“…Similarly significant reduction in total bacterial count in worms exposed to arsenic was observed in comparison to control when cultured on King'smedium B base, Burk's media, Yeast Mannitol Agar media and Nutrient agar media. Microbial population and humic acid content in earthworm casts represents a direct correlation with the increase in microbial population, there is an increase of microbial activity and humic acid content (Parthasarathi et al, 2007;Sonia et al, 2016). Being a part of soil fauna, worms are easily exposed to soil pollutants either due to ingestion or due to contact with skin (Dallinger and Rainbow, 1993).…”

The aim of the present study was to enumerate the diversity of gut bacterial population of epigeic earthworm species, E. eugeniae exposed to heavy metal. Adult earthworms were treated with three different doses (0.06%, 0.13% and 0.19% w/v) of potassium dichromate (K2Cr2O7) for this purpose. The gut samples were serially diluted and inoculated in seven distinct media viz. Jensen's media, King’smedium B base, Burk’s media, Yeast Mannitol Agar media, Vogel- Johnson agar base media, Luria Bertani Broth Miller and Nutrient agar media. Dose dependent decrease in bacterial population was observed in treated worms when compared with control. Maximum percent change (62.59%) in bacterial population was observed in Burk’s media when exposed to 0.19% chromium. The results revealed that chromium alters the microbial population present in gut of earthworms. Therefore, changes in earthworms’ gut microbial community due to soil management practices can also be used as markers of soil fertility and quality.

“…At the time of experiment termination, decreased growth parameters were observed. This might be because of the depletion of food (Bhat et al, 2016;Sonia et al, 2016). Weight loss in earthworms is also related to sexual maturity as the earthworm utilises maximum energy for reproduction purposes (Jesikha and Lekeshmanaswamy, 2013).…”

The present study evaluated the effect of autumn leaves as a food source on the growth and reproductive performance of Eisenia foetida. Three treatments, A, B, and C, each having five replicates, were designed in a total of 15 pots. For bedding soil, manure and autumn leaves were used in different ratios. The soil-to-leaf ratio in Treatment (A) was 3:1, the soil-to-manure-to-leaf ratio in Treatment (B) was 1:2:1, and the manure-to-leaf ratio in Treatment (C) was 3:1. Treatment C showed the most growth (Specific Growth Rate %, live weight gain, % gain in body weight and survivability) and was followed by Treatment B. All these parameters were recorded, with minimal in Treatment A, where soil and autumn leaves are mainly used in bedding. Also, high reproductive potential was recorded in treatments C and B as compared to A. Hence, the autumn leaves are good for the growth and reproduction of E. foetida provided the bedding has all the other nutritional requirements like manure and nutritive soil.

“…The greater potential of E. eugeniae for vermicomposting process has previously been reported (Coulibaly andBi et al, 2010 andSonia et al, 2016). Higher fecundity and growth rate of E. eugeniae in comparison with with Eisenia fetida (Maboeta et al, 1999) has brought about extensive use of it in commercial vermiculture (Sonia et al, 2016). Due to their wide distribution, night crawlers are the most broadly acknowledged test life form for ecotoxicological assessment particularly for soil environments.…”

The present study of 28 days was carried out to assess the effect of arsenic and chromium on biomass gain and reproduction parameters (cocoon and hatchling production) of E. eugeniae. The worms were cultured in substrate having different concentrations of arsenic and chromium alongwith control in triplicates. Dose and time dependent decreased in number of adults, cocoon production and hatchling emergence and reduction in growth was observed. In worms exposed to Cr (0.1 ppm), reduction in population (24.66%), body weight (2.44%), cocoon production (47.14%) and hatchling emergence (39.99%) was observed. While As (0.1 ppm) exposure resulted in reduction of adult population (10.66%), body weight (0.24%), cocoon production (37.05%) and hatchling emergence (28.53%) was observed. Cocoon production was observed to be the most sensitive parameter for heavy metal exposure in all treatments. Chromium was observed to be more detrimental to earthworms when compared with arsenic.
