Notes

Acute and sublethal toxic effects of the insecticides parathion and propoxur on earthworms were determined in laboratory and field tests. In acute toxicity tests according to OECD Guideline No.207 Aporrectodea caliginosa SAV. and Aporrectodea longa UDE were more susceptible than Eisenia fetida SAV. In prolongaed toxicity tests with E. fetida parathion significantly reduced the number of cocoons and surviving juveniles whereas propoxur reduced the number of suviving juveniles only. Results from these laboratory tests were used to explain species-specific effects of the insecticides in a field study.
