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。The results were showed as follows : the synthesis and uptake of vg of this parasitic wasp respectively initiated since the 10th and 13th day after parasitism, which were equivalent to the first pupal stage and the pharate adult stage of this parasitic wasp
