  1. By investigation on the relationship between period, quantity, extend of ostrinia furnacalis emergence and meteorological factors in qiqihaer, this paper analyzes the factors which effect on period, quantity, extend of ostrinia furnacalis about annual wave. the beginning time of ostrinia furnacalis pupae emergence depends on average temperature in may and june, weather conditions in july decide whether ostrinia furnacalis pupae finish ahead of time ; the beginning time of eclosion is decided by average lowest temperature and precipitation in may and june, and the end time of eclosion is decided by average lowest temperature in june and july, meantime, the length of time of ostrinia furnacalis eclosion and time of grub emergence influence on the extent of ostrinia furnacalis. an important condition of a great emergence of ostrinia furnacalis is that how temperature matchs humidity, which substantially result in reduction of maize output

    本研究項目通過對齊齊哈爾市玉米螟發生期、發生量、發生程度與氣象條件關系的分析，找出玉米螟發生期、發生量、發生程度年際波動的影響因子： 5 、 6月的平均氣溫決定了玉米螟化蛹開始的早晚， 7月的天氣條件決定玉米螟化蛹是否提前結束； 5 、 6月的平均最低氣溫和降水則決定羽化開始的早晚， 6 、 7月的平均最低氣溫又決定了玉米螟羽化結束的早晚；而玉米螟羽化持續時間的長短和幼蟲發生的早晚影響了玉米螟的發生程度；溫濕條件配合適當與否是促使玉米螟大發生的重要條件，玉米螟大發生又會引起玉米的大幅度減產。
