Responses of Soil Arthropod Communities to Varying Shading Levels in Agriphotovoltaic Systems

open access: yesIntegrative Zoology, EarlyView.
Soil fauna was primarily influenced by crop type and season rather than AgriPhotovoltaic (APV) panels. Elevated panels increased soil temperature and soil organic matter in early wheat stages, while shading enhanced soil moisture for tomatoes, benefiting moisture‐sensitive taxa.

Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

open access: yesAgricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Spatial and seasonal patterns of potential orchard pollinators across a Lake Ontario gradient

open access: yesAgricultural and Forest Entomology, EarlyView.
Potential pollinator captures varied by season, trap height and distance from Lake Ontario, indicating that flower visitors were not evenly distributed during apple bloom. Several common bee genera, including Lasioglossum, Agapostemon, Andrena and Apis, overlapped more closely with apple bloom than the dominant retained fly genus, Toxomerus.

Sequence of Immunological Events During IgE‐Mediated Allergic Reactions to Food

open access: yesAllergy, EarlyView.
ABSTRACT Food allergies (FA) represent a significant global health burden. Upon allergen re‐exposure, allergic patients exhibit a sequence of symptoms that vary in terms of affected organ systems, severity, time of onset and allergen reactivity thresholds.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study

open access: yesAllergy, EarlyView.
Venom immunotherapy (VIT) during pregnancy, when maintenance dose is well tolerated, can be continued. No increased risk of adverse effects to VIT or safety concerns for the pregnancy or the newborns were observed. No decreased efficacy of VIT, in case of re‐stings, was reported.

Hymenoptera [PDF]

open access: yes, 2010
We present the first review of Hymenoptera alien to Europe. Our study revealed that nearly 300 species of Hymenoptera belonging to 30 families have been introduced to Europe. In terms of alien species diversity within invertebrate orders, this result ranks Hymenoptera third following Coleoptera and Hemiptera.
