(a) Uninfected control; (b to h) larvae cultured with 18H at 1.0 (b), 0.5 (c), and 0.125 (d) mg/ml, 9E at 0.16 (e) and 0.08 (f) mg/ml, 9D at 1.0 mg/ml (g), and nonprotective 16H at 1.0 mg/ml (h). Arrows indicate plaques (c to g) or trails of dead cells (h). Bar represents 1 mm. Images were captured as described in Materials and Methods. A Power Macintosh 7200/120 computer and Adobe Photoshop 4.0 were used to prepare the figure.
