مطالعات مقدماتی مدیریت تلفیقی کنترل شپشک شفاف خرما Palmaspis phoenicis (Ramachandra Rao) 1922 در شهرستان طبس

Dates with a cultivated area of 1745 hectares and a production of 4665 tons yields is one of the most important agricultural products in Tabas in Southern Khorasan. The palm date green pit scale, Palmaspis phoenicis ( Asterolecanidae) feeds on palm dates and reduces crop quantity and deformes the fruits and leaves. This pest is the most important pest of dates on Kabakab cultivar in Tabas city. In order to achieve an effective and sustainable control program, in a garden with an approximate area of 4 hectares in Tabas city, which was planted from trees of the age of 6 years and Kababab cultivar, several plant based insecticides such as Tondexir, Palizin, Syrinol, Neem and Milkweed extract, was studied in combination with chemical pesticides. Initial measures included the pruning of of extera and infested leaves to reduce pest populations and better ventilation of the garden and reduce humidity by adjusting the irrigation system. Sampling of adult and nymph insects was carried out in each treatment, one day, 3 days, 7 days and 14 days after spraying. The population trend in all treatments was reduced during sampling. There was a significant difference between treatments of plant-based compounds at 1% level. The most effective in reducing pest population was treatment of Milkweed extract. Also, chemical pesticides including confidor and actara in irrigation water were investigated in order to absorption from roots. And foliage spraying with Deltametrin. As a result, plant based insecticides, in combination with other methods, had a satisfactory effect and severely reduced the pest populations. This method is recommended as a template for heavily infected gardens.
