From: Queen quality, performance, and winter survival of imported and domestic honey bee queen stocks
Mean and 95% confidence intervals of 20,000 nonparametric bootstrapped estimates of honey bee winter colony survival for colonies headed by different queen stocks (A) (e.g., BC, HI and NZ) (Fig. S1) and (B) (e.g., domestic (i.e., BC queens) and imported (i.e., pooling HI and NZ queens). Different letters indicate significant variation in mean winter colony survival among queen stocks (N = 79) (Fig. S4).
