To identify the venom components and their expression patterns of some Aculeata bees/wasps, venom gland-specific transcriptome analysis was conducted. FPKM values were normalized with the average of the transcription level of reference gene (a-tubulin). Common components in both solitary and social wasp venoms include hyaluronidase, phospholipase A2, metalloendopeptidase, etc. Although it has been expected that more diverse bioactive components with the functions of prey inactivation and physiology manipulation are present in solitary wasps, the information on venom compositions of solitary wasps obtained in this study was not sufficient to generalizae this notion. Nevertheless, some neurotoxic peptides (e.g., pompilidotoxin and dendrotoxin-like peptide) and proteins (e.g., insuline-like peptide binding protein) appear to be specific to solitary wasp venom. In contrast, several proteins, such as venom allergen 5 protein, venom acid phosphatase, and various phospholipases, appear to be relatively more abundant in social wasp venom. In the venom gland trancsriptome of bumblebees, major allergens or pain producing factors were barely identified, implying that bumblebee venoms are relatively less toxic than those of social or solitary wasps.
