Potential effects of oilseed rape expressing oryzacystatin-1 (OC-1) and of purified insecticidal proteins on larvae of the solitary bee Osmia bicornis [PDF]

open access: yes, 2008
Despite their importance as pollinators in crops and wild plants, solitary bees have not previously been included in non-target testing of insect-resistant transgenic crop plants.

Pollination in a fire‐prone world: Reduced solar radiation and warming alter plant–pollinator interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change can disrupt ecosystem services such as pollination. Warming increases the frequency and scale of wildfires, leading to smoke‐induced reductions in incident solar radiation, which together may affect plants, pollinators and their interactions. To determine

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

open access: yesInsect Science, EarlyView.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

Parasitism of \u3ci\u3eAncistrocerus Antilope\u3c/i\u3e (Hymenoptera: Eumenidae) by Leucospis Affinis (Hymenoptera: Leucospididae) [PDF]

open access: yes, 2017
The chalcid wasp Leucospis affinis has been known to parasitize only megachilid bees. Its rare occurrence as a parasite of the eumenid wasp Ancistrocerus antilope indicates that eumenid wasps may be a large resource this chalcid is not ...

Floral strips increase the abundance and spillover of beneficial insects in rotational crop fields

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract Insects provide many ecological functions that support agricultural production, but beneficial insect populations are often lower in areas of intensive agriculture. Agronomic practices that support beneficial insect populations are important for sustainable crop production.

Associations between soil characteristics and ground‐nesting bees on farms Associations entre les caractéristiques du sol et les abeilles terricoles dans les exploitations agricoles

open access: yesInsect Conservation and Diversity, EarlyView.
We collected ground‐nesting bees at 35 farms over two summers and assessed their abundance, diversity, and community composition in relation to local soil characteristics (texture, compaction, slope, and ground cover). Ground‐nesting bee abundance and species richness increased with bare ground and sand content.

Analysis of the Diversity of Megachilidae Bees on the Northern Subplateau of the Iberian Peninsula [PDF]

open access: yesJournal of Insect Science, 2010
In the western Mediterranean, 772 species of bees in the family Megachilidae have been reported. Special emphasis has been placed on the Iberian Peninsula, where to date 218 species are known. However, few intensive studies providing information about communities of Megachilidae have been carried out. Two earlier works cite 70 species; almost one third
