Feeding damage caused to lettuce by uninfected first instar larvae of H. virescens, or larvae infected with wild-type virus or AcJHE-KK. Thirty neonate larvae were infected per virus. A 50% reduction in feeding damage was seen for insects infected with AcJHE-KK relative to damage caused by insects infected the wild-type virus (PLSD = 0.588; P < 0.05).
