Defensive responses of rice plants in response to oral secretion (OS) collected from Chilo suppressalis (SSB) larvae inoculated with Enterobacter. (A) Rice stem samples were harvested 48 h after mechanical wounding with application of OS collected from Enterobacter inoculated SSB larvae (OS+ Enterobacter) and OS collected from axenic larvae (OS−), and the levels of defense-related LOX enzymes were measured (F_(2,42) = 20.43, P < 0.001, n = 15). CK, untreated rice plants. B The 3rd instar larvae were allowed to feed on rice plants pre-treated by mechanical wounding with application of OS+ Enterobacter and OS- for 3 days, and then larval mass gain was determined (F_(2,113) = 54.83, P < 0.001; n = 38–40). CK, SSB larvae fed on untreated rice plants. Values are means ± SEM. Different letters above bars indicate statistically significant differences between treatments based on an ANOVA followed by LSD test (P < 0.05)
