Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Ants contribute to raspberry pollination in protected cropping systems

Agricultural 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 ...

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

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 ...

Introgression of lineage c honey bees into black honey bee populations: a genome-wide estimation using single nucleotide polymorphisms (SNPS) [PDF]

, 2012
The black honey bee, Apis mellifera mellifera L., is probably the honey bee subspecies more threatened by introgression from foreign subspecies, specially lineage C A. m. carnica and A. m. ligustica.

Effects of exposure of honey bee colonies to neonicotinoid seed–treated maize crops

Journal of Apicultural Science, 2013
The effects to honeybee colonies (Apis mellifera L.) during and after exposure to flowering maize (Zea mays L.), grown from seeds coated with clothianidin and imidacloprid was assessed in field-realistic conditions.

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.

Using honey in wound care [PDF]

, 2006
Honey is primarily a herbal product with some modifications that are made by the bees that process the nectar or sap collected from the plants to store as honey. The types of phytochemicals present in a honey depend on the plant source of the honey.

Frequency and Severity of Allergic Reactions to Non‐Mandatory Labelled Allergenic Foods—Data From Two Large European Cohorts

Allergy, EarlyView.
In two large European cohorts, 589 reactions to non‐mandatory labelled plant‐based foods were identified with sunflower seed, pine nut, pea and lentil as the most frequent triggers. Reaction severity was not different between mandatory and non‐mandatory labelled allergenic foods. Their frequency and rising trends (e.g., fenugreek, pumpkin seed) support
