  The common pistachio psyllid, Agonoscena pistaciae is a key pest of pistachio trees in Iran. Both adults and nymphs cause great economic damages by sucking sap and produce large amounts of honeydew. The continued use of pesticides to control A. pistaciae leads to resistant of its populations to several pesticides and inefficiencies in biological control, resulting in pest outbreaks.  In the present study, Field experiments were conducted during 2019–2020 on pistachio trees, the Ahmad Aghaei cultivar, in Kerman, Yazd, Qom, Khorasan Razavi, Khorasan Shomali, Khorasan Jonoubi, Semnan, Fars, Markazi, and Esfahan provinces to evaluate the effect of DG oil on A. pistaciae in comparison with the two pesticides Spirotetramat and Dinotefuran. The sampling was carried out a day before spraying and 1, 3, 7, 14, 21 and 28 days post-treatment. The experiments were conducted based on complete randomized blocks with four treatments (included the recommended dosage of DG oil (0.5 liter1000 liter water/ha), Spirotetramat (1 liter/1000 liter water/ha), Dinotefuran (0.75 kg/ 1000 liter water/ha and control (Spraying with water) and four replications. Results showed a high performance of DG oil starting from the first day after spraying and Continued for four weeks. Compared to Spirotetramat and Dinotofuran, DG oil had a suitable and satisfied performance. DG oil is recommended as the most environment-friendly and IPM compatible compound to control A. pistaciae.

  2 - Effects of ethanolic extracts of Rubia tinctorum, Ferula gummosa and Nesidiocoris tenuis (Hem.: Miridae) on sweet potato whitefly, Bemisia tabaci (Hem.: Aleyrodidae), and comparison with Spirotetrmat
  فاطمه Goroohi S. Imani M. A. Samih B. Panahi
  The efficiency of plant extracts of Rubia tinctorum L. (Rubiaceae) and Ferula gummosa Boiss(Apiaceae) and release of the mirid bug Nesidiocoris tenuis Reuter (Miridae) were compared with Espirotermat to control sweet potato whitefly, Bemisia tabaci Genn. (Hem: Aleyrodid More

  The efficiency of plant extracts of Rubia tinctorum L. (Rubiaceae) and Ferula gummosa Boiss(Apiaceae) and release of the mirid bug Nesidiocoris tenuis Reuter (Miridae) were compared with Espirotermat to control sweet potato whitefly, Bemisia tabaci Genn. (Hem: Aleyrodidae) in semi-field conditions. LC50 of plant extracts and pesticide for sweet potato whitefly was calculated. In the main experiment, plant extracts and pesticides were sprayed on tomato plants in cages covered with mesh fabric. LC50 values of pesticides and plant extracts were sprayed on plants. Nymph of mirids was hanged to plant tomatoes. Subsequent days after treatment, number of sweet potato whitefly was counted. The experiments were carried out at 25 ±5 °C, 50±5 RH and photoperiod of 16:8 h (L:D). LC50 of R. tinctorum and F. gummosa extracts as well as Espirotermat was 22.359, 45.641 and 0.404 mg/ml, respectively. Post density decreased R. tinctorum and F. gummosa extracts, Spirotermat and the mird bug 86.54, 83.73, 89.16 and 87.67 percent pf egg stage, 80.20, 76.28, 82.56 and 79.38 percent of nymphal stage, 80.66, 75.26, 85.89 and 81.86 percent of total immature stages as well as 81.89, 79.49, 84.85 and 81.98 of total nymphal stages. Findings from experiments could be promising for further studies on plant extract of Rubia tinctorum and the mirid bug as on alternative to chemical pesticides in natural conditions.

  3 - Effect of flupyradifurone, spirotetramat and thiacloprid insecticides on common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hem.: Psyllidae)

  Common pistachio psylla, Agonoscena pistaciae, is the most important pest of pistachio orchards in Iran and reduce the quantity and quality of the product. In this study, the effects of Flupyradifurone 0.5, 0.75 and 1 ml L-1, Spirotetramat and Thiacloprid 0.5 ml L-1 and More

  Common pistachio psylla, Agonoscena pistaciae, is the most important pest of pistachio orchards in Iran and reduce the quantity and quality of the product. In this study, the effects of Flupyradifurone 0.5, 0.75 and 1 ml L-1, Spirotetramat and Thiacloprid 0.5 ml L-1 and Flupyradifurone (0.5 ml L-1) with irrigation water were evaluated on nymphs and adult stages of A. pistaciae in Niriz region of Fars province. The number of nymphs and adult of A. pistaciae recorded in one day before until 3, 7, 10, 15, 20, 25, 30 and 40 days after chemical applications. The results showed that 3 days after treatment, different concentrations of Flupyradifurone and Thiacloprid have a good effect on the psyllid nymphs and the mean maximum of dead nymphs was in Thiacloprid. The mortality in Spirotetramat treatment on nymphs was increased in on the day 7 and the highest mortality occurred after 20 days. The mean number of the nymphs on treated trees with Flupyradifurone and Thiacloprid increased after 15 days of treatment. Efficacy of Spirotetramat increased after 7th day and the maximum efficacywas 99.44 percent on 20th day after treatment. The highest mean number of adult psyllid mortality was observed on day 3 after treatment in Flupyradifurone with concentration of 1 ml L-1.  The efficacy of Spirotetramat on adults increased after 10 days post-treatment and the highest was occurred on 30 day of sampling (98.23). The results showed that Spirotetramat was effective in decreasing of the pistachio psylla population after 40 days of the insecticide application. Manuscript profile
