Within the framework of our study on biological method for controlling harmful insects, we aimed to investigate the types of diets for predator lacewing of Chrysopidae family in order to rear this insect under laboratory condition and choose both preys and artificial diet suitable for them. To archive the goal, such objectives as rearing of predator lacewing in laboratory condition, investigating both preys and artificial diets for both adult insects and larva, choosing the most suitable prey or diet and clarifying the effects of diet types on reproduction and development of lacewing were accomplished. Performing experiment to rear lacewing under suitable condition and investigate the diets of both adult lacewing and its larvae and selection of most suitable diet for them are main features of the present study.
