Adult female wasps of most species oviposit into their hosts' bodies or eggs. More rarely, parasitoid wasps may use plant seeds as hosts, such as Torymus druparum. [5] Some also inject a mix of secretory products that paralyse the host or protect the egg from the host's immune system; these include polydnaviruses, ovarian proteins, and venom ...
Another family, the Pompilidae, is a specialist parasitoid of spiders. [10] Some wasps are even parasitoids of parasitoids; the eggs of Euceros are laid beside lepidopteran larvae and the wasp larvae feed temporarily on their haemolymph, but if a parasitoid emerges from the host, the hyperparasites continue their life cycle inside the ...
The larvae are external parasitoids of their hosts, [4] and are not noticed due to their acquisition of the host’s odor. [13] After the wasps are fully developed, they emerge in large numbers. The males swarm around the nest in wait of the females. Mating takes place immediately, and oviposition occurs soon after. [10]
Copidosoma is a genus of chalcid wasps, which are parasitoids of Lepidoptera. [2] The wasps are polyembryonic , depositing one or two eggs into their host which then develop into multiple offspring and have a soldier caste and a reproductive caste.
Females often have long ovipositors, an organ that largely varies interspecifically. This variation is closely related to the host species upon which the wasp deposits its egg. Species that parasitize microlepidopterans, for instance, have longer ovipositors, presumably to reach the caterpillar through layers of plant tissue.
Ancistrocerus antilope female. Family Vespidae. Vespoidea is a superfamily of wasps in the order Hymenoptera. Vespoidea includes wasps with a large variety of lifestyles including eusocial, social, and solitary habits, predators, scavengers, parasitoids, and some herbivores.
Most parasitoid wasps dispatch prey in some such hideous manner, including entombing their paralyzed bodies. This tiny ichneumon wasp (Enicospilus purgatus) is nocturnal, as are most of its quarry ...
The most familiar members of the group are phytophagous, especially as gall-formers, though the actual majority of included species are parasitoids or hyperparasitoids. They are typically glossy, dark, smooth wasps with somewhat compressed bodies and somewhat reduced wing venation.
