For each parasitoid species, proportions followed by the same letter are not significantly different (GLMs followed by a multicomparison test) and the proportions of the rearing host (A. pisum for A. abdominalis and A. ervi and B. brassicae for D. rapae) are indicated in italics. The most detected, accepted, and stung aphid species are indicated in bold text.

^aNo significant difference in the proportion of aphids detected by A. abdominalis among the species.
