From: The use of Leaf Surface Contact Cues During Oviposition Explains Field Preferences in the Willow Sawfly Nematus oligospilus

Figure 6

Natural colonization and oviposition preference in six different commercial willow hybrids. (a) Field survey: Level of damage by defoliation (Number of plants damaged). It was estimated by using the following scale: L0 = no defoliation, L1 ≤ 5% defoliation, L2 = 5–25%, L3 = 25–50%, L4 = 50–75%, L5 = 75–100%. Friedman test P < 0.0001, *indicates significant differences by LSM multiple comparisons, N = 16 for each genotype. (b) Laboratory assays: David’s score calculated from an oviposition preference matrix for Nematus oligospilus on different commercial hybrids (N = 90 comparisons, Landau’s Linearity Index h = 0.97; P = 0.02, see matrix in Table S1).
