Can aphids be eaten, and what do aphids eat for a living?

I haven't seen anyone eat it, so I guess it's okay.

Most of the aphid species are oligophagous or monophagous, a few are polyphagous, and some species are important pests of economic plants such as grain, cotton, oil, hemp, tea, sugar, vegetables, tobacco, fruits, medicines and trees. Due to the repeated transfer of food during migratory dispersal in search of host plants, many plant virus diseases can be transmitted and cause greater harm. These include important pests such as Aphid long-piped, Aphid bifurcata, cotton aphid, peach aphid and radish aphid.

How aphids eat.

Aphids use stinging mouthparts to suck food into plants. Aphids have a pair of abdominal canals, which are used to drain the defense fluid that can harden rapidly, and the composition is triglycerides, the abdominal canals are usually tubular, often longer than wide, and the base is thick, sucking plant sap, and is a large pest of plants.

It not only hinders the growth of plants, forms worms, spreads viruses, but also causes deformities of flowers, leaves and buds. The life history is complex, wingless females camp parthenogenesis in summer camps, ovoviviparous, and give birth to young aphids. When the aphids on the plant are too dense, some grow two pairs of large membranous wings in search of a new host.

Female and male aphids appear in late summer, and after mating, the female aphids lay eggs, overwinter with their eggs, and eventually produce a dry mother. Egg-free period may occur in warm regions. Aphids have wax gland secretions, so many aphids look like white wool balls.

Aphid reproduction: Aphids reproduce in both hermaphroditic and parthenogenetic reproduction, oviparous or ovoviviparous.

Throughout the year, winged or wingless parthenogenetic viviparous aphids reproduce offspring, that is, they do not need to mate with male aphids to produce offspring, and the eggs stay in the mother's body until the embryo matures and is excreted from the body, and it is born as a small aphid. Aphids can also produce winged or wingless aphids with the rise and fall of host plants, and can migrate in search of suitable pests.

Aphids develop quickly, have a short life cycle, and can complete a generation in seven or eight days, so their reproductive ability is extremely strong, and an average tobacco aphid can produce more than 70 offspring; In addition, aphids have a wide range of food, and some aphids can parasitize on more than 100 kinds of plants, so they are widespread and serious, and have become important pests in the world.

Aphids eat leaves.

Aphids, also known as honey worms and greasy insects, are herbivorous insects and one of the most destructive pests. There are many species, many of which are more harmful to agriculture and horticulture. In particular, it harms crops such as wheat, oats, barley, etc.

After discovery, measures must be taken to treat it as soon as possible, otherwise the reproduction rate will be fast and the harm will be more serious. Prevention and control can be carried out with drugs, artificial and natural enemies.

Control of aphids

With the continuous development of agricultural planting technology, there are more and more pest control measures for rapeseed, and pesticides that are less harmful to rapeseed can be selected when carrying out aphid control of rapeseed. At present, there are many drugs with high efficiency and low toxicity, including cyfluthrin and pyrrole.

insecticides, etc.

Compared with chemical drug control measures, biological aphid control measures can better ensure the safety of rapeseed. Biological aphid control measures are mainly based on the use of beneficial insects.

The control of natural enemies of aphids is the most commonly used means in the control of biological aphids.

The insects that eat aphids include seven-star ladybugs and aphid cocoon wasps, as well as lacewings, ladybugs, aphid-eating flies, aphid cocoon wasps, aphid molds and other insects are the natural enemies of aphids.

Insect control is a more effective way for human beings to fight pests, aphid cocoon wasps are the natural enemies of aphids, in order to eliminate aphids can be said to have made a great contribution, and the insects that attack aphids have parasitic wasps, aphid-eating gall mosquitoes, aphid lions, crab spiders and lacewings are all insects that attack aphids.

The larvae of the lacewings are aphid lions, which are powerful predators of aphids, and they are constantly crawling on plants to find pests, whether they are larvae or when they are grown.

