Comparison of diversity indices of canopy predators in peach orchards with and without ground cover by <i>T</i>. <i>repens</i> (means ± SE).

Notes: Different letters in the same column indicate that the means are significantly different at P<0.05 (HSD test) within groups of ground cover (treatment) and bare ground (control) in Xinchang and Hudai during the three years (57 sample dates were considered as 57 replicates). Means of five diversity indices were calculated from a total of 30 trees per treatment or control.
