^aOBP names from Gotzek et al. (Gotzek et al. 2011).

^bQuantification from exponentially multiplied protein abundance index (emPAI), calculated from mass spectrometry data (Ishihama et al. 2005) and normalized to the emPAI values of glyceraldehyde 3-phosphate dehydrogenase (GAPDH).

^cAlso known as Gp-9.

^dGenes located on social chromosome (Pracana et al. 2017).

^eOnly one peptide detected.
