  • V. canescens is a koinobiont parasitoid wasp, i.e. allows its host to continue development after parasitism. (ref: HarvHarv1994)
  • It has hydrophic eggs, meaning that they take up nutrients in the embryo-stage. (ref: HarvHarv1994)
  • This species does not host-feed, so host access is just for oviposition. (ref: HarvHarv1994)
  • This entry is discussed in LlanMarq2015 (ref: LlanMarq2015)


  • Hydrophic egg is modelled as a new maturity level E_Hx, which preceeds birth
  • E_Hx is treated as birth, while at E_Hb uptake switches from absorbtion to feeding
  • All parasitoid data is from host (moth Plodia interpunctella) that was infected at instar 5
  • Assimilation by imago is assumed to cover maintenance costs
