Aphis illinoisensis represents one of the most recent aphid invaders from the New World to the
Mediterranean Region. This aphid, which is native to North America and is now widely distributed
in Central and South America, was first found in Southern Turkey in 2002, and in 2005 it was also
found in Crete (Greece). Thereafter it was recorded from Northern Cyprus, Israel, Tunisia, Algeria,
Montenegro and Libya, and is now probably present throughout the Mediterranean. The present
work provides data on the presence of this aphid in the Maltese islands, a group of low-lying islands
situated in the central Mediterranean Basin.peer-reviewe
