It has an iridescent blue-violet sheen on its skin that is visible in bright light.

life cycle; Perionyx excavates; Vermiculture. Fungal colonies (CFU x 10 4/g soil ) in control (no amendment) soil on 0 day with Perionyx excavatus as test species Fig-3.2. The clitellum, or "collar," of the mature P. excavatus begins approximately 12 segments from its mouth and covers segments …

AbstractThe life cycle of Perionyx excavatus has been studied and the potential of this epigeic earthworm spe-cies for breaking down and processing organic wastes is well known. The rates of growth and reproduction of P. excavatus, on a variety of … Perionyx excavatus Fig-2.2. The moisture requirements of P. excavatus were studied in cattle manure (particle size 500–1000 μm) at 25°C by exposing the worms to different, but constant moisture levels. Set up earthworm (Perionyx excavatus) farms and develop products from earthworm and wormwood fertilizers for organic agriculture Composting organic fertilizer with agricultural products Collecting, isolating and growing medicinal and edible mushrooms Cultivating Cordyceps militaris developing products from Cordyceps militaris Experimental process of growing organic turmeric with … Identification of potent biomolecules through anticancer studies may facilitate their usage in drug … In order to exploit the concept of using vermiculture as biotechnology for waste control and protein production, the life cycle of the vermicomposting species, Perionyx excavatus, was studied.

Eisenia foetida. Understanding of its optimal environmen-tal requirements is required in order to optimize and accelerate the vermicomposting process. The moisture preferences of both juvenile and clitellate specimens were determined at 25°C in undivided moisture towers filled … Life cycle of Tasar silkworm (Antheraea mylitta) Fig-2.1.

The aim of the present study is to evaluate the cytotoxic effect of ECF of Eudrilus eugeniae (EE), Eisenia foetida (EF), and Perionyx excavatus (PE) on oral cancer cell line SCC-9. The growth and …

Fig-2.3. Description: Perionyx excavatus is a small earthworm, averaging 1.2 to 2.7 inches in length, with a deep purple anterior and dark red or brown posterior.

These worms are highly active and twitch when disturbed. From the results obtained it can be deduced that although P. excavatus survives and grows at a moisture level of 59.9% (25), the lowest moisture level at which it would be able to complete its life cycle successfully at 25, is 65%. The results showed that the worms grew and reproduced best between moisture levels of 75.2 and 83.2%. Moisture … The development, growth and reproduction of P. excavatus were investigated. Experimental pots of vermicomposting . Earthworm as one of the best means of abating organic pollution and also to minimize indiscriminate use of inorganic fertilizers.

Observations on the biology of Drawida nepalensis, Metaphire houlletiand Perionyx excavatuswere made, which were reared in cow manure and oak litter under laboratory conditions over a period of 150 days. Fig-3.1. Fungal colonies (CFU x 104/g soil) in control (no amendment) soil after 60 days … At these lower moisture levels, however, the worms were very inactive and covered by substrate particles which adhered to the mucus layer covering their bodies.

Earthworms have important functions by virtue of their feeding and general behavioral activities like burrowing, digesting, excreting with microorganisms and supporting further decomposition of biodegradable matters.

The present study also attempts to investigate the cell cycle analysis and mechanism of cell death induced by ECF on SCC-9 cell line. Life cycle of Eri silkworm (Philosamia ricini) Fig- 1.3.
