The life cycle of a typical trematode begins with an egg. Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like ...
The length of the life cycle is temperature-dependent. [ 16 ] [ 17 ] The relationship between rate of development and temperature is linear over much of the root-knot nematode life cycle, though it is possible the component stages of the life cycle, e.g. egg development, host root invasion or growth, have slightly different optima.
Myrmeconema neotropicum's life cycle begins when a bird eats the infected ant. Upon passing through the bird's digestive system the eggs are defecated out. The eggs are then picked up by the ants and fed to their larvae. Once inside the immature ant gut the eggs migrate to the gaster where they will fully mature.
Females acquire a globose shaped body while males become vermiform and leave the roots. Upon maturity females lay eggs into a gelatinous mass that protect them against unfavorable environmental conditions, and the life cycle is repeated. It takes 37 days at 21 °C (70 °F) for M. incognita to complete its life cycle. [7] [10] [11]
Contracaecum is a genus of parasitic nematodes from the family Anisakidae. These nematodes are parasites of warm-blooded, fish eating animals, i.e. mammals and birds, as sexually mature adults. The eggs and the successive stages of their larvae use invertebrates and increasing size classes of fishes as intermediate hosts.
The microfilaria (plural microfilariae, sometimes abbreviated mf) is an early stage in the life cycle of certain parasitic nematodes in the family Onchocercidae. [1] In these species, the adults live in a tissue or the circulatory system of vertebrates (the "definitive hosts"). They release microfilariae into the bloodstream of the vertebrate host.
The life cycle is 17 to 29 days long. [6] The juvenile molts once while still inside the egg. [11] The eggs hatch in 8 to 10 days. The juvenile molts three times to reach the immature stage. [11] The immature female parasitizes the root for one to two weeks. [4] During this time the male deposits sperm, which the female stores until her gonads ...
The life cycle of the female citrus nematode is 6–8 weeks long, whereas the male citrus nematode only lives for about 7–10 days. These nematodes reproduce by amphimixis and parthenogenesis. The first-stage juvenile (J1) undergo one molt while still in the egg.
