Abstract: Green leafhopper (Empoasca flavescens) is one of the main pests in orchards. In an experiment conducted in a peach orchard, sticky boards of 10 different colors were selected to lure E. flavescens. The results showed that the yellow sticky board had the best trapping effect, followed closely by the green sticky board, while the controlling effects of the light blue, purple and dark blue sticky boards were rather poor.All the sticky boards did some harm to the natural enemies of this pest insect, such as bees, spiders and ladybugs. Besides, other 5 species of pest insects were lured too. A comprehensive evaluation of ecological benefits of insect sticky boards of different colors showed that the yellow sticky board was the best, followed by the green sticky board.
