Jatropha Curcas is acquiring value commercially as the need of fossil fuels increases significantly and also jatropha curcas is an environment-friendly energy plantation. Plantation of this plant is considered to be an exceptional fuel replacement and it is likewise really economical compared to other fuels. Recently, Jatropha is dealing with some trouble with bugs and diseases. The bugs are classified into two varieties: Pest that affect young plants and Pest that affect matured plants.

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

Agrotis ipsilon: It is typically understood as Cut worm. This pest affects the seedlings and young jatropha curcas plants. If the plant is affected by the cutworm, the stem gets cut nearer to the soil surface and this will diminished the plant entirely.

Control: This insect can be managed by picking the larva found 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 raw materials present in the soil and then comes to the root. The larva attack may kill the entire plant.

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

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

Control: Insecticides are used to control the bugs.

Grasshopper: This is typical bug found in a number of plants. Valanga nigricornis and Locusta migratoria extensively assaults the plant. The pest typically assaults 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 curcas stem and it is extensively seen in Indonesia. The stem assaulted by this pest normally drop. The existence can be identified by the larva penetration hole at the stem.

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

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

Leaf Caterpillar: This insect can consume all the leaves of the plant in short period. The and yield of the seeds get minimized due to the heavy attack.

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

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning feeling when permitted to call with skin as it produces certain chemical substance. Initially the pest crowded in the leaf and then spread all over the plant when it gets older.

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

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

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

Mite: Mite also assaults the leaf and makes the entire plant weak. The bug existence can be recognized when the leaf ended up being yellow-colored, diminishes, turns red and fall down. The bug can also be spread through fallen leaves.

Control: Some preventive measures can be done like correct 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 major insect which assaults the plant during blossom period so the crop yield totally falls down. This bug is seen around the tropical area.

The harmful enzyme in the plant shrinks the whole plant.

Control: Insecticides recommended for this bug is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.

Tip borer caterpillar: The bugs typically occurs attacks the plant in blooming season and this insect is seen widely 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 attacked seeds are suggested to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.
