American Armyworm infection has been observed in maize in Chitwan. Four to five farmers come to the District Agricultural Development Office daily with the problem of armyworms.

According to the horticulture development officer of the office, Swastika Chauhan, the infection of the American army worm has been observed in the corn planted in every area of ​​the district. "Since corn is planted here all the time, the armyworm infection has not stopped," she said, "this problem is seen in small and large corn plants." Maize is grown every twelve months in the

district. "Somewhere the corn is ripe and somewhere else they are planting . The attack of insects has increased due to the cultivation of regular maize and unseasonal maize,' Chauhan said, adding that the problem is increasing even though the land is not empty. She said that armyworm is also seen in rice, so it attacks maize crops every year.

The American armyworm is a nocturnal moth of the butterfly class . Its larvae eat and damage crops. Horticulture Development Officer Chauhan informed that insects that like corn crops damage rice, wheat, millet and other crops without eating corn. According to him, the larvae of this insect cause damage to corn leaves, pods and stalks. It affects the bud of corn in the early stage, and after the plant grows, it causes holes in the leaves and leaves.
