Supplement S4

Table S4 For all simulations with fixed number of parasitoids or fixed fraction of parasitoids the overdispersion parameter (Overdisp.) was estimated (no underdispersion allowed); anoverall F-test (df=12,30) for difference in response patternsbetween the five different simulation situations was performed and for each response category (Allee, competition, parasitism and survival) an F-test (df=4,30) was performed for difference between simulation situationss. For the values of the F test in bold the difference was significant (P<0.05).
