20.3.3.2 Effect on the Earthworm Reproduction
The cocoon production by Eisenia fetida as a measure of the earthworm reproduction ability at different doses of MP 2% dust a.i. is shown in Fig. 20.5. The cocoon
production in a period of 4 weeks was highest in the control reactors with an average
production of 9.33 Æ 1.53 cocoons in each reactor. The earthworms exposed to MP
