We employed an anti-Drosophila Orco antibody to detect Orco protein expression in antennae and sperm by immunofluorescence. Orco is expressed in the antennae, and localized in a cluster of cells that most most likely signify olfactory receptor neurons (ORN) (Fig. 3A)
The phylogenetic tree demonstrated in determine 1C is in concurrence with the results of present investigations into insect phylogenetic relationships .Orco expression in a cluster of cells in antennae indicates…
