Vermicomposting of different forms of water hyacinth by the earthworm Eudrilus eugeniae, Kinberg
Bioresource Technology, 2002Six-month long trials were conducted on different vermireactors fed with one of the following forms of water hyacinth: (a) fresh whole plants, (b) dried whole plants, (c) chopped pieces of fresh plants, (d) 'spent' weed taken from reactors after extracting volatile fatty acids (VFAs), (e) precomposted fresh weed and (f) precomposted spent weed.

Uptake and toxicity of copper and zinc for the African earthworm, Eudrilus eugeniae (Oligochaeta)
Biology and Fertility of Soils, 1996Growth rate change in earthworms is considered to be a suitable endpoint when determining sublethal effects. In this study we evaluated growth and maturation in the vermicomposting earthworm speciesEudrilus eugeniae as marker of sublethal toxicity of copper and zinc. We also compared routes of uptake.

Unique phenotypes in the sperm of the earthworm Eudrilus eugeniae for assessing radiation hazards
Environmental Monitoring and Assessment, 2012The earthworm, Eudrilus eugeniae is a segmented worm. It has two pairs of testes whose cells are highly proliferative. It was found that the earthworm, which is irradiated with X-ray, shows the following phenotypic changes in its sperm: fragmented acrosome in the head, break in the tail, and the appearance of zigzag sperm tail.

Acute Toxicity and LC50 Values of Chlorpyrifos on Eudrilus eugeniae
BIOINFOLET - A Quarterly Journal of Life SciencesAbstractPresent study evaluates acute toxic effects of chlorpyrifos on earthworm ( Eudrilus eugeniae ) under laboratory conditions. Acute toxicity bioassays was performed following OECD ( 1984) guideline 207 using artificial soil. The LC50 values were determined after 7 and 14 days of exposure.

Acute toxicity and LC50 determination of roundup on Eudrilus eugeniae
BIOINFOLET - A Quarterly Journal of Life SciencesAbstractPresent study was undertaken to assess effect of Roundup on earthworm, Eudrilus eugeniae. The values for LC50 were determined over 7 and 14 day exposure periods. Earthworms were exposed to concentrations ranging from 0.01 to 1000 ppm in artificial soil.

EFFECT OF CuSO4 AND ZnSO4 ON BIOCHEMICAL PARAMETERS OF EARTHWORM, Eudrilus eugeniae
2021Heavy metals are hazardous to soil invertebrates at high concentrations. Earthworm biochemical responses can serve as early signs of soil contamination. The effects of heavy metals such as CuSO4 and ZnSO4 on biochemical parameters such as protein, lipid and glycogen in the earthworm, Eudrilus eugeniae were investigated in present study.
