Reproductive potential of the earthworm Eisenia foetida.

摘要: Regression equations are provided for the earthworm Eisenia foetida with respect to age at which 50% of population became clitellate 25° C in relation density activated sludge and horse manure. progeny per cocoon versus weight cocoon, parent; from these an equation is derived relative worm weight. given on (a) number cocoons produced adult onset adulthood median peak production cocoons, 10 weeks, weeks 27 (b) between ages 5 weeks. From a family (c) giving density. two families generated ascent to, descent from, week Data also reproduction terminates density, optimum reproduction, hatchability.
