Analysis of Volatile Metabolites from Papaya Seeds as Potential Organic Insecticides against Myzus persicae Sulz

Abstract

Myzus persicae is a toxic pest that acts as a limiting factor in increasing chili production in Indonesia. Symptoms of leaf curl are always found in every chili growing season along with the presence of these pests. In the field M.persicae controlled with chemical insecticides that trigger pest resistance. The aim of the study was to determine the effectiveness of papaya seed extract in controlling M. persicae , its effect on chili yields, and the content of volatile toxic compounds in papaya seeds which have potential as organic insecticides. Efficacy test in the form of 7 treatments, 5 replicates, namely application of papaya seed 10, 30, 50, 70, and 90 g/l. Analyzed data using analysis of variance with the F test and Duncan Multiple Range Test to determine the best treatment. Analysis of volatile metabolites was performed using Gas Chromatography-Mass Spectrometry to obtain specific metabolites. Papaya seed extract contains several volatile metabolites that act as organic insecticides, namely Heptasiloxane, 1,1,3,3, 5,5,7,7,9,9,11,11,13,13 tetradecamethyl compounds. The efficacy test in the field showed that papaya seed extract with a concentration of 50-70 g/l was able to suppress Myzus persicae attacks to the low attack category level, and increase chili production up to 2 times (100%). The use of papaya seed waste as an organic insecticide is in accordance with the concept of sustainable agriculture because it is environmentally friendly and improves food safety.
