Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Technological alternatives for the control of Botrytis sp. In Andean blackberry (Rubus glaucus)

Enfoque UTE, 2020
The Andean blackberry crop (Rubus glaucus) is very important for the farmers, since they must implement cultural practices that allow reducing the use of synthetic pesticides. The objective of the study was to evaluate the effect of different technological alternatives for the control of Botrytis sp. in the blackberry crop.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

Insect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Incidence and Distribution of Viruses in Blackberry (Rubus sp.) in Alabama

International Journal of Fruit Science, 2010
A survey was conducted in 2007 to determine the incidence and distribution of viruses in commercial blackberry crops in Alabama. Symptomatic and asymptomatic plants in eight major blackberry producing counties were tested for Impatiens necrotic spot virus, Raspberry bushy dwarf virus, Tobacco ringspot virus, and Tomato ringspot virus using enzyme ...

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

Journal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),
