Abstract
Based on the data of rice injury caused by the first generation of striped rice borer(Chilo suppressalis (Walker)), which were collected in the three years from 1974 to 1976 in Sweon area, progress of the injury in relation to Degree Days was studied. Increase in the number of infested stems was strongly related to the dispersal features of larvae. The increase ceased at about 400 DD after modal emergence date when the larval distribution pattern became stable. The regression of the number of infested stems per infested hill on Degree Days was significant and the coefficients of determaination were 0.84 and 0.95 for 1974 and 1976, respectively. The regression coefficients in the two years were not statistically significant, suggesting a possibility for pre- diction of the mean number of infested stems per infested hill through a simple model.
제1화기 이화명나방에 의(依)한 수도피해(水稻被害)의 진전양상(進展樣相)을 파악하기 위하여 1974 년부터 1976 년까지 농촌진흥청 농업기술연구소 시험포장에서 수집된 자료(資料)를 분석(分析)하였다. 수도피해경수(水稻被害莖數)의 진전(進展)은 3령유충기(齡幼蟲期)를 전후(前後)로 유충(幼蟲)의 주내분산(株內分散)과 주내분산(株內分散)을 통(通)하여 일어나며, 유충분산(幼蟲分散)이 안정(安定)되는
