A recent study in Spain has revealed the discovery of the pistachio psyllid, Agonoscena pistaciae, in fourteen municipalities across the country, raising concerns about its impact on the country's pistachio industry. This pest, originally from the Middle East and eastern Mediterranean, has so far been detected only on Pistacia terebinthus, not affecting Pistacia vera unless grafted. The researchers have highlighted the need for monitoring this pest to better understand its biology and potential control measures, given its history of causing significant damage in other pistachio-producing regions. The study also emphasizes the importance of correctly identifying this pest, which can be challenging due to its similarity to other species, to prevent overlooking the issue or inadvertently spreading it further.
