        The pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Aphalaridae), is the key pest of pistachio trees in Iran. The objective of this study was to field test, whether female or male of A. pistaciae attracted male or female pistachio psyllid in More
        The pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Aphalaridae), is the key pest of pistachio trees in Iran. The objective of this study was to field test, whether female or male of A. pistaciae attracted male or female pistachio psyllid in the fields. Sticky traps were used to assess whether traps with live male or female pistachio psyllid attract conspecific psyllid in the field. Traps contain 20 live females, traps contain 20 live males, or traps without male or female (control). We compared mean number of male or female psyllid to choose control, male or female baited traps. Results in year 2014 showed that the mean number of male attracted to control, male and female traps was 20.87±2.88, 24.20±3.72 and 25.80±3.38 psyllid, respectively. The mean number of female attracted to control, male and female traps was 20.93±3.11, 31.40±3.68 and 19.60±2.80 psyllid, respectively. Results in year 2015 showed that The mean number of male attracted to control, male and female traps was 54.13±9.11, 73.44±16.77 and 51.06±7.42 psyllid, respectively. The mean number of female attracted to control, male and female traps was 57.31±8.50, 93.13±19.79 and 54.06±10.23 psyllid, respectively. Results in year 2016 showed that the mean number of males attracted to control, male and female traps were 31.75±3.42, 29.00±4.42 and 45.00±3.16 psyllid, respectively. The mean number of female attracted to control, male and female traps was 31.44±3.45, 33.94±5.65.79 and 41.88±3 psyllid, respectively. This results can be useful for the development of more controlling methods for this pest. Manuscript profile

        Lobesia botrana (Lep., Tortricidae) is one of the most important pests of vineyards in Iran and the world. Sex pheromone plays an important role in tracking and controlling this pest and is inevitable to get the best time for spraying and prevent indiscriminate spraying. In this study, changes in the population density of grape-eating larvae and the peak time of insect flight in different generations of the species were investigated by installing pheromone traps in the garden of Kashmar Research Center in Khorasan Razavi province through 2020. In this study, four peak points of adult insect flight were recorded. The first flight peak was reached on April 15, and then reached the peak of the second flight with a decrease on June 3, and after this peak on July 7, the peak of the third flight occurred, and finally on September 5, the fourth peak of the flight was observed. After the last peak, due to the gradual decrease in temperature and lowering of the average temperature from the minimum thermal threshold, the flight activity of moths decreased and from mid-October onwards, the trap hunting stopped. The results also showed that the highest percentage of damage was related to the third generation and the lowest percentage of damage was related to the first generation L. botrana. It is recommended that the first specific spraying against grape clusters in the region for the second and third generations could be 5-7 days after the formation of the flight peak.

        3 - Investigation of presence, distribution, and adult insects flight period of some species of clearwing moths Synanthedon spp. (Lep.: Sesiidae) using pherpmone traps in Sanandaj city

        The family of Sesiidae includes about 1400 species in 150 genera. The larvae of these insects feed on the cambium of the tree and dry the tree. Using pheromone trap is one of the suitable methods for monitoring the pest in orchards. Therefore, in this study, the presence and distribution of clearwing moth were examined in the province, in 7 locations with an average distance of 20 km from each other in the city of Sanandaj using 6 pheromone traps in each region. Also in order to study the activity of the adult insects of different species of the mentioned insects in every 3 garden areas 6 traps (pheromone capsule containing two species Synanthedon myopaeformis (Borkhausen) (Lep.: Sesiidae) and Synanthedon tipuliformis (Clerck) (Lep.: Sesiidae)) were deployed that they were continuously (every 3 days) visited. The results showed that Synanthedon tabaniformis (Rott.) (Lep.: Sesiidae) species is present in all regions of trapping and the highest density of this pest is related to Qeshlagh dam garden (43 moths per  trap) (p< 0.05) and the S. tipuliformis species was observed in none of the trapping areas; also species of S. myopaeformis was observed in 3 regions at low concentrations. Studying the emergence period of S. tabaniformis adult insects showed that the first moths were trapped in the region of Qeshlagh dam garden in 2014/6/6, in the region of Salawat Abad in 2014/6/10, and in the region of Grize in 2014/6/13. The peak of the flight was observed in the two regions of Qeshlagh dam garden and Grize in 2014/6/23 and in the region of Salawat Abad in 2014/6/20. Finally, the last moths were trapped in the region of Grize in 2014/7/25, in the region of Salawat Abad in 2014/7/18 and in the region of Qeshlagh dam garden in 2014/7/21. Manuscript profile
