Steinernema Riobravis
Steinernema is a genus of nematodes in the family of Steinernematidae. The genus ''Steinernema'' is named after the nematologist Gotthold Steiner. Life cycle Species form Symbiosis, symbiotic relationships with ''Xenorhabdus'' and ''Photorhabdus'' bacteria. The free-living third stage juvenile, termed a dauer juvenile, enters its insect hosts through natural openings, such as the mouth, anus, and Spiracle (arthropods), spiracles. Bacterial cells from the intestines are regurgitated into the insect. The insect hemolymph provides a rich medium for the bacterial cells which grow, releasing toxins and exoenzymes, causing the insect host to die from septicemia. The bacteria also produce other compounds to protect the insect from other microbes in the soil. The nematode moves out of its developmentally arrested third, nonfeeding stage, triggered by either bacterial or insect food signals. The nematodes feed on the bacteria and moult to the fourth stage, reaching adulthood within a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Steinernema Carpocapsae
''Steinernema carpocapsae'' is an entomopathogenic nematode and a member of the family Steinernematidae. It is a parasitic roundworm that has evolved an insect-killing symbiosis with bacteria, and kills its hosts within a few days of infection. This parasite releases its bacterial symbiont along with a variety of proteins into the host after infection, and together the bacteria and nematode overcome host immunity and kill the host quickly. As a consequence, ''S. carpocapsae'' has been widely adapted for use as a biological control agent in agriculture and pest control. ''S. carpocapsae'' is considered a generalist parasite and has been effectively used to control a variety of insects including: Webworms, cutworms, armyworms, girdlers, some weevils, and wood-borers. This species is an example of an "ambush" forager, standing on its tail in an upright position near the soil surface and attaching to passing hosts, even capable of jumping. As an ambush forager, ''S. carpocapsae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
