Young plant insects: Cutworm, Scarabeid Beetle, Army worm, Grasshopper.
Agrotis ipsilon: It is commonly known as Cut worm. This bug impacts the seedlings and young jatropha curcas plants. If the plant is affected by the cutworm, the stem gets cut nearer to the soil surface area and this will diminished the plant entirely.
Control: This insect can be controlled by picking the larva found around the plants or by blending the bran, sawdust with insecticides.
Scarabaeid Beetle: This insect destroys the root of the young plant. Initially, the larva takes in the natural matters present in the soil and after that concerns the root. The larva attack might kill the entire plant.
Control: The plant with good resistance power can overcome the insect. For heavy attack, insecticides with parts carbosulfan and carbofuran can be used to kill the insect.
Army worm: Spodoptera litura existence can be determined by biting in the leaves. The severe infection might completely kill the plants.
Control: Insecticides are used to manage the insects.
Grasshopper: This is typical bug found in numerous plants. Valanga nigricornis and Locusta migratoria widely assaults the plant. The insect frequently attacks the young plant.
Control: The insecticides utilized betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.
Pest observed in mature plants:
Pest of Stem: Ostrinia furnacalis, Xyleborus spp.
Ostrinia furnacalis and Xyleborus: This pest harms the Jatropha stem and it is widely seen in Indonesia. The stem attacked by this insect generally drop. The presence can be determined by the larva penetration hole at the stem.
Control: The Insecticide generally utilized to control this bug 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 eat all the leaves of the plant simply put duration. The quality and yield of the seeds get minimized due to the heavy attack.

Chrysocoris javanus, Tip borer caterpillar.
Stink Bug: Sting bug is a major bug which assaults the plant throughout bloom period so the crop yield totally falls down. This pest is seen around the tropical region.
The toxic enzyme in the plant diminishes the entire plant.
Control: Insecticides suggested for this bug is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.
Tip borer caterpillar: The insects frequently takes place attacks the plant in flowering season and this pest is seen commonly in tropical regions. The female insect laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant ideas.
Control: Manually, the attacked seeds are suggested to burn. The insecticides like monocrotophos and bensultap are sprayed at the blooming season.
