在室内25℃条件下研究了7种不同抗性的春小麦品种(系)对麦长管蚜生长发育和繁殖的影响.结果表明,不同抗性品种(系)对麦长管蚜若蚜发育历期、存活率、成蚜寿命和生殖力有显著的影响。麦长管蚜在抗性强的品种上成蚜寿命短、产仔量少;以内禀增长率作为测定抗生性的指标,供试小麦品种(系)对麦长管蚜抗生性的大小依次为辽春10号〉02C-MB〉新春6号〉巴丰1号〉永良4号〉内麦19〉蒙花1号,与田间抗性鉴定结果基本相同.
Effects of seven varieties of spring wheat on the population parameters of Sitobion avenae (F.) were investigated at 25℃ in the laboratory. The results indicated that there were significant differences in the developmental duration, mortality of nymph aphids, the longevity and fecundity of adults. The adults had shorter longevity and poorer fecundity when reared with the leaves of higher resistant wheat varieties. The level of wheat resistance was in order of Liaochun 10 〉 02C-MB 〉 Xinchun 6 〉 Bafeng 1 〉 Yongliang 4 〉 Neimai 19 〉 Menghua 1 using the intrinsic rate of increase (rm) as an index of wheat antibiosis to aphids, which was correspondent well with that in fields.