Seven-star ladybugs, heterochromatic ladybugs, etc., they feed on aphids all their lives, and the number of aphids they eat is relatively large. Aphid-eating flies catch aphids in greater numbers. Crab spiders refer to spiders of the order Crab Spider family, which also prey on aphids as food, crab spiders are not only shaped like crabs, but can also run rampant or backwards like crabs.

Pests are often caught in grass or wheat fields.

There are many ways to eliminate pests, chemical control is the use of pesticides to get rid of pests, this method is relatively effective, not limited by geography. A more long-term solution is to use insect control methods, which can not only reduce insect infestation, but also protect the ecological environment. It is also possible to breed varieties that are resistant to diseases and insects, and reasonably avoid the damage of pests to food.

Aphids are one of the most destructive pests on earth, including all members of the total family of aphids, ranging in size and length from one to ten millimeters, parasitic plants include almost all families of angiosperms and gymnosperms, and some species are hosted by bryophytes, ferns and equisetae.

Ladybug ladybug is the common name for the round protruding beetle of the Coleoptera ladybug family, often with red, black or yellow spots, and predatory ladybugs mostly feed on aphids. Many ladybugs live only in specific habitats, sometimes limited to a few plants in a particular habitat. On the contrary, many species such as heterochromic ladybugs and turtle ladybugs are widespread and can be found in many habitats, leaving them in search of food when there are fewer prey in their habitats.

Aphid-eating flies are effective natural enemies of aphids, scale insects, whiteflies, leafhoppers, thrips, small larvae of lepidoptera, etc., and are insects of the family Aphids of the order Diptera and are known for their larvae preying on aphids. Adults are small to large, wide or slender, with a single dark body color or often bright color markings such as yellow, orange, gray and white, and some species have metallic colors such as blue, green, copper, etc., and look like a bee.

Parasitic wasps parasitic bees refer to a variety of insects that live on parasitism, such as the family of golden bees, the family of the family and the family of small bees, and there are many kinds of insects that live on parasitism, which are parasitic in different stages of the development of the host, and the common ones are small wasps, jie bees, cocoon bees, red-eyed bees, rodent wasps, etc.

Aphid-eating gall mosquitoes. Aphid-eating gall mosquito is an insect of the gall mosquito family of the order Dipteridae, distributed in Hubei and other regions, and the host insect is cotton aphid, which overwinters under the topsoil around the host plant of the aphid with cocoon larvae, pupates in March and April of the following year, and lays eggs and reproduces on early spring hosts such as weeds and hibiscus with aphids after feathering and mating.

Crab spider crab spider refers to spiders of the order Crab Spider family, which not only resembles a crab, but can also run sideways or backwards like a crab. With the spirit of fighting big with a small one, it will prey on insects that are much larger than itself, such as butterflies, damselflies, mosquitoes, bees, etc. It often hunts pests in flowers and grass or bean fields, or in cotton fields and wheat fields close to bean fields.

Lacewings are a large family in the order Phylla Insects, with a wide variety of species, which are distributed in most areas of China, and are important natural enemies of various aphids such as pine aphid, willow aphid, peach aphid, pear aphid and pine scale, which play an effective role in inhibiting the growth and decline of the population of aphids and scale insects in forest nurseries and orchards.

What insects eat aphids? The natural predator of aphids is the aphid cocoon wasp. Humans have had countless battles with pests, and using the natural enemies of pests to control insects is one of the most effective methods.

As the natural enemy of aphids, the aphid cocoon peak has made great contributions to the eradication of the world's largest pests for human beings.

Ladybug. Ladybugs are the natural enemies of aphids. Both larvae and adults of ladybugs eat aphids.

The details are as follows.

There are many types of ladybugs, some feed on aphids, but some don't eat aphids. For example, most of the ladybug subfamily and the eye-catching ladybug subfamily mainly feed on trapped aphids, and the small hairy ladybug subfamily and the small ladybug subfamily also prey on aphids, and among the predatory ladybugs, the seven-star ladybug is the most common natural enemy of aphids. Ladybugs that feed on aphids are found in the wild

Seven-star ladybug, heterochromic ladybug, six-striped ladybug and tortoiseshell ladybug.
