Rice Hispa

Symptom

The larval damage results in irregular white patches or streaks on the leaves. As these patches are translucent, the grubs and pupae inside can be detected by putting the leaf against the light. Adult scrape the chlorophyll from areas between the veins giving the characteristic appearance of white, parallel streaks along the main axis of the leaf. After feeding, the veins are affected, white blotches appear on the leaves. The affected leaves usually wither off. In severe infestations the leaves turn whitish and membranous and dry off. Severely damaged fields look burnt.
