<br>Jatropha Curcas is getting value commercially as the demand of nonrenewable fuel sources increases enormously and also Jatropha is an environmentally friendly energy plantation. Plantation of this plant is thought about to be an excellent fuel replacement and it is also extremely economical compared to other fuels. Recently, Jatropha is facing some difficulty with bugs and diseases. The insects are classified into 2 ranges: Pest that impact young plants and Pest that impact grown plants.<br>
<br>Young plant insects: Cutworm, Scarabeid Beetle, Army worm, Grasshopper.<br>
<br>Agrotis ipsilon: It is commonly referred to as Cut worm. This insect affects the seedlings and young Jatropha plants. If the plant is impacted by the cutworm, the stem gets cut nearer to the soil surface and this will diminished the plant entirely.<br>
<br>Control: This bug can be managed by picking the larva found around the plants or by blending the bran, sawdust with insecticides.<br>
<br>Scarabaeid Beetle: This bug destroys the root of the young plant. Initially, the larva takes in the raw materials present in the soil and after that comes to the root. The larva attack might eliminate the entire plant.<br>
<br>Control: The plant with good resistance power can get rid of the insect. For heavy attack, insecticides with elements carbosulfan and carbofuran can be utilized to kill the pest.<br>
<br>Army worm: Spodoptera litura presence can be recognized by biting in the leaves. The extreme infection might entirely eliminate the plants.<br>
<br>Control: Insecticides are used to manage the bugs.<br>
<br>Grasshopper: This is typical insect found in numerous plants. Valanga nigricornis and Locusta migratoria commonly assaults the plant. The insect frequently attacks the young plant.<br>
<br>Control: The insecticides utilized betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.<br>
<br>Pest observed in mature plants:<br>
<br>Pest of Stem: Ostrinia furnacalis, Xyleborus spp.<br>
<br>Ostrinia furnacalis and Xyleborus: This insect damages the Jatropha stem and it is extensively seen in Indonesia. The stem attacked by this bug normally fall down. The existence can be identified by the larva penetration hole at the stem.<br>
<br>Control: The Insecticide normally utilized to manage this insect is carbofuran.<br>
<br>Pest of leaf: The typical bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.<br>
<br>Leaf Caterpillar: This insect can eat all the leaves of the plant in brief period. The quality and yield of the seeds get decreased due to the heavy attack.<br>
<br>Control: This can be managed by picking the old larvae around the surface area and discarding the attacked leaves.<br>
<br>Needle Caterpillar: This caterpillar is covered with spinal columns and produces a burning experience when allowed to call with skin as it produces particular chemical substance. Initially the pest crowded in the leaf and then spread out all over the plant when it ages.<br>
<br>Control: Manually, the bug can be killed only by soaking it in water or kerosene. The heavy attack can be controlled by spraying organophosphate insecticides.<br>
<br>Leaf Hopper: This pest 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 entire leaf dry and die.<br>
<br>Control: The heavy attack can be controlled by using insecticides like imidachloprid, beta cyfluthrin or carbosulfan.<br>
<br>Mite: Mite also attacks the leaf and makes the entire plant weak. The bug existence can be identified when the leaf ended up being yellowish, shrinks, turns red and drop. The insect can likewise be spread through fallen leaves.<br>
<br>Control: Some preventive procedures can be done like appropriate sanitation and burning the fallen leaves. Heavy attack can be dealt with by spraying insecticides.<br>
<br>Some awful insect which attacks flower and fruit are, Stink bug (Nezara viridula)<br>
<br>Chrysocoris javanus, Tip borer caterpillar.<br>
<br>Stink Bug: is a major pest which assaults the plant throughout bloom duration so the crop yield totally drops. This bug is seen around the tropical area.<br>
<br>The poisonous enzyme in the plant shrinks the entire plant.<br>
<br>Control: Insecticides recommended for this insect is chlorfluazuron, diflubenzuron, alfamethrin, and lamda cyhalothrin.<br>
<br>Tip borer caterpillar: The pests typically happens attacks the plant in blooming season and this bug is seen commonly in tropical areas. The female pest laid the eggs on the tender part of the plant and the young larvae feed the young fruits and plant tips.<br>
<br>Control: Manually, the attacked seeds are advised to burn. The insecticides like monocrotophos and bensultap are sprayed at the flowering season.<br>
