Expression of the melittin gene of Apis cerana cerana (Hymenoptera: Apidae) in insect cells

open access: yesEuropean Journal of Entomology, 2006
A fragment encoding melittin cDNA from Apis cerana cerana fused with glutathione S-transferase gene was inserted into the multiple cloning site of the pBacFastHTb to construct a recombinant donor plasmid, pBacHT-GSTAccM, which was transposed to the ...

Pattern of population structuring between Belgian and Estonian bumblebees [PDF]

open access: yes, 2019
Several population genetic studies investigated the extent of gene flow and population connectivity in bumblebees. In general, no restriction in gene flow is considered for mainland populations of common bumblebee species.

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees

open access: yesJournal of Pollination Ecology, 2023
Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Identification and abiotic stress response of a glutamine synthetase gene (AccGS) from the Asiatic honeybee, Apis cerana cerana (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2014
Glutamine synthetase (GS) is an essential detoxification enzyme that plays an important role in stress responses; however, little information regarding the function of this enzyme in hymenopteran insects is available.

Expression of heat-shock protein genes in Apis mellifera meda (Hymenoptera: Apidae) after exposure to monoterpenoids and infestation by Varroa destructor mites (Acari: Varroidae)

open access: yesEuropean Journal of Entomology, 2017
Heat shock proteins (hsps) protect proteins in eukaryotic cells from damage. Expression of hsps in insects subject to different environmental stimuli is poorly characterized.

Late Winter Foraging by Honeybees (Hymenoptera: Apidae) at Sapsucker Drill Holes [PDF]

open access: yes, 2017
Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did
