Why are slugs afraid of salt, slugs or salt oil bugs

Slug. I believe that people living in rural areas should be familiar with this small animal, but this small animal looks particularly sticky and dirty, so many people don't like to touch it. In addition, people who are familiar with this small animal should know that it is more afraid of salt, so why are slugs afraid of salt?

1. The reason why slugs are afraid of salt.

The slug is afraid of salt mainly because its epidermis is different from that of other animals, because its epidermis is made up of cell membranes.

This membrane does not prevent the diffusion of water. To put it simply, when the concentration of salt in the environment is higher than the concentration of the body, then the water in the body will naturally diffuse outward. Slugs need a lot of water to grow, and if a lot of water spreads out due to the concentration of salt, it will eventually die without water.

Second, the characteristics of slugs.

Slug is a colloquial name, but it actually belongs to mollusks.

Many people may think that it looks like a snail after seeing it. It is true that it looks like a snail on the outside, but if you look closely at its appearance, you will see that its body surface is always so wet, and there will be a lot of mucus on the surface of its body. Adult slugs stretch out about 30 to 60 mm, and their bodies are relatively soft, with a dull gray or yellowish gray surface.

Therefore, slugs are indeed more afraid of salt, and the reasons for this have been explained above. There are also the characteristics of this small animal, everyone should have understood it more clearly.

Its soft body contains a lot of water, about 90% of the body, while its epidermis has only a thin layer and is very easy to penetrate.

If salt is sprinkled on it, there will be a huge difference in the concentration of salt inside and outside the epidermis, and the water in the body will seep out through **.

On the one hand, this causes the slugs to die due to dehydration, and on the other hand, it turns the slugs into a shriveled corpse and the pool of water underneath the corpse.

It's the same thing that when we sprinkle salt on top of the vegetables when we pickle them, the vegetables will seep water. Sluggs are afraid not only of salt, but also of sugar. Sprinkle white sugar on it and kill it as well.

Slug is a general term for gastropods, stalk-eyes, and slugs. In some parts of southern China, it is called the slug (not the slug), which is a mollusk that forms a pulp with some snails. Hermaphroditic, it looks like a shellless snail with a moist mucus on the surface.

Slug takes the leaves of grape grape into holes, or eats its fruits, which affects the value of commodities, and is a harmful animal with complex feeding habits and large food amounts. Salt or sugar can be sprinkled on the slug, and after a few minutes, the body will be dehydrated and cause death.

Habits: Slug overwinters in the wet soil of crop roots as adults or larvae. From May to July, a large number of activities in the fields are harmed, and in summer, the temperature rises, and the activities weaken, and in autumn, when the climate is cooler, the activities are harmful. Wild slugs are afraid of light, and die in 2-3 hours under strong light, so they are active at night, starting from the evening, reaching a peak at 10-11 o'clock in the evening, and diving into the soil or hiding places before the early morning.

Strong hunger tolerance, can not eat or move in the absence of food or poor conditions. The dark and humid environment is suitable for its life, when the temperature and soil moisture content are 20-30%, it is most conducive to its growth and development.

Slug feeds widely, mainly eating potato, bread tree, ficus, blood tung, chrysanthemum, double-flowered chrysanthemum, vegetables, mushroom bulbs, mushrooms and other plants, fungi and their fruits.

How to get rid of slugs???

Sluggs, I know, it's just a sprinkle of salt, and I was told this when I was in Lianyungang, because there were a lot of slugs when it rained, and I didn't know.

Why do slugs melt into water when they encounter salt, and what's going on here?

1. Slug is afraid of high temperature and strong light, so it can be covered with plastic film to make it die due to temperature stress and lack of food, or increase the heat source or light source to improve plant physiological activity and photosynthesis intensity to prevent and control.

2. Mixing medicine in seeds can reduce the harm of slugs; Spraying crops can prevent it; Poison fumigation in the greenhouse can kill slugs on the ground and underground at one time; In the period of high incidence of slug damage, use poisonous bait and poisonous powder for prevention and control.

3. Sprinkle ginger powder, lime, plant ash, and aluminum sulfate on the slug-infested place to kill it.

How to completely eradicate slugs, have you learned?

Well, to be able to sprinkle ginger, one must sprinkle a little salt every day from the end of life, spray a little salt water, you can increase the flowering season to protect the flowers, and it will not be later.

Go to the agricultural materials store to buy a medicine called tetrachloropolyacetaldehyde and sprinkle it.

How to repel slugs:

1.Sprinkle ginger powder on slug-infested areas, slugs are very sensitive to the smell of ginger and will walk away. When slugs harm beloved plants, wrapping a thin copper wire around the roots of the plant has the same effect (slugs don't like the weak electromagnetic fields emitted by copper wires).

2.There's a disgusting way to do it, and it works very well. Put the caught slugs in a blender and add water to make a liquid, add lime juice, or lemon juice is better Use a watering can to spray slug-infested places, and you won't see a single slug for a few months.

3.Put a basin full of beer in a slug-infested area at night, and the next day you will see a fat slug drinking one.

4.Salt the slug: If you put salt on the slug, it will "melt" something like water and a layer of skin.

The reason is that the water content in the body is very high, resulting in a very low salinity in the body, and the water is transferred from low concentration to high concentration. And so it's getting smaller and smaller, giving the illusion that it's turning into water.

5.Sprinkle aluminum sulphate on slug-infested areas. Aluminium sulfate is also effective against other mollusks.

6.There are two other ways to kill slugs (slugs), one is to spray the ground with concentrated salt water to get rid of the adults, and the other is to use rice bran or soybean cake to add calcium arsenate or aluminum arsenate to make poison bait. Disinfection of outdoor gutters, sewers and other places can be treated with 6 of the extinguished.
