High-MMR bees show higher mite mortality than low-MMR when inoculated with Varroa.
Varroa inoculation increases bee mortality in high-MMR relative to low-MMR bees.
Mite load was lower in high- than in low-MMR bees when not inoculated with Nosema.
Similar mite load was found in high-MMR and low-MMR bees when Nosema inoculated.
Nosema inoculation reduces Varroa mortality in high-MMR bees.
