Figure 2: Expression of DsRed and EGFP in the high-permissive d17 strain and low-permissive p50 strain. Larvae (day 2 of the 5th instar) and pupae (day 2 of the pupae) were infected with BmNPV/polh-DsRed and BmNPV/ polh-EGFP at the amount of 2×104 pfu per larva and pupae. Photographs of the larvae and pupae were taken at 120 hpi. In each group of photographs, the top panels (A) exhibit bright light images and the bottom panels (B) show fluorescent images.
