MITRA* * Parasitology Laboratory, Department of Zoology, University of Kalyani, Kalyani-74I 235, West Bengal, India INTRODUCTION Soil animals may play a range of roles in vineyards. Decomposers (some of which are opportunistic herbivores) are important in nutrient dynamics, because by reducing organic matter to its constituents, they liberate nutrients usable by grapevines. Earthworms are only part of the complex of organisms termed "decomposers" in agroecology. As noted by Charles Darwin in his 1882 classic, The Fonnation of Vegetable Mould Through the Action of Earthworms with Observations on Their Habits (Werner, 1990), earthworms process huge quantities of plant litter and help to convert it into rich topsoil, liberating nutrients for renewed plant growth. More recent studies show that earthworms can help to reduce soil compaction, improving permeability and aeration. Earthworms do this through burrowing activities, ingestion of soil along with plant debris, and subsequent excretion of casts. Upon drying, these casts form water-stable soil aggregates. These aggregates are clumps of soil particles bound together by organic compounds, and their presence helps to improve soil structure, retain nutrients that might otherwise be leached, and reduce the threat of erosion (Lee, 1985). Earthworms are increasingly recognized as indicators of agro-ecosystem health and as important tools for ensuring soil improvement and efficient nutrient cycling. In India, due to continuous biodiversity surveys of earthworms number of new species IS increasing day by day, although in comparison to more than 3000 global species (Stephenson, 1923), the number of Indian species is far less (only 390). -

E-mail: [email protected] Received: 12 January 2016/Accepted: 17 January 2016/ Published: 31 March 2016 Abstract: Tubificids are aquatic oligochaete worms (F- Naididae, O- Haplotaxida, P- Annelida) distributed all over the world. The worms are very important as they are used as live food for fish and other aquatic invertebrates. A step was taken to identify the genera of tubicifid worms that exist in Mymensingh district, Bangladesh on the basis of some external features including the shape of their anterior (prostomium) and posterior end, number of body segment and arrangement of setae. The study result indicated the existence of three genera among the tubificid worms. These were Tubifex, Limnodrilus and Aulodrilus. All these three genera possessed a cylindrical body with a bilateral symmetry formed by a series of metameres. The number of body segments ranged from 34 to 120 in Tubifex, 50 to 87 in Limnodrilus, and 35 to 100 in Aulodrilus. In Tubifex, the first segment, with the prostomium, was round or triangular bearing appendages, whereas, in Limnodrilus and Aulodrilus, the prostomium without appendages was triangular and conical, respectively. -

This species was first described by German naturalist Fritz Müller in 1857 from Santa Catarina state of Brazil. It is commonly found in gardens, cropland and fallow lands. It tolerates wide range of climatic and edaphic factors due to its endogeic ecological category. P. corethrurus has high efficiency for organic matter assimilation and has ability to live in new habitat due to which it can survive even in very poor soil. The life cycle of this species is well documented and this species has economic importance due to its use in waste management. 1. Introduction There are total 505 earthworm’s species present in India; out of which 51 are exotic species [1, 2]. -
Chapter XXV —Class Oligochaeta
Chapter XXV —Class Oligochaeta (Aquatic Worms)- Phylum Annelida Oligochaetes are common in most freshwater habitats, but they are often ignored by freshwater biologists because they are thought to be extraordinarily difficult to identify. The extensive taxo- nomic work done since 1960 by Brinkhurst and others, however, has enabled routine identifica- tion of most of our freshwater oligochaetes from simple whole mounts. Some aquatic worms closely resemble terrestrial earthworms while others can be much narrower or thread-like. Many aquatic worms can tolerate low dissolved oxygen and may be found in large numbers in organi- cally polluted habitats. Aquatic worms can be distinguished by: (Peckarsky et al., 1990) • Body colour may be red, tan, brown or black. • Cylindrical, thin (some are very thin), segmented body may be upto 5 inches. • May have short bristles or hairs (setae) that help with movement (usually not visible). • Moves by stretching and pulling its body along in a worm-like fashion. Four families in the orders Tubificida and Lumbriculida are common in freshwater in northeastern North America: the Tubificidae, Naididae, Lumbriculidae, and Enchytraeidae. In addition, fresh- water biologists sometimes encounter lumbricine oligochaetes (order Lumbricina; the familiar earthworms), haplotaxid oligochaetes (order Haplotaxida; rare inhabitants of groundwater), Aeolosoma (class Aphanoneura; small worms once classified with the oligochaetes), and Manayunkia speciosa (class Polychaeta) in waters of northeastern North America. (Peckarsky et al., 1990). The two families, Naididae and Tubificidae form 80 to 100% of the annelid communi- ties in the benthos of most streams and lakes at all trophic levels. They range in size from 0.1 cm in Naididae to 3 or 4 cm in relaxed length in Lumbricidae, the family that contains the earth- worms. -
Two Aquatic Oligochaete Species, Dero Dorsalis and Allonais Pectinata (Annelida: Clitellata: Naididae), New to Korea

Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferronière, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.

Pune - 413 115 Maharashtra, India *E-mail address: [email protected] ABSTRACT In vermiculture, it is mandatory to keep the feed given to earthworm moist which will enable them to eat and procreate. Water is regularly sprinkled over the feed. The water mixes in the feed and oily content of earthworms body and slowly drains out from earthworm beds. The outgoing liquid is a concentrate with nutrients which is very beneficial for plants growth. This liquid is called vermiwash. The vermiwash is potential application in sustainable development for agriculture and biotechnology. This attempt deals with assessment the physico-chemical, nutritional and biochemical status of the vermiwash obtained using the popular composting earthworm species Eudrillus eugeniae (Kinb.) (Eudrilidae: Haplotaxida) and Lampito mauritii from three different leaf litters namely, Mango (Mangifera indica), Guava (Psidium guajava) and Sapota (Achrus sapota). The results showed substantial increase in the nutrient quality of the vermiwash produced with time in all of three cases. However, the vermiwash produced from guava leaf litter showed more content of electrical conductivity, magnesium, calcium, nitrite, phosphorus, carbohydrate, protein, lipid and amino acid compared with the vermiwash produced from the other two sapota and mango leaf litter by using the both earthworm species Eudrillus eugeniae and Lampito mauritii respectively. -

ABSTRACT. A reevaluation of South American oligochaetes produced 871 known species. Megadrile earthworms have rates of endemism around 90% in South America, while Enchytraeidae have less than 75% endemism, and aquatic oligochaetes have less than 40% endemic taxa in South America. Glossoscolecid species number 429 species in South America alone, a full two-thirds of the known megadrile earthworms. More than half of the South American taxa of Oligochaeta (424) occur in Brazil, being followed by Argentina (208 taxa), Ecuador (163 taxa), and Colombia (142 taxa). -

A phenogran based on the sane attributes conpares unfavourably with the phyLogralnsin establishing an acceptable classification., Hennigrs principle that sister-groups be given equal rank has not been followed for every group to avoid elevation of the more plesionorph, basal cLades to inacceptabl.y high ranks, the 0ligochaeta being retained as a Subclass of the class Clitellata. Three orders are recognized: the LumbricuLida and Tubificida, which were not conputed and the affinities of which require further investigation, and the Haplotaxida, computed. The Order Haplotaxida corresponds preciseLy with the Suborder Opisthopora of Michaelsen or the Sectio Diplotesticulata of Yanaguchi. Four suborders of the Haplotaxida are recognized, the Haplotaxina, Alluroidina, Monil.igastrina and Lunbricina. The Haplotaxina and Monili- gastrina retain each a single superfanily and fanily. The Alluroidina contains the superfamiJ.y All"uroidoidea with the fanilies Alluroididae and Syngenodrilidae. The Lurnbricina consists of five superfaniLies. -

This is an invertebrate animal that lives mostly in the upper layer of the soil. An earthworm is a segmented worm; a terrestrial invertebrate belonging to the phylum Annelida. They are the common inhabitants of moist soil and feed on organic matter. Earthworms are commonly called as farmer’s friend. This is because the worm casting (faecal deposit) increases the fertility and burrowing helps in proper aeration of the soil. Earthworms are commonly found in soil, eating a wide variety of organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. Generally, within a species, the number of segments found is consistent across specimens, and individuals are born with the number of segments they will have throughout their lives. The first body segment (segment number 1) features both the earthworm's mouth and, overhanging the mouth, a fleshy lobe called the prostomium, which seals the entrance when the worm is at rest, but is also used to feel and chemically sense the worm's surroundings. Some species of earthworm can even use the prehensile prostomium to grab and drag items such as grasses and leaves into their burrow.
