| Abstract: |
| The carob moth, Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae), is the most destructive pest of pomegranate, Punica granatum L., in Iran. The pest larvae feed inside the fruit and infested fruits its lose their quality, marketing and consumption utility. Pest chemical control is a total failure as the damaging stages are out of pesticides reach and seeking alternatives is highly in demand. For instance, trap cropping is an economic strategy in integrated pest management program. In this study, potential use of fig trees, Ficus carica L., as trap plant against E. ceratoniae was investigated in pomegranate orchards. For this propose, long term distribution pattern of the pest larvae was determined by GS+ software in pomegranate orchards with regard to fig tree coordination in Sirvan district, Ilam province, during 2016-2017. Results showed that the most density of the larvae was observed in pomegranate trees neighboring the fig trees and with increasing distance between fig and pomegranate trees, the larval density declined on pomegranate trees (5-300%). Therefore, the fig trees and their neighbor pomegranate trees can be treated as trap plants in the pomegranate orchards. By concentrating the control strategies, eg. mechanical pomegranate trees adjacent to the fig trees, efficacy of the control strategies for controlling the pest can be enhanced in pomegranate orchards. Therefore, results of the study can be used for developing integrated pest management program in pomegranate. |
