| Abstract | ||||
| The sweep net was used for studying the relationship between predators (Hippodamia convergens Guer.and Chrysopa carnea Stephens) and preys (Aphis faba Scopoli, Aphis gossypii Gloverand Myzus persicae Sulzer). Regular samples were collected weekly from Alfalfa at the two stations (A & B) in the two trapping years (March 2007- February 2009). The seasonal distributions showed that Hippodamia convergens Guer.,Chrysopa carnea Steph., Aphis faba Scopoli, Aphis gossypii Gloverand Myzus persicae Sulzer had three generations per year. The relationship between the activity of predators (H. convergens, C. carnea)and preys (A. faba, A. gossypii, M. persicae) explained that the more increasing in the predators the more decreasing in the population of the preys. | ||||
