Control: Insecticides are utilized to manage the pests.

Grasshopper: This prevails pest discovered in a number of plants. Valanga nigricornis and Locusta migratoria extensively assaults the plant. The pest typically 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 insect harms the Jatropha stem and it is commonly seen in Indonesia. The stem attacked by this insect typically drop. The existence can be determined by the larva penetration hole at the stem.

Control: The Insecticide generally used to manage this pest is carbofuran.

Pest of leaf: The typical 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 period. The quality and yield of the seeds get minimized due to the heavy attack.

Control: This can be controlled by choosing the old larvae around the surface area and discarding the attacked leaves.
