Jatropha Curcas is acquiring significance commercially as the need of nonrenewable fuel sources increases greatly and also jatropha curcas is an environment-friendly energy plantation. Plantation of this plant is thought about to be an outstanding fuel substitute and it is likewise extremely affordable compared to other fuels. Recently, Jatropha is facing some difficulty with bugs and diseases. The pests are classified into 2 varieties: Pest that affect young plants and Pest that impact developed plants.

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

Agrotis ipsilon: It is commonly called Cut worm. This pest impacts the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface and this will shrunk the plant entirely.

Control: This bug can be managed by selecting the larva found 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 consumes the raw materials present in the soil and then pertains to the root. The larva attack may eliminate the whole plant.

Control: The plant with good resistance power can get rid of the bug. For heavy attack, insecticides with components carbosulfan and carbofuran can be used to kill the pest.

Army worm: Spodoptera litura existence can be determined by biting in the leaves. The extreme infection could entirely kill the plants.

Control: Insecticides are utilized to control the pests.

Grasshopper: This is typical insect found in a number of plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The insect often 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 extensively seen in Indonesia. The stem attacked by this pest typically fall down. The presence can be determined by the larva penetration hole at the stem.

Control: The Insecticide generally used to control 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 duration. The quality and yield of the seeds get minimized due to the heavy attack.

Control: This can be managed by choosing 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 enabled to exposure to skin as it produces certain chemical substance. Initially the insect crowded in the leaf and then spread all over the plant when it ages.

Control: Manually, the pest can be eliminated just by soaking it in water or kerosene. The heavy attack can be managed by spraying organophosphate insecticides.

Leaf Hopper: This bug is discovered mainly in tropical and subtropical areas. The bug targets the leaf and draws all the nutrients of the leaf and gets curls at the pointer. Later, the entire leaf dry and pass away.

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 entire plant weak. The pest presence can be recognized when the leaf become yellowish, diminishes, turns red and drop. The insect can likewise be spread out through fallen leaves.

Control: Some preventive procedures can be simulated proper sanitation and burning the fallen leaves. Heavy attack can be treated 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 severe insect which attacks the plant during bloom period so the crop yield entirely drops. This pest is seen around the tropical region.

The harmful enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The insects commonly takes place attacks the plant in blooming season and this bug is seen extensively in tropical regions. The female pest laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant ideas.

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