  • a The correlations involving exclusively adults and/or uninfested pupae have 52 degrees of freedom, while those involving infested pupae and/or Varroa mites have 40 degrees of freedom. The correlations involving the mite infestation rates have 16 degrees of freedom. Correlations with associated P values of <0.01 or <0.001 are in boldface.
