Abstract: Yellow sticky board trapping is an important physical control technology, which is widely used in the prevention and control of fruit tree pests. In order to ascertain the ecological benefits of using yellow sticky boards in pear orchards, experiments were conducted in two pear orchards, one of sod culture and the other of clean tillage. The results showed that insects of 73 families in 7 orders were trapped by the yellow sticky boards; that the number of insect species in both orchards showed a single-peak trend with the change of months; that the number of insects in the sod culture pear orchard was greater than that in the clean-tillage pear orchard; that the ecological benefits of yellow sticky board trapping were different with the change of months and were the lowest in April, and that positive ecological benefits of yellow sticky board trapping were recorded in May, June and July in the sod culture pear orchard, and in May and June in the clear tillage pear orchard, while negative ecological benefits were shown in the other months of the year. In conclusion, it is recommended to hang or remove the yellow sticky boards according to the specific habitat condition of the pear orchard and the dynamics of the pests.
