Fig. 1.

Relationship between mean parasitism rate per month and a mean species richness of natural enemies per month (F _1,13 = 5,83, P < 0.05) and b mean species richness of hosts per month (F _1,13 = 8.91, P < 0.05). The overall model with host and enemy richness was significant (F _{1, 13} = 4.86, r² = 0.46, P < 0.05). Residuals are taken after removing the effects for a host and b natural enemy species richness
