New data about the Costa Rican aphid fauna (Hemiptera, Aphididae)

Abstract

Aphids were collected from 39 locations throughout Costa Rica, representing a wide altitudinal range, and from both crops and native plants. 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. This brings the total number of aphid species known from the country to 91, representing 77,8% of all the known species in Central America.
