Abstract

Chemical insecticides that have been relied upon to control cabbage catterpillars have become the main cause of pest resistance, high residues in crop products and decreased biodiversity of natural enemies in the environment. Active ingredients of plants plays an important role in providing opportunities for the development of a plant extracts, particularly applied for agriculture using the organic extract as bioinsecticide. This paper reports the ethanolic leaves extraction of L. camara against the C. pavonana and S. litura larvae which are the main pest on cabbage plants in Indonesia. The objective of this research is to evaluate the antifidan performance of ethanolic leaves extract to C. pavonana and S. litura larvae. The extract was prepared by maceration and evaporation and followed by antifeedant bioassay test. The antifeedant test was used leaf disc deep method with choice and no choice test to find out the effective minimum concentration on feeding detterent activity. The mean leaf area consumed were analyzed by using non parametric statistics of Mann-Whitney U. The results showed that the antifeedant minimum effective concentration of ethanolic leaves extract L. camara to C. pavonana larvae at 2000 ppm (choice test) and 1000 ppm (no choice test) in consider as medium antifeedant categori, to S. litura larvae at 500 ppm (choice test) and performance antifeedant in consider as medium antifeedant categori.
