↵x Both number of tunnels and number of dead beetles were expressed per dm2 of surface area, then as a percent distribution by section. Statistical analysis performed with arcsin of square root of proportion transformed data.
↵y Means within a column with no letters in common are significantly different by Fisher’s Protected LSD test at P=0.05.
↵z Only females attacked this section in a very low attack density.
