Pomegranate fruit moth (PFM), Ectomyelois ceratoniae (Lep., Pyralidae), is one of the most important pests of pomegranate in Iran. The larvae of E. ceratoniae cause damage to pomegranate fruits. Several different methods including collecting and burning of infected fruits and biological control have been examined to control this pest, but these were not effective. One way that may prevent fruits infection is obstruction from laying eggs by the moth inside the fruit crown. In the present study, the effect of three types of fruit covers, including complete covering made by fabric net, crown covering with a plastic cap and crown covering with a cap made by fabric net on fruit infection rate were tested. The result showed that the mean infection rates were 9.50 and 2% for control and crown covering with a cap made by fabric net, respectively, so crown covering can reduce fruit damage by 78%. Comparison of flower and fruit drop, fruit cracking, cover stability and PFM infection indices between treatments indicated that using a cop made by fabric net on crown, in early May to early July, can be recommended for PFM control.  Manuscript profile

Pomegranate fruit moth (PFM), Ectomyelois ceratoniae Zeller (Lep.: Pyralidae), is the most important pest of pomegranate in Iran. The larvae of PFM damage pomegranate fruits. One way that may prevent fruits infection is obstruction from laying eggs by the moth inside the fruit crown. In the present study, the effect of crown covering time of pomegranate by fabric net, including different times of covering (2, 4 & 8 weeks after flowering) and number of covering stages on fruit infection rate were cpmpared in Kashmar and Garmsar regions, Iran in 2009. The result showed that the mean percentage of  infection were 11.70 in control and 3.50 and 2.80 for two and three stages of crown-covering, respectively. So the two and three stages of crown-covering reduced the fruit damage by 70 and 76%, respectively. Comparison of flower and fruit drop, cover stability and PFM infection indices among the treatments indicated that using two stages crown-covering with a cop made by fabric net, at 4 & 8 weeks after flowering (in early May to early July) can be recommended for PFM control.  Manuscript profile

Pomegranate fruit moth, Ectomylois ceratoniae Zeller (Lepidoptera: Pyralidae), is the most important factors for decreasing quality and quantity of pomegranate in Iran. Due to biology of the pest like egg laying place and larval feeding behavior, application of pesticide is not practical; consequently losses of this valuable product are too much. Application of Sterile Insect Technique (SIT) is a method that is used for a few insect with the special condition. This research has been done for evaluation practical control of this pest with application of nuclear methods. E. ceratoniae reared on the artificial diet (28±2ºC, 60±5% RH, 14 hours light and 10 hours darkness). Young and old pupa separated and were irradiated at different dose range of 0 (Control) and 40, 60, 80, 100, 120, 140, 160 Gy. The adults after eclosion crossed according to the following situations: Irradiated male×wild female, irradiated female×wild male, and irradiated male×irradiated female and wild male×wild female. The result shows that the best controlling formula of pomegranate fruit moth is irradiated males×irradiated females and the best controlling doses of young and old pupa are 120 and 160 Gy respectively.

Pomegranate fruit moth (PFM), Ectomyelois ceratoniae (Lep., Pyralidae), is the most important pest of pomegranate in Iran and other pomegranate producing countries. Because larvae feed inside the fruits, chemical control is not applicable. Several different methods including collecting and burning of infected fruits and biological control have been examined to control the pest, but none of them was effective. It has been recommended to prevent moths to lay eggs among stamens. In the present study, the effect of two methods of stamens elimination customary and hand-operating machine and application time were investigated in Saveh, a city of Iran. The result showed that the mean infection rates were 22 and 6% for control and 3 times stamens elimination by hand-operating machine, respectively. A comparison of flower and fruit dropping, fruit cracking and PFM infection indices indicated that using hand-operating machine could reduce fruit damage by 16%. It is concluded that stamens elimination by hand-operating machine in early June can be recommended. Manuscript profile

The pomegranate fruit moth, Ectomyelois ceratoniae Zeller, and quince moth, Euzophera bigella Zeller, are the major frugivorous pest. They cause qualitative and quantitative losses of pomegranate fruit. Sexual pheromone traps may provide a real estimation of adult emergence and flight activity periods, emigration and immigration of such pests. To fulfill such a purpose, an experiment was performed to observe the population fluctuation of E. ceratoniae and E. bigella using synthetic pheromone traps in pomegranate orchards of Tang-e-Siab Koohdasht (Lorestan, Iran), in 2011. Adults of E. ceratoniae and E. bigella appeared in late April and May, respectively, and their flights continued until mid November. These pests populations showed four and three flight peaks during the growth season, respectively. The quince moth's population was higher than on pomegranate fruit moth's population, while the peak of the moth flight was between late July to early August. So in the pomegranate orchards of Lorestan region, in addition to pomegranate fruit moth, quince moth is one of the important fruit pests. The quince moth appears a month later in comparison to pomegranate fruit moth and both are active until the end of the season. Manuscript profile

Pomegranate fruit moth (PFM), Ectomyelois ceratoniae (Lep., Pyralidae), is the most important pest of pomegranate in Iran. Application of the kaolin particle film (Sepidan® WP) might be an alternative for control of the pomegranate fruit moth and reduction of pomegranate sunburn. To assess the impact of kaolin on damage of pomegranate fruit moth, preliminary trials were conducted in the fields during spring to summer 2009 in Garmsar region of Iran. The different concentrations of kaolin (2.5, 5, 10 and 15%) were sprayed over the whole canopy and fruits four times at 4–5-week intervals from early May to early September. Based on the field studies, the infection rates of PFM were 9.3 and 2.4% for control and kaolin treatment (at 15% concentration), respectively. Sunburn damage of fruits was reduced in the kaolin WP-treated fruits. Also the result showed that, the flower & fruit drop, fruit cracking, aphids damage was reduced in kaolin treatments. Therefore, kaolin could be used successfully to reduce biotic and abiotic harmful agents on pomegranate. Manuscript profile

The pomegranate fruit moth (PFM), Ectomyelois ceratoniae (Lep.: Pyralidae), is the most important pest of pomegranate orchards in Iran. One way that may prevent fruits to be infected is the obstruction from laying eggs inside the fruit crown by the pest. In this study, the effect of twin usage of fruit stamen-removing (one and two stages) and kaolin spraying (3 & 5% concentrations of Sepidan® WP) were investigated during spring to summer of 2011 in Kashan region, Iran. The fruit cracking and PFM infection indices were calculated at the harvesting time on each tree. Considering the obtained results from the present research, kaolin treatment at 5% concentration and fruit stamens removing (two stages) treatment, reduced fruit damage by 85% in comparison with the control. Also, the result showed that, the fruit cracking was reduced in kaolin treatments, however no significant difference was observed in stamen-removing treatments. Consequently, twin usage of fruit stamens-removing in 2 stages and application of the kaolin at 5% concentration can be recommended for decreasing the PFM damage. Manuscript profile
