CATDOLL : CATDOLL: Why wasps are natural enemies of caterpillars

1. Why are wasps the natural enemies of caterpillars?

Wasps lay their eggs inside caterpillars (in the pupa state). After hatching, the wasp larvae will parasitize the caterpillars until they eat the caterpillars and break out of the body. In this way, they can kill the caterpillars, so they are called natural enemies.

2. What is the nemesis of flies?

The natural enemies of flies can be divided into predatory natural enemies, parasitic natural enemies, and microbial natural enemies.

Predatory natural enemies: including frogs, dragonflies, spiders, mantises, ants, lizards, geckos, robber flies and birds.

Chicken manure is a breeding ground for house flies and stable flies, but there are often ferocious giant chelicerae and earwigs in it, which will prey on small fly eggs and maggots in the manure. Parasitic natural enemies: such as parasitic wasps such as ichneumon wasps and small wasps, which often lay their eggs in maggots or pupae, and then eat maggots and pupae after hatching.

It was found that 60.4% of the flesh fly pupae dug out in spring were killed by parasitic wasps.

Microbial natural enemies: Japanese scholars have discovered that Bacillus Morita can inhibit the breeding of flies, and Chinese scholars have also found that if the spores of "Fly Monochamus fungus" fall on flies, the flies will be infected with the monochamus fungus.

There are three types of enemies of flies: the first is predatory organisms, including frogs, dragonflies, spiders, mantises, ants, lizards, geckos, beetles, wasps, robber flies and birds. Chicken manure is the breeding ground of houseflies and stable flies, but there are often ferocious giant chelicerae and earwigs in it, which will prey on fly eggs and maggots in the manure. The second is parasitic organisms, such as parasitic wasps such as ichneumon wasps and small wasps. The third is microorganisms, such as Bacillus Morita and spores of "Fly Monoclad Fungus".

1. Predatory organisms

1. Frog

Frogs are beneficial insects and omnivores. They are good at finding small moving insects such as mosquitoes, flies, moths, rice leafhoppers, locusts, etc. Once found, they will use their tongue to catch them. Usually, frogs eat 7% of plant food and 93% of animal food. Usually, they like mosquitoes and flies the most.

2. Spider

Spiders are beneficial insects. They usually fly into the house in summer to eat mosquitoes, flies, locusts, etc. When there is no food to eat, they will leave on their own. Usually, where there are spiders, there are few mosquitoes, flies, etc.

3. Dragonfly

Dragonflies are beneficial insects and also carnivorous insects. They usually like to eat mosquitoes, moths, flies and other small flying insects, and their appetite is relatively large. They can eat about 2,000 small flying insects every day, so dragonflies are also important natural enemy insects that are beneficial to humans.

4. Praying Mantis

Insects of the order Mantodea are collectively called mantises. Mantises are carnivorous insects. Both adults and larvae are predatory, feeding on other insects and small animals. They are well-known beneficial insects in agriculture and forestry.

5. Ants

The proportion of purely carnivorous ants, which mainly feed on insects, is relatively small, but each type of carnivorous ant has different food preferences, so not all insects can be used as food for all carnivorous ants.

6. Lizard

Most species are carnivorous, feeding on insects, earthworms, flies, snails, and even mice, but some feed mainly on cacti or seaweed, or are omnivorous.

7. Gecko

Geckos often appear on walls, under eaves or on electric poles where lights are shining. They prey on mosquitoes, flies, moths and spiders. They are beneficial and harmless animals.

2. Parasitic Organisms

They often lay their eggs in maggots or pupae, and the larvae eat maggots and pupae after hatching. It has been found that 60.4% of the flesh fly pupae dug up in spring were killed by parasitic wasps.

3. Microorganisms

Japanese scholars have discovered that Bacillus Morita can inhibit the breeding of flies, and Chinese scholars have also found that if the spores of "Fungi fungus" fall on flies, they will be infected with Fungi fungus.

Biological characteristics of flies:

The genus Fly is small to medium-sized, with short antennae and only three segments. The last segment has a whip at the end or a feather-like bristle on the back of the last segment, called an antennal awn (arista). There are two compound eyes and three simple eyes. The mouthparts are of the licking and sucking type. The forewings are membranous and used for flying. The hind wings are degenerated into a balance bar (halter), which is hidden under the wing petals at the base of the forewings. The mouthparts are of the licking and sucking type, and the upper and lower jaws are degenerated, leaving only a pair of rod-shaped mandibular palps; the lower lip is degenerated into a long beak, and the end of the beak is enlarged into a pair of lip petals with annular grooves. A sword-shaped upper lip is attached to the base of the back of the beak, and a flat and long tongue is attached to it, and the two are closed to form a food canal.

Fly damage:

1. Flies are harmful to humans because they carry a variety of pathogenic microorganisms. Flies have hairy bodies and their foot pads can secrete mucus. They like to crawl and feed on human or animal feces, urine, sputum, vomit, and corpses. They are very likely to be attached to a large number of pathogens, such as Vibrio cholerae, Salmonella typhi, Shigella dysenteriae, and Ascaris lumbricoides.

2. Flies often stay on human bodies, food, and tableware. When they land, they have the habit of rubbing their feet and brushing their bodies. The pathogens attached to their bodies will quickly contaminate food and tableware.

3. Flies have the habit of eating, vomiting and defecating at the same time. When flies eat, they first vomit out the crop fluid to dissolve the food before inhaling it. Moreover, they eat, vomit and defecate at the same time, thus vomiting out the pathogens that were originally eaten into the digestive fluid.

3. Are the Hornets the Rockets’ nemesis?

It should be the Warriors and the Suns! The Rockets lost to the Hornets just because they didn't adjust well!

4. Are the Hornets the Rockets’ nemesis?

It used to be that the Rockets were about to turn things around.
