CATDOLL : CATDOLL: How often can earthworms reproduce? (How often can earthworms reproduce?)

1. How often do earthworms reproduce?

Earthworms can lay eggs once every three months.

1. Earthworms are commonly known as qu yu, and are called earthworms in traditional Chinese medicine. They have high economic value. Earthworms are the "strongmen" who cultivate the soil. Through their activities, they loosen the soil and strengthen the aggregate structure, thereby promoting the growth of crops. Earthworms have a wide range of food habits. Many organic substances that pollute the environment can be used as their food, so they are used to treat organic waste and purify the environment. Earthworms also have the characteristics of high reproduction rate and rich protein content, so breeding earthworms is also an effective way to solve the problem of animal protein feed. In addition, earthworms have high medicinal value and have the functions of antipyretic, antispasmodic, antiasthmatic, antihypertensive, diuretic and meridian dredging.

2. Earthworms do not have special respiratory organs, they breathe through their skin, so the body of earthworms must be kept moist. Although earthworms have temporary tolerance to different humidity conditions, in order to survive, they sometimes move to a suitable environment, and sometimes reduce water consumption by hibernation, diapause, and lowering metabolic intensity, but this will seriously affect their growth and economic benefits.

2. How often do red earthworms reproduce?

Red earthworms reproduce about once every three months. They will lay eggs 7-8 days after mating and bury the eggs in the soil. The eggs will hatch in 18-21 days. Earthworms are hermaphrodites, but require cross-fertilization. During mating, earthworms secrete mucus to make the abdomens of both parties stick together, and then discharge semen from the reproductive pores into the other party's spermatheca. When the eggs mature, they are discharged into the cocoon. After the cocoon is fertilized, the earthworms lay them in the soil.

3. How long does it take for the earthworms you buy to reproduce?

Earthworms can lay eggs once every three months. Earthworms are hermaphrodites, mate once and reproduce for life, are disease-free, have a very high reproduction rate, and live 1 to 3 years. Earthworm eggs hatch after 18 to 21 days, and grow to sexual maturity after about 60 days.

Adults begin to lay eggs 5 to 8 days after mating, and then lay one egg every other day. The first three eggs hatch 1 to 3 earthworms each, and the subsequent eggs hatch 4 to 7 earthworms each. After 100 days, the growth of earthworms slows down, so harvesting earthworms at 90 to 100 days is the most profitable.

Earthworms all develop directly. The fertilized egg forms a hollow blastocyst through unequal complete cleavage, forms a gastrula through invagination, forms a mesoderm band from terminal cells, and forms a body cavity through scission.

Growth habit:

Generally speaking, the activity temperature of earthworms is 5-30℃, they enter a dormant state at 0-5℃ and die below 0℃. The optimum temperature is around 20-27℃, which is also the optimum temperature for earthworm cocoon eggs. They stop growing at above 32℃ and die at above 40℃.

Earthworms use their skin to breathe, so their bodies must remain moist. Water accounts for more than 75% of their body weight. Preventing water loss is the key to their survival. Therefore, the humidity of the feed should be kept at around 70%.

Earthworms grow best in a pH range of 6-8 and produce the most cocoons.

4. How many times a year do earthworms reproduce?

Sexually mature earthworms can mate up to 12 times in a year.

Under suitable conditions, sexually mature earthworms can reproduce once a month. The newly laid eggs are transparent, oval or spindle-shaped, and initially milky yellow, turning red in about 7 days, and hatching into small earthworms in about another 7 days.

The time it takes to develop varies from species to species, ranging from one week to several months. Pheretima requires 2-3 weeks, while Lumbricus requires 12-13 weeks. The life span ranges from one year to several years. Some Lumbricus can live up to 6 years, and generally reach sexual maturity after one year.

5. How often do earthworms reproduce?

3 months

Earthworms can lay eggs once every three months. Earthworms are hermaphrodites, mate once and reproduce for life, are disease-free, have a very high reproduction rate, and live 1 to 3 years. Earthworm eggs hatch after 18 to 21 days, and grow to sexual maturity after about 60 days;

6. How often do earthworms reproduce?

The growth cycle of earthworms is from the laying of egg cocoons to the development and maturation of earthworms. The growth and development of earthworms is closely related to environmental conditions. The most suitable growth temperature for red earthworms is around 25℃. Earthworms are hermaphroditic animals, but they must mate with different sexes. Sexually mature earthworms (i.e. earthworms with reproductive rings) lay eggs one week after mating. However, the frequency of egg laying is closely related to temperature. When the temperature is below 10℃, it takes about 35 days to lay one egg; when the temperature is between 18 and 25℃,

7. In which month do earthworms reproduce?

The peak period of earthworm reproduction depends on the region: January, February, March, April, May, October, and November in the south, and April, May, June, September, and October in the north. They like darkness, humidity, quietness, warmth, sweet and sour food, and living alone. They are afraid of light, shock, immersion, salt, spiciness, cold and heat.

The activity temperature of earthworms is in the range of 5-30℃. They enter a dormant state at 0-5℃ and die below 0℃. The most suitable temperature is about 20-27℃, at which they can grow, develop and reproduce well. At 28-30℃, they can maintain a certain growth; growth stops at above 32℃; activity is sluggish at below 10℃; they die at above 40℃, and the optimum temperature for earthworm cocoon hatching is 18-27℃. It can be seen that the highest lethal temperature of earthworms is lower than that of other invertebrates. It is best to have a breeding farm indoors in the southern region. In summer, ventilation and moisture retention are ensured, and in winter, just closing windows to keep warm can produce normally throughout the year (the temperature here refers to the temperature of the base material, because the temperature of the air is different from the temperature of the base material. For example, when the air temperature is 0℃, the base material temperature is about 12℃; when the air temperature is 38℃, the base material temperature is only about 28℃, because the manure contains extremely high moisture).

8. How often do earthworms reproduce, and when is the peak reproduction season?

1. Earthworms generally reach sexual maturity and begin to reproduce in about 2-3 months. The specific time depends on the species of earthworms.

2. Under the environment with average room temperature of 21℃, it takes about 24-28 days for Eisenia fetida to hatch from cocoons to larvae, and about 30-45 days for larvae to become adults. It takes about 5-10 days for adults to lay cocoons after mating. The generation interval is about 59-83 days.

3. In the southern region, the earthworms are most active in breeding in January, February, March, April, May, October, and November. In the northern region, the earthworms are most active in breeding in April, May, June, September, and October.
