Jatropha jatropha curcas is gaining significance commercially as the need of fossil fuels increases significantly and also Jatropha is an environmentally friendly energy plantation. Plantation of this plant is thought about to be an excellent fuel substitute and it is also very cost-effective compared to other fuels. Recently, jatropha curcas is dealing with some problem with insects and illness. The insects are categorized into two varieties: Pest that affect young plants and Pest that impact grown plants.

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

Agrotis ipsilon: It is typically referred to as Cut worm. This bug affects the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets to the soil surface and this will shrunk the plant totally.

Control: This pest can be controlled by selecting 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 takes in the raw materials present in the soil and then concerns the root. The larva attack might kill the entire plant.

Control: The plant with great resistance power can conquer the bug. For heavy attack, insecticides with elements carbosulfan and carbofuran can be used to eliminate the insect.

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

Control: Insecticides are used to control the pests.

Grasshopper: This is typical bug discovered in numerous plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The bug frequently 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 widely seen in Indonesia. The stem assaulted by this bug usually drop. The presence can be identified by the larva penetration hole at the stem.

Control: The Insecticide generally utilized to control this pest is carbofuran.

Pest of leaf: The common 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 brief period. The quality and yield of the seeds get lowered due to the heavy attack.

Control: This can be controlled by choosing the old larvae around the surface area and discarding the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning feeling when allowed to contact with skin as it produces specific chemical substance. Initially the bug crowded in the leaf and then spread out all over the plant when it gets older.

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

Leaf Hopper: This pest is found mainly in tropical and subtropical areas. The pest targets the leaf and sucks 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 controlled by using insecticides like imidachloprid, beta cyfluthrin or carbosulfan.

Mite: Mite likewise attacks the leaf and makes the entire plant weak. The pest existence can be recognized when the leaf become yellow-colored, shrinks, reddens and fall down. The pest can also be spread out through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a severe bug which assaults the plant during bloom period so the crop yield completely falls down. This bug is seen around the tropical region.

The harmful enzyme in the plant shrinks the entire plant.

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

Tip borer caterpillar: The bugs typically occurs attacks the plant in flowering 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 suggestions.

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