Hazard ratios of death relative to controls are predicted by the frequency of the pathogen alarm behavior (LOMs). Groups of 12 workers were challenged by brief immersion in the conidial suspensions of nine different strains of Metarhizium (for two colonies, n = 18). The strains corresponded with three different species. Open circles, M. brunneum; open squares, M. roberstsii; open triangles, M. guizhouense; solid circles, controls. The line of regression does not include controls. After controlling for colony effects, standardized β = −0.609, p = 0.008.
