Control: Insecticides are used to control the bugs.

Grasshopper: This is typical insect found in numerous plants. Valanga nigricornis and Locusta migratoria widely attacks 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 bug 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 normally used to manage this insect is carbofuran.

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

Leaf Caterpillar: This insect 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 picking the old larvae around the surface and tossing away the assaulted leaves.
