Impact assessment of genetically modified herbicide-tolerant cotton on arthropod communities

چکیده
Abstract Background Cotton ( Gossypium spp.) is one of the most important economic crops worldwide, and its production plays an role in economy many countries. Genetically modified herbicide-tolerant (GMHT) crops, which were developed to minimize losses caused by weeds, have gradually become widely adopted genetically world due their environmental benefits. However, potential ecological risks GMHT attracted extensive attention controversy. Arthropod communities form a prominent part biodiversity agroecosystems are indicators health. Elucidating effects on diversity arthropod necessary ensure safety crops. Result In this 2-year study, we investigated impact communities. The cotton variety GGK2 with glyphosate tolerance near-isogenic non-GMHT K312 used for experimental groups. Shannon index H ), Simpson D Pielou evenness J principal co-ordinates analysis (PCoA) Bray–Curtis distance evaluate population dynamics arthropods fields. No significant differences found between total abundance communities, indexes sampling dates. composition plots was similar. Sampling dates had effect indexes, whereas no clear tendencies related or × interaction recorded. addition, PCoA revealed high similarity K312. Conclusion There obvious difference abundance, under small-scale planting regime.

Changes in Arthropod Fauna From Weed Management Practices in Genetically Modified Herbicide-Tolerant Maize
Genetically modified maize tolerant to broad-spectrum herbicides may greatly alter weed flora composition, abundance and therefore affect organisms of higher trophic levels, including herbivore and detritivore arthropods and their natural enemies. This three-year study measured the effects on arthropods of an intensive use of broad-spectrum herbicides in comparison with one application of conve...

Anthropogenic chemical contamination is of concern due to the continuous decline of ecosys‐ tems.
