Sex- and Male-Morph-Specific Variation in Brain Mass and Cell Number Scaling in Solitary Centris pallida (Hymenoptera: Apidae) Bees. [PDF]
We counted the number of cells in bees’ brains. Female C. pallida bees have more neurons in their brains overall than males. Small male morph bees had fewer cells and reduced densities in the visual input brain regions than large morph males, despite specializing on sight to find mates.

An overlooked family-group name among bees: Availability of Coelioxoidini (Hymenoptera: Apidae) [PDF]
Recent phylogenetic analysis of the family Apidae has applied the tribal name Coelioxoidini to the distinctive genus Coelioxoides Cresson, which has been thought to be related to Tetrapedia Klug. However, the nomenclatural status of such a family ...

Origin of Jordanian honeybees Apis mellifera (Hymenoptera: Apidae) using amplified mitochondrial DNA
The honeybee (Apis mellifera L.) has a large number of geographic subspecies distributed across Europe, Africa and Asia, many of which have been described. This identification is important for bee breeding and preserving honeybee biodiversity.

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