Agricultural 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 ...

Agricultural 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 ...

, 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.

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

Agricultural and Forest Entomology, EarlyView.Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...

Agricultural and Forest Entomology, EarlyView.Twenty‐four bark beetle biocontrol programmes involving 41 natural enemy introductions are reported globally. A total of 36.6% of agents were established and 9.8% were reported effective, while many agent establishments and impacts often remained unassessed and incomparable across regions.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study
Allergy, 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.
