Results of parasitoid functional group analysis showing the difference between organic and conventional farms in terms of total number of functional groups, and richness and diversity within functional groups. Data were analysed using a paired MANOVA. 10 pairs of organic and conventional farms (20 farms in total) were used in the analysis, with farming system as the treatment factor. All variables were log₁₀-transformed for analysis, but the range values shown are derived from untransformed data. Bold values indicate results that were significant at α = 0.05. Multivariate test, Wilks's λ = 0.358, p = 0.054. Adjusted univariate test α = 0.02.

	range organic	range conventional	F1,9	p
total functional group (total number of functional groups per farm)	5–12	6–11	4.09	0.074
functional group species richness (mean number of parasitoid species per functional group per farm)	1.85–4.15	1.77–3.15	6.17	0.035
functional group diversity (Shannon diversity index incorporating the number of functional groups and the number of species within each functional group)	1.31–2.13	1.37–1.96	9.35	0.014
