EUDRILUS EUGENIAE PDF

If you are familiar with red worms one of the things you will immediately notice about the ANC is how large and muscular it is compared to the redworm. You may also be surprised at the large size of their castings. African night crawlers produce absolutely huge castings. There are some things you need to know before you try out African night crawlers so read up on the breed here on our ANC page. It is also reported that ANCs like to crawl and explore. And plump up they will; ANCs make excellent bait worms.

E-mail: anandharaj49 gmail. The important parameters such as cocoon production, hatchlings, total biomass and length of the earthworms were measured. The cocoon production was started at after 30 days and hatchlings were released after 45 days. Eudrilus eugeniae lives on the surface layer epigeic of moist soil and are also found wherever organic matter is accumulated Bouche, It is nocturnal and lies in the surface layer during the day.

The worm is reddish brown with convex dorsal surface and pale white, flattened ventral side. The clitellum is paler than the rest of the body. The adult worms are about cm in length, mm indiameter, consist of about segments and weigh mg of maximum individual biomass Viljoen and Reinecke, The rate of growth in oligochaetes is relatively proportional to nutritional level. According to Viljoen and Reinecke and the first indication of clitellum development appeared between days; worms with fully developed clitellum copulated readily.

The cocoons of Eudrilus eugeniea have an irregular oval shape and are sharply pointed with fibrous tips at the two ends. The cocoons are soft and grayish-white in colour immediately after formation,but harden rapidly with the colour changing to orange brown. Finally, the cocoons become dark-brown in colour immediately before hatching. The mean length of the cocoon is 6. A mean production of 1. Incubation period of Eudrilus eugeniea cocoon was Reinecke and Viljoen, Upon emergence,the hatchlings have a pink yellowish to red colour, with the hinder most segments still not fully differentiated.

The studies on growth, reproduction and life cycle of the wide spread Indian megascolicid worm, Lampito mauritii one among the four endemic species are very scanty. It can withstand wide range of temperature, soil moisture and various other physical factors Kale, and with wide choice of habitats and food preferences it has the highest frequency of distribution Kale and Bano, Only cocoon morphology, hatching and emergence pattern in this worm have been studied by Bhattacharjee and Chaudhuri A thorough understanding of the reproductive biology and growth of a worm is a pre-requisite before subjecting the worm to any experimentation in the laboratory and more particularly in the agro-industrial practices.

Over 10, species of earthworms exist around the world and only 31 described species of earthworms inhabit Thailand Gates, The culture of worms on a large scale is in high demand for the production of both protein and biofertilizer. In every region of the world, many species of earthworm are cultured namely Eisenia fetida,Lumbricus terrestris, Perionyx excavatus and Eudrilus eugeniae in all part of the world.

Introduced species are commonly found over a large area of tropical Asia, namely, the blue worm or Indian worm Perionyx excavates , red worm Pheretima peguana and earthworm from Lao P. However, the AF earthworm E. Reproduction by cross fertilization in majority of the species of earthworms but parthenogenesis also occurs in few. During copulation two worms come together in opposite directions, with the ventral surface attached to each other in such a way that the spermathecal openings touch each other.

The seminal grooves carry the seminal fluid from the male pores to the clitellar region and enter the spermathecae of the partner worms. In general like Eisenia, Lumbricus, Dendrobaena, Dedeodrilus, Aporrectodea and Octalasion sperms are transferred through spermatophore. After copulation the clitellum produces cocoon.

The cocoon contains ova, aluminous fluid and spermatozoa. The cocoon morphology varies among the different species of earthworms; it is spherical, lemon shaped or oblong with pointed tips. They may be white, yellow or brown, the color changes from yellow to brown during the incubation time. Immediately after laying they are white or yellow and gradually turn into brown as development proceeds.

The rate of hatching varies between species Stephenson, In recent times, morphological characters still are used to characterize earthworm species. Stephenson reported that the genital system is much more conservative and resistant to evolutionary change than the somatic system. Population dynamics, productivity and energy flow in earthworms cannot be fully understood unless the life cycle of the earthworm is known.

Studies on the life cycles of earthworms are also necessary for effective vermiculture. Hence the present study is aimed to study the life cycle pattern of the earthworm Eudrilus eugenieausing cow dung as a substrate.

African Nightcrawlers

In the study of reproductive system, 2 pairs of testicles in the lobe form are found at the posterior faces of the 10th to 11th segment and 11th to 12thsegment septa, 2 pairs of large seminal vesicles are on 11th and 12th segments and the prostate gland is in the form of euprostate which looks like finger. Anatomy and life cycle of Eudrilus eugeniae. Eudrilus eugeniae Kinberg Eudrilus eugeniae is a species of earthworm native to tropical west Africa and eygeniae widespread in warm regions, both wild and under vermicompostalso called the African night crawler.

African Night Crawler

The African Nightcrawler has a uniform purple-grey sheen. Maximum weight can be achieved in weeks. The African Nightcrawler has been a favorite fishing worm due to tis size and does not need to be refeigerated like the Canaidan Nightcrawler. The African Nightcrawlers are excellent vermimcomposting worms, that are perfect for home vermicomposting and composting fibrous material such as leaves.
