Plantation of this plant is thought about to be an outstanding fuel alternative and it is also extremely affordable compared to other fuels. Recently, jatropha curcas is dealing with some difficulty with insects and diseases. The insects are classified into 2 varieties: Pest that impact young plants and Pest that affect developed plants.

Young plant bugs: Cutworm, Scarabeid Beetle, Army worm, Grasshopper.

Agrotis ipsilon: It is typically referred to 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 pest can be managed by choosing the larva discovered around the plants or by blending the bran, sawdust with insecticides.

Scarabaeid Beetle: This bug ruins the root of the young plant. Initially, the larva takes in the raw materials present in the soil and then comes to the root. The larva attack might kill the entire plant.

Control: The plant with great resistance power can get rid of the pest. For heavy attack, insecticides with elements carbosulfan and carbofuran can be utilized to kill the insect.

Army worm: Spodoptera litura presence can be recognized by biting in the leaves. The serious infection might totally kill the plants.

Control: Insecticides are used to control the insects.

Grasshopper: This is common insect discovered in numerous plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The pest typically 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 harms the jatropha curcas stem and it is extensively seen in Indonesia. The stem attacked by this insect typically fall down. The existence can be identified by the larva penetration hole at the stem.

Control: The Insecticide generally utilized to manage this bug is carbofuran.

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

Leaf Caterpillar: This insect can eat all the leaves of the plant in other words period. The quality and yield of the seeds get decreased due to the heavy attack.

Control: This can be controlled by selecting the old larvae around the surface area and tossing away the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning experience when permitted to call with skin as it produces specific chemical substance. Initially the insect crowded in the leaf and then spread all over the plant when it grows older.

Control: Manually, the pest can be killed only by soaking it in water or kerosene. The heavy attack can be controlled by spraying organophosphate insecticides.

Leaf Hopper: This bug is found primarily in tropical and subtropical regions. The insect targets the leaf and draws all the nutrients of the leaf and gets curls at the idea. Later, the entire leaf dry and die.

Control: The heavy attack can be managed by using insecticides like imidachloprid, beta cyfluthrin or carbosulfan.

Mite: Mite also assaults the leaf and makes the whole plant weak. The pest existence can be when the leaf become yellow-colored, diminishes, turns red and fall down. The bug can also be spread out through fallen leaves.

Control: Some preventive measures can be simulated proper sanitation and burning the fallen leaves. Heavy attack can be dealt with by spraying insecticides.

Some awful pest which attacks flower and fruit are, Stink bug (Nezara viridula)

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a major insect which attacks the plant during bloom period so the crop yield totally drops. This bug is seen around the tropical region.

The poisonous enzyme in the plant shrinks the entire plant.

Control: Insecticides recommended for this insect is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.

Tip borer caterpillar: The bugs frequently takes place attacks the plant in flowering season and this bug 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 pointers.

Control: Manually, the attacked seeds are recommended to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.
