Jatropha Curcas is getting importance commercially as the need of nonrenewable fuel sources increases enormously and also Jatropha is an environment-friendly energy plantation. Plantation of this plant is thought about to be an excellent fuel alternative and it is also very affordable compared to other fuels. Recently, Jatropha is dealing with some trouble with insects and illness. The bugs are classified into two varieties: Pest that impact young plants and Pest that impact matured plants.

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

Agrotis ipsilon: It is frequently known as Cut worm. This bug affects the seedlings and young jatropha curcas plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface and this will shrunk the plant totally.

Control: This pest can be controlled by choosing the larva discovered 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 consumes the raw materials present in the soil and then pertains to the root. The larva attack may eliminate the entire plant.

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

Army worm: Spodoptera litura existence can be identified by biting in the leaves. The severe infection could entirely eliminate the plants.

Control: Insecticides are utilized to control the insects.

Grasshopper: This is common pest found in several plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The insect frequently attacks 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 pest damages the Jatropha stem and it is widely seen in Indonesia. The stem assaulted by this pest generally fall down. The existence can be identified by the larva penetration hole at the stem.

Control: The Insecticide generally 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 insect can consume all the leaves of the plant simply put 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 getting rid of the attacked leaves.

Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning feeling when enabled to contact with skin as it produces particular chemical compound. Initially the pest crowded in the leaf and after that spread out all over the plant when it gets older.

Control: Manually, the bug 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 mostly in tropical and subtropical regions. The insect targets the leaf and draws all the nutrients of the leaf and gets curls at the suggestion. Later, the whole leaf dry and pass away.

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

Mite: Mite likewise attacks the leaf and makes the whole plant weak. The insect presence can be determined when the leaf ended up being yellow-colored, shrinks, turns red and drop. The insect can likewise be spread through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a serious bug which assaults the plant throughout bloom duration so the crop yield completely falls down. This pest is seen around the tropical region.

The poisonous enzyme in the plant shrinks the whole plant.

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

Tip borer caterpillar: The bugs typically happens attacks the plant in flowering season and this insect is seen widely 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 pointers.

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