is acquiring importance commercially as the need of fossil fuels increases enormously and also Jatropha is an eco-friendly energy plantation. Plantation of this plant is thought about to be an excellent fuel substitute and it is likewise really economical compared to other fuels. Recently, jatropha curcas is facing some problem with pests and illness. The insects are categorized into two varieties: Pest that impact young plants and Pest that affect developed plants.

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

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

Control: This insect can be controlled by picking the larva discovered around the plants or by blending the bran, sawdust with insecticides.

Scarabaeid Beetle: This bug destroys the root of the young plant. Initially, the larva consumes the raw materials present in the soil and then comes to the root. The larva attack may kill the entire 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 utilized to eliminate the insect.

Army worm: Spodoptera litura presence can be identified by biting in the leaves. The extreme infection might entirely eliminate the plants.

Control: Insecticides are used to manage the pests.

Grasshopper: This is common pest found in numerous plants. Valanga nigricornis and Locusta migratoria extensively assaults the plant. The insect typically 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 damages the Jatropha stem and it is extensively seen in Indonesia. The stem attacked by this insect usually fall down. The existence can be identified by the larva penetration hole at the stem.

Control: The Insecticide generally utilized to manage this pest 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 in other words period. The quality and yield of the seeds get reduced due to the heavy attack.

Control: This can be managed by choosing the old larvae around the surface and tossing away the assaulted leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning feeling when allowed to exposure to skin as it produces particular chemical substance. Initially the pest crowded in the leaf and then spread out all over the plant when it ages.

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

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

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

Mite: Mite also attacks the leaf and makes the whole plant weak. The bug presence can be recognized when the leaf become yellowish, shrinks, turns red and drop. The bug can likewise be spread out through fallen leaves.

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a serious bug which attacks the plant during bloom duration so the crop yield totally falls down. This insect is seen around the tropical area.

The poisonous enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The insects commonly happens attacks the plant in blooming season and this bug is seen widely 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 tips.

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