There are a lot of fireflies in pumpkin seedlings, how to prevent them?

Fireflies are a kind of beneficial insects, we know from childhood that in the summer night sky, fireflies are like green lanterns in the sky, giving children unlimited imagination. And, it's safe to say that fireflies don't eat vegetable leaves. The larvae of the firefly night prey on snails and small insects, this kind of insect is the most common insect on our side, it is called yellow gourd, and the people on our side call it yellow flying worm; The size and shape of the yellow gourd is similar to that of a firefly, and many people think that it is a firefly that emits bright light at night, but in fact, it is called a pest of yellow gourd, and it does not emit bright light at night.

Many people think that pumpkin seedlings are infested by fireflies, but in fact, it is not fireflies that trample on pumpkin seedlings, but a pest that is very similar to the shaving signs of fireflies, called yellow gourds. Because it looks too similar to a firefly, it is often mistaken for a firefly.

<> pumpkin seedlings have fireflies can be sprinkled with grass and wood mud, and when there is dew on the seedlings in the early morning, they will sprinkle the grass and wood ash, because with a layer of ash, the fireflies will not climb on the pumpkin seedlings, and the fireflies belong to the beneficial insects, and he mainly eats snails. This kind of pumpkin pest, at that time there was fresh plant ash at home, I sprinkled a lot of pumpkin vine leaves, but it can make them temporarily reduced, but later I saw this pest to bite, a lot of it; I picked the more tattered leaves that had been bitten.

If it is not medicated for prophylaxis, it can be prophylactized with lime powder. Use hydrated lime powder and sprinkle evenly on the leaves, so that fireflies can't eat the seedlings. It should be noted that quicklime powder cannot be used, otherwise, the heat after wetting may burn the seedlings.

The seedlings can be protected with a protective cover to avoid being eaten by fireflies. You can use a plastic bag to cover the seedlings, and be careful not to use a light-tight plastic bag, otherwise, the seedlings will die. In addition, a certain amount of ventilation holes should be left to avoid poor breathing of seedlings.

Spraying melon leaves with a bit of mist and then sprinkling a little ash (the ash inside the wood stove) can prevent it.

Put some plant ash on top of the pumpkin, and the fireflies will stay away from the pumpkin after encountering the plant ash, and will not come to the pumpkin's side to harass them.

The method of control is to spray water containing salt on the surface of the pumpkin seedlings, which can prevent it, because this insect is very annoying.

You can spray pumpkin seedlings with some insect-repellent pesticides so that the fireflies will disappear.

We should spray some pesticides to prevent pests and diseases, and we should also spray some vinegar, so that's it.

Biological control methods can be developed, using the natural enemies of fireflies to catch fireflies, and some of the damage is also reduced.

It is likely that the local environment is particularly suitable for the growth of fireflies, so it is necessary to introduce its natural enemies so that control can be carried out.

I think it's time to put some insecticide on the pumpkin seedlings. This makes it not only fireflies, but also other insects afraid to come forward.

Fireflies are beneficial insects that do not harm pumpkins, but rather protect them. Fireflies are beneficial insects. We know from a young age that in the summer night sky, fireflies are like green lanterns in the sky, giving children unlimited imagination.

And, to be sure, fireflies don't eat leaves. The nocturnal larvae of fireflies eat snails and small insects, and the adults eat only dew, pollen, and snails. Fireflies are placed on snail shells during production and feed on snails.

Snails are pests and prefer the leaves of vegetables, fireflies like to eat snails, they are the natural enemies of snails, 100% beneficial insects, why prevent it?

In the biological world, fireflies are very sensitive to environmental changes, and the number of fireflies can reflect the state of environmental quality to a certain extent, so they are an ecological indicator insects. When we were children, we could always see sparkling fireflies in the evenings of summer and autumn, and sometimes we would catch them to play. Now there are very few fireflies.

This shows that the ecological environment has been seriously damaged. First, human beings have developed a large amount of land to change or destroy the environment where fireflies live, and second, the extensive use of pesticides and a large amount of sewage discharge have had a great impact on the survival of fireflies. In this regard, we should do our best to improve the environment and protect fireflies.

A bug that is very similar to the fireflies that harm amber species is the yellow water melon.

Fireflies are beneficial insects, why does the subject still have fireflies that eat his pumpkin saplings? In fact, this is the subject's admission of error. The bugs in the subject's pumpkin seedlings look like fireflies, but not fireflies.

This insect is called yellow fruit because it has a yellow habit and looks like a firefly, so it is called a yellow firefly. In fact, a closer look reveals the difference with fireflies. First of all, its body does not have the body of a firefly, and more importantly, its yellow water and abdomen do not have a luminous body like a firefly, and it does not glow at night with the main disease.

Bacterial wilt pathogen: Pseudomonas marginalisa dentosis. Fusarium wilt, also known as blight, is a fungal disease.

After the onset of the disease, when the disease of the whole plant wilts is high, the whole field of plants will wilt, resulting in yield saving. Pathogenesis rules and conditions. The pathogen overwinters in seeds, soil, diseased residues, immature or immature fertilizers, and begins to actively infect the following year when conditions are right.

