Abstarct: One of the major threats to pistachios is the pistachio psyllid, Agonoscena pistaciae, which is usually controlled by using chemical insecticides that cost a lot of currency to import every year. This study conducted two experiments in a 1000-square-meter plot of a pistachio orchard in Namen village in Sabzevar city. The first experiment compared four treatments: imidacloprid (Confidor), palizin, water and soap in two concentrations (0.5 and 1.5) plus distilled water (which served as control) to see how they affect the number of the eggs, nymphs and adults of the pest. The experiment used a randomized complete block design with three replications and seven treatments per block. The second experiment examined how the color (yellow, green, white and red) and the height (0.5 and 1.5 meters from the ground) of the cards mounted on pistachio trees affected nymph & adult counts separately. The results showed that all treatments significantly reduced the egg, nymph and adult pest mortality compared to control, but their effectiveness decreased over time until 21 and 28 days after spraying. The number of adults and nymphs also dropped on the 28th day due to the end of the psyllids' lifespan and lower oviposition. In the second experiment, the yellow cards attracted more nymphs and adults than the other colors, and it caught more insects after one week than after 48 hours. In both time periods, the total number of psyllids caught was significantly higher than the number of nymphs.
