Grasshopper: This is common bug found in numerous plants. Valanga nigricornis and Locusta migratoria widely assaults the plant. The insect often attacks the young plant.
Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.
Pest observed in mature plants:
Pest of Stem: Ostrinia furnacalis, Xyleborus spp.
Ostrinia furnacalis and Xyleborus: This bug damages the Jatropha stem and it is widely seen in Indonesia. The stem attacked by this bug generally drop. The presence can be identified by the larva penetration hole at the stem.
