Fig. 3From: Nutrition of host plants influence the infectivity of nucleopolyhedrovirus to polyphagous caterpillar, Hyphantria cuneaEnzyme responses of H. cunea larvae infected with HycuNPV on different host plants. A CAT activity; B PPO activity; C POD activity; D SOD activity. The asterisks represent significant differences between HycuNPV-challenged larvae and non-challenged larvae by GLM. *P < 0.05, **P < 0.001, NS, not significantBack to article page
