Parasitoid

Image:Collinia sp.jpg Parasitoids differ from parasitesin their relationship with the host. In a truly parasitic relationship, the parasite and host live side by side with little or no damage to the hostorganismwhile the parasite takes enough nutrients to live on and reproduce without draining the host's reserves in full. In a parasitoid relationship, the host is usually killed after the full development of the other organism. This type of relationship seems to occur only in organisms that have fast reproduction rates (such as insectsor mites).

There are three groups of insect that are particularly renowned for this type of lifestyle. The largest and best known group comprises the division Apocrita: Parasitica of the order Hymenoptera(including the chalcidwasps (family Chalcidae) and the ichneumon wasp(family Ichneumonidae). The other two are the tachinidflies (order Diptera, family Tachinidae) and the stylopidflies (order Strepsiptera, family Stylopidae).
