What to do if there are bugs in the beans and how to get rid of the photo

One of the most useful and easy-to-maintain garden crops is beans. But gardeners often notice that bugs gradually appear in the harvested crop. This happens not only due to improper storage of the crop; the appearance of bugs in beans may also be due to its irrational harvesting. The main pests of legumes include aphids, weevils, sprout flies, root nodule weevils, whiteflies, and codling moths. To eliminate the possibility of their occurrence, every summer resident needs to know the measures to prevent and combat them.

Where do insects come to us from?

Many housewives who carefully keep their house clean often wonder: why are there bugs in the beans? Most often, insects appear due to the fact that sanitary standards are poorly observed in factories. Such consequences can be caused by neglect of heat treatment and violation of storage rules. This is why beans sold in stores may initially contain pests.

Beetles can also appear in beans by moving into them from neighboring products. Most often, bugs move into beans made from flour and starch.

Where do bugs come from?

It is not difficult to recognize a bean infestation with bugs. Rarely do pests go undetected for long. Typically, parasites are introduced along with purchased cereals, pasta, and flour. Insects quickly spread through cabinets and settle in all corners.

Another way of entry is through attempts by insects to escape the cold and unfavorable conditions. As winter approaches, parasites move closer to human habitation and, at the first good opportunity, enter the house.

Insects usually appear in shops and enterprises when storage conditions are not met. Beetles reproduce quickly when conditions are favorable for development. Such beans will end up on the shelves already contaminated and unfit for consumption.

It is worth considering that even purchasing cereals in a completely closed bag does not guarantee the absence of parasites.

What harm do they cause?

The bugs that appeared in the beans begin to actively eat the beans, filling the vacated space with the products of their own vital activity. Due to damage to the bean structure, it becomes unsuitable for further sowing. Moreover, such beans lose their beneficial and nutritional properties, so they are strictly forbidden to be eaten.

Whitefly

A white, moth-like, almost microscopic (1 mm) insect. It is visible only because whiteflies are numerous.

The pest prefers greenhouses, but in warm weather it also goes into open ground.

It is classified into a separate family - whiteflies. Polyphage, polyphagous insect. The flat, pale green larva does not reach a millimeter even before pupation.

It only harms beans if they are grown in seedlings and the seedlings are grown in a greenhouse. There it attaches to the leaves from below and feeds, oppressing young plants.

The whitefly does not tolerate open ground well. If beans are sown in the ground, this is the most reliable protection against the pest.

If the seedling method is necessary, simply freeze the greenhouse in winter. The whitefly will not survive.

How to fight?

Methods of bean pest control include proper preparation of the harvested crop for storage and ensuring the correct conditions for the preservation of beans. To do this, you need to know the optimal temperature, humidity level, and method of calcining the beans.

What to do if bugs are already infested in the crop? Unfortunately, such a product becomes unsuitable for consumption and further planting, so it must be thrown away.

To prevent crop contamination, you need to know the rules for controlling major pests. You can cope with bean weevil by treating the plants with Metafox and Decis before flowering. Repeated treatment is done 10 days after the first.

What to do if beans have bugs

The problem of damage to legume crops by small insects is very common.
Pests can appear even when beans are stored in a clean room. Bugs enter the apartment with store-bought pasta, cereal or flour. They often enter a warm apartment from the street in the fall, escaping the cold. Some insects remain among the grains after harvest. Therefore, it is recommended to carefully sort through the beans before storing them. Some insect pests attack legume crops during the ripening process. They lay their eggs in grains and use them for nutrition and reproduction. Fruits infected with them are no longer suitable for consumption. Therefore, if the presence of insects is not detected in time, you can lose the crop completely.

Where and in what should beans be stored?

Due to the fact that beans need to be kept cold, the refrigerator is considered the only optimal place until such time. If the beans are dried, they can be poured into a bag made of natural linen, and then placed in the vegetable compartment or on the door.

To protect yourself as much as possible from the appearance of pests, you need to place unpeeled garlic cloves and dill seeds next to the beans. Such additions repel pests. In winter, the beans can be transferred to the balcony.

What other preventive measures are there?

Recommended:

throw away heavily affected products;
place garlic cloves, bay leaves, nutmeg, and cloves in containers with beans;
Store beans only in hermetically sealed containers;
do not purchase large quantities of cereals and beans with the expectation of a long shelf life;
keep kitchen cabinets clean.

If infection is suspected, containers should be placed in the cold.

Plants can be treated with special preparations even before flowering begins. This will reduce the likelihood of infection and parasites. The main thing is to follow the instructions.

