Abstract

Codling moth, Cydia pomonella L. is the key pest of apple in Iran. Due to inefficiency of other control measures, insecticide application has been the first option, most common and successful management method so far. In this research, effect of Diflubenzoron (Dimilin® SC48) was compared with Phosalone (Zolone SE 35) and Thiaclopride(kalipso® SC480) in three regions of Zanjan, Urmia and Bojnord using a layout of RCBD with 4 replications for one growing season. Results showed that treatment of Dimilin.with 4.02±0.23, 7.26±1.4, and 2.6±0.42 percent of infection at Urmia, Zanjan and Bojnord recorded the least percent of infection respectively whereas treatment of control with 57.37±4.94, 45.21±3.3 and 57.12±3.08 percent of infection at the same experimental points recorded the highest percent. Treatment of Kalipso with 1.02±0.43 and 3.00±0.44 percent of infection at Urmia and Zanjan and treatment of Zolon at Urmia with 3.65±0.29 registered the same statistical group as the Dimilin. It could be concluded that current insecticides may be replaced by Dimilin per need.
