This study was carried out to study the biology and life table parameters of Chrysanthemum aphid, Macrosiphoniella sanborni under laboratory conditions throughout three different temperatures degrees (winter, spring, and summer) during the 2018 year. Data obtained showed that the spring season more suitable for M. sanborni living (biology) more than winter and summer seasons, respectively. This showed clearly from the life table's parameters, which showed that the nymphal stages of M. sanborni in spring season were less than in winter and summer, respectively. Also, the life cycle, mean generation time, life span and longevity duration in spring season were less than in winter and summer seasons respectively. Lastly, the important parameter in the life table, intrinsic rate of increase (rm) in spring season was more than in winter and summer seasons, respectively.
