Effects of fly Spiroplasma-infection state and fly strain on length of developing wasp

Reduced model F ratio/Z value(df) P value
Fly strain (random) 0.94(n/a) 0.1737
Infection state (fixed) 146.74(1,108) <0.0001
Hours (fixed) 184.73(4,170) <0.0001
Infection state × hours (fixed) 36.74(4,169) <0.0001

Based on General Linear Mixed Model (GLMM). F = F ratio for fixed effects and corresponding degrees of freedom (subscripts in parenthesis). Z value from “covtest” for random effects. Boldface P values significant at α = 0.0001
