What are predator insects?
Predator insects are insects that have long controlled the development and spread of pests in farmland, forest areas and pastures. It is divided into predatory natural enemy insects and parasitic natural enemy insects.

The praying mantis is a fierce insect, and its sharp "mantis knife" is enough to make people daunted.
Praying mantises can prey on a variety of pests, such as mosquitoes, flies, lepidoptera larvae and other small insects, cicadas, locusts, mantises and other large insects.
Common examples are the beautiful thin-winged mantis Mantis religiosa, which is known to prey on cotton bollworms, ground tigers, smoke green insects, armyworms, blind bugs, cotton aphids, leafhoppers, caddisflies, and small cotton bridgeworms in cotton fields.
In addition, the Chinese large knife mantis Tenodera sinensis named after "Zhonghua", as well as the widely captured broad axe mantis (broad-bellied mantis) Hierodula patellifera, and the dead-leaved large knife mantis Tenodera aridifolia are all well-known farmland beneficial insects.

There are many types of ladybirds, there are about 6,000 kinds in the world, and more than 700 species are recorded in China, of which more than 80% are predatory, 15% are plant-based, and the other 5% are bacterial.
The ladybug we are most familiar with is undoubtedly our childhood companion, the Seven-Star Ladybird, with its red shell and black and bright spots, which is very charming. What is rare is that the seven-star ladybug is not only cute, but also an authentic insect catcher: according to statistics, a seven-star ladybird can eat more than 100 aphids a day, and some places call it "Dr. Mai".
Although ladybugs are ugly when they were young, they are also experts at catching insects.
In addition to the familiar seven-star ladybirds, there are many predatory ladybirds. They are widely distributed and can prey on aphids, leaf mites, whiteflies, mesozoans, etc., and are important natural enemies for controlling agricultural pests.
Famous among them are: predatory cotton aphids, bean aphids, sorghum aphids, rape tube aphids, and the kaleidoscopic heterochromatic ladybird Hamonia axyridis:

In addition, the black-edged red ladybird, the Australian ladybird, the red-necked ladybird, the Chinese shield ladybird, the spotted small hairy ladybird, etc. are all extremely important natural enemies of farmland.

I knew that one day it would be dressed in gold armor,
Go on a highly anticipated occasion... Eat aphids!

Rifle beetles, commonly known as walking insects, are mostly predatory and play a role in the eradication of pests in nature. China's Venusian beetle preys on lepidoptera larvae in large numbers, and is an important natural enemy of pests such as armyworms, while also hunting harmful mollusks such as snails.

Nebria livida can prey on armyworms, ground tigers, green worms, locusts and harmful bugs.
Double-spotted green step nails
Double-spotted blue-footed Chlaenius bioculatus, also known as yellow star walker, its hatching larvae can prey after 1 hour of crawling, can prey on lepidopteran larvae that are several times larger than its body, and has the characteristic of preying on large larvae in clusters.
+ Cryptopteryx +
Insects of the cryptoptera family have short elytras and the hindwings are hidden under the forewings.
Some of the cryptopteracea are carriivistic and fecal insects, which can promote the circulation of natural substances; others feed on mushrooms, plant fruits and pollen; and most of them are mainly meat-eating, relying on preying on agricultural and forestry pests for a living.
For example, the black-tipped tiger Cryptoptera Stenus cicindeloides prey on aphids, leafhoppers, thrips, and lepidoptera. Green-winged cryptoptera Paederus fuscipes prey on corn borers, cotton leafhoppers, cotton blind bugs, cotton bridgeworms, cotton bollworms, cotton aphids, thrips and so on.
+ Salamander +
The fly [qú sōu] is an omnivorous insect of the order Leatherwings, also known as splints, nail clippers, and splints, which often live in bark crevices, dead sapwood or under leaf litters, preferring damp and dark environments. In fact, many salamanders are common predators in farmland.
For example, the green-footed small fat aphid Euborellia pallipes and the Japanese bulbophyllum Labidura japonica, which are widely predatory insects, can prey on many types of pests such as small tigers, cotton bollworms, cotton bridge worms, diamond diamonds, twill moths, red bollworms, short-fronted negative locusts, and cotton aphids.
+ Wasp +
Wasps, but the insect world's famous "violent temper" plus not good, did not think that they are also our farmland friendly army.
Northern wasp Vespula rufa prefers to prey on armyworms and silver-striped nocturnal moths; common long-legged wasps prey on cotton bollworms, small cotton bridge worms, pod borers, millet ash borers, and green worms. In addition, striped wasps, yellow-spotted wasps, Japanese long wasps, etc. are also beneficial insects in farmland.

