What do you call a parasite that kills its host?
Parasitoids are small insects whose immature stages develop either within or attached to the outside of other insects, referred to as hosts. Parasitoids eventually kill the host they feed on, as opposed to parasites like fleas and ticks, which typically feed upon hosts without killing them.
What is Hyperparasite give example?
A hyperparasite, also known as a metaparasite is a parasite whose host, often an insect, is also a parasite, often specifically a parasitoid. Hyperparasites are found mainly among the wasp-waisted Apocrita within the Hymenoptera, and in two other insect orders, the Diptera (true flies) and Coleoptera (beetles).
What is an example of a parasitoid?
Parasitoids include species of wasps, flies (e.g. tachinid flies), beetles and worms (e.g. gordian worms).
What is parasitoid in biology?

What is an intermediate host in microbiology?

What is meant by Hyperparasitism?
Hyperparasitism—the parasitic habit of one species upon another parasitic species—has also attracted attention. Polyembryony, the development of many individuals (as many as 1,000) from a single egg, is an unusual phenomenon occurring in some members of the families Chalcididae and Proctotrupidae.
What is predator and parasitoid?
Predators capture and eat other organisms such as insects or mites. Predators include ladybird beetles, ground beetles, lacewings, syrphid (hover) flies, aphid midges (Aphidoletes) and yellowjacket wasps. Parasitoids are insects that parasitize other insects.
