How to Identify Fall Army Worm Pests?

The larvae of the fall armyworm moth appear in green, olive, pale pink or brown colors and have four dark spots in each abdominal segment and three patterns down the back and nine in the abdominal segment arranged in a trapezoidal shape. There is a white structure shaped like an inverted Y in the English language between the eyes on the head.

What causes fall armyworm in maize?

It is mainly a pest of maize. The adult moth is a strong flying moth, which can fly over 100 km in search of host plants. It mainly eats the leaves including stems and cobs of maize. The main harmful stages are the larvae and adults. The larvae cut and chew all the green parts of the maize except the roots. On an average, maize production in 1 acre land area is approximately (20-25) quintals. But due to attack of fall armyworm its production reduces by (16-18) quintals i.e. production reduces by (20-30)%.
