A survey of the genus Ceratina Latreille (Hymenoptera: Apidae) in northern Iran, with three new records [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2016
A field survey of the bee fauna was conducted in the north of Iran during 2009 to 2015. Special concern was given to the tribe Ceratinini (Hymenoptera; Apidae). Ten species of the genus Ceratina were collected and identified in the present study.

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

open access: yes, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Pollination of Sedirea japonica (Orchidaceae) by Bombus diversus diversus (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2013
There are no records of the pollinators of many orchids even though the Orchidaceae are often cited as the example of an intimate relationship between plants and their pollinators.

Taxonomic note on the type species of Centris (Melanocentris) (Hymenoptera: Apidae) [PDF]

open access: yes, 2018
Centris (Melanocentris) Friese is one of many subgenera that have been proposed throughout the taxonomic history of the bee genus Centris Fabricius.  The lack of critical study of the type specimens of its type species, Centris atra Friese, resulted in ...

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

Pollen types collected by Tetragonisca angustula (Hymenoptera: Apidae) in dry vegetation in Northeastern Brazil

open access: yesEuropean Journal of Entomology, 2014
Knowing the floral origin of the pollen collected by native bees in Neotropical ecosystems enables us to understand the dynamics of the interdependent relationships between the insects and the native flora.

Macronutrient composition in pollen affects development and survival in wild bees

open access: yesPhysiological Entomology, EarlyView.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

The draft genome sequence of the Japanese honey bee, Apis cerana japonica (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2018
Honey bees are not only important for honey production but also as pollinators of wild and cultivated plants. The Eastern honeybee (Apis cerana) is more resistant to several pathogens than the Western honeybee (Apis mellifera), and the genomes of two ...

Insects Associated with Michigan Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

open access: yes, 2017
(excerpt) Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees,
