Bacterial distribution on the fly-body surfaces
SEM imaging analysis of a 10-DPE fly body (A), and the body parts with microbes on the tarsal segments (panels B and C of 2-DPE flies; panels D and E of 10-DPE flies), leg junction area (F, arrowed in panel A), upper thorax (G), lower abdomen (H) and wing (I). After immersion of the 10-DPE flies in the spore suspension of B. bassiana, conidium (CO) germinated into different shapes with (J–L) or without (J) contacting bacterial cells (arrowed) 20 h posttreatment. Panels F-M are the 10-DPE fly parts with different microbes. Scale bars: (A) = 200 μm; (B–I) = 15 μm; (J–M) = 5 μm. (See also Table S1).
