CATDOLL : CATDOLL: Fly breeding cycle, is the reproductive capacity strong?

The life of a fly is divided into four stages: egg stage, larvae, pupae, and adult fly. The egg stage is about 8-24 hours, the larvae stage is generally about 3-6 days, the pupae stage is generally about 3-7 days, the life span of male flies is generally about 7 days, and the life span of female flies is generally about 30-60 days. Flies have a strong reproductive capacity because after mating with female flies, the male fly's semen can be stored in the female fly's spermatheca for a long time, stimulating the female fly to lay eggs, and there is no need for subsequent mating.

1. Fly breeding cycle

The life of a fly is divided into four stages: egg stage, larvae, pupae, and adult flies (the duration of each stage is mainly related to temperature and humidity). The specific time of each stage is as follows:

1. Egg stage

(1) The development time of eggs is generally 8-24 hours.

(2) When the temperature is 22°C, the incubation time of the eggs is about 20 hours. When the temperature is 25°C, the incubation time of the eggs is about 16-18 hours. When the temperature is 28°C, the incubation time of the eggs is about 14 hours. When the temperature is 35°C, the incubation time of the eggs is about 8-10 hours. When the temperature is below 13°C, the eggs will not develop.

(3) When the relative humidity is about 75-80%, the hatching rate of eggs is the highest. When the relative humidity is below 65% or above 85%, the hatching rate of eggs decreases.

2. Larvae

(1) The larval stage generally lasts about 3-6 days.

(2) When the temperature is 34-40°C, the larval development period is about 3-3.5 days. When the temperature is 25-30°C, the larval development period is about 4-6 days. When the temperature is 20-25°C, the larval development period is about 5-9 days. When the temperature is 16°C, the larval development period is about 17-19 days. When the temperature is below 8-12°C or above 48°C, the larvae stop developing or die.

(3) The suitable humidity for 1-2 instar larvae is 61-80%, and the optimal humidity is 71-80%. The suitable humidity for 3-instar larvae is 61-70%. If it exceeds 80%, the larvae cannot develop normally.

3. Pupa Search Hall

(1) The pupal stage generally lasts about 3-7 days.

(2) When the temperature is 16°C, the pupal stage is about 17-19 days. When the temperature is 20°C, the pupal stage is about 10-11 days. When the temperature is 25°C, the pupal stage is about 6-7 days. When the temperature is 30°C, the pupal stage is about 4-5 days. When the temperature is 35°C, the pupal stage is about 3-4 days. When the temperature is below 12°C, the pupa stops developing. When the temperature is above 45°C, the pupa dies.

(3) The suitable humidity for pupal development is 45-55%. When the humidity is higher than 70% or lower than 15%, it will affect the normal emergence of pupae.

4. Adult flies

(1) The life span of male flies is shorter than that of female flies. Generally, the life span of male flies is about 7 days, while the life span of female flies is about 30-60 days. In the laboratory, the life span of female flies can reach 112 days.

(2) The life span of adult flies is related to temperature and humidity. When the temperature is 25-33°C and the humidity is 60-70%, the life span of adult flies is longer. When the temperature exceeds 45-47°C, the flies die.

2. Do flies have strong reproductive capacity?

1. Flies have extremely strong reproductive capacity.

2. Flies can mate about 1-2 days after hatching, and after mating, the male fly's semen can be stored in the female fly's spermatheca for a long time, stimulating the female fly to lay eggs (no need for subsequent mating), and fertilizing the fly eggs for 2-3 consecutive weeks.

3. A female fly can lay eggs 4-6 times in her lifetime, with each laying of about 100-150 eggs. The interval between each laying is 3-4 days, and she can lay 400-600 eggs in her lifetime. It is estimated that a female fly can produce 200 offspring and can reproduce 10-12 generations a year (in North China).
