L. lucidum is an important pest in apple orchards. In order to explore the ecological control of L. lucidum, in recent years, we have carried out trials to control the green-litter carp in orchards for the cultivation of rats and thatch in Jielu Village and Majingpo Village, Qiaotou Town, Huancui District, Weihai City. . The results showed that there was a significant reduction in the number of green grasshoppers in the turfgrass garden, and the annual planting effect was more pronounced.
These two orchards were originally cultivated in the Qingcang Park. From the autumn of 2010, the introduction of rat grass, one planting, successive year of grass, and 750 kilograms of hay per mu were produced on the ground.
Analyze the reasons for the reduction of the population of green-lipped enemies. The green-lipped carp is extremely miscellaneous. It breeds eggs inside the fruit tree bud scales. It damages the young shoots of fruit trees after hatching in spring. Its liveliness is lively. Once it falls on the ground, there are plenty of food sources underneath the grass garden. , stay in the ground to continue feeding. There are fewer weeds in the ploughing garden, and if there is no food source, it will return to the trees and the second and third generations may continue to harm the young shoots of apple trees.
