The mean incubation period of cocoons produced by single worms was 20,4 days with a mean hatching success of 40,4%.

Life cycle experiments were carried out in the lab Department of Soil Science with average room temperature of 21-28°C and 60 to 80% moisture of the culture media during 15 February to 10 June 2018. Maturation was attained at the age of approximately 21 days. /Length 912 Reinecke, S.A.

Outside of Iquitos, in the Loreto area, temps are fairly steady year round in the mid-90’s, with lows in the 70’s. The incubation period of cocoons of P.excavatus was ±19 days. As a rule only one worm hatched per cocoon. Ten einde die konsep van vermikultuur as biotegnologie in afvalbeheer en proteïenproduksie te ondersoek, is die lewensiklus van die vermikomposterende erdwurmspesie Perionyx excavatus bestudeer.

Pheretima, Perionyx excavatus, Glossoscolecidae, Acanthodrilidae, and Eudrilidae are also species of earthworms that you may not know of just by looking at their name. Epigeic earthworms can significantly hasten the decomposition of organic matter, which is known to be mediated by gut associated microflora.

The life cycle and the potential of Perionyx excavatus for breaking down organic wastes and turning it into rich soil amendment has been documented by various authors under controlled conditions (Kale et al 1988; Reinecke and Hallatt 1989, I-Iallatt et al 1990; Reinecke et al 1992; I-Iallat et al 1992). Present study deals with cocoon biology of tropical epigeic earthworm Perionyx excavatus (Perrier), Perionyx ceylanensis (Michaelsen) and Eudrilus eugeniae (Kinberg). Perionyx excavatus (Perrier), and . In order to exploit the concept of using vermiculture as biotechnology for waste control and protein production, the life cycle of the vermicomposting species, Perionyx excavatus, was studied. excavatus have been identified in Hawaii; how long it has been here is not known.