How to prepare for storage?

Since the bean beetle penetrates the beans at the stage of their ripening, before storing the harvested crop, it must be prepared. Before laying, the beans should be sorted and dried. To do this, they need to be placed in an oven preheated to 80-90 degrees for 5 minutes. After such heat treatment, the grains lose their ability to germinate, so such beans must be eaten. Many gardeners claim that in order to ensure a longer shelf life of beans, they should be separated from the pods.

How to store beans for the winter?

Green beans are canned and frozen, but grain beans are stored differently, since special conditions must be created for them. The optimal environment for storing this product is a temperature of up to 10 ° C and a humidity of less than 50%. With such indicators, the bugs do not start.

Where and in what should beans be stored?

It is best to pour the peeled grains into fabric bags or glass jars with tight lids (metal or glass). Plastic lids will allow air to pass through. For prevention, the bags are soaked in a solution of table salt and completely dried.

Store only in a cool place (refrigerator, balcony or basement). Optimal air humidity is 50%.

In a warm room, bean grains germinate. It is not recommended to eat sprouts.

How to prepare for storage?

The collected pods are pre-dried. They are laid out on tables in the yard, collected in bunches and hung on the veranda. When the pods become completely dry and the flaps begin to open slightly, it’s time to start shelling.

Sometimes bean grains are heated before planting. The temperature in the oven is not lower than 90 degrees.

Pests

Most often, beans are affected by bean weevil, sprout fly, slugs, and aphids. Therefore, the summer resident needs to know the characteristics and reasons for the appearance of these pests in the crop.

Bean grain

This pest affects bean crops in all regions, but most often it appears in the southern territories, which have a warm climate. The pest is a small beetle whose size ranges from 2-5 millimeters. Their body is characterized by an oval shape and a black shell. There are gray-yellowish stripes on the back. The bean weevil can fly long distances and also survive without food for 3 months.

The bean weevil is a heat-loving insect that does not tolerate cold weather. If the ambient temperature drops below zero, the pest dies.

Sprout fly

This pest is distinguished by its gray color, with darkening stripes on its back. Its length can reach 5 millimeters.

The insect lays eggs in the soil in April or May. If the weather is humid, larvae hatch from the eggs after 9 days. If weather conditions are dry, the eggs die. The surviving larvae penetrate the grains through the thinnest membrane in the area of sprout formation.

Slugs

The appearance of these pests is detected when traces of mucus are detected. During the day, slugs hide in the shade, and at night they go in search of food. They die if the temperature drops below 7 degrees.

Aphid

This pest is small in size, not exceeding 5 millimeters. It settles on new shoots and lower leaf blades. Such insects feed on plant sap, so such exposure can not only lead to the death of the crop, but also the entire plant.

At home

In order to preserve and protect beans from bugs at home for as long as possible, you should follow some basic recommendations.

Collection

As soon as the pods in the bed have dried and the flaps have opened a little, they can be removed. It is better to do this in sunny weather. A dry, ventilated room is suitable for drying. Otherwise, the beans will wrinkle and have an unsightly appearance.

After 10-14 days, peel the pods, sort the grains, sort them and conduct a thorough inspection for holes and damage.

Pest prevention

Before storing grain for later use as food, it is necessary to carry out a number of measures that will help reduce the risk of bugs appearing in the future:

Warm up Spread the beans that are selected only for cooking on a baking sheet in a single layer. Heat in the oven at 60 degrees Celsius. As a result of such manipulation, the larvae inside will die.
Exposure to low temperatures. Place the beans in a plastic container and cover with a lid. Place in the freezer for a day at minus 12 degrees Celsius.
Carrying out regular cleaning and maintaining cleanliness in the kitchen and storage areas.
You should not buy cereals, cereals and bulk food products in reserve . Such stocks are most susceptible to attacks by pests and can become places where they accumulate and spread.

Tara

Various forms are used for storage, which can ensure tightness and prevent penetration inside:

jars with vacuum lids;
plastic trays and bottles;
fabric bags;
bags made of polyethylene, cellophane, paper;
other containers.

Many housewives note the convenience of using bags made of various fabrics with ties. Treating it with a saline solution significantly reduces the chances of bugs getting inside:

Prepare a solution of kitchen salt in high concentration water.
Place the bag in it and leave it for a while to saturate.
Squeeze and dry.
Pour in the beans, tie, store in the refrigerator, on the balcony.

If using glass jars, add a little clean wood ash to the bottom.

