Jatropha Curcas is getting value commercially as the demand of nonrenewable fuel sources increases significantly and also Jatropha is an eco-friendly energy plantation. Plantation of this plant is considered to be an excellent fuel replacement and it is likewise really economical compared to other fuels. Recently, Jatropha is facing some problem with insects and illness. The pests are classified into two ranges: Pest that affect young plants and Pest that impact developed plants.

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

Agrotis ipsilon: It is frequently known as Cut worm. This insect 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 pest can be managed by choosing the larva discovered around the plants or by mixing the bran, sawdust with insecticides.

Scarabaeid Beetle: This insect ruins the root of the young plant. Initially, the larva consumes the organic matters present in the soil and then concerns the root. The larva attack might eliminate the entire plant.

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

Army worm: Spodoptera litura existence can be determined by biting in the leaves. The severe infection might totally eliminate the plants.

Control: Insecticides are utilized to control the pests.

Grasshopper: This prevails insect found in numerous plants. Valanga nigricornis and Locusta migratoria extensively attacks the plant. The pest often 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 bug harms the Jatropha stem and it is commonly seen in Indonesia. The stem assaulted by this bug typically fall down. The existence can be identified by the larva penetration hole at the stem.

Control: The Insecticide typically used 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 pest can eat all the leaves of the plant simply put period. The quality and yield of the seeds get minimized due to the heavy attack.

Control: This can be controlled by picking 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 sensation when allowed 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 grows older.

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

Leaf Hopper: This bug is found mostly 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 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 bug existence can be determined when the leaf become yellow-colored, shrinks, turns red and fall down. The insect can likewise be spread through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a major bug which attacks the plant throughout bloom duration so the crop yield totally falls down. This bug is seen around the tropical region.

The poisonous enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The insects typically occurs attacks the plant in flowering season and this bug is seen extensively in tropical areas. The female bug 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 blooming season.
