The ommon green lewing (Chrysoperl rne) is generlist pretor in most griulturl systems.

Fining effetive nturl enemies to use in ioontrol progrms nees to reognize their esirle hrteristis n these hrteristis re speifie through lortory, greenhouse n fiel exmintions [4]. One of the importnt hrteristis of nturl enemies in iologil progrms is their reproutive ttriutes [5]. One of the importnt ftors for the improvement of nturl enemies is ults' iet. Therefore, mny rtifiil iets hve een evlute for the rering of ult lewings not only ue to their ost effetiveness n esy preprtion ut lso their positive effets on the iologil prmeters of lewings ginst their nturl iets [6]. The effets of ifferent iet on iologil prmeters of this pretor hve een stuie y ifferent reserhers. Femle ults of green lewings require to free mino is to hieve the mximum feunity [7]. Pretors usully otin their foo requirements y the environment from the pollen n extrts of flowers [8, 9]. Finney [10] reporte tht when ommon green lewing fe only on honey, eggs li per femle n oviposition perio ws reue. Therefore, pretors were fe with Citrus melyug honeyew. Other reserhers use semi-rtifiil n rtifiil iet to fee ommon green lewing to inrese the feunity of femle ults n reue the osts of mss rering of this pretor [11, 12]. Rousset [13] reporte improve feunity y ing enzyme hyrolyze protein of yest to the iet of femle ults.

The presene of yest in ults' iet is neessry for egg proution, ut when only the yest ws use in their foo tretment, ults proue few eggs. The use of iet with yest n sugr is reommene to proue more eggs.

Mteril n Methos 2.1 Sitotrog erelell ulture Brley grins were isinfete y Phostoxin gssing tlets (ontin luminum phosphie, whih rets with norml tmospheri moisture to lierte phosphine (hyrogen phosphie) gs) n then ws poure into the ontiners (size = 10 20 30 m) n ws sterilize with oiling wter for 3 minutes n then ir rying until their wste re ompletely eliminte. In orer to eliminte the store grin mites n other potentil store pests, the grins of rley were kept 24 hours in the oven t the temperture of 65-67 C. Freshly li eggs of S. erelell (1-1.5 gr) were e to the per kilogrm of rley. After mixing n ing the eggs of grin moth to the rering ontiners, rely ontiners were kept in growth hmer of Plnt Protetion Deprtment of Mrgheh University (25 ± 1 C, 65± 5% RH n 16:8 h (L: D)). The emerging young lrve of S. erelell were fe on grins n ults were ollete fter 30 ys y spirtor in ontiners with fine polyester mesh (mesh size = 50).
