In 2017, the peach tree planting disease was used to control the control method of the small Ginkgo worm in the flowering stage of the walnut tree. As the weather turned warmer, the small G. sylvestris began to be active. Xiaojiding insects damage the branches of the cortex with larvae and are important pests of walnuts. The newly hatched larvae plunged into the epidermis of the branches from the lower side of the egg. As the worms enlarged, they gradually penetrated into the spiral between the cortex and the xylem. They were covered with brown worms, and the surface of the damaged branches had inconspicuous pupil marks and many Crescent-shaped vents. The branches with severe damage, the leaves are yellow and early, and most of the branches of Hunchun are dead, causing a large number of dead branches. Control method: Strengthen the management of water and fertilizer by deep-turning the soil, adding organic fertilizer, timely topdressing, rational intercropping and plastic trimming, and enhancing the resistance of the walnut tree itself to disease. From April to May, after the germination of the walnuts until the adults are feathered, the seeds are burned and the larvae and mites are destroyed before the leaves are harvested. Strengthen integrated management 1. Biological control. There are two species of parasitic wasps in the small genus of the walnut, and the natural parasitism rate is 16% to 56%. The release of parasitic wasps can effectively reduce the number of wintering insects and reduce or reduce pests. 2. Chemical control. When the saplings are killed, they are often inspected during the larval hazard. It is found that there are holes in which the larvae break in, and the dichlorvos can be applied to the pests. In the adult stage, combined with the control of pests such as walnuts, the canopy spray is applied. The bait wood is trapped in the adult feathering spawning period, and some bait woods are set up in time to induce the integrated insects to lay eggs and burn them in time. Thoroughly cut off the insects and combine the harvested walnuts, and completely remove the yellow leaves of the damaged leaves or destroy them before the adults emerge.
