What is Brown leaf hopper in Brinjal
The brown leafhopper (Amrasca biguttula biguttula) is a major pest of brinjal (eggplant) in many parts of the world, including India. It is a small, wedge-shaped insect that is about 3 mm long and light brown in color. The nymphs are pale greenish and wingless. Both adults and nymphs suck the sap from the underside of brinjal leaves, causing them to yellow, curl, and stunt. In severe cases, the leaves may drop off and the plants may die. The brown leafhopper can also transmit the brinjal little leaf virus, which can further damage the plants.
