The insects of walnut trees are usually yellow thorn moths, also known as hemp calls, foreign peppers, etc., in recent years, the development of secondary pests has become the main pests of walnut trees, from early July to late August is the peak period of yellow thorn moth larvae, the larvae of 3 instar are clustered together, feed on the lower epidermis and mesophyll of the leaves, do not eat the upper epidermis, form a round transparent small spot, the leaves are reticulated, the 4th instar eats the leaves into holes, and the larvae above the 5th instar can eat up the leaves, leaving only the leaf veins, and the leaves are mesh-like.

Biological control: There are many parasitic natural enemies of the stinging moth, for example, the parasitic natural enemies of the yellow thorn moth have been found to be the spiny moth purple wasp, the stinging moth broad-shouldered wasp, the Shanghai Qingfeng, the Javan spiny moth b. bee, the robust stinging moth parasitic fly and a kind of velvet bee. The natural enemies of the longitudinal ball-whiskered moth, the green thorn moth, and the yellow-edged stinging moth eggs are the red-eyed wasp; The natural enemies of stinging moth larvae include Beauveria bassiana, green worm fungus, and branchopolyhedrosis virus, all of which should be protected and utilized.

There are different kinds of bugs in walnuts. One common walnut insect is the peach borer, also known as the peach borer, which is an insect of the genus Wax Oak borer in the Lepidoptera family Grass Borer. The larvae of peach borer, commonly known as heartworm, are major fruit-eating pests, mainly harming walnuts, figs, chestnuts, corn, sunflowers, peaches, plums, hawthorns and other agricultural and forestry plants and fruit trees.

Another common walnut bug is the walnut lift-limb moth, also known as walnut black, which mainly harms walnut fruits. The larvae of the walnut limb moth eat many tunnels in the green skin, full of insect feces, and the green skin of the infested place turns black, which harms the early seed kernels to shrink and fall early, and the late ones turn black.

In addition to these two common bugs, there are walnut bugs such as wood inchworm, yellow thorn moth, paramecium scale insect, walnut small gidding worm, etc. These insects are more harmful to walnuts and need to be controlled in time. Among them, manual control methods include timely removal of diseased fruits, ploughing the soil to eliminate overwintering insect cocoons, using sexual attractants or agents to trap adult insects, etc., and pesticide control needs to be carried out under the guidance of professionals.

Peach borer. The small black worm in the walnut is the peach borer, which is a large fruit-eating pest, the first generation of larvae mainly harm the apricot and early ripening peach fruit, the second generation of larvae mainly harm corn, sunflower flower plate, etc., the third generation of orange larvae mainly harm walnut, chestnut, etc. Walnut kernels have a direct antibacterial and anti-inflammatory effect, according to clinical reports, walnut tar zinc oxide skin paste made by mashing walnut kernels, **dermatitis, eczema, effective rate up to 100%.
