苹果绵蚜蚜小蜂发育历期、发育起点温度和有效积温的研究
本文以苹果绵蚜为繁殖寄主,研究了苹果绵蚜蚜小蜂在不同温度下的发育历期、发育起点温度和有效积温。结果显示：苹果绵蚜蚜小蜂的发育历期随温度的升高而缩短,最适发育温度为21℃-27℃。山东地区越冬代苹果绵蚜蚜小蜂打破滞育的发育起点温度为雌蜂8.58℃,雄蜂8.22℃;有效积温为雌蜂148.72日度,雄蜂154.68日度。非越冬代苹果绵蚜蚜小蜂在卵-羽化阶段发育起点温度为雌蜂5.62℃,雄蜂5.55℃;有效积温为雌蜂284.40日度,雄蜂为295.61日度。并推测了2008年济南地区苹果绵蚜蚜小蜂发生代数和越冬代羽化时间,与实测情况基本相符。...

| Bibliography: | Studies on developmental duration at different temperature,developmental threshold temperature and effective accumulated temperature of Aphelinus mali（ Haldeman） were carried out in the laboratory.The results showed that the developmental period of A. mali decreased as the temperature increased in the tested temperature range,and its developmental temperature was 21℃- 27℃. The developmental threshold temperature of overwintering generation female and male were 8. 58℃ and 8. 22℃ respectively,and the effective accumulated temperature were 148. 72 day-degrees and 154. 68 day-degrees respectively in Shandong. The developmental threshold temperature of non-overwintering generation at the stage immature,were 5. 62℃（ female） and 5. 55℃（ male）,respectively. The effective accumulated temperatures were284. 40 day-degrees（ female） and 295. 61 day-degrees（ male） respectively. We estimated the number of generations and the emergence period of A. mali in Jinan in 2008,which matched with actual situation. ZHOU Xian-Hong;LI G |
