Population fluctuation of Acyrthosiphon pisum (Haris) (Homoptera:Aphididae) on different pea varietes under naturel conditions

In this study, carried out in the field of Çukurova Agricultural Research Institute, Dörtyol and Sumbas in years of 2006 and 2007, population dynamics of Pea Aphid, Acyrthosiphon pisum (Harris) (Homoptera; Aphididae) and the most preferable one in selected pea species for Pea Aphid were aimed to be determined. As a result of this study, while no difference was found in tested pea species in the point of Pea Aphid population, there were important differences between the locations, and the population level in Doğankent was higher than the other locations. But, the difference between population levels in Dörtyol and Sumbas was found not to be important. Also, there was a difference between the locations in the point of Pea Aphid?s emerging time. While the first generations were seen in the same time in Dörtyol and Sumbas, it was seen a month later in Doğankent. Key Words : Pea, Acyrthosiphon pisum, population
