摘　　要：在16,19,22,25,28和31℃恒温条件下以花卉一串红(Salvia splendens)饲养大戟长管蚜Macrosiphum euphorbiae(Thomas),测得该蚜虫的各龄历期和产仔前期,得出全若虫期的历期。依据有效积温法则计算的1～4龄若蚜和全若虫期的发育起点分别是12.5,7.8,10.3,4.1和9.3℃,有效积温分别是14.6,43.9,29.9,31.9和117.2日.度。大戟长管蚜适合生长发育的温度是19～28℃,最适合温度为25℃。Developmental duration of Macrosiphum euphorbiae（Thomas） was surveyed at constant temperatures of 16, 19, 22, 25, 28 and 31℃respectively. The developmental threshold temperature of 1 -4 instar nymphs and whole nymph stage are estimated to be 12.5, 7.8, 10.3, 4.1 and 9.3℃ respectively, and the effective accumulated temperatures for these stages are 14.6, 43.9, 29.9, 31.9 and 117.2 degree-day respectively. The suitable temperatures for M. euphorbiae range from 19℃ to 28℃ with the optimum temperature of 25℃ .
