Bacterial responses to environmental herbicide pollutants (glyphosate and paraquat)
The toxic effect of herbicides on non- target microorganisms may influence degradation of organic matter resulting in changes to nutrient cycling. In the present study, different strains of bacteria incubated in media containing different concentrations of glyphosate and paraquat were assessed over a period of two incubation terms. The deleterious impact of the herbicide was observed as glyphos...
متن کاملAntibiotics cause parthenogenetic Trichogramma (Hymenoptera/Trichogrammatidae) to revert to sex.
Completely parthenogenetic Trichogramma wasps can be rendered permanently bisexual by treatment with three different antibiotics or high temperatures. The evidence strongly suggests that maternally inherited microorganisms cause parthenogenesis in these wasps. Theories predict female-biased sex ratio in offspring under the influence of maternally inherited symbionts, but extreme sex ratios of 1...
متن کاملToxicity determination of three sturgeon species exposed to glyphosate
Glyphosate, N–(phosphonomethyl) glycine, has been widely used to control agricultural weeds in the north of Iran. However, it is also supposed to have adverse effects on natural sturgeon population. The present study was undertaken to evaluate the acute toxicity of glyphosate to three different sturgeon species (Huso huso, Acipenser stellatus, and A. persicus) under laboratory conditions. Fis...
متن کاملA revision of the Indian species of Oligosita Walker (Hymenoptera: Trichogrammatidae).
The Indian species of the genus Oligosita Walker, 1851 (Hymenoptera: Trichogrammatidae) are revised. One new species, Oligosita aseta Begum & Anis, sp. nov., is described based on specimens collected from Kerala, India. A key to the 16 Indian species of the genus is also given.
متن کاملGlyphosate and herbicide resistant plants
There is a common understanding that commercially traded formulations of glyphosate, such as Roundup, can be more toxic than glyphosate alone. Therefore, the EU has already taken measures to remove problematic additives known as POE tallowamine from the market. However, imports of genetically engineered plants resistant to glyphosate are exposed to high dosages of the herbicide in countries whe...
