“…Also, an endosymbiont for E. eugeniae has been reported [ 27 ]. The significance of the presence of pathways for secondary metabolites’ metabolism was exemplified by the studies on improved reproduction success of E. eugeniae in vermibeds supplemented with organic plant materials [ 28 , 29 ]. The worm was reported to be used in the bioremediation of petroleum hydrocarbons [ 30 ].…”

Background: Earthworms are annelids. They play a major role in agriculture and soil fertility. Vermicompost is the best organic manure for plant crops. Eudrilus eugeniae is an earthworm well suited for efficient vermicompost production. The worm is also used to study the cell and molecular biology of regeneration, molecular toxicology, developmental biology, etc., because of its abilities like high growth rate, rapid reproduction, tolerability toward wide temperature range, and less cost of maintenance. Objective: The whole genome has been revealed only for Eisenia andrei and Eisenia fetida. Methods: In the present work, we sequenced the genome of E. eugeniae using the Illumina platform and generated 160,684,383 paired-end reads Results: The reads were assembled into a draft genome of size 488 Mb with 743,870 contigs and successfully annotated 24,599 genes. Further, 208 stem cell-specific genes and 3,432 non-coding genes were identified.

“…To this may be added the very high rate of nitrogen in rabbit and cattle manure [1]. According to [11], Eudrilus eugeniae grows well and produces more cocoons when fed on a substrate rich in nitrogen. Similarly, [5] shows that E. eugeniae grows quickly when it is in cocoa powder containing 3.6 % of nitrogen than in the oat flake which contains only 1.92 %.…”

Developing countries must, in order to support agriculture, integrate available natural resources and promote management of livestock waste. Therefore, the potential of earthworms to decompose organic waste must be exploit : vermicomposting. Thus earthworm Eudrilus eugeniae was cultured in 4 simples treatments and 6 mixed manure treatments. These treatments are combination or not of manure of cattle, cavies, rabbit and poultry. Each treatment has undergone 3 repetitions. The experiment lasted 12 weeks. pH, numerical productivity of E. eugeniae and biomass of E. eugenia have been determined. The results showed that all treatments containing rabbit manure have a final pH close to 7 (neutral pH) with the exception of MG +MR treatment. Those based on poultry or guinea-pig manure and the control range between 5 and 6.5 and are therefore more acidic. The average density and the earthworm biomass of the MC + MR treatment respectively 2889 ± 333 ind./ m2 and 397.22 ± 234.44 g / m2 are different from other treatments. the manure mixture is a privileged environment for Eudrilus eugeniae. It provides a significant biomass of earthworms that can be used in fish farming or in the diet of monogastric animal feed.

“…The fluctuations in the cocoon production may be because of the different composition of the organic Tamire (2017) observed that the hatching success of P. excavates in response to N-content in the substrate was very high. The growth and reproduction of earthworms directly depends upon the organic matter and N content of the soil (Kabi et al 2020). In the present study, growth and reproduction were recorded as very poor in Treatment A, where soil and autumn leaves were taken in a ratio of 3:1.…”

The present study evaluated the effect of autumn leaves as a food source on the growth and reproductive performance of Eisenia foetida. Three treatments, A, B, and C, each having five replicates, were designed in a total of 15 pots. For bedding soil, manure and autumn leaves were used in different ratios. The soil-to-leaf ratio in Treatment (A) was 3:1, the soil-to-manure-to-leaf ratio in Treatment (B) was 1:2:1, and the manure-to-leaf ratio in Treatment (C) was 3:1. Treatment C showed the most growth (Specific Growth Rate %, live weight gain, % gain in body weight and survivability) and was followed by Treatment B. All these parameters were recorded, with minimal in Treatment A, where soil and autumn leaves are mainly used in bedding. Also, high reproductive potential was recorded in treatments C and B as compared to A. Hence, the autumn leaves are good for the growth and reproduction of E. foetida provided the bedding has all the other nutritional requirements like manure and nutritive soil.
