CATDOLL : CATDOLL: How long does it take for fly maggots to lay eggs?

1. How long does it take for maggots to lay eggs?

The life of a fly can be divided into four stages, starting from the mating and egg-laying of adult flies, through the process of egg->larvae (maggots)->pupa->adult flies. This process only takes about 10 days and can be shortened when the temperature is high.

The length of the pre-oviposition period of female flies (i.e. the time from emergence to the first egg laying) is closely related to the ambient temperature: it is an average of 9 days at 15°C, only 1.8 days at 35°C, and no eggs can be laid at temperatures below 15°C.

I hope Zhanying's answer is helpful to you.

2. Do flies lay eggs in summer?

Flies lay eggs and reproduce regardless of season. As long as the temperature is suitable, they can lay eggs and reproduce.

Under suitable temperature, male houseflies can reach sexual maturity and mate 18 to 24 hours after emergence and female houseflies can reach sexual maturity and mate 30 hours after emergence. Mating usually takes place between 5:00 and 7:00 in the morning. Sensitive sense of smell, sex pheromones and vision are all important factors that promote mating between male and female flies. A mating pair of houseflies can stay in one place for a long time, crawling together, flying together, and the effective mating time can be up to 1 hour. Most houseflies only mate once in their lifetime. The semen of male flies can be stored in the spermathecae of female flies for a long time, stimulating egg laying, and the eggs can be continuously fertilized for 2 to 3 weeks without mating with another male fly. This is rare in other insects. This is the important reason why flies have strong fertility.

The peak period of egg-laying is from 17:00 to 19:00 every day. The length of the pre-oviposition period of female flies (i.e. the time from emergence to the first egg-laying) is closely related to the ambient temperature: at 15°C, it takes an average of 9 days, at 35°C, it only takes 1.8 days, and it cannot lay eggs when the temperature is below 15°C. After mating, female flies often crawl into breeding crevices such as human and animal feces, extend their ovipositors and lay eggs deep in the breeding organisms to ensure that the eggs are fully protected.

Flies have amazing fertility. It has been observed that houseflies in the laboratory lay about 100 eggs per batch, and one female fly can lay 10-20 batches of eggs, with a total of 600-1000 eggs. In nature, each female fly can lay 4-6 batches of eggs in its lifetime, with an interval of 3-4 days between each batch, and each batch of about 100 eggs, with a lifetime egg production of 400-600 eggs. Even in North China, houseflies can reproduce 10-12 generations a year. According to the most conservative estimate, each female fly can produce 200 offspring, so 100 female flies only need 10 generations to reproduce a total of 200 trillion flies!

3. Why does soy sauce get infested with bugs?

One of the reasons for "worms in soy sauce" is the laying of flies' eggs. However, after scientific experiments, it was found that this conclusion is not completely accurate. The main cause of worms in soy sauce is the soy sauce flax fly, which adopts a special "ovoviviparous" method. Their reproduction method allows them to lay worms directly around the mouth of the soy sauce bottle. Professor Qiu Xuehong of the Guangdong Institute of Biological Resources Application found that the eggs of ordinary flies will not hatch at all in high-salt soy sauce foods, and improper storage of soy sauce bottles after opening the bottles allows soy sauce flax flies, which like high protein and amino acids, to find opportunities to lay worms and grow on the soy sauce bottle caps, becoming the real culprit for worms in soy sauce. According to the latest scientific research findings, the antennae of the soy sauce flax fly become "detectors" for finding proteins and amino acids, which is also the reason why soy sauce is prone to worms after opening.

How to store soy sauce 1. In case of moldy soy sauce due to warmer weather, mothers can pay more attention in daily life and never mix raw water into the bottle of soy sauce. However, if the soy sauce is moldy, you don’t have to throw it away without thinking. As long as it is handled properly, it can still be used. Treatment method: Boil the soy sauce and then seal it. 2. Put a little sesame oil in the container of soy sauce to cover the surface with a thin layer of oil film, or put a piece of scallion, or a few garlic cloves, or add a little soju in the bottle, which can also play a role in preventing mold. Summer is a season prone to mold, so in addition to preventing soy sauce from getting moldy, mothers should also properly preserve some canned enoki mushrooms and miscellaneous vegetables, which can be placed in the refrigerator.

4. Do flies get killed faster or do they reproduce faster? Which means can all the flies be killed?

Crabs have eyes on both sides, so they can see both sides, so they can walk sideways. For example, human eyes can squint to both sides, but cannot see completely, so people cannot walk sideways.

5. Can anyone tell me whether flies reproduce once a year or have a hibernation period like snakes? It would be best if you could tell me how long they can survive. Thanks.

Female flies live longer than male flies, with a lifespan of 30 to 60 days, and under laboratory conditions, up to 112 days. In low-temperature wintering conditions, flies can live for half a year.

Under suitable temperature, male houseflies can reach sexual maturity and mate 18 to 24 hours after emergence, and female houseflies can reach sexual maturity and mate 30 hours after emergence.

The peak period of egg-laying is from 17:00 to 19:00 every day. The length of the pre-oviposition period of female flies (i.e. the time from emergence to the first egg-laying) is closely related to the ambient temperature: at 15°C, it takes an average of 9 days, at 35°C, it only takes 1.8 days, and it cannot lay eggs when the temperature is below 15°C.
