still use chemical control using chemically active larvicides such as temephos. The continued use of temephos can cause the mosquito vector to become resistant to the next generation and be harmful to the environment. One way to control vectors can be done biologically by using natural insecticides, a mixture of leaf and root extracts of the earrings plant (Acalypha indica L.). The study used a mixture of leaf and root extracts of the earrings (Acalypha indica L.) plant using 7 treatments consisting of 5 serial concentrations of 250ppm, 500ppm, 750ppm, 800ppm and 1000ppm, 1 positive control using Aedes and 1 negative control using Abate. The concentration that can kill 50% of Aedes aegypti larvae or (LC50) within 24 hours of exposure is 766,000ppm. The plants contain secondary metabolites such as alkaloids, flavonoids, triterpenoids and steroids which is toxic to the larvae of the Aedes aegypti mosquito.
