To this end, the two closely related species Eisenia andrei and Eisenia fetida have been recommended by the Organisation for Economic Co-operation and Development since 1984 for toxicity testing of chemicals in soil environments. Hortensis worms are typically less than 5cm long, whereas veneta are usually significantly longer than this. It is a quick breeder and a good composter (makes plenty of castings). Veneta is a large chunky worm with distinct striping. Much sought after for fishing bait, as it can tolerate near freezing water and is one of the few “earthworms” suitable for salt water fishing. However, it is not a legal authority for statutory or regulatory purposes. The Eisenia fetida is the scientific name for the most common composting worm that is known best as the red wiggler worm. All specimens were cultured in the laboratory under controlled conditions and growth, maturation, cocoon production, hatching success, and the number of hatchlings were compared. Worms can live between 1 ° C and 33 ° C. The optimal temperature is between 15 ° and 25 ° …

Red wigglers are recommended by most vermicomposting experts, as they have some of the best appetites and breed very quickly. E. andrei had a higher cumulative cocoon production. Often times it is called by other names such as; composting worm, red worm, manure worm, tiger worm, trout worm and they are other names as well. On the outside of the red wiggler worm is the cuticle. The saddle-shaped clitellum covers 6-8 segments.

Bouche (1972) gave the uniformly pigmented worm the new subspecific name Eisenia fetida andrei. Jorge Domı´nguez , Alberto Velando, Alfredo Ferreiro Departamento de Ecoloxı´a e Bioloxı´a Animal, Universidade de Vigo, E-36200 Vigo, Spain Received 25 June 2004; accepted 23 August 2004 Summary The second most common worm is Eisenia hortensis. 6 Earthworms are, however, less evident research subjects in … The best type of worms for your composter is the Red Worm (Red Wiggler). E. andrei produced higher numbers of hatchlings per cocoon. Falling into the genus “anulus,” meaning “ring” in Latin, the Eisenia fetida has up to 120 circular rings.

Hortensis is a smaller thinner worm without distinct striping. Survival of earthworms in the environment depends on their ability to recognize and eliminate potential pathogens.

The results showed some differences between the two “forms”. Both "forms" have a mean length of 60-120 mm, a diameter of 3-6 mm and a segment number varying between 80 and 120. Specimens of locally occurring Eisenia fetida were compared with specimens of E. fetida and E. andrei obtained from France. Jorge Domínguez y Marcos Pérez-Losada (2010) Eisenia fetida (Savigny, 1826) y Eisenia andrei Bouché, 1972 son dos especies diferentes de lombrices de tierra. In Annelida, only three whole genomes, a marine polychaete (Capitella teleta), a freshwater leech (Helobdella robusta) and Eisenia fetida, have been sequenced 14,15,16. it prefers to live in compost or leaf litter rather than mineral soils. Buy this standard This standard was last reviewed and confirmed in 2018. These 2 species are very close and live in similar conditions. The Red Worm Body. The results show that the biology of the two species/forms is similar. Apart from the difference in pigmentation the two forms cannot be distinguished. Like its sibling species, it is epigeic, i.e.

Therefore this version remains current. Eiseinia Fetida and Eisenia Andrei are the most common worms for vermicomposting in Europe and temperate regions. In the earthworms Eisenia fetida and Eisenia andrei, immunity is also supported by the humoral factors lysenin and fetidin [40,41], the modes of antibacterial action of which are not fully understood [40,42].

Are Eisenia fetida (Savigny, 1826) and Eisenia andrei Bouche´ (1972) (Oligochaeta, Lumbricidae) different biological species? This work is aimed to compare the innate defense mechanisms of two closely related earthworm species, Eisenia andreiand Eisenia fetida, that inhabit substantially different ecological niches. Hortensis worms are smaller than Eisenia fetida and Eisenia andrei… Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. Their voracious appetites, medium size, and heartiness make them ideal composting worms. Although the local worms resembled E. andrei in appearance their cocoon production rate resembled that of E. fetida from France.

Eisenia andrei is a close relative of the 'brandling' or 'tiger' worm Eisenia fetida. The earthworm species (or composting worms) most often used are red wigglers (Eisenia fetida or Eisenia andrei), though European nightcrawlers (Eisenia hortensis or Dendrobaena veneta) could also be used.
