| Abstract | ||||
| This study was carried out to study the biology and life table parameters of Duranta aphid, Aphis durantae Theobald under laboratory conditions throughout three different temperatures degrees (winter, spring and summer) during 2018 year. Data obtained showed that the spring season more suitable for A. durantae living (biology) more than winter and summer seasons, respectively. This showed clearly from life table's parameters which showed that the nymphal stages of A. durantae in spring season were less than in winter and summer, respectively. Also, life cycle, mean generation time, live 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. | ||||
