a = Total number of larva ESTs (n = 286501); b = Total number of pupa ESTs (n = 162608); c = Total number of worker1 ESTs (n = 318664); d = Total number of worker2 ESTs (n = 194969); e = Total number of male ESTs (n = 257318); f = Total number of gyne ESTs (n = 221683); g = Total number of ESTs (n = 1441743).
Potential odorant-binding proteins and chemosensory proteins in the BT_transcriptome_v2 contigs are shown, with read counts for each of the life cycle stages. The highest amount of ESTs per contig are highlighted in bold.
