Aphids associated with Lactuca (Asteraceae) in Iran with descriptions of two new species (Hemiptera: Aphididae).

A catalogue of aphid species associated with Lactuca (Asteraceae) in Iran is presented. Information has been gathered on 24 aphid species from nine genera collected on three Lactuca host plant species, including two new aphid species: Aphis lactucariae sp. nov. and Uroleucon favreti sp. nov. Additionally, 37 specific associations between aphid species and Lactuca plants were identified, including one new record for Iran and two new global records. Modifications to the key provided by Blackman & Eastop for aphid species living on Lactuca , and an identification key to the aphids associated with Lactuca in Iran are also provided.
