Abstract

The mechanism of the organic pesticides of Bintaro plant extract (Cerbera manghas) in reducing the insect pest population needs to be continuously studied. The study aims to determine the Repelence (ability to resist) of bintaro plant extracts against brown ladybugs (Riptortus linearis). The factorial experiment with the first-factor treatment was extracted Bintaro plant organs, namely leaf extract, stem bark extract, fruit pulp extract and bintaro seed extract, while the second treatment factor was the extract concentration (w/v), namely a concentration of 2,5%, a concentration of 7,5%, and a concentration of 12,5%. The experimental variables were the chemical compound content of each Bintaro plant part extract, insect mortality, length of each instar and stadia, and development into the next instar or stadia. The research results showed that Bintaro plants (leaves, fruit, seeds and bark) contain ingredients that can be used as organic pesticides. Bintaro plant extract has an effect on the mortality and development of Riptortus linearis insects. The results of the Bintaro plant extract test on the mortality and development of Riptortus linearis insects are less significant if it will be used to suppress the population, but the application of organic pesticides in the field is proven to be able to suppress the population, reduce the level of crop damage and increase crop production.
