Abstract

Biopesticides is still being developed to support integrated plant protection (IPM). Based on this, one laboratory study was conducted to measure the toxicity of Jatropha curcas L. to three main (major) pests in Indonesia, namely rice stink bugs (Leptocorisa acuta L.), army warms (Spodoptera litura) and Plutella xylostella. The study was also aimed at knowing whether the crude extract of fruit of Jatropha curcas L. had oral and dermal toxicity to the tested insects by doing three sets of experiment. The first set one used adult L. acuta, the second one used larvae of S. litura and the third one used larvae of P. xylostella. All experimental units coming from 6 treatments (concentrations ranging from 0 ml/l as control to 25 ml/l) and 4 replications were arranged in randomized completely design. The first and second sets used insect-dip bioassay method while the third one used leaf-dip bioassay method. Result of the experiment showed that fruit extract of Jatropha curcas L. had dermal toxicity indicated by killing 87,50% of L. acuta and 82,50% of S. litura tested. The fruits extract also performed as oral (stomach) toxin indicated by its capable of killing 95,00% larvae of P. xylostella tested. Key word: Jatropha curcas L., Leptocorisa acuta, Spodoptera litura, Plutella xylostella, toxicity
