Jatropha Curcas is gaining value commercially as the demand of nonrenewable fuel sources increases tremendously and also jatropha curcas is an environment-friendly energy plantation. Plantation of this plant is considered to be an excellent fuel replacement and it is also really cost-effective compared to other fuels. Recently, Jatropha is dealing with some problem with pests and diseases. The bugs are classified into two ranges: Pest that affect young plants and Pest that affect developed plants.

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

Agrotis ipsilon: It is frequently 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 shrunk the plant entirely.

Control: This pest can be managed by selecting the larva found around the plants or by mixing the bran, sawdust with insecticides.

Scarabaeid Beetle: This bug damages the root of the young plant. Initially, the larva takes in the organic matters present in the soil and then comes to the root. The larva attack may eliminate the entire plant.

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

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

Control: Insecticides are utilized to manage the pests.

Grasshopper: This is typical bug found in a number of plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The bug typically assaults the young plant.

Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.

Pest observed in fully grown plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Ostrinia furnacalis and Xyleborus: This bug harms the jatropha curcas stem and it is commonly seen in Indonesia. The stem assaulted by this bug generally drop. The presence can be recognized by the larva penetration hole at the stem.

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

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

Leaf Caterpillar: This pest can eat all the leaves of the plant in short duration. 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 and discarding the assaulted leaves.

Needle Caterpillar: This caterpillar is covered with spines and produces a burning sensation when enabled to exposure to skin as it produces particular chemical compound. Initially the bug crowded in the leaf and after that spread all over the plant when it gets older.

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

Leaf Hopper: This pest is found mainly in tropical and subtropical regions. The insect targets the leaf and sucks all the nutrients of the leaf and gets curls at the suggestion. Later, the entire 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 entire plant weak. The bug existence can be recognized when the leaf ended up being yellowish, shrinks, reddens and fall down. The insect can also be spread through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a severe bug which attacks the plant throughout bloom duration so the crop yield completely drops. This bug is seen around the tropical area.

The toxic 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 bugs commonly happens attacks the plant in flowering season and this insect is seen extensively in tropical regions. The female pest laid the eggs on the tender part of the plant and the young the young fruits and plant tips.

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