摘　　要：在12,15,18,21,24,27℃6个不同温度下,测定了麦长管蚜的个体发育和生殖力情况。结果表明,各龄期若虫发育的时间随温度的升高而缩短。用5种或5种以上温度组合测定发育始点(C)和有效积温(K),求得全若虫期的发育起点温度为6.1±0.7℃,有效积温常数为1098.3日度。而且,随着温度的升高,蚜虫的生殖力逐渐增大,此时曲线的峰值最大。The effect of temperature on development and fertility of individual Macrosiphum avenae(Fabri-cius) at 12 ,15,18,21,24,27℃ was studied in this paper.Every development stage of nymph cut down with ascending of temperature. C(Developmental threshold) and K(Effective accumutated temperature ) was determined by 5 kinds and more than 5 kinds temperature compose .C and K of whole nymph stage is 6.1±0.7 ℃ and 108.3℃. Fertility of Macrosiphum avenae is gradually increased with ascending of temperature.
