Cnaphalocrocis medinalis

It is found in south-east Asia, including Hong Kong, Sri Lanka, Taiwan, Thailand and most of Australia.

Its larvae are recognized as pests of various crops, including Oryza sativa, Zea mays, and Triticum, Saccharum and Sorghum species.

The adult moth is characterized by its vibrant yellow or straw coloration, with distinct wavy lines visible on its forewings and hindwings.

A single caterpillar can damage numerous leaves, leading to reduced plant vigor and eventual crop yield loss, which can range from 10% to 50%.

Initially, they appear milky white, later transitioning to a yellow-brown hue with a visible black spot before hatching.

The 5th to 7th abdominal segments near the leading edge exhibit a single line of dark brown fine hair.

[2] Rice (Oryza sativa L.) is the most important staple food for more than half of the world population including India.

Insect pests inflict an average of 21%–51% yield loss in rice, which leads to one of the major reasons for poorer crop productivity in India.

[4] Because rice leaf roller has phototaxis, it has a strong tendency to approach metal halogen lamps, and farmers can use light to lure and kill pests.

[9] According to different generations, the use of pesticides should be reasonably arranged and used alternately to prevent the resistance of rice leaf roller.
