벼물바구미 피해정도에 따른 벼 생육 및 미질 변화에 미친 영향을 조사한 결과는 다음과 같다. 1. 벼물바구미 피해정도에 따라서 보면 피해정도가 심할수록 경수는 적고, 초장은 짧았으며 최고분벽기도 지연되었다. 2. 벼물바구미 피해에 의하여 출수기는 1-2일 정도 지연되었고, 간장도 짧아졌으며, 수수도 감소하였고, 등숙율은 떨어지는 경향이었다. 3. 벼물바구미 피해에 의하여 수량은 4-22% 감소하였으며, 그 정도는 1모작보다 2모작에서 심하였다. 4. 벼물바구미 피해에 의한 미질 변화는 불완전미가 증가하였고, 특히 청미가 증가하였다.

A field experiment was conducted to investigate the influence of water weevil damage on growth and grain guality in rice. Plant height was shortened, number of tillers per hill decreased and maximum tillering stage delayed in damaged field by rice water weevil. Heading date was delayed by 1-2days, culm lenght shortened, panicle lengthened, number of panicles decreaced, number of panicles per spikelet increased, ripened grain ratio decreased in damaged field by rice water weevil. Yield per 10a was decreased 4-22% in damaged field compared with that in undamaged field by rice water weevil, yield loss in late transplanting (June 23) was larger than that in early transplanting (May 20). Imperfect kerml rice, especially green kernel rice, was increased in damaged field by rice water weevil.
