Science explains why grape skins are insected

It's fruit flies. It's too small to go through a screen window. Even if there are fruit fly eggs on the grapes, one night is not enough time to hatch into adults. So the flies the next day are all foreign.

The natural pigment in the grape skin has a good effect on lowering blood sugar and anti-cancer, while the natural pigment content of the dark grape skin is higher, and eating grapes helps sleep. Researchers tested a total of eight varieties of grape juice and found that it may contain melatonin, a sleep-aiding hormone. Melatonin is a substance secreted by the pineal gland in the brain that can help regulate sleep cycles and cause insomnia.

In addition to helping you sleep, grapes have many other benefits. Grapes are rich in nutrients, and it has been determined that eating 100 grams of grapes fresh every day can meet the human body's needs for 4% of calcium, magnesium, phosphorus, iron, copper and manganese for a day and night.

Grapes can nourish qi and blood, strengthen muscles and bones, pass through the meridians, reduce swelling, facilitate urination, and can play a role in tonifying the kidneys, strengthening the waist, nourishing the nerves and blood, lowering blood pressure, and appetizing, especially in the prevention and neurasthenia, stomach pain, bloating, cardiovascular diseases, etc.

Fresh grapes and grape juice are more resistant to viruses than wine, and red wine is stronger in wine. Red wine contains flavonoid compounds, especially querceone, which can reduce the viscosity of platelets, while spirits and beer do not have such benefits, so moderate consumption of red wine can play a role in protecting the heart and reducing the harm of cardiovascular disease.

Because the grape skins will smell after a long time, they will attract mosquitoes.

How to deal with mosquitoes:

1. Throw away any garbage indoors as soon as possible.

2. Don't leave food open in the house, and if you want to put it, cover it too.

3. Use a fly swatter, shoot when you see it, although it is not a long-term plan, but it is still very good in terms of relieving hatred and urgency.

4. Hang a few transparent plastic bags with half of the water at the doors and windows. The water in the bag reflects some light from the sunlight that can disturb the mosquito's sense of direction.

Because it has been in ** for a long time, it has caused mosquitoes, so there will be more and more! The same goes for watermelon skin, the grape will vomit crickets and then become the kind of insect that flies, so it can't be said to be a parasite, just like a melon and fruit are rotten, and there will be crickets after a long time, and then more and more, not to mention more, it's disgusting.

Suspected coal stain disease, is a fungal disease, spread by the aphid whitefly, it is recommended to fight whitefly aphid insecticide iprodione or pythium for control.

Aphids whiteflies have different pesticide resistances in different places. Generally, dinotefuran or thiamethoxam or dinotefuran or pymetrozine or thiamethroprid, etc., mixed bifenthrin is also OK.

Thiazinone kills eggs, does not kill adults, it must be mixed with other pesticides, thiazinone can not be used for radish, leafy vegetables, and is harmful. The egg-killing effect of pyridyl ether is also good, and it is ineffective for adult worms, so it is better to use it with the above products.

It is recommended to spray silicone spray, spray in the morning and evening, and apply thoroughly. Alternate pesticide ingredients. Protected areas can be combined with insecticidal aerosols.

Use pesticide ingredients alternately, and do not use the same pesticide ingredients consecutively. This is the principle of crop protection.
