Perionyx excavatus and Eudrilus eugeniae in all Observations on the biology of Drawida nepalensis, Metaphire houlletiand Perionyx excavatuswere made, which were reared in cow manure and oak litter under laboratory conditions over a period of 150 days. Each of the four earthworm species differed considerably in terms of responses to and tolerance of different temperatures. They are all considered lower classifications of earthworms. The life cycle of this species is presented diagrammatically. The effect of ECF on cell cycle analysis and mechanism of cell death have also been investigated. Eudrilus eugeniae (Kinberg). The moisture requirements of P. excavatus were studied in cattle manure (particle size 500–1000 μm) at 25°C by exposing the worms to different, but constant moisture levels.
