Ophraella communa LeSage (Coleoptera: Chrysomelidae), native to North America (LeSage 1986), was discovered first in China in 2001 on the invasive weed, Ambrosia artemisiifolia

It does look very similar to ragweed, Ambrosia artemisiifolia
, an American native which has made its way over here and is notable for its wind-blown pollen which is highly allergenic.
Here, we quantify the potential consequences of climate change on pollen allergy, focusing upon the annual herbaceous plant common ragweed (Ambrosia artemisiifolia
) in Europe (henceforth referred to as ragweed).
A study of invasive Ambrosia artemisiifolia
under different light availability also demonstrated that RGR remained unchanged at 100, 50 and 30% irradiance (QIN et al., 2012).
Ragweed (Ambrosia artemisiifolia
) is native to North America but since the 1960s has spread rapidly across warmer parts of Europe.
Kochia (Kochia scoparia), Canada fleabane (Conyza canadensis), and both common and giant ragweed (Ambrosia artemisiifolia
and Ambrosia trifida, respectively) are four resistant species resident in Canada; and of these, kochia and Canada fleabane are present in the Okanagan.
Ragwitek contains an extract from short ragweed (Ambrosia artemisiifolia
Serum-specific IgE was measured for the following allergens: Japanese cedar (Cryptomeria japonica), Japanese cypress (Chamaecyparis obtusa), grass (Dactylis glomerata, Phleum pratense, and Ambrosia artemisiifolia
), cat dandruff, dog dandruff, molds (Alternaria alternata, Aspergillus, and Candida), and mites (Dermatophagoides pteronyssinus and Dermatophagoidesfarinae).
Global healthcare company Merck (NYSE:MRK) (MSD outside the US and Canada) announced on Wednesday the acceptance for review by the US Food and Drug Administration (FDA) of its Biologics License Application (BLA) for its investigational ragweed pollen (Ambrosia artemisiifolia
) sublingual allergy immunotherapy tablet.
Tests conducted by an international team of researchers, led by physician-scientists at Johns Hopkins, showed that treatment with the pill, which contains the protein Ambrosia artemisiifolia
major allergen 1, and is placed under the tongue to be absorbed, also reduced the need for anti-allergy drugs.
In the Midwestern region, one finds that annual and biennial species (e.g., Ambrosia artemisiifolia
, Setaria spp.
