Abstract

Rearing earthworms under laboratory conditions is now essential due to developments in ecotoxicology and soil restoration. A review of such research for temperate, soil dwelling species is presented. Critical abiotic and biotic factors including soil moisture, temperature and pH, earthworm density and species composition are considered. Optimal values are provided for 4 species (Allolobophora chlorotica, Aporrectodea caliginosa, Aporrectodea longa and Lumbricus terrestris). Guidelines are offered for culture of these and other soil dwelling species.
