Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps being in the wasp-waisted Apocrita. As parasitoids , they lay their eggs on or in the bodies of other arthropods , sooner or later causing the death of these hosts .
Parasitoids are found in a variety of taxa across the insect superorder Endopterygota, whose complete metamorphosis may have pre-adapted them for a split lifestyle, with parasitoid larvae and free-living adults. Most are in the Hymenoptera, where the ichneumons and many other parasitoid wasps are highly
In other species, the eggs are laid directly into plant tissues and form galls, which protect the developing larvae from predators, but not necessarily from other parasitic wasps. In some species, the larvae are predatory themselves; the wasp eggs are deposited in clusters of eggs laid by other insects, and these are then consumed by the ...
Parasitoids hold other insect populations in balance, and in turn provide food for scores of other predators. Many parasitoid wasps are important pollinators, too.
The Pteromalidae are a large family of wasps, the majority being parasitoids of other insects. They are found throughout the world in virtually all habitats, and many are important as biological control agents. The oldest known fossil is known from the Early Cretaceous. [1]
Parasitoids are insects which sooner or later kill their hosts, placing their relationship close to predation. [32] Most parasitoids are parasitoid wasps or other hymenopterans; others include dipterans such as phorid flies. They can be divided into two groups, idiobionts and koinobionts, differing in their treatment of their hosts. [33]
Several wasps feed on Queen’s Anne lace plants on June 29, 2012, in Davis, California. ... adding that they are “good to have around” to eat other bugs such as caterpillars.
They stand erect on the plant on which they hatched, and without any distinguishable preparation, jump about 10 mm from the leaf onto a foraging ant. [8] 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.
