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

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.

partellus fed on maize in which it occurs naturally, thus demonstrating the use of volatile chemical substances by the parasitoids to locate their hosts and their preference for their original host.
The study's architects suggest that the genomes could enhance pest control by providing information about which insects a parasitoid will attack, the dietary needs of parasitoids (to assist in economical, large-scale rearing of parasitoids) and identification of parasitoid venoms.
The decline in fruit damage is associated with lower leafroller density, which in turn is attributed to two key factors: (1) the introduction in the 1960s and subsequent spread of parasitoids attacking pupal and late larval stages of light brown apple moth and (2) the change in fruit production programs from frequent applications of broad-spectrum insecticides to less-intensive spraying with selective products.
The objective of this study was to determine seed wasps and parasitoids of gall was p, D.
The successful establishment but limited geographic spread of egg parasitoids in Florida spurred a search for new biological control agents, including two newly introduced wasp species: Fidiobia dominica from Dominica and Haeckeliania sperata from St.
Understanding how Strepsiptera parasitoids outwit host defenses is particularly exciting, she says, because the order's 500-plus species manage to prey on insects in 34 families.
These products could be ingested by parasitoids or penetrate the insect cuticle, resulting in toxicity (Malkones 2000).
Plastic containers were examined daily until the emergence of parasitoids, until the presence of mycosis, nematodes, or viral infections, or until FAW larvae reached adulthood.
Parasitoids may not be spatially connected to a host by the presence of the latter alone--they may be linked to only certain characteristics of the host's living environment (Laing 1937) because of the parasitoid's specific physical capabilities (Atkins 1980).
DURATION OF PLANT DAMAGE BY THE TOBACCO BUDWORM (HELIOTHIS VIRESCENS) AFFECTS THE ATTRACTION OF A SPECIALIST AND A GENERALIST PARASITOID TO COTTON ODORS.
Specific subgroups of parasitoids and the impact of climate change are also treated.
