Who eats insect aphids other than ladybugs?

Entomophages are insects that gobble up other insects “on both cheeks.” Recently, there has been a tendency to distribute the most useful of them around the world. Opponents of GMOs, pesticides and other chemicals in the fields actively advocate for this.

How to deal with aphids in June

Such insects “shoulder to shoulder” in a single cohesive formation, together with ordinary summer residents, stand to protect the garden from all kinds of pests. Today we will talk about using this approach in the fight against aphids.

In addition to ladybugs in the adult stage and their equally voracious larvae, aphids have many other natural enemies. Insects include: predatory bugs, Atheta coriaria beetles, Aphidius wasps and other ichneumon wasps, ground beetles, earwigs, lacewing larvae, hoverfly larvae, fire beetle larvae.

By the way, people can also be entomophages. In any case, in the countries of Southeast Asia, Central and South America, dishes with insect larvae and other beetles are not considered something out of the ordinary. It’s not worth mentioning that in France they serve dishes with grape snails for big money.

Considering the prices for beets, carrots and chicken this season, natural food rich in environmentally friendly proteins may well complement the usual diet of both a summer resident and an amateur gardener.

Wasp Aphidius Colemani

I don’t know how many summer residents have watched the film “Alien,” but in this situation the analogy would be quite appropriate.

Aphids, thrips, whiteflies - all of them are suitable to become living incubators for the larvae of the overly prolific and formidable entomophage - the wasp Aphidius Colemani.

Aphidius, by piercing the outer shell, lays a small egg into the body of the victim, from which an incredibly voracious carnivorous larva soon emerges. Without wasting a single free second, it begins to devour the body of its owner from the inside, and then uses the lifeless outer shell as a cocoon for pupation, from which an adult emerges after some time.

Signs of plant damage

Aphids on plants.

External signs of aphid infestation include:

the presence of larvae or adults on the leaves;
painful condition of the leaves. They turn yellow, elasticity is lost, and death occurs;
weak inflorescences with no ovaries;
viscous and sticky surface.

The underside of leaves and flowers are favorite habitats . The appearance of the larva occurs up to 14 days. The life cycle lasts up to 30 days. The larva actively feeds on sap, which contains a lot of nutrients.

You can get acquainted with aphids in the article at the link.

Earwigs

Many summer residents do not like and are even afraid of earwigs and try to drive them away from the site as quickly as possible. Meanwhile, these insects, armed with powerful mites, actively eat aphids, woodlice and other garden pests.

The larvae hatched from the clutch are so insatiable that they often devour their own mother, who carefully guarded them throughout the long winter.

If you are not afraid of accidental earwig bites, try to create favorable conditions for them in your dacha, in particular, by installing flower pots with wood shavings, laying out plywood and planks in damp nooks.

Insect predators

In nature, there are natural enemies of aphids, predatory insects and birds, for which they represent a diet. They can help a person fight such insects.

The main lover of tasty aphids is the ladybug and its larvae. Therefore, they are assistants in the garden to destroy pests. According to scientists, one beetle can eat 50 aphids or their eggs per day.

Predatory insects that eat aphids Especially quickly destroy small parasites of the larvae of ladybirds, which in appearance are not at all similar to adult individuals. They are gray-black in color and flatter in shape, have red-yellow spots on the sides, and are larger than their parents. Since they are still growing, they need to eat well. Each young individual that feeds on aphids is capable of absorbing 70-100 units per day, which brings great benefits to the garden.

Interesting!
Observations by biologists show that when ladybugs attack, the entire colony of pests panics, active movement begins, and many winged individuals appear, which in this way escape from the attack of a predator.

In addition to colorful beetles, aphids form the basis of the diet for lacewings and sand wasps, which can eat 100-150 individuals per day.

Among insects, aphids are also eaten by those species for which they are food only when encountered: earwigs, cicadas, crickets, hoverflies, ground beetles and several species of spiders.

Important!
These types of insects are of great benefit to the garden, so before using insecticides, gardeners should think about the fact that they will kill not only pests, but also those who benefit.

Birds that eat aphids

Ants are reliable bodyguards, but only in those cases when we are talking about opponents of comparable strength from the world of insects. If birds get involved, these well-coordinated workers, without saying a word, abandon their “pastures” and hurry to get away.

Among those who like to snack on aphids are sparrows, tits, linnets, wrens, warblers (willow warblers and chiffchaffs), kinglets and some others.

When robins hear a voice, the aphids should immediately begin to move their “rolls” more actively.

Prevention

In order to avoid having to frantically search for many methods to combat aphids in spring and summer, it is necessary to carry out health procedures in the fall. An initially well-kept garden will only work to your advantage.

In order to reduce the number of aphids settling on your site, you need to carefully monitor the condition of the trees. Seasonal whitewashing is also a must. Remove leaves and dead wood that has accumulated on the ground. Reduce the number of anthills. Plant care is the main method of pest control .

Practical significance of bloodworms

Another name for mosquito larvae is bloodworm. Since not only toads, but also fish actively feed on these small worms, they are often used by aquarists, as well as experienced fishermen. Bloodworms go on sale after careful packaging. This is because small larvae are suitable only for aquarium phenotypes, but large ones are suitable for catching river fish. How actively a barb or gudgeon will consume mosquito offspring depends on the degree of its freshness and proper preparation. Therefore, experienced fishermen purchase larvae for feeding only in specialized departments.

