摘要
通过对齐齐哈尔市玉米螟羽化开始早晚和持续时间与气象条件关系的分析,提出:6月平均最低气温的高低决定了玉米螟羽化开始的早晚,而玉米螟羽化开始的早晚和羽化持续时间的长短又影响着次年玉米螟的发生量和发生程度。
According to the investigation on the relationship between period of ostrinia furnacalis eclosion and meteorological factors during1993-2002in Qiqihar,Heilongjiang Province,it is indicated that the beginning time of eclosion is decided by average lowest temperature in June and that the beginning time and the length of time of ostrinia furnacalis eclosion will influence on the extent of Ostrinia furnacalis next year.
