All United Nations reports indicate the importance of growing pistachio trees in the world from an economic point of view through statistical data issued by the World Food and Agriculture Organization (FAO), which clearly shows the increase in fruit production annually, after production at the end of the sixties of the last century was about 32 thousand tons And 100 thousand tons in the beginning of the eighties and a quarter of a million tons in the beginning of the nineties and a half million tons at the end of the twentieth century, and in 2018, the global production of pistachios was about 1.4 million tonnes, with Iran and the United States as leading producers, together accounting for 72% of the total . A 2020 report indicated that nearly half of the global production of pistachios in 2019 came from the United States, with production in Iran falling to as low as 7% due to US trade sanctions against Iran, climate change, and weak economic and water management in Iran.

The origin of the pistachio tree dates back to the Islamic Republic of Iran and is cultivated on large scales in warm or temperate climates and in sunny places, whether in clay, sandy, wet or dry soils, especially soils near grassroots or low acidity as they extend from Afghanistan to the Mediterranean and California According to the statistics of 2018, the Islamic Republic of Iran leads the world in the production of pistachios, with a total production of 551.307 tons, then followed by the United States of America, Turkey, China and the Syrian Arab Republic in the fifth rank, then Greece, Spain, Italy and Afghanistan and is cultivated abundantly in northern Iraq, especially the poor mountain areas and some areas within Mosul and Sinjar district.

Pistachios are infested with many insect pests. Kapnodis is one of the most dangerous enemies of these trees, as its larvae that live in the roots lead to the death of adult trees within a year or a little more.