"The borer has a son, and the borer bears the burden", which tells the story of the guǒ luǒ] of the mantis, which refers to the larvae of the lepidoptera, which carries the moth back to the nest and feeds its children.
Grasshoppers and wasps are somewhat similar in appearance, usually free to move, only when laying eggs to build a nest (or look for bamboo tubes), and then catch lepidoptera larvae, use the poisonous needle on their tail to anesthetize the larvae, lay eggs on them, for the offspring to eat. It can be seen that the grasshopper is a natural enemy insect of lepidoptera.
Common in farmland, such as rhynchium bruneum of the brown-beaked cockroach (yellow-lipped grasshopper), lays an average of about 15 lepidoptera larvae such as cotton bollworms under each egg. The anterior beaked grasshopper preys on the silver-striped night moth larvae, while the four-banded hedgehog and the yellow-encrusted grasshopper prey on the green worm.
+ Earth Bee +
The larvae of the earth bee family are exoparamates of grubs. The female worm dug a hole in the soil to find a host, and found that the grub first injected venom with stings, anesthetized the grubs, and then laid eggs on it, sealing the soil chamber.

Japanese earth bees are parasitic to the oil-tung green golden turtle; golden hair long-bellied earth bees are parasitic to the square-headed green golden turtle, cherry golden turtle and copper-colored golden turtle; and the white-haired long-bellied earth bee hosts are the great black gill golden turtle and the exotic golden turtle.
+ Grasshopper +
Grasshoppers are insects of the order Bulbophyllaceae. The words I can think of when I say "flying" are dignified and elegant: slender body, slender antennae, transparent wings, and compound eyes with a metallic luster, like a delicate woman who shuttles between flowers.
However, the grasshopper's larvae, the aphid lion, does not resemble its biological parents in the slightest, and its appearance is very different. Since it is called an aphid lion, it means that it is also an aphid killer, according to statistics, an aphid lion can eat more than 700 aphids in the entire larval stage, which is really a good appetite to create good insects.
Grasshoppers are really good at catching pests, not only all kinds of aphids - cotton aphids, vegetable aphids, smoke aphids, wheat aphids, bean aphids, peach aphids, apple aphids, safflower aphids, but also whiteflies, red spiders and so on are their prey objects.
In addition, grasshoppers also like to eat eggs of many kinds of pests, such as cotton bollworms, ground tigers, silver-striped nocturnal moths, wheat moths and small bridge-building insects, all of which are within their food range.

Bugs, which are our familiar farting bugs or stinky big sisters, are ugly and ugly in our memory, and they also have stink glands, which are particularly unpopular.
However, in fact, the bug is also a big family, there are more than 40,000 kinds of known in the world, with a variety of shapes and strange shapes, not only vegetarian bugs, but also many predatory bugs.
Insects of the family Flower Bugs, The Blind Bug Family, the Cockroach Family, and the Bug-Hunting Family can prey on pests such as leafhoppers, planthoppers, aphids, thrips, cotton leaf mites and cotton worms.
The bugs of the genus Floral Bugs are a class of natural enemies with important use value. There are nearly 100 species known in the world, more than 10 species are known in China, and in most of the farmland in China, the common dominant species are mainly East Asian small flower bugs, tiny flower bugs and southern small flower bugs. The small flower bugs prey on aphids, thrips and red spiders, as well as the eggs and hatching larvae of pests such as red bollworms, bridgebugs and cotton bollworms.

The black-fed aphids and heterophyllae of the family Plyidae prey on cotton aphids.
Nabis sinoferus of the family Heliophoridae is an omnivorous predator insect that can prey on aphids, lepidoptera eggs and hatching larvae in the field, as well as eat a variety of pollen. Nabis stenoferus mainly preys on cotton aphids, thrips, blind bug nymphs and lepidoptera pest eggs in the cotton fields.

In addition, the sandy big-eyed long-eyed long-eyed long-oysters in the family Long bug family prey on cotton aphids in cotton fields, and the cicada-like big-eyed cicada long-flyer is the main natural enemy of the northern cotton pest. Ama chinensis of the family Almachinidae is fond of coleoptera and lepidoptera pests such as elm leaf beetles and pine caterpillars, and is also a well-known natural enemy insect.

+ Aphids Fly +
Aphid-eating flies, the cos little bee guys, visit the flowers to collect nectar, shuttle between the flowers, and also pollinate the flowers like small bees.
The larvae "eat aphids", although ugly to the point of exploding in situ: maggot-shaped, with some transparent texture, can see the internal organs, at first glance like a lump of bird droppings.
But they are ugly and good-natured, full of skills: generally a larva can eat more than a hundred aphids a day, which is a good helper for the control of aphids. Of course, not all aphid-eating fly larvae feed on aphids, and some are scavengers or plant-eaters.
Aphid-eating flies are known for preying on aphids, but they can also prey on mesozoites, whiteflies, leafhoppers, thrips and lepidoptera larvae.
Common and well-known natural enemies include: broad-tailed thin-bellied aphid fly, short-spined stinging leg-eating aphid fly, mensie aphid fly, short-winged thin-bellied aphid fly, narrow-banded aphid fly and so on.

In addition, insect catchers, spiders (neither of which are insects) are also extremely important natural enemies of pests.
