Control: Insecticides are used to manage the pests.

Grasshopper: This is common pest discovered in a number of plants. Valanga nigricornis and Locusta migratoria commonly assaults the plant. The pest 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 pest damages the jatropha curcas stem and it is widely seen in Indonesia. The stem attacked by this bug typically fall down. The existence can be recognized by the larva penetration hole at the stem.

Control: The Insecticide typically used to control this insect is carbofuran.

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

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

Control: This can be managed by choosing the old larvae around the surface area and throwing away the attacked leaves.
