Control: Insecticides are used to manage the insects.

Grasshopper: This is common pest found in numerous plants. Valanga nigricornis and Locusta migratoria commonly assaults the plant. The bug often attacks the young plant.

Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.

Pest observed in fully grown 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 pest generally drop. The existence can be recognized by the larva penetration hole at the stem.

Control: The Insecticide normally utilized to manage this pest is carbofuran.

Pest of leaf: The typical bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.

Leaf Caterpillar: This bug can consume all the leaves of the plant simply put period. The quality and yield of the seeds get reduced due to the heavy attack.

Control: This can be controlled by picking the old larvae around the surface and getting rid of the attacked leaves.
