China's pear producing areas are widespread and seriously endangered. In addition to harming pears, it also harms fruit trees such as peaches, apples and apricots. Due to its hazardous nature, it was more serious in the pear orchard adjacent to Taoyuan. The larvae invade from the pods and stems of the fruit and reach the fruit. The victim's fruit often begins to darken and rot around the hole, commonly known as the "black plaster," which is also a typical hazard characteristic of the pear fruit borer. In North China, 3-4 generations a year, the mature larvae in the pear tree branch cracks, tree holes and the soil around the neck knot scars overwintering. In North China, phlegm began in mid-April and was affected by food and climate. The occurrence period was very irregular and overlapped from generation to generation. The first and second generation larvae mainly ate peach or apple shoots, beginning in late July. Pear fruit into the rapid expansion period, the fruit's sugar content increased rapidly, this time Pear borer has entered the third and fourth generation, that began to eat pear fruit until harvest.

Prevention methods: (1) Agricultural control: Avoid pears and peaches mixed planting, and in winter, combine other pests to prevent and eradicate the old cracked skin on the tree and eliminate the overwintering larvae; and prevent and control the pear borer borers on peach and apple in time before July. In combination with other operations in the field, cut off the new shoots that have been damaged and deal with them in time to reduce the number of insects on the pear trees in the later period. (2) Biological control: Take advantage of the trapping, killing and fascinating effects of L. edulis sex attractants. When the trap catches adults, the egg fruit rate of P. rapae begins to be investigated, with particular attention paid to the investigation of the rate of eggs on earlier varieties. General egg fruit rate up to 1% can be medication. (3) Chemical control: It is possible to use the agents such as monthricin, diflubenzuron 3, diflubenzuron, and aweixinqing.
