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.
[parasite + G. eidos, appearance]

parasitoid

(păr′ə-sĭ-toid′, -sī′toid)
n.
An organism, usually an insect, that lives on or in a host organism during some period of its development and eventually kills its 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.

In the same way, in another study, it was reported that the host quality or size is commonly correlated to the parasitoid fitness, especially in idiobiont parasitoids, whose offspring may depend on the quality and size of the host at the time of oviposition (Gols and Harvey, 2008; Fortuna et al., 2012).
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.
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.
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.
Yet, the koinobiont endoparasitoid Pseudapanteles dignus (Muesebeck, 1938) (Hymenoptera: Braconidae) and the idiobiont ectoparasitoid Dineulophus phthorimaeae (De Santis, 1983) (Hymenoptera: Eulophidae) accomplish over 50% of natural parasitism and exhibit promising attributes for either augmentative or conservation biological control in the native range of T.
(2008) and de Leon & Setamou (2010) reviewed the history and effectiveness of the host specific idiobiont ectoparasitoid Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) in controlling 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.
