Mortality of flies from different populations following exposure to Beauveria bassiana spores. African and non-African populations differ significantly (filled and open symbols respectively). Zimbabwe (filled diamonds), Kenya (filled triangles), Gabon A (filled circles), Gabon B (filled squares), Pennsylvania (open circles), Netherlands (open squares). Symbols are offset slightly to allow interpretation of error bars. The graph shows least squares means from mixed models together with standard errors.
