Abstract This study explores the food plant spectrum of sugar beet weevil ( Asproparthenis punctiventris Germar; Coleoptera: Curculionidae), one most important pests Beta vulgaris subsp. Altissima group). It examines potential various weeds and other plants to maintain populations A. adults larvae outside fields. To this end, leaf consumption females males on twelve Amaranthaceae six Polygonace...

The uptake of arsenic by plants from contaminated soils presents a health hazard that may affect home gardeners neighboring contaminated environments. A controlled greenhouse study was conducted in parallel with a co-created citizen science program (home garden experiment) to characterize the uptake of arsenic by common homegrown vegetables near the Iron King Mine and Humboldt Smelter Superfund...

the importance of amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including iran with a high positive rate (69%) among iranian allergic patients. the aim of the present study is to identify the allergenic properties of a. retroflexus pollen. sixteen patients with allergy to a. retroflexus pollen were selected for the study. the antigenic ...

The three plants presented in this study are Amaranthus spinosus, Amaranthus caudatus and Amaranthus viridis L. They belong to the Amaranthaceae family and are traditionally used as vermicides. Our aim was to investigate the anthelmintic activity of the three plants using earthworms (Pheretima posthuma). Methanol extracts of the three plants at different concentrations (10, 20, 40, 60, 80, 100 ...

Paraguay, a country whose economy is based mainly on agriculture and livestock for export, has experienced a major expansion in mechanized crops during the last few decades. Despite being heavily dependent on agriculture, Paraguay has very limited research on crop weeds, in spite of these having a high economic impact on production. This work aims to update and enhance the knowledgebase on the ...

UNLABELLED • PREMISE OF THE STUDY The evolution of invasiveness has been extensively studied in natural ecosystems; however, far less is known about the evolution of agricultural invasiveness, despite the major economic impact of weeds on crop productivity. Examining the population structure of recently arisen weeds can provide insights into evolutionary avenues to invasion of agroecosystems....
