A comparative study of invasive Helianthus annuus populations in their natural habitats of Argentina and Spain [PDF]

, 2010
Wild Helianthus annuus is native to North America but it naturalized in other parts of the world as well. Although the origin of exotic populations is uncertain, they have probably evolved very differently in different countries. To unravel the origin of

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

AutoPollS: A tool for automated monitoring of pollinators using deep learning

Methods in Ecology and Evolution, EarlyView.
Abstract Deep learning and computer vision hold enormous potential for automated monitoring of biodiversity, including pollinators and other insects. Efficient, scalable monitoring of insect pollinators is crucial given pollinators' role in supporting biodiversity and agricultural productivity amidst declining pollinator populations.

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

Allergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Persistência e fitotoxicidade do herbicida atrazine aplicado na cultura do milho sobre a cultura do girassol em sucessão Persistence and phytotoxicity of the herbicide atrazine applied on corn crop on successive sunflower crop

Planta Daninha, 2002
Embora o herbicida atrazine aplicado na cultura do milho seja seletivo para esta cultura, pode causar fitotoxicidade em cultivos em sucessão/rotação. Dois experimentos foram conduzidos em campo, a fim de avaliar o efeito residual do herbicida atrazine ...

Sunflower (Helianthus annuus) Seed Allergy

Journal of Investigational Allergy and Clinical Immunology
Background: Sunflower seed is one of the most common edible seeds. Its consumption is growing. Cases of sunflower seed allergy have been reported since the 1970s. However, there are few data on the prevalence and clinical manifestations of sunflower seed allergy. Objective: To improve our understanding of sunflower seed allergy.
