Abstract

The common pistachio psyllid, Agonoscena pistaciae Burckhardt & Lauterer (Hem.: Aphalaridae), is one of the most important pests of pistachio trees in Iran and Middle East. Little is known about the morphological variation of the geographic populations of the common pistachio psyllid in Iran, especially in Kerman province as the main pistachio production province. In order to prepare more information on the morphological variation of this pest, different populations were collected from some main producing areas of pistachio in Iran, including Kerman and Khorasan Razavi provinces in 2016; and wing shape geometry of them was investigated using the geometric morphometric method. The results showed a significant difference in wing shape between the population of Khorasan Razavi Province and all of the populations from Kerman province. The results indicated a significant difference in the centroid size among the populations. Also, wing size was smaller in psyllid population from Ravar compared to other populations. Furthermore, narrower wing shape was found in psyllid populations from Khorasan Razavi province. In the studied populations, in spite of the allometric growth, significant shape differences still remain in constant size which may indicate the genetic basis of the variation rather than environmental factors. Moreover, links between morphological (in the present study) and molecular data (in the other studies) revealed.
