| چکیده | ||
| The pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera, Psyllidae), is a significant pest that has caused considerable damage to pistachio trees worldwide. In this study, the effects of jasmonic acid (JA), potassium silicate (PS), and the combination of these compounds on the resistance of pistachio trees to A. pistaciae in 2020 and 2021 were investigated. The study found that the treatments had a significant impact on the nymphal period of the psyllid in both years. Additionally, the content of flavonoids was found to be considerably higher in the treated trees compared to the control. The highest nymphal period and the lowest survival rate of the psyllid were observed in trees treated with a combined application of JA and PS in both years. Furthermore, the study revealed that the levels of lipid and glycogen in A. pistaciae were the lowest when the psyllid was fed on trees treated with JA integrated with PS. In addition, the activity of peroxidase and esterase enzymes was found to be lowest in the JA+PS treatment. These findings suggest that the exogenous application of JA integrated with PS on pistachio trees can successfully suppress A. pistaciae population and can be considered in integrated management programs against psyllids. | ||
