Fig. 6: Volatiles released by rice plants and effect on oviposition behavior of C. suppressalis females.
From: Cooperative herbivory between two important pests of rice

a Projection to latent structures-discriminant analysis (PLS-DA) of volatile emissions produced by rice plants that were either untreated (Control), infested by SSB, BPH, or both herbivores (SSB/BPH) for 48 h. The score plot display the grouping pattern according to the first two components and the ellipse defines the Hotelling’s T2 confidence interval (95%) for the observations. b Number of eggs laid by female C. suppressalis near or on filter paper that had been treated with volatiles collected from four types of differently treated rice plants. Exact P-values = 0.022 (Control vs SSB), 0.68 (Control vs BPH), 0.20 (Control vs SSB/BPH), <0.001 (SSB vs BPH), <0.001 (SSB vs SSB/BPH), and 0.82 (BPH vs SSB/BPH). Each bar represents the mean ± SE. Significance was determined by two-sided likelihood ratio test with generalized lineal mixed model (Poisson distribution error). Different letters above bars indicate significant differences between treatments (P < 0.05; n = 8).
