Sex- and Male-Morph-Specific Variation in Brain Mass and Cell Number Scaling in Solitary Centris pallida (Hymenoptera: Apidae) Bees. [PDF]

open access: yesJ Comp Neurol
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.

A serine protease from the midgut of the bumblebee, Bombus ignitus (Hymenoptera: Apidae): cDNA cloning, gene structure, expression and enzyme activity

open access: yesEuropean Journal of Entomology, 2007
A serine protease gene was cloned from the bumblebee, Bombus ignitus. The B. ignitus serine protease (BiSP) gene spans 1702 bp and consists of four introns and five exons coding for 250 amino acid residues. Southern blot analysis of genomic DNA suggested

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 ...
