No bugs. Worm-eaten walnuts can be seen if they are not treated, and their characteristics are not whether there are insect-eaten holes in the walnuts (because there are no holes in the shell, and the insects enter through the walnut pedicles) but whether the walnuts are stained with insect feces or husk shavings.

Whether walnuts are insects can be judged from the following aspects:

1.External manifestations: When walnuts are invaded by larvae, small holes may form in the walnut shell, and the holes may be covered by insect droppings, forming a small black spot. In addition, walnut shells may crack, thin, or soften.

2.Internal manifestations: When the walnut is opened, insect passages and feces can be seen.

Insect passages are the cannibalization marks left by insects inside walnuts and usually appear irregular tunnel-like. The size and shape of the worm tract depends on the species and stage of the bug. Insect droppings are the residue excreted by insects, which is presented as small granular objects.

In addition, when walnuts are severely infested, adults or eggs may be seen.

In short, if the above situation occurs in walnuts, it is likely to be worms. If the condition is severe, it is not recommended to consume it.

There are solutions in the walnut worm house:

1. Spray the insecticide, then prevent it from entering the sealed glass bottle, and finally put it in the refrigerator to freeze, and after one or two hours, even the spores of the small insect eggs can be killed.

If it is an old walnut, first confirm the authenticity, some fake walnuts resin into the air during the production process, and bubbles will be produced on the surface after molding. When the bubble bursts, small eyes appear, which look like insect eyes.

2. Mothballs to remove insects: Put walnuts and mothballs together in a bag, seal them, and after a few days, the insects will crawl out on their own before they die.

3. Zanthoxylum pepper insect removal: Put the walnuts into the bag, add some peppercorns, and then seal the bag, and then the insects in the walnuts will die, because the taste of peppercorns is more special.

Ways to prevent it. Because walnut kernels have a relatively strong shell, they are actually not easy to grow insects.

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%.
