Survival Analysis Larvacide of Fractionation Plant Seeds Soursop (Annona muricata L) Against Larvae of Aedes Aegypti Vector Dengue Haemorrhagic Fever

Abstract

Survival Analysis of a Natural Insecticide Seed Fractionation Soursop In larvae of Aedes aegypti vector of Dengue Haemorrhagic Fever in Manado City has done. This study aims to determine the most effective concentration of seed fractionation soursop (A. muricata) to kill mosquito larvae A. aegypti. The method used in extracting waste is soursop seeds by maceration with ethanol. Technical Data analysis was performed to find the concentration of deaths that affect the mortality of larvae of dengue mosquito A. aegypti instar III / IV with survival analysis methods. The test results show the MTTF or Mean Time To Failure (survival value) mosquito is the provision of 183 476 ppm concentration. Thus, the concentration of 183 476 ppm is a concentration of the most effective amount to kill mosquito larvae. According to toxicity criteria based Australian Petroleum Energy Association, 183 476 concentration of n-hexane extract fraction or soursop seeds (Mean (MTTF) = 183 476) at 24 hours of observation included in the criteria of Medium Toxicity (Moderately Toxic).
