Background Google Trends (GTs) is a web‐based surveillance tool that explores the searching trends of specific queries via Google. This tool proposes to reflect the real‐life epidemiology of allergic rhinitis and asthma. However, the validation of GTs against pollen concentrations is missing at the...
This article examines the biosecurity management of invasive species, focusing on the case of the control of ragweed ( Ambrosia artemisiifolia), an invasive plant with allergen pollen. An ethnographic survey was conducted in France’s Rhône-Alpes region among local residents’ communities, farmers, an...
Biological control using natural antagonists has been a most successful management tool against alien invasive plants that threaten biodiversity. The selection of candidate agents remains a critical step in a biocontrol program before more elaborate and time-consuming experiments are conducted. Here...
One of the key input parameters for numerical pollen forecasts is the distribution of pollen sources. Generally, three different methodologies exist to assemble such distribution maps: (1) plant inventories, (2) land use data in combination with annual pollen counts, and (3) ecological modeling. We...
OBJECTIVE: The prevalence of ragweed allergy is increasing worldwide. Ragweed distribution and abundance is spreading in Europe in a wide area ranging from the Rhone valley in France to Hungary and Ukraine, where the rate of the prevalence can peak at as high as 12%. Low-grade ragweed colonisation w...
