Control: The plant with excellent resistance power can get rid of the insect. For heavy attack, insecticides with components carbosulfan and carbofuran can be used to eliminate the insect.
Army worm: Spodoptera litura presence can be determined by biting in the leaves. The serious infection could totally eliminate the plants.
Control: Insecticides are utilized to control the insects.
Grasshopper: This is typical insect found in numerous plants. Valanga nigricornis and Locusta migratoria widely assaults the plant. The bug often assaults 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 damages the jatropha curcas stem and it is widely seen in Indonesia. The stem attacked by this bug normally fall down. The presence can be determined by the larva penetration hole at the stem.
Control: The Insecticide generally used to manage this bug is carbofuran.
Pest of leaf: The common bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.
Leaf Caterpillar: This pest can eat all the leaves of the plant in other words duration. The quality and yield of the seeds get decreased due to the heavy attack.

Stink Bug: Sting bug is a serious bug which attacks the plant during bloom period so the crop yield entirely drops. This pest is seen around the tropical area.
The hazardous enzyme in the plant diminishes the whole plant.
Control: Insecticides recommended for this insect is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.
Tip borer caterpillar: The insects frequently takes place attacks the plant in blooming season and this insect is seen widely in tropical regions. The female bug laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant pointers.
