Pistachio psylla, Agonoscena pistaciae Burckharat & Lauterer (Hem.: Psyllidae)΅ is the most important pest of pistachio orchards in Iran to reduce the quantity and quality of product. Several different insecticides have been used to control psylla by gardeners. For reduction of chemical insecticides using, the application of cocunat botanical soap (Palizin® SL70%, 1500, 2000, 2500 ppm) and acetamipride (Mospilan®, SP20%, 250 ppm), hexaflumuron (Consalt®, EC10%, 500 ppm), thiamethoxam (Memori®, SP20%, 400 ppm) were tested in the fields of Semnan, Khorasan-Razavi, Kerman and Qazvin regions, during 2013. The different concentrations of insecticides were sprayed over the whole canopy and fruits two times at spring and summer seasons. Based on the field studies, the efficiency, in 7 days after treatment, were recorded in the 1500, 2000 & 2500 ppm concentrations of palizin treatment by 69, 78 & 81%, recpectively, and in acetamipride, hexaflumuron and thiamethoxam insecticides by 73, 75 & 55%, recpectively. Also, the psylla oviposition was inihibited in the 1500, 2000 & 2500 ppm concentrations of palizin treatment by 72, 78 & 80%, recpectively, and in acetamipride, hexaflumuron and thiamethoxam insecticides by 73, 69 & 79%, recpectively. In addition, efficacy of different insecticides at 7 days after treatment, reaches the maximum and then decreases. Therefore, the cocunat botanical soap (Palizin®, 2000 ppm) spray over the whole canopy of pistachio trees could be used successfully to reduce psylla damage on pistachio.
