Description
  • The parasitism of alfalfa aphids was determined during three crop growing seasons. The highest rates of parasitism of Acyrthosiphon pisum and Therioaphis trifolii occurred during the first-second and the fourth alfalfa inttercuts, respectively. The landscape surrounding the fields affected only parasitism rates of Ac.pisum. During the second intercut the forest area had a negative influence on parasitism rates, whereas the bordering surfaces of alfalfa and winter cereals had a positive influence. Correlations between the rates of parasitism and the rate of aphid populations were determined.Regulation of alfalfa aphids cannot be explained solely on the basis of one functional group of natural enemies.
