EFEKTIVITAS SERBUK BIJI PEPAYA (CARICA PAPAYA L. ) SEBAGAI LARVASIDA AEDES AEGYPTI

Abstract

The Aedes aegypti mosquito is the main vector of dengue fever. Repeated administration of chemical insecticides on insects can cause resistance and pose a health hazard. The solution can be achieved by using bioinsecticide-based natural materials such as papaya seed powder. West Sumatra Province in 2017 had a dbd pain (IR) rate of 46.42 per 100,000 population. Bukittinggi city is an area with a high prevalence of dengue cases in West Sumatra. In 2017 the most in Mandiangin Health Center (52.17%) Research aims to determine effectiveness with variations in concentration and time of using papaya seed powder as a larvacide. Research uses experimental methods (RAL methods) and Post Test Only Control Group Design. The study population is the larvae of the Aedes aegypti mosquito, a sample of the Aedes aegypti instar III mosquito larvae as many as 25 larvae per group. The study was conducted with differences in concentration and observation time with 7 treatments and 4 repeats, located at the Fort De Kock University Laboratory in June 2019. From the test results, it is known that the mortality rate of larvae as many as 25 larvae that died with the administration of papaya seed powder concentration of 1 gram for 18 hours. With a probit rate lc50 which is 1,393 grams and LC99 1,589 papaya seed powder. The results showed the greater the concentration, the higher the larval mortality rate. It is expected that papaya seed powder as a natural larvacide can be applied in life.
