Résumé :
|
First detection of the blue alfalfa aphid, Acyrthosiphon kondoi Shinji, in Maryland is reported, including information on natural enemies and aphid biotype. Early reports of aphid outbreaks in Maryland were associated with the first detection of the blue alfalfa aphid during 1992. A number of natural enemies associated with pea aphid were observed attacking the blue alfalfa aphid. A biotype test indicated that the entries 'OK 51' and 'CUF-101' are tolerant to the aphid population, while 'Arc' and 'PA-1' are not. 'WL320', a common cultivar adapted for the mid-Atlantic states, was intermediate in tolerance.
