What is Synovigenic?
Synovigenic: Those species (most parasitoids) of hymenoptera which continue to produce eggs throughout the adult stage. Production of eggs is dependent on the nutrition of the adult female rather than on the metabolites retained from the immature stages.
What is parasitoid in biology?
parasitoid, an insect whose larvae feed and develop within or on the bodies of other arthropods. Each parasitoid larva develops on a single individual and eventually kills that host.
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.
How would you explain indirect Hyperparasitism?
Indirect Hyperparasitism is that type of hyperparasitism in which a parasitoid attacks a host insect upon which it itself is incapable of developing with the purpose of encountering the primary parasitoid which the secondary host may contain.
What is Hyperparasite give example?
A hyperparasite 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 super parasite?
Definition of superparasitism : parasitization of a host by more than one parasitic individual usually of one kind —used especially of parasitic insects.
What is the difference between parasite and parasitoid?
A parasite is an organism that lives in or on another species (its host) and benefits by deriving nutrients at the other’s expense, resulting in the death of the host. A parasitoid is an insect whose larvae live as parasites that eventually kill their hosts (typically other insects).
What is a parasitoid give 3 examples?
Parasitoids include species of wasps, flies (e.g. tachinid flies), beetles and worms (e.g. gordian worms).
Can parasites lay eggs in humans?
Strongyloidiasis. Another type of tiny roundworm (Strongyloides stercoralis) causes this disease. People mainly get them when young worms in soil go through their skin. Once in the body, the worms find their way to the small intestine and lay eggs.
Are viruses parasites?
Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host.
What is a hyperparasite?
Definition of hyperparasite : a parasite that is parasitic upon another parasite.
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 the meaning of syngeneic?
Definition of syngeneic : involving, derived from, or being genetically identical or similar individuals of the same species especially with respect to antigenic interaction syngeneic tumor cells grafts between syngeneic mice — compare allogeneic First Known Use of syngeneic 1961, in the meaning defined above
What is synovitis?
What is synovitis? What is synovitis? Synovitis (or synovial inflammation) is when the synovium of a joint becomes inflamed (swollen). The synovium, which is also sometimes called the stratum synoviale or synovial stratum, is connective tissue that lines the inside of the joint capsule.
What is the function of the synovium?
This membrane produces a special fluid to lubricate the joint and prevent wear on cartilage while the joint is in motion. Injuries, osteoarthritis and various types of inflammatory arthritis can cause swelling of the synovium, which can lead to pain and other symptoms. What is synovitis? What is synovitis?
What causes fluid in the synovium?
This membrane produces a special fluid to lubricate the joint and prevent wear on cartilage while the joint is in motion. Injuries, osteoarthritis and various types of inflammatory arthritis can cause swelling of the synovium, which can lead to pain and other symptoms.
