Figure 2. Significant interactions between infection state and fly strain in the absence (A and B) and presence (C) of wasps.

Untransformed mean survival of Spiroplasma-infected and Spiroplasma-free flies. Each fly strain is represented by a different line color. A. Larva-to-adult fly survival (no. of emerging adult flies/number of initial fly larvae). B. Pupa-to-adult fly survival (no. of pupal cases/number of initial fly larvae). C. Fly adult emergence rate or proportion of total adults that resulted in adult flies (no. of emerging adult flies/total no. of emerging adults [flies + wasps]). (P-value: pseudo-likelihood ratio test “covtest” for fly strain in Spiroplasma-free flies only).