Nutrition of aquarium fish

Many aquarium phenotypes feed on mosquitoes and flies. The following varieties are preferred for bloodworms:

Trout.
The Golden Cockerel.
Whitefish.
Roach.
Cichlids.
Gury.

The amount consumed by a particular phenotype depends on its size as well as taste preferences. Some river fish feed only on mosquitoes and their larvae. Anglers take advantage of this by using fresh bloodworms for feeding. Some phenotypes catch those mosquitoes that move above the water surface. Other species use a stream of water to dislodge the insect and obtain the required amount of food. Most often, the pests are knocked down by splashers.

The use of larval-eating fish in the fight against malaria

Among those that feed on the larvae of malaria mosquitoes are the mosquito fish. These fish are found in America. They live and develop both in the central part and in the south. Although their diet may include zooplankton that is of suitable size, mosquito fish prefer bloodworms. Therefore, these phenotypes settle in water bodies that are filled with the offspring of malaria mosquitoes.

Since mosquitoes cause significant harm to people around the world, mosquito fish are artificially bred in many bodies of water. Today they are found not only in the USA, but also in Russia. Gambusia were actively bred on the Black Sea coast in the 50s. At that time, a huge number of soldiers and ordinary citizens died from malaria in the Caucasus. It took about 10 years to completely cope with the disease, as well as destroy the huge population of malaria mosquitoes.

Now scientists are actively reducing the populations of mosquito fish. This is because fish can eat not only bloodworms. If there is a lack of food familiar to them, then gambusia eat fry and young fish that are unable to defend themselves.

Ladybug feeding

When the temperature rises to 13 degrees Celsius, most of the ladybugs already cover shrubs, grass meadows, grain crops, forest plantations and other green spaces.

They are very fond of alfalfa and barley fields. The activity of beetles increases due to a favorable climate and the appearance of additional food, because their favorite delicacy, aphids, appears on shrubs and grasses.

Just for the development of one larva, 1000 aphid insects are needed. The daily diet of an adult beetle is up to 200 insects.

Thus, the beetles destroy a huge number of aphids, thereby saving farmers from the destruction of their crops.

Spreading

Today, about 4,000 species of aphids are known, of which about 250 are serious pests. Scientists believe that the number of species of these herbivorous creatures was much smaller before the appearance of angiosperms (flowering) plants in nature. The evolution of plants has allowed for the birth of many more species of aphids as the number of plants themselves has increased.

Twenty-five percent of all plant species can be affected by aphids.

This type of pest has a worldwide distribution, but most of them are found in temperate zones; for example, in central Russia there are approximately 500 species of pests. Most aphids are monophages, although some are able to feed on more than one type of plant, for example, the green peach aphid Myzus persicae, so widely known to us, can infect almost all cultivated plants in our garden. But it is worth noting that this is very rare in the nature of these insects.

How to destroy with drugs?

The modern market provides many chemical insect repellents:

Pesticides and insecticides are used to kill pests. The most popular are:

"Aktara".
"Tanrek."
"Admiral".

Also among summer residents, biological preparations are widely used to kill aphids.
The most commonly used are Akarin, Actofit and Fitoverm. The advantages are obvious - the main substance is isolated from natural raw materials and does not tend to accumulate in plants. But, unfortunately, not all such drugs are non-toxic; for example, Fitoverm is quite dangerous, especially for children.

Other methods

Despite new and proven methods for killing aphids, many people prefer traditional methods. Among the most effective are several methods:

Spraying with water .
A stream of liquid can knock insects to the ground, from where they can no longer return to the plant. This method is suitable exclusively for early spring, when aphids are just emerging and do not yet have wings for movement, and large concentrations of ants are undesirable on your site, since they are the ones who carry aphids (you can find out more about the symbiosis of ants and aphids here).
Soap solution . The sharp smells of soap will help repel pests; it is best to use household soap and tar soap. Preparation: 100 gr. dissolve soap in 10 liters.
Ash infusion. This method is effective in two directions at once: ash is an excellent fertilizer for the garden and at the same time fights pests.
Then boil and cool.
Afterwards you can spray the plants.

In order to no longer be bothered by the problem of aphids in the garden and you can regularly get a good harvest and moral satisfaction from work, pay great attention to caring for plants, follow the basic rules for their prevention, pay attention to high-quality soil fertilization and be sure to attract useful ones to the site. insects _

All of the above methods will help you effectively prevent or destroy the development of aphids.

Preventive protective measures

It is impossible to get rid of aphids by one-time treatment of already diseased plants. It is necessary to constantly inspect plants and take preventive measures to protect yourself from damage by pests, including aphids.

Prevention includes agrotechnical measures, such as choosing a site for a rose garden, lighting, adequate watering, and fertilizing. Particular attention is paid to caring for roses. They need:

systematic examination to identify parasites,
removal of dry leaves and faded stems of roses, painful pruning, weakened shoots, which are most often affected by pests and diseases,
periodically (once a month) washing the plants with clean water or soap solutions. Aphids are inactive, and when washed off with a stream of water, as a rule, they do not return, but die.

Consumption of cockroaches by humans

Humans are also on the list of animals that feed on cockroaches. In Asian and African countries, insect dishes are offered in expensive restaurants. They are specially bred in insectariums. These and similar creatures are considered healthy dietary foods. Small cockroaches are eaten at home, fried in a frying pan. In restaurants and cafes, cockroaches are served in various sauces, both raw and cooked.

The list of those who eat cockroaches is quite small. Prussians are not the main food for anyone. These insects are fed to the inhabitants of terrariums twice a week. Birds, monkeys and rodents eat far fewer pests.
