Fig 6. Sex ratio of current-year (A) and 1-year-old (B) Altica brevicollis coryletorum beetles on shrubs growing in full light and shaded conditions over time. Numbers 1–7 (for current-year) and 1–10 (for 1-year-old) indicate successive dates of insect collection (see Materials and Methods).
One-way ANOVA was used to determine the effect of term (length of the sampling period) on current-year beetles (full light, R 2 = 0.2106, P = 0.4918; shade, R 2 = 0.0754, P = 0.9374) and 1-year-old beetles (full light, R 2 = 0.5475, P = 0.0018; shade, R 2 = 0.2715, P = 0.3076).
