Percent of A. ervi larvae found in singly parasitized hosts and the percent of found larvae that were healthy in R-infected A. pisum vs. uninfected controls. Dissections were performed during the interval between 3 and 4 days and between 4 and 5 days. Significantly fewer larvae in R-infected aphids were healthy at 4–5 days; the remainder were dead or moribund. For R-infected aphids, n = 177 for 3–4 days and 223 for 4–5 days, whereas for uninfected aphids, n = 180 for 3–4 days and 215 for 4–5 days. ***, P < 0.001.
