Abstract
Pomegranate (PunicagranatumL.) is an important fruit crop in Iran. Carob moth is the most important reason of pomegranate qualitative and quantitative reduction all over country. So this study was carried out in order to determine effect of using difference covers, including cover with 20×20 mesh (Harir), cover with 30×30 mesh (Behdashti), cover with 40×40 mesh (Metghal),for controlling of Ectomyelois Ceratoniae Zeller (Lepidoptera: Pyralidae). Furthermore, effects of different treatments on quality of fruit such as cracking, sunburn, total acidity, PH and total soluble solids were also determined. Results showed that in the studied orchard application of covers could reduce about 50% of total infection, in comparison with control treatment. There was no significant difference between the cover treatments in this case. Applications of Metghal cover was the best method for preventing sunburn in pomegranate fruits while that increased total acidity and decreased total soluble solids. Finally, we can propose using of cover for prevention and reduction of carob moth damaging and where sunburn is the important problem of pomegranate fruits, farmers can use the Metghal cover.
