STUDIES ON TWO SPECIES OF BLACK APHIDS (HOMOPTERA: APHIDIDAE) ON FABA BEAN AND NASTURTIUM1
Published online by Cambridge University Press: 31 May 2012
Abstract
Live cultures believed to be aphids of Aphis fabae Scopoli from New Brunswick, Manitoba, and British Columbia were compared by several methods. Cultures from British Columbia lived on faba bean, Vicia faba L., but not on garden nasturtium Tropaeolum majus L. Cultures from Manitoba lived on nasturtium but not on faba bean. Some of the aphids from New Brunswick lived on nasturtium only, and some on faba bean only. The aphids which live on faba bean are believed to be Aphis fabae, and those which will not live on faba bean are considered to be a distinct species.
