Discussion

  • E_Hb is assumed when cellular trophamnion disappears and teratocytes are released into host
  • Different f values may be needed to account for different food qualities of different host aphids
  • Mummy is treated like pupa in other insects
  • Weight of the mummy is entirely attributed to the wasp (weight of the cocoon shell is neglected)
  • Assimilation by imago is assumed to cover maintenance costs
  • No investment in reproduction buffer after emergence
  • As a consequence, the scaled reserve density remains constant at e_e
  • Parasitization over time was modeled using a linear phase followed by a decline phase

Facts

  • A. rhopalosiphi is a koinobiont; host aphids continue to move and grow for multiple days after parasitization (Ref: LannViss2012)
  • A. rhopalosiphi develops through three larval stages inside the host aphid (Ref: MuraLann2004)
  • Later, the aphid turns into an immobile mummy containing the nymphal parasitoid (Ref: LannViss2012)
  • After emergence, Aphidius parasitoids feed on sugar sources like nectar and honeydew (Ref: LuquPena2021)
  • The wasp imagos are not able to synthesize lipids (Ref: LannViss2012)