Before use, containers and containers must be thoroughly rinsed with vinegar or citric acid. Rinse with running water. Steam glass jars additionally.

Required Criteria

Optimal conditions for best preservation:

temperature range within + 5-10 degrees, place – balcony, refrigerator, any dry, unheated room;
humidity level – no more than 50%, it is important to prevent dampness and mold;
container tightness;
periodic inspection to determine the condition of inventories.

Spots on grapes - what to do and how to treat bushes

To repel insects, some gardeners recommend putting garlic cloves, rosemary, dill or bay leaves inside.

Advice from an experienced gardener: partially fill a 1.0-1.5 liter PET bottle with beans, add 2 cloves of garlic. Fill to the top, cover with 2 more slices, screw on the lid.

Planting material

For planting, select large beans with shells without breaking the integrity or defects. After drying, spread paper or a towel in a dry place and distribute evenly. After a week, collect it in a linen bag and put it in the freezer for a couple of hours to kill the weevil larvae. Then place it in the refrigerator on the bottom shelf.

It is worth remembering the need to regularly check the condition of the planting material!

The day before planting, add salt water. Grains that float to the surface are rejected. It is advisable to grow beans for seeds separately from those intended for food purposes.

Diseases

In addition to pests, beans can also be destroyed by diseases. There are several reasons why beans turn black. To understand this, you need to know the main features of the diseases of this culture.

Powdery mildew

This disease is characterized by the appearance of a whitish coating on the leaves and stems of the plant. Gradually, the affected areas turn yellow.

Anthracnose

This pathology is distinguished by the fact that brown spots form on leaves, fruits, and stems. The leaves dry out and burgundy sores form on the fruits.

White rot

Affects stems and fruits. The infected areas become soft and gradually turn white. Rotting leads to the death of the planting.

Root rot

A whitish-pinkish coating appears on the roots. The beans are stunted and gradually die.

Bacterial spot

Under the influence of this pathology, the plant turns black. First, spots appear on it, which merge together over time. Gradually the planting fades.

Bean mosaic

With this disease, the leaves become variegated in color. Gradually, the leaves wrinkle and the plant withers.

Bean diseases

In addition to pests, during cultivation, beans are subject to various bacterial and fungal diseases and root rot. Rusty spots appear on the leaves, pods and roots, which then turn black. To combat diseases, use a 1% solution with Bordeaux mixture. To reduce the incidence of legume diseases, the beans are treated before planting. It is soaked in:

1% solution of potassium permanganate;
a solution of baking soda, prepared and 1 tsp. soda and 1 liter of water;
3% hydrogen peroxide.

They dig up the soil in the fall, keep the garden bed clean, and pull out the weeds in a timely manner. One way to reduce the incidence rate is to adhere to crop rotation. You should not grow legumes in one place for several years in a row. If possible, beans are returned to their old place for planting after 5-6 years. In addition, earlier planting in cold soil (at a temperature less than +10 degrees) leads to the bean becoming moldy, and too much deepening leads to a siege by pathogenic bacteria.

Protection measures

To protect plants from these diseases, it is necessary to get rid of pests, which often become their carriers. You should also provide optimal growth conditions for plantings and maintain humidity at the required level.

Preventive

If a summer resident is afraid that the beans will be affected by pests, he should prevent their occurrence. Most often, it is enough to use folk remedies that recommend covering the soil around the plants with dried nettles. You can also water the plantings with garlic broth, which will also repel pests.

Active

During the growth of the crop, the gardener is obliged to monitor the timeliness of development and the condition of the legume plant . This is necessary to identify the presence of a pest or disease at an early stage. Timely treatment will save not only the plant, but also the harvest.

Bean grain

“Name” bean pest. The small, harmful beetle is capable of destroying a crop completely.

Moreover, it works more – during storage. People will collect the harvest, dry it as it should be, package it in jars and on tables, where it is dark, for storage.

They take it out in the winter, deciding to try borscht with beans or some other dish. And in the jar there is no longer whole grain, each seed is a through sieve.

It was she who worked - the bean weevil. Although the beetle of the caryopsis family is polyphagous (it can also feed on other crops), it will definitely not pass by beans.

The black, small (up to half a centimeter) bug is close to beans in its demands on conditions.

It can develop at 13°, or better yet, higher. Therefore, he is active when his favorite crop begins to grow.

Even the egg-laying of the grain is extended for a long time: beans ripen unevenly. And the female is looking for beans and lays eggs on them.

The weevil needs beans - ripening so that the larvae can feed on ripe grain.

