Jatropha Curcas is gaining importance commercially as the need of nonrenewable fuel sources increases significantly and also Jatropha is an environmentally friendly energy plantation. Plantation of this plant is thought about to be an exceptional fuel substitute and it is likewise extremely cost-effective compared to other fuels. Recently, Jatropha is facing some difficulty with insects and illness. The insects are classified into two varieties: Pest that affect young plants and Pest that impact developed plants.

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

Agrotis ipsilon: It is frequently called Cut worm. This bug 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 shrunk the plant entirely.

Control: This insect can be managed by choosing 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 concerns the root. The larva attack may kill the entire plant.

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

Army worm: Spodoptera litura existence can be determined by biting in the leaves. The serious infection could completely eliminate the plants.

Control: Insecticides are used to control the bugs.

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

Control: The Insecticide usually utilized to control this insect is carbofuran.

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

Leaf Caterpillar: This pest can consume all the leaves of the plant in short duration. The quality and yield of the seeds get reduced due to the heavy attack.

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

Needle Caterpillar: This caterpillar is covered with spines and produces a burning feeling when allowed to exposure to skin as it produces specific chemical substance. Initially the bug crowded in the leaf and then spread all over the plant when it ages.

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

Leaf Hopper: This bug is found mainly in tropical and subtropical regions. The pest targets the leaf and sucks all the nutrients of the leaf and gets curls at the suggestion. Later, the entire leaf dry and pass away.

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 pest existence can be identified when the leaf become yellow-colored, diminishes, turns red and drop. The insect can also be spread through fallen leaves.

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

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

Chrysocoris javanus, Tip borer caterpillar.

Stink Bug: Sting bug is a serious insect which attacks the plant during blossom duration so the crop yield completely drops. This insect is seen around the tropical region.

The harmful enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The bugs typically happens attacks the plant in blooming season and this insect is seen widely in tropical regions. The female bug laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant suggestions.

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