An inventory of the aphids (Hemiptera: Aphididae) from Cuernavaca, Morelos, Mexico.
An inventory was made of the aphids from Cuernavaca, Mexico, collected directly from cultivated and wild plants belonging to 58 families, between 1996 and 2002, by yellow water traps set within the surroundings of an experimental station between 1996 and 1997. Seventy-four species of aphids were identified which are included in 42 genera and seven subfamilies. The Aphidinae subfamily was best represented with 61 species, while Aphis was the genus with more species. Fifty-eight species are registered for the first time in Cuernavaca and 38 in Morelos. Aphis sedi, Ovatus mentharius, Takecallis arundinariae and Tinocallis saltans are new records for Mexico. An analysis is given according to the origin of the aphids, taking note that 60% of all collected species are introduced. The species richness observed was compared to those values recorded for other Mexican regions and tropical countries.
