Figure 1. Survival of pea aphids after injection of siRNA. The graph shows the number of surviving aphids at daily intervals after injection. Green line and open triangles: injections with siC002-RNA. Red line and closed triangles: injections with siGFP-RNA (control). Blue line and open squares: uninjected insects. For the siRNA-injected insects, the data points are averages from three experiments, each of which began with 12 insects in the experimental and control groups. The bars depict standard errors.
