The present studies were done in the BPT-5204 paddy field of Phulwarisharif Block of Patna District of Bihar. A fresh nursery field prepare for the sowing paddy seed for germination of paddy seedling. There was eradicated all types of grass like host plant for insect pest near the experimental site which was used for nursery germination. In this research work, it was investigated that nursery of paddy field infected by eggs of Scirpophaga incertulas
. It was find out that eggs were laid down on the blade side of nursery leaves. These eggs were carrying on in the paddy field during course of nursery plantation. It was find out that infected nursery show low strength during plantation in paddy field. Yield loss happen due to infestation in nursery field as well as in planted paddy field. A main symptom of this insect pest is dead heart of main shoot at vegetative growth and white ear or chaffy panicles at the ear head stage and reproductive stage of paddy.
