In total, 48 species of aphids were identified, associated with 62 families and 111 species of plants, many of these representing new host plant records. Aphis nasturtii Kaltenbach, 1843 is reported here for the first time in Central America and Trichosiphonaphis (Xenomyzus) polygoni (van der Goot, 1917) for the first time in Costa Rica.
