Abstract

The paper presents the description of 24 newly established species of aphids in Croatia that have been collected and determined during the three-year research (1996-98) using the following methods: Rothamsted suction trap (RST) and yellow water trap (YWT). Out of the 24 species, the following 11 species were collected and determined by IGRC BARČIĆ in the 80's (the determinations have not been published) and were also observed in this study: Capitophorus horni, Cavariella theobaldi, Elatobium abietinum, Megourella purpurea, Microlophium carnosum, Pterocallis alni, Uroleucon tussilaginus, Chaitophorus leucomelas, Eriosoma ulmi, Thelaxes dryophylla and Tuberculatus querceus. The following 13 species of aphids have been collected and determined for the first time in Croatia: Hyperomyzus lampsanae, Macrosiphum gei, Callipterinella callipterus, Callipterinella minutissima, Tinocallis platani, Tuberculatus moerickei, Chaitophorus populeti, Periphyllus californiensis, Drepanosiphum aceris, Drepanosiphum acerinum, Drepanosiphum dixoni, Hormaphis betulae and Eulachnus sp. The 24 aphid species have been classified into one family, 8 subfamilies, 6 tribes and 19 genera. According to domination, the species were marked as eudominant, dominant, subdominant, recent or subrecent, while, according to the frequency of their occurrence, they have been marked as euconstant, constant, accessory or accidental.
