Effect of malathion on the male reproductive organs of earthworms, Eisenia foetida.
AIM To observe the cytotoxic effect of the organophosphate insecticide malathion in the reproductive tissues of the earthworms, Eisenia foetida. METHODS Worms were nourished in soil treated with malathion at single sub-lethal doses of 0, 80, 150, 300 and 600 mg/kg soil. (LD50=880 mg/kg soil) and evaluated on days 1, 5, 15 and 30 after exposure. The body weights were recorded and male reproduc...
متن کاملEarthworms newly from Mongolia (Oligochaeta, Lumbricidae, Eisenia)
Two new megadrile earthworms from the steppes, the first species wholly from Outer Mongolia, are ascribed to the partially parthenogenetic Eisenia nordenskioldi (Eisen, 1879) species-complex. Taxonomic justification of sympatric Eisenia nordenskioldi mongol and Eisenia nordenskioldi onon ssp. n. are supported by mtDNA COI barcodes. The unreliability of molecular differentiation based on voucher...
متن کاملPotential of earthworm (Eisenia foetida) as dietary protein source for rohu (Labeo rohita) advanced fry
Earthworm, a non-conventional protein source with 520–530 g protein kg−1 on dry matter basis was used in three forms viz. (i) whole earthworm (ii) earthworm custard, and (iii) pelleted earthworm diet to prepare three iso-nitrogenous (500 g protein kg−1 diet) and iso-caloric (17.0 MJ kg−1 diet) experimental diets. The formulated diets were fed ad libitum twice daily to Labeo rohita advanced fry ...
متن کاملToxic effects of PCDD/Fs mixtures on Eisenia andrei earthworms.
The earthworms Eisenia andrei were used to study the toxicity of PCDD/Fs mixtures to earthworms during 28 day of exposure. The experiments were performed on artificial soils contaminated with dioxins at levels of C1 (0.1 ng 2, 3, 7, 8-TCDD/g soil), C2 (1 ng 2, 3, 7, 8-TCDD/g soil) and C3 (1.5 ng 2, 3, 7, 8-TCDD/g soil). Effects of PCDD/Fs on survival, growth rate and immune responses; phagocyto...
متن کاملIsolation and Characterization of Cellulase Producing Streptomyces albaduncus from Gut of Eisenia foetida
Cellulose is the most abundant biopolymer on earth, recognized as the major component of plant biomass. The cellulolytic microorganisms were isolated from gut of earthworm (Eisenia foetida). Using Glycerol asparagine agar media, the organisms were identified as Actinomycetes sps.. The endoglucanase activity of the culture broth was determined during actinomycetes growth by measuring the release...
