Key definitions with regard to parasitoid physiology and host-parasitoid network structure
Term
Definition
Example species (family)
Eclosure
The act of an adult parasitoid emerging from its pupa.
n/a
Ectoparasitoid
The larvae of the parasitoid feeds upon the host externally.
Nasonia vitripennis (Pteromalidae)
Egg parasitoid
A specific type of parasitoid that attacks the eggs of its hosts.
Dicopomorpha echmepterygis (Mymaridae)
Electivity
The degree to which a consumer shows preference in which
resources it consumes.
n/a
Endoparasitoid
The larvae of the parasitoid feed upon the host from inside of it.
Aphidius evri (Braconidae)
Host-plant
Plant on which the hosts of the primary parasitoids can be found.
n/a
Hyperparasitoid
Any parasitoid species that feeds upon other parasitoids.
Alloxyistini: hyperparasitoids of aphids
(Figitidae, Charipinae)
Idiobiont
Parasitoid species life-history trait in which the host development
is arrested by the act of oviposition.
'Tarantula hawk' (Pepsis spp.; Pompilidae)
Koinobiont
Parasitoid species life-history trait in which the host continues
development after a successful oviposition event.
Aphidius evri (Braconidae)
Mummy
A cocoon formed by the parasitoid larva within the dried
exoskeleton in which it pupates.
n/a
Mummy parasitoid
Specific type of hyperparasitoid that attacks its hosts during the
mummy stage.
Asaphes vulgaris (idiobiont hyperparasitoid
of aphids) (Pteromalidae)
Oviposition
The act in which females parasitoids lay their eggs.
n/a
Primary parasitoid A trophic level in host-parasitoid networks; describes a parasitoid
that attacks non-parasitoid hosts (such as aphids).
Aphidinae: parasitoids of aphids
(Braconidae)
Pro-ovigeny
A parasitoid life-history trait where the parasitoid ecloses with its
entire egg complement in a mature state; can be an adjective,
that is, more pro-ovigenic. Exists on a spectrum with the other
end being represented by a synovigenic life history.
Copidosoma floridanum (Pteromalidae) a
pro-ovigenic parasitoid wasp
Synovigeny
A parasitoid life-history trait where the parasitoid matures its eggs
of the course of its adult lifetime; see pro-ovigeny.
Gelis agilis (Ichneumonidae), a synovigenic
parasitoid wasp
