Common ragweed ( Ambrosia artemisiifolia L.) is an annual Asteraceae species native to North America which is highly invasive across Europe and has harmful impacts, especially on human health and agriculture. Besides its wide ecological range, particularly its high reproductive power by seeds is promoting its spread to various habitats and regions....
Chapter
Various types of demographic data can be collected in the field: population censuses, capture–mark–recapture data, and so on. These data sources share common demographic information about the studied population. Bayesian integrated population models (IPM) make efficient use of these different types of demographic data by jointly analysing them. Thi...

Invasive alien species (IAS) can substantially affect ecosystem services and human well-being. However, quantitative assessments of their impact on human health are rare and the benefits of implementing IAS management likely to be underestimated. Here we report the effects of the allergenic plant Ambrosia artemisiifolia on public health in Europe a...
Article
Full-text available
One of the biggest challenges in classical biological control of invasive weeds is predicting the likelihood of success. Ambrosia artemisiifolia, a North American plant species that has become invasive in Europe, causes economic losses due to health problems resulting from its huge amount of highly allergenic pollen and as a weed to agricultural cr...

Full-text available
Augmentative biological control by predaceous ladybird beetles can be improved by using flightless morphs, which have longer residence times on the host plants. The two-spot ladybird beetle, Adalia bipunctata (L.) (Coleoptera: Coccinellidae), is used for the biological control of aphids in greenhouses and on urban trees. Flightlessness due to trunc...
Article
Maps of cropping practice, including the level of weed infestation, are useful planning tools e.g. for the assessment of the environmental impact of the crops, and Northern Italy is an important example due to the large and diverse agricultural production and the high weed infestation. Sentinel-2A is a new satellite with a high spatial and temporal...
Article
Full-text available
Both weed science and plant invasion science deal with noxious plants. Yet, they have historically developed as two distinct research areas in Europe, with different target species, approaches and management aims, as well as with diverging institutions and researchers involved. We argue that the strengths of these two disciplines can be highly comp...
Article
Full-text available
Roadsides are an important habitat for invasive common ragweed, Ambrosiaartemisiifolia L., by facilitating seed dispersal. Reducing the size of roadside populations is therefore essential for confining this highly allergenic species. Here, we aim to determine the cost-effectiveness of mowing regimes varying in frequency and timing, by analysing pop...
Article
Full-text available
To better manage invasive populations, it is vital to understand the environmental drivers underlying spatial variation in demographic performance of invasive individuals and populations. The invasive common ragweed, Ambrosia artemisiifolia, has severe adverse effects on agriculture and human health, due to its vast production of seeds and allergen...
Article
Full-text available
Experimentally applying pesticides is an important method to assess the efficacy of weed biocontrol agents, but potential direct effects of the chemicals on plant performance are controversial or unknown. We assessed how three broad-spectrum insecticides applied in combination affect the performance of the widely invasive, crop-yield reducing, alle...

Several recent studies undertaken by members of COST SMARTER have examined temporal and spatial variations in airborne Ambrosia pollen at different scales, which can be u...
Article
Full-text available
The North American invasive alien Ambrosia artemisiifolia L. (common or short ragweed) is considered to be an important weed in agriculture and source of highly allergenic pollen (Smith et al. 2013; Essl et al. 2015 references therein) in many parts of the world, including Europe. The oligophagous leaf beetle Ophraella communa LeSage 1986 (Coleopte...
Article
Full-text available
This study aims to determine whether a significant decrease in airborne concentrations of Ambrosia pollen witnessed in the north-west of the Province of Milan in Northern Italy could be explained by environmental factors such as meteorology, or whether there is evidence to support the hypothesis that the decrease was related to the presence of larg...
Conference Paper
The continued spread of common ragweed, Ambrosia artemisiifolia¸ in Europe is a growing problem. Whereas the pollen cause severe health problems, the plant is an agricultural weed, and seed production forms the source for population growth and dispersal. In 2013, large populations of the ragweed leaf beetle, Ophraella communa (Coleoptera: Chrysomel...

Bladluizen in stadsbomen zorgen soms voor grote overlast. Vooral onder lindebomen is er jaarlijks wel een periode van honingdauwoverlast. Sommige steden gaan het probleem te lijf met het uitzetten van tweestippelige lieveheersbeestjes in de lindebomen. Het resultaat is niet altijd bevredigend. Nu is het effect van deze maatregel voor het eerst onde...
Thesis
The central theme of this PhD thesis is natural variation in the wing length of the predatory two-spot ladybird beetle, Adalia bipunctata. ‘Wingless’ individuals of this species occur occasionally. They possess truncated wing covers and flight wings and cannot fly, but the extent of the reduction is highly variable between individuals. At one hand,...

Full-text available
We report a case of genetic linkage between the two major loci underlying different wing traits in the two-spot ladybird beetle, Adalia bipunctata (L.) (Coleoptera: Coccinellidae): melanism and winglessness. The loci are estimated to be 38.8 cM apart on one of the nine autosomes. This linkage is likely to facilitate the unravelling of the genetics...

Kernrot is het (gedeeltelijk) wegrotten van de spruit binnenin de tulpenbol. Deze schade is aan de buitenkant van de bol niet zichtbaar, waardoor ogenschijnlijk gezonde bollen na planten geen of een misvormde bloem geven. Het is nooit opgehelderd welke mijten precies kernrot veroorzaken: bollenmijten (waarmee in dit geval mijten van het geslacht Rh...

The challenge of using ladybird beetles for biological control of insect pests such as aphids is that the adult beetles tend to fly away from the host plants. Therefore, flightless ladybirds might improve biocontrol. There are several artificial ways to obtain flightless beetles, but it may be preferable to use natural variation in flight ability....
