Question

Which of the following cannot be established properly in the field?

(a) Eisenia foetida

(b) Perionyx

(c) Epifilis

(d) Aneciques

The question was posed to me at a job interview.

This interesting question is from Aerobic Treatment of Solid Wastes in section Biotechnology for Solid Waste Management of Environmental Biotechnology

Answer 1

The correct choice is (a) Eisenia foetida

The best explanation: Perionyx, Epifilis, Aneciques cannot be used for Indian conditions and are often properly established in the field, but are the most common species of earthworms used as Vermicomposting earthworms worldwide in comparatively lower temperature conditions, whereas, Eisenia foetida is the best variety of earthworm and can process the organic wastes very efficiently but they cannot be established properly in the field.