The bean weevil tries to lay eggs in the cracks of cracking beans. If he doesn’t find any, he gnaws out a hole in the back seam connecting the flaps.

One miniature female will leave fifty eggs there. Record-breakers have been spotted saving four times as much.

It is not difficult to imagine the degree of harmfulness of the beetle. More than fifty larvae sometimes feed on one grain at once.

In three weeks they eat up the entire seed. They pupate there, and a week later the beetles emerge, leaving a holey shell of the seed.

The insect is nimble: it runs and flies quickly. It also spreads quickly.

In the southern regions, the pest manages to produce brood four times in field conditions. It parasitizes in storage all year round.

If it is warmer than 10°C, then it breeds – constantly, as long as there is food. Can destroy all bean supplies.

If it is colder, it does not develop. But it doesn’t always die.

The larvae in the seeds can withstand zero temperatures for a month. Even minus four can be tolerated for half a month.

To ensure the destruction of the parasite inside the seeds, you need to freeze the grain for a day at –12°.

At this, or slightly lower, temperature, the adult beetles that have already emerged from the grains will die in the same amount of time.

What does a bug bite look like?

If there are parasites in the house, bite marks cannot be ignored. Waking up in the morning, you can see red spots and numerous spots on the body, which over time become inflamed and begin to itch very much. Typically marks can be seen on the back, shoulders and neck. After some time, the redness goes away and the itching stops, but there are cases of individual intolerance and allergies.

There are a number of signs by which bedbug bites are identified:

The consequences of bites are accompanied by a slight swelling with redness of the skin around and a protruding central part.
If you carefully examine the center of the puncture, you can see a small hole that the bug made with its proboscis.
Bed bugs rarely bite once. After the attack, a trail remains in the form of tracks at intervals of two to four centimeters. Tracks can start with single points and end with dozens.
After the bug leaves the bite site, blood continues to seep from under the skin for some time, so small bloody spots remain on the bed linen.
While sucking blood, the insect injects a specific substance under the human skin, which muffles pain and only after a while the wounds swell and begin to itch.
Bedbugs come out to hunt only at night; during the daytime they scatter in different corners. Only irresistible hunger can force them to leave the shelter during the day.
There is a strong burning sensation and a feeling of mild pain at the bite sites. These areas of the body become very itchy and begin to peel off.

The body's reaction depends entirely on the puncture site and the thickness of the skin. The skin on the neck and face is delicate; in these places, bites manifest themselves as more severe redness and swelling and serious pain. An allergic reaction of the body is possible, in which case you need to take an antihistamine.

Differences between bedbug bites and bites of other parasites

Each blood-sucking species has its own specific “style” of bite, traces of which remain on human skin. The methods of sucking blood by bedbugs differ from the bites of other insects.

Mosquitoes

When a person wakes up in the morning and sees inflamed spots on the body, there are assumptions that these are mosquito marks. At first glance, the bite left by a bug resembles a mosquito bite. But subsequently, the number of lesions on the skin, the smooth inflamed path and the bitten places inaccessible to the mosquito, are puzzling, because they were covered with a blanket all night.

The mosquito is not able to get under the blanket and night clothes. In addition, during the cold season there are no mosquitoes.

Fleas

Skin lesions left by fleas can actually be mistaken for a bedbug attack. But there are certain places on the human body that fleas bite most often - armpits, popliteal cavities, waist. These preferences differ from bedbugs. Visually, the mark of a bug bite is difficult to distinguish from a flea bite.

Midges

Midges operate in the summer and bite mainly on the street. The midge attacks open areas of the body, flies into the hair and bites into the scalp. Unlike midges, bedbugs do not bite a person's face. And the moment of a midge bite itself is much more painful, since it does not contain an anesthetic secretion.

Methods of fighting in the fields

To successfully eliminate pests, a number of measures are taken to help preserve the crop during cultivation and further storage.

Getting rid of the Colorado potato beetle forever: 6 most effective ways

Modern insecticides are most often used to treat crops against insects, such as:

"Atrix";
"Dimephos";
"SuperBison".

It is also practiced to treat storage areas – warehouses, hangars – with special disinfectants.

In order to protect bushes from weevil bugs in garden plots, it is recommended to carry out timely treatment of crops with chemicals during the ripening period. After harvesting, it is necessary to plow or dig up the soil at the planting site.

Popular and effective insecticides that are used in the fight against weevil:

"Decis";
Metafox;
"Phosorgan".

Spraying beds from a spray bottle with infusions of wormwood or garlic are considered effective folk methods.
