Control: Insecticides are used to control the insects.

Grasshopper: This prevails bug found in a number of plants. Valanga nigricornis and Locusta migratoria commonly assaults the plant. The bug often assaults 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.

Control: The Insecticide usually used to this pest is carbofuran.

Pest of leaf: The common pests 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 period. 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 area and throwing away the assaulted leaves.

Tip borer caterpillar: The insects typically happens attacks the plant in flowering season and this bug is seen extensively 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 ideas.

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