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


Agrotis ipsilon: It is commonly called 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 and this will shrunk the plant completely.


Control: This insect can be controlled by choosing the larva discovered around the plants or by mixing the bran, sawdust with insecticides.

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


Control: Insecticides are utilized to manage the pests.


Grasshopper: This prevails bug found in a number of plants. Valanga nigricornis and Locusta migratoria widely attacks the plant. The pest often attacks 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 bug damages the jatropha curcas stem and it is commonly seen in Indonesia. The stem assaulted by this pest typically drop. The presence can be determined by the larva penetration hole at the stem.


Control: The Insecticide typically used to manage this insect is carbofuran.


Pest of leaf: The common 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 simply put period. The quality and yield of the seeds get reduced due to the heavy attack.


Control: This can be managed by choosing the old larvae around the surface and throwing away the attacked leaves.

The poisonous enzyme in the plant shrinks the entire plant.


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


Tip borer caterpillar: The insects commonly occurs attacks the plant in blooming season and this insect is seen extensively in tropical regions. The female insect 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 advised to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.
