Pseudomonas protegens CHA0-gfp2 does not affect survival of Delia radicum, but it persists throughout different life stages. Five freshly hatched D. radicum larvae were added to cauliflower plants (four trays per treatment, each containing twelve pots) grown with P. protegens CHA0-gfp2 (CHA0) on the roots or without (control). a The pupation rate and the rate of flies emerging from pupae did not significantly differ between the control and the CHA0 treatment (p < 0.05; Mann–Whitney U test). Error bars depict standard deviations of the means of replicate trays. A repetition of the experiment is shown in Supplementary Figure S1. b Population sizes of P. protegens CHA0-gfp2 detected in D. radicum at different life stages after larvae fed on roots colonized by P. protegens CHA0-gfp2. No CHA0 was detected in individuals emerging from the control treatment (data not shown). Data are pooled from two experiments. Numbers above boxes indicate sample size. c Some flies in the CHA0 treatment exhibited morphological defects, e.g., crippled wings
