Abstract :In this study, it was tried to determine the amount of prey consumed by Chrysoperla carnea insert ignore into journalissuearticles values(Stephens); insert ignore into journalissuearticles values(Neuroptera: Chrysopidae); at varying prey densities and its potency in reducing the population of the pest. Aphids used as nutrients [Aphis fabae Scopoli and Acyrthosiphon pisum Harris insert ignore into journalissuearticles values(Hemiptera: Aphididae);] were given to each larval stage insert ignore into journalissuearticles values(InstarI, InstarII, InstarIII); of the predator in certain numbers insert ignore into journalissuearticles values(5, 10, 20, 40, 80, 160);. According to the data obtained, an increase in the amount of food consumed by C. carnea was observed depending on the food density given. The attack coefficient insert ignore into journalissuearticles values(a); and handling time insert ignore into journalissuearticles values(Th); were also calculated separately for each larval period. These values were 1.12 and 23.62 min, respectively, when the third stage larvae of the predator were fed with A. fabae; while these values were found to be 1.11 and 21.89 min, respectively, when fed with A. pisum.
