Última Seasonal Abundance of Primary Parasitoids and Hyperparasitoids Associated with Acyrthosiphon pisum (Harris) and Acyrthosiphon kondoi Shinji (Homoptera: Aphididae) on Alfalfa OAK 妹尾, 望; 落合, 陽子; 仲島, 義貴. Seasonal abundance of primary parasitoids and hyperparasitoids associated with Acyrthosiphon spp. was studied in an alfalfa field in 2000. Two species of primary parasitoids were recorded: Aphidius ervi and Praon barbatum. Mean parasitism by A. ervi and P. barbatum peaked at 3.5% on 10 July and 13.0% on 29 June. Six species of hyperparasitoids were also collected. Rates of parasitism of A. ervi and P. barbatum reached over 90% and 80%, respectively. Dendrocerus carpenteri and Asaphes suspensus were the dominant species among hyperparasitoids.

Seasonal abundance and within-plant distribution of Acyrthosiphon spp. and their natural enemies were investigated on alfalfa in Obihiro, Hokkaido, Japan in 2001. Densities of A. pisum and A. kondoi peaked in early June. Coccinellid and syrphid predators appeared to respond to aphid numbers and were synchronized with aphid populations. Two species of braconid (aphidiine) parasitoids (Aphidius ervi and Praon barbatum) were collected. Parasitism rates for each aphid species were variable through the season, but the estimated number of parasitized aphids reached a peak at the same time as overall aphid densities. After the first harvesting of alfalfa (14 June) aphid densities became very low, and coccinellid and syrphid predators were not found. In contrast...
