Effect of an increase in landscape variables (percentage of hardscape—HARD, honeylocust density—DEN, and tree species diversity index—DIV) on the abundance of honeylocust plant bug (HLPB), mimosa webworm (MWW), or honeylocust spider mite (HLSM) at 10-, 20-, and 100-m radius lengths surrounding honeylocust trees.
