XIV International Entomophagous Insects Workshop - Jun. 11-15, 2006, Newark, Delaware, U.S.A.
Abstract: A survey of parasitoids of three clones of Myzus persicae (green peach aphid) and a clone of Aulacorthum solani (foxglove) on peppers in the lower Fraser valley of British Columbia, Canada from April - August 2005 revealed the presence of nine primary parasitoids. Aphidius matricariae was the dominant primary parasitoid species in all months, at all locations, and on all clones. Appearance of parasitoid species varied among parasitoid genera with some parasitoids occurring earlier in the season and others late in the season. Generally sex ratios were male-biased at the beginning of the season but as the season progressed, there was a shift towards a female-biased sex ratio. Hyperparasitoids were collected from three genera of hyperparasitoids, and were most common in the field in July and August.
