Earthworms are known to be hermaphrodites, each individual produces sperm and eggs, the reproductive system consists of male and female organs arranged in the ventral region between segments 9-14.
▶ Each individual after copulation produces coconuts in variable number, from each cocoon worms emerge after a period of 2 to 4 weeks. Maturity occurs between 40 - 50 days after hatching. The adult stage is characterized by the presence of the clitellum.
Earthworm reproduction takes place throughout the year. Among the main factors influencing capsule reproduction are: species, density, quality of food, temperature and humidity of the medium.
If the worm is periodically transferred to fresh food, the production of capsules and fecundity increase, because ideal biological conditions are generated for their multiplication.
This can decrease as the rearing time passes, because the food reserves decrease, the most favorable humidity is 80% and the optimum temperature is 20° C.
