par·a·si·toid

(par'ă-sī'toyd),
Denoting a feeding relationship intermediate between predation and parasitism, in which the parasitoid eventually destroys its host; refers especially to parasitic wasps (order Hymenoptera) the larvae of which feed on and finally destroy a grub or other arthropod host stung by the mother wasp before laying its egg(s) on the host.

par′a·sit·oid′ adj.

parasitoid

any of the alternately parasitic and free-living wasps and flies, such as the ichneumon fly, whose larvae parasitize and often kill members of the host species.

The developmental strategy of an idiobiont ectoparasitoid, Dendrocerus carpenteri: influence of variations in host quality on offspring growth and fitness.
This selection occurs because, in insect parasitoids, the fitness of the offspring is affected by the host chosen by the female, particularly in idiobiont ectoparasitoids.
annuus, showed that idiobiont ectoparasitoids were represented by two species of Diglyphus, D.
pulchripes, and a decrease in differences in larval mortality between novel and normal plants [ILLUSTRATION FOR FIGURE 4 OMITTED] could be due to the generalist nature of Diglyphus, a solitary idiobiont ectoparasitoid.
Herbivore mortality rates thus increase through host development, but this increase comprises both delayed mortality from koinobionts that attacked hosts earlier in their life cycle as well as immediate mortality by later attacks from both predators and idiobiont parasitoids that require fully grown larvae and pupae for development.
The increased risk of parasitism for leaf miners is particularly evident in the late-larval stage, when the bulk of idiobiont attacks occur and when many early-attacking koinobionts finally kill their hosts.
Under these conditions, it was expected that the idiobiont ectoparasitoid, D.

The genus Uscana Girault (Hymenoptera: Trichogrammatidae) is comprised of solitary and idiobiont endoparasitoids, with 90% of its species using eggs of the coleopteran subfamily, Bruchinae, as hosts.
