- Abstract
The study was conducted between 2008 and 2009 growing seasons at the cotton research institute of Nazilli in Aydın province. In the study, the population dynamics of Aphis gossypii Glov. and Asymmetrasca decedens and Empoasca decipiens Paoli were observed on nine cotton varieties which were harvested by the machine. During the two-year study, due to low amount of A. gossypii the population was not calculated. Therefore, population of Empoasca spp. was studied. During the study even the population of A. decedens and E. decipiens was under the economic injury level, the lowest population was observed on Lider variety followed by ST-468 and GSN 12 varieties. On the other hand, more populations were observed on Nazilli 954 and NAPA 122 varieties. Also, the highest yield was observed on Lider variety which has more hair density and low population amount. As a result, even the population was not reached to the economic injury level, the amount of the hair has impact on the population and should be useful against the insect in management.
