  9. Solitary Eumenidae

  10. Subsocial vs. Solitary Wasp • Subsocail Wasp • Begins provisioning just before egg hatching • Continues until the larva grows to instars 3-5, for about one week. • Solitary Wasp • Lays an egg and then provisions for 1-2 days • After sealing with a mud wall, starts the second oviposition

  11. Subsocial vs. Solitary Wasp Subsocial - 줄무늬감탕벌 Solitary -황슭감탕벌 • Emerge from mid to late Jun • Oviposition begins ca. 4 days • after emergence until late Aug • 2nd generation emerge in Aug, • oviposit until mid Oct • 4. Prepupaediapause in cells • Females: 1st (2-2.5 months) • 2nd (1-1.5 months) • 6. One female lays 6-8 eggs • Emerge from Jun to Jul • 2. Mate soon after emergency • 3. Oviposit from mid Aug to late Oct • 4. Prepupaediapause in cells • 5. Females: 2-3 months • 6. One female lays 20-30 eggs

  13. Vespoidea • Masaridae • Feed on plants • Feed their offspring with nectar and pollen • Vespidae– Venom studies • The true vespid wasps kill their prey • Feed their offspring with flesh of the killed prey • Eumenidae • Long-term, non-lethal paralysis Venom of Wasp

  14. Components of Venom Honey Bee Peptides and Amines - Mellittin - Apamin - MCD-Peptide - Histamin - Dopamin - Serotonin - Norepinphrin Enzymes- Phospholipase A- Hyaluronidase - Acidic phosphatase - 58 enzymes Hornet, Yellow jacket and Wasp • Mellittin-like peptides • Bombolitin: Bumblebee venom • (17 amino acid amphiphilic alpha-helix) • Mastoparan: Wasp venom • (14 amino acid amphiphilic alpha-helix) • crabrolin: Hornet venom (13 amino acid amphiphilic alpha-helix) • Antigen 5

  15. Clinical Effects of Venom http://www.insectstings.co.uk/

  16. Mellitin의 작용기작 Mellitin is the chief toxin with a helical structure by virtue of which it can form pores within cell membranes causing structural disruption. Toxin dispersion is facilitated by hyaluronidase which is known to increase capillary permeability. Corneal avascularity results in a high concentration of toxins with delayed washout

  17. Active Amines • Serotonin, Histamine, Tyramine and Catecholamine • Major pain-producing principles • Polyamines (putrescine, spermidine and spermine) • - spider and scorpion venom • Kinins(혈관 확장, 평활근의 수축 또는 저혈압 등을 일으키는 내외성 펩티드) • Pain-producing wasp peptides • Bradykinin-like peptides (snake) • Release histamine from mast cells • Mastoparan • Mast cell degranulating peptides • Granule- and Histamine-releasing peptides • Allergens • Acid phosphatas, Hyaluronidase and Phospholipase • Nonenzymatic protein (Antigens 5) – The most active allergen Venom of Vespid

  20. Kaltenpoth et al., 2005. Current Biology, 15, pp. 475-479 Secretion of White Substance by a Beewolf Female in the Brood Cell After entering the brood cell, the beewolf female moves its body laterally and secretes massive amounts of white substance from its specialized antennal glands. The particles are smeared to the ceiling of the cell. The whole process takes about 30 s. Uptake of White Substance by a Beewolf Larva in the Brood CellThe larva is apparently searching for the white substance and ingests parts of it.
