Jatropha Curcas is acquiring value commercially as the need of fossil fuels increases significantly and likewise Jatropha is an eco-friendly energy plantation. Plantation of this plant is thought about to be an exceptional fuel substitute and it is also very cost-effective compared to other fuels. Recently, jatropha curcas is facing some difficulty with insects and illness. The insects are classified into 2 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 typically called 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 area and this will diminished the plant totally.

Control: This insect can be managed by choosing the larva found around the plants or by blending the bran, sawdust with insecticides.

Scarabaeid Beetle: This bug ruins the root of the young plant. Initially, the larva takes in the organic matters present in the soil and after that pertains to the root. The larva attack might eliminate the entire plant.

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

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

Control: Insecticides are utilized to control the pests.

Grasshopper: This is common bug discovered in . Valanga nigricornis and Locusta migratoria widely attacks the plant. The bug often assaults the young plant.

Control: The insecticides used 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 curcas stem and it is commonly seen in Indonesia. The stem assaulted by this bug typically fall down. The presence can be determined by the larva penetration hole at the stem.

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

Pest of leaf: The typical pests 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 duration. The quality and yield of the seeds get minimized due to the heavy attack.

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

Needle Caterpillar: This caterpillar is covered with spines 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 after that spread out all over the plant when it ages.

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

Leaf Hopper: This bug is found primarily in tropical and subtropical regions. The bug targets the leaf and draws all the nutrients of the leaf and gets curls at the pointer. Later, the entire 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 entire plant weak. The bug existence can be determined when the leaf become yellowish, shrinks, reddens and fall down. The pest can also be spread through fallen leaves.

Control: Some preventive procedures can be done like correct 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 serious pest which attacks the plant throughout blossom duration so the crop yield entirely falls down. This pest is seen around the tropical area.

The toxic enzyme in the plant diminishes the entire plant.

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

Tip borer caterpillar: The pests typically takes place attacks the plant in blooming season and this insect is seen commonly 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 attacked seeds are suggested to burn. The insecticides like monocrotophos and bensultap are sprayed at the blooming season.
