“…To better know E. eugeniae and to develop its lombriculture, several studies were carried out and aimed at describing the internal anatomy (DaDong et al, 2007;Butt and Grigoropoulou, 2010), the cycle of reproduction (Parthasaeathi, 2007;Sivasankari et al, 2013), growth and reproduction in various substrates (Coulibaly and Zoro Bi, 2010;Tahir and Hamid, 2012;Nayak and Sahu, 2013), and reproductive organs (Vijaya et al, 2012;Moraes et al, 2012). Lombriculture of E. eugeniae was carried out in several countries of the tropical area (Francis et al, 2003;Coulibaly and Zoro Bi, 2010;Tahir and Hamid, 2012).…”

The objective of the current study was to compare the effect of cow dung and manure of laying hens, associated to one of the three carbon substrates, on weight and population of this worm. Each substrate was sown with twenty (20) adult worms, 0.7 to 1 g weight. The weight of worms was collected at the beginning and at the end of breeding. The number was collected weekly until 60 days of breeding. The average number of worms was multiplied by 2.38 (60±6.78 in cow dung, 40±6.81 in manure of laying hens and 43 ± 8.23 in control). The average weight of worms was 27.19±1.21, 24.41±1.20, and 22.41±1.44 g, respectively. These results suggest that cow dung is better than manure of laying hens for vermiculture of E. eugeniae.

“…The different amounts of corn from 75 th day had a great reduction of the population of earthworms and considerable increase of larvae and insects accompanying the increased amounts of ground corn in the substrates because starch undergoes enzymatic hydrolysis breaking molecular bonds and producing glucose molecules, what becomes food for fungi, bacteria and insect larvae, confirming the information by Cenciani et al (2008). According to Moraes et al (2012) there is a rapid biological process of insect larvae on substrates of agricultural wastes that are rich in starch, turning them into protein and fat, producing the malodorous humus. This corroborates what we observed visually in our experiment.…”

Eudrilus eugeniae is a foreign species that is well adapted to captivity system adopted in Brazil. The objective was evaluate the productive and economic performance of earthworms in different substrates in two 100 days. In aim 1, the control substrate composed by cattle manure and forage grass (CMG) was supplemented with minerals (MM), soybean meal (SB) and ground corn (GC). The substrate containing GC was higher than in average weight (AW ) of 127% and average weight gain (AWG) of 332% when compared to CMG substrate, superior in 193% AW and 252% AWG when compared to MM and 251% AW and 403% AWG when compared to the substrate with SB. In aim 2, were used different amounts of GC in substrate. The production of the substrate that contained 5% GC was superior in 9%, 12% and 20% with regard to those that had a composition of 10%, 15% and 20% of GC, respectively. As for the difference between the costs and the benefits of each of the substrates, the 5% GC substrate showed a positive return of BRL$ 35.32 for each BRL$1.00 invested and an economic performance that was 205% superior to MM, the second best option among substrates. 5% GC performed better and more efficient and economically viable production of worms. RESUMO:Eudrilus eugeniae é a espécie exótica de minhoca que melhor se adapta aos sistemas de criação em cativeiro adotados no Brasil. Objetivou-se avaliar o desempenho produtivo e econômico das minhocas em diferentes fontes alimentares em dois ensaios de 100 dias experimentais. No Experimento 1, um substrato basal composto por fezes bovina e grama batatais (FBGB) foi suplementado com mistura mineral (MM), farelo de soja (FS) e grão de milho triturado (GC). O substrato contendo 5% de milho (GC) foi superior (P < 0,05) em peso médio e ganho de peso das minhocas em 127% e 332% ao tratamento controle FBGB, em 193% e 252% a mistura mineral e 251 e 403% ao tratamento contendo farelo de soja, respectivamente. No Experimento 2, foram usadas diferentes quantidades de GC no substrato. A produção do substrato que continha 5% GC foi superior em 9%, 12% e 20% em relação aos que tinham uma composição de 10%, 15% e 20% de GC, respectivamente. Na avaliação econômica da utilização dos diferentes substratos, o substrato GC apresentou retorno positivo de R$ 35,32 e maior retorno econômico relativo superior em 205% a MM (R$ 3,52). Observou-se retorno negativo de R$ -33,22 para o tratamento contendo 10% de GC, de R$ -12,36 para 15% de GC e R$ -39,98 para 20% de GC em relação ao tratamento contendo menor nível adicionado, considerando-se o custo dos ingredientes no mercado local aos 100 dias de avaliação. O tratamento com 5% de GC apresentou melhor desempenho sendo mais eficiente e economicamente viável à produção de minhocas.

Eudrilus eugeniae est un ver épigé d'origine africaine. Il est principalement rencontré dans les pays tropicaux et subtropicaux, et est utilisé dans les processus de lombriculture et de lombricompostage. Littérature. Le développement de l'utilisation et de l'exploitation du ver nécessite un approfondissement des connaissances s'y rapportant pour optimiser la production des vers et du lombricompost. Cette synthèse bibliographique a été initiée pour faciliter la valorisation agronomique de l'espèce au Gabon et améliorer les connaissances actuelles sur E. eugeniae. Elle pourrait faciliter l'élaboration d'une clé d'identification spécifique à E. eugeniae, à l'instar de celles qui existent pour d'autres espèces. Conclusions. La synthèse des connaissances disponibles sur le ver de terre E. eugeniae devrait faciliter son exploitation et sa valorisation dans les pays comme le Gabon où l'étude de ce ver de terre est récente. Mots-clés. Eudrilus, vermicompostage, morphologie, vermiculture, Gabon. Roles and morphological characteristics of the earthworm Eudrilus eugeniae. A reviewIntroduction. Eudrilus eugeniae is an aboveground African worm mainly found in tropical and subtropical countries and is used in the process of vermiculture and vermicomposting. Literature. The development of the production of this earthworm species requires a deepening knowledge of the species. This review aimed to facilitate the agricultural recovery of the worm in Gabon and improve the current knowledge on E. eugeniae. Finally, the development of a specific identification key for E. eugeniae is recommended. Conclusions. Further investigation regarding the geographical distribution of this worm in the equatorial zone, where it was recently described, must also be considered. This review of the available knowledge on the earthworm E. eugeniae should facilitate its use and its valorization in countries such as Gabon, where knowledge of this worm is recent.
