Aphids associated with Carthamus in Iran with the description of the hitherto unknown male of Uroleucon carthami (Hille Ris Lambers, 1948) (Hemi.: Aphididae)

Aphids constitute a significant cohort of herbivorous insects, primarily nourishing themselves by extracting plant sap, sometimes posing a notable threat to plant health. Here, we present a comprehensive investigation into the aphid fauna associated with Carthamus in Iran, unveiling 18 species across 11 genera within the Aphididae. Furthermore, 31 associations between aphid species and host plants were recognized, of which two are new for Iran. Our study expands upon prior knowledge by documenting three new occurrences, shedding light on previously unrecorded aphid species in Isfahan and Razavi Khorasan provinces. In addition, we describe the previously unknown male of Uroleucon carthami, offering insights into its life cycle and reproductive strategies. An identification key to the apterous viviparous female aphids living on Carthamus in Iran is provided.