Pathogens can invade through stomata in plant roots, wounds, or spread through underground pests, which have a high incidence when they are reported, and pathogens can survive in the soil for 5 to 6 years. Blighted diseases, low terrain, poor drainage, acidic soil, thick soil, excessive watering every year, heavy rain or untimely drainage when it rains, insufficient sunshine, too much nitrogen fertilizer or unripe fertilizer, and many underground pests may cause disease reports.

In the morning or evening when there is dew, sprinkle some plant ash directly on the leaves of the pumpkin, because in this way the plant ash is easy to stick to the leaves and not fall off, it is best once a day, about 2 4 days or so, the fireflies will fly to other places to find food, so that the planted pumpkin will not be harmed.

Melon seedlings have fireflies can be sprinkled with grass and wood mud, early in the morning when there is dew on the seedlings, go to sprinkle the plant ash, because with a layer of ash, fireflies will not climb on the pumpkin seedlings, fireflies belong to beneficial insects, he eats snails.

What we commonly use here is to sprinkle plant ash on the leaves and roots when the dew on the pumpkin leaves has not dried in the morning, which can generally reduce the spawning and gnawing of the leaves of the yellow gourd, and reduce the harm of the yellow gourd, or when the pumpkin seedlings are transplanted, they can also be sprayed with pesticides for control, which will generally reduce the harm of the yellow gourd.

Diseased plants can be wiped gently and repeatedly with alcohol, and the shellworms can be removed, and they can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the shellworms, but also completely kill the larvae that are not clear to the naked eye, and rarely find the damage of scale insects in the second year, this method is simple, safe and effective.

It is best to capture by humans or creatures, but chemical capture is also possible, and you must pay attention to the amount of capture.

It is more commonly used to sprinkle plant ash on the leaves and roots when the dew on the pumpkin leaves has not dried up in the morning, which can generally reduce the spawning and gnawing of the leaves of the yellow gourd, and reduce the harm of the yellow gourd, or when the pumpkin seedlings are transplanted, you can also choose 90% trichlorfon 1000 times liquid for spraying control, which will generally reduce the harm of the yellow gourd.

This is not a firefly but a melon insect, and the insect pest can be controlled by catching adult insects, and it can also be controlled by pesticides.

Spray some medicine because medicine can control pests, so you can avoid pumpkin infestation.

Summary. Firefly control: In the morning, preferably when the dew has not dried, sprinkle some plant ash on the cucumber seedlings.

Cucumber seedlings are eaten up by fireflies, how to prevent and control.

Firefly control: In the morning, preferably when the dew has not dried, sprinkle some plant ash on the cucumber seedlings.

Or use drugs for prevention and control: the bank can use 20% fenvalerate 30 times the preparation liquid, dip it in a cotton ball tied to the end, and finally insert the wooden stick directly next to the cucumber seedlings, which can effectively control firefly roller sensitizers.

The phenomenon of dead seedlings of cucumbers is a disease in addition to pesticide damage and fertilizer damage. Cucumber anthracnose, downy mildew, bacterial horn spot, and wilt will all cause dead seedlings.

Cucumbers are damaged by pesticides and fertilizers, resulting in dead seedlings. When giving cucumber insecticide and disease control, due to the high concentration, the seedlings can not withstand the high concentration of insecticides or sterilizers, and the pesticide damage is caused. Sometimes, in order to control weeds, when spraying herbicides that are very sensitive to cucumbers, the liquid will drift and the seedlings will die.

High concentration of chemical fertilizer liquid or solid fertilizer, due to improper use, resulting in root burning and dead seedlings. However, there will be no adverse effects within 5 times higher concentration of fertile leaves.

Cucumbers are affected by a variety of diseases that can cause seedlings to die. Anthracnose of cucumbers is easy to occur in fields with a lot of rain, low terrain and poor drainage, causing the whole seedling to dry up and die. Downy mildew of cucumbers occurs at the seedling stage, and the leaves gradually turn yellow and eventually die.

Bacterial horn spot occurs at the cucumber seedling stage, and round or oval water-soaked depression lesions will be produced on the cotyledons, which are yellow-brown and then brown and dry. If the seedlings are infected with wilt early, they can cause rot before they emerge, or the cotyledons will lose water, wilt and droop, and finally wilt and die.

In short, there are many reasons for the phenomenon of dead seedlings in cucumbers, which should be analyzed on a case-by-case basis and appropriate treatment methods should be taken to prevent and treat diseases.

There are a lot of fireflies in pumpkin seedlings, how to prevent them?

Hello, happy to answer your <>

Pumpkin seedlings have fireflies can be sprinkled with grass and wood mud, early in the morning when there is dew on the seedlings, go to sprinkle the grass ash, because with a layer of ash, fireflies will not climb on the pumpkin seedlings, fireflies belong to beneficial insects, he eats snails. Because the snail it is specialized in eating tender leaves. Generally, the lifespan of fireflies is about 5 to 14 days.

The time of bright light at night is a maximum of 2 to 3 hours. Therefore, it is good not to kill the fireflies and drive them away, it generally does not harm the crops of the Void Stool.
