The infective larval stage of Ascaris lumbricoides, a type of roundworm, is the third-stage larva (L3). This larva develops within the eggs after they are laid and must undergo a process of maturation in the environment, usually in soil, to become infective. Once ingested by a host, the eggs hatch in the intestines, releasing the larvae that can then migrate through the body.
The infective stage of Taenia saginata, also known as the beef tapeworm, is the larval form called the cysticercus. This stage is typically found in the muscle tissue of cattle, the intermediate host. When humans ingest raw or undercooked beef containing cysticerci, they can become infected with T. saginata.
CATERPILLAR
No, reptiles do not have a larval stage. Unlike some amphibians and insects, reptiles hatch from eggs in a form that resembles miniature adults. They do not undergo metamorphosis like amphibians that have larval stages such as tadpoles.
Larva
planula
Yes they do.
no
Sporozoite is the infective stage of Maaria.
No, platyhelminthes do not have a trochophore larval stage. Trochophore larvae are typically characteristic of marine annelids and mollusks. Platyhelminthes have a diverse range of reproductive strategies, but they do not generally exhibit a trochophore larval stage in their life cycle.
Infective stage is the life cycle stage where parasite able to initiate an infection in a definitive or intermediate host. Diagnostic stage is the life cycle stage leaving the definitive host, it is the stage that links the parasitic way of life with either the free-living phase of the life cycle or the phase of development that occurs in an intermediate host.
