Differences between observed and estimated DI for each parasitoid assemblage and temperature (i.e. DIobs - DI0). Negative values translate to risk reduction, while positive values reflect risk enhancement for the host with multiple parasitoids. Light grey panel, two parasitoids conspecific; darker grey panel, two parasitoids heterospecific. Parasitoid abbreviations: A, Asobara sp.; L, Leptopilina sp.; and G, Ganaspis sp. Big dots represent the means (±s.e.) and small dots represent raw data. (Online version in colour.)
