Comparison of the effect of cutting off stamens of pomegranates and releasing Trichogramma embryophagum with Ectomyelois ceratoniae (Lep. pyrallidae) in Saveh region, Iran

Abstract :

A new species, Pomegranate (Punica granatum) is one of the most important crops in Iran. Markazi province has a lot of wide Pomegranate’s orchards. However, there are some pests that can damage these crops. Carob moth, Ectomyelois ceratoniae Zell. (Lep.: Pyralidae) is the most important pest, especially in Iran. The damage by this pest can at times reach up to 80%. To control it, three methods are used in Saveh region: a) Releasing the eggs of T. embryophagum for biological control of this pest.b) Cutting off stamens of pomegranate. c) Using the two methods together.The purpose of this research was to compare the efficiency of these three methods .To achieve this objective, a one-hectare-orchard was chosen for each treatment. The containing treatments: Releasing T. embryophagum, cutting off stamens of pomegranate, using the two methods together and control. Cutting off the stamens of pomegranate was done two times and the release of T. embryophagum was done10 times and once in every 10 days. Cutting off the stamens of pomegranate was done two times. 400 pomegranates were randomly picked out of each treatment (four repetitions of 100) and were kept for 2 months in the warehouse. The results of research showed that there was a significant difference between the treatments. Reduction of injury was observed in all of the treatments in comparison to the control. Infection amounts were 30% in control, 10.5% in releasing of T. embryophagum, 5.4% in cutting off the stamens of pomegranate and 4.5% in using the two methods together. There was no significant difference between cutting off the stamens of pomegranate and using the two methods together in the warehouse
