Figure 7. F-:G-actin ratio in Heliothis virescens hemoctyes. The ratio was determined by comparison of mean density of FITC-phalloidin staining to DNase I-rhodamine staining on a per cell basis at two focal distances in four treatment groups (see Fig. 6). Error bars are standard error of the mean, and different letters (z) and numbers (z+2.5µm) indicate means significantly differ at that focal distance at =0.05.
