Abstract

The potential of some plant crude extract against Lamprosema indicata was evaluated. The experiment was done by applying crude extract solution uniformly on Petridish and the larvae of L. indicata were released. The crude extract used in this study was obtained from Soxhlet extractor (acetone as solvent). The concentrations (treatments) of crude extract used were 0.25 and 0.5% (volume of extract/volume of water, v/v). The results showed that crude extracts affected insect mortality. Crude extract of Jatropha curcas (seed), Tagetes erecta (leaf) and Piper betle (leaf) at 0.5% concentration caused insect mortality up to 50%, whilst Annona muricata (seed), C. aurantifolia (peel), A. conyzoides (leaf,stem), C. nardus (leaf) and M. koenigii (leaf) caused insect mortality from 32.5 to 47.5%. The 0.25% crude extract concentration caused lower insect mortality
