CATDOLL : CATDOLL: How maggots are produced

How do maggots come about?

Maggots are produced from eggs laid by flies.

Maggots are hatched from fly eggs. Because fly eggs are too small, people cannot easily see them, so they mistakenly believe that maggots grow on their own. Maggots are also called fly larvae, so maggots should not be produced without flies.

Flies like to lay eggs in a humid and protein-rich environment. The eggs can usually turn into maggots after 6 hours, the maggots can turn into pupae after about a week, and the pupae can turn into flies again after about a week.

Putting feces in a small environment with air will prevent maggots from being produced.

The growth process of maggots

The eggs of maggots hatch at 15 degrees Celsius and at 40 degrees Celsius. They are about two centimeters long and wriggle and wriggle. Modern science has discovered that maggots are rich in protein and can be used as medicine or food. Maggots are the larvae of maggots and flies. Also known as meat worms and meat buds. Everyone has seen flies, but not everyone knows.

Flies are insects that undergo complete metamorphosis. Their life cycle can be divided into eggs, larvae, pupae, and adults. Most female flies lay eggs, but they also produce larvae. The pupa turns into a chrysalis after 3-4 days of pupa, and the pupa is a winged fly.

Maggots, also called fly larvae, are the larvae of flies, so maggots will not be produced in the absence of flies.

Evolution: maggot - pupa - fly

Flies lay their eggs in places with suitable environments (usually toilets, sewers, decaying materials, garbage dumps and other places with high organic matter content). After natural hatching, the eggs become maggots, which then undergo metamorphosis and develop into adults.

There is a very famous experiment.

Italian biologist and doctor Redi once used experiments to verify whether rotten meat can produce maggots.

Reddy placed various meats, such as beef, mutton, venison, and snake meat, in open bottles and allowed them to rot. After a few days, maggots grew in the rotten meat. Reddy observed very carefully and saw that the maggots turned into pupae, and the pupae turned into flies. He also noticed that when flies hovered, they sometimes dropped small objects on the meat, and flies would also leave some small objects after crawling over the meat. He suggested that maggots were probably transformed from these small objects left by flies on the meat.

In order to verify this idea, he designed a very simple experiment in 1668. He put pieces of fresh meat in different containers, some of which were covered with gauze and some were not. In this way, flies could not lay eggs in the bottles covered with cloth. After a few days, maggots grew in the meat in the open bottles where flies could freely enter and exit, while in the bottles covered with gauze, although the meat also rotted and became smelly, no maggots were born. He concluded that maggots were transformed from the eggs laid by flies on the meat.

The citrus fruit fly has one generation per year, and the pupae overwinter in the soil.

Adults appear in late April, peak in early May, enter orchards from June to mid-July to lay eggs, peak in mid-June, hatch as larvae from July to September, and cause fruit borer damage. The affected fruits fall off in late September, and the larvae fall to the ground with the fruits, then fall off the fruits and pupate in the soil. Adults emerge from the soil at noon on sunny days. Adults lay eggs in the navel of the fruit, where there is a small puncture hole, and the fruit peel turns from green to yellow. Shady and humid orange orchards and orange orchards with many nectar sources are severely damaged by it. The citrus fruit fly is mainly spread through water flow and the transportation or carrying of insect fruits, and can also be spread through the migration of adults and a small number of pupae carrying soil and seedlings. Adults have strong flying ability and can fly up to about 400m, and can spread by themselves.
