The study of nematode biology has led to a dramatic increase in understanding of how all animals function. In fact, the bacterial-feeding nematode, Caenorhabditis elegans, is one of the best-understood animals on earth. The fate of every cell in C. elegans development has been carefully mapped. It was the first animal to have its DNA sequence completely deciphered, and it is amenable to detailed genetic analysis. The study of C. elegans has led to new insights into the details of animal development, neurobiology, behavior, and has been of great value in biomedical research as well as in the understanding of nematode biology
The reason nematodes are so useful for biological research is due to their simple anatomy and transparent bodies. Nematodes are simple animals, often only containing 1000 cells or less. Nematodes in all or part of their life cycle are worm-shaped (vermiform), although some species become swollen and rounded in later life stages. The basic body plan of a nematode is a tube within a tube. They have an outer skin or cuticle that is secreted from an inner hypodermis.
The muscles are attached longitudinally to the nematode’s hypodermis, allowing them to move only in the dorsal ventral direction (snake-like movement). Inside the nematode there is an inner tube, the alimentary canal, which runs inside the nematode from head to tail. Between the alimentary canal and the body wall is fluid that provides pressure against the wall to maintain body shape and allow movement. At the head of a plant-parasitic nematode is a hollow mouth spear (like a hypodermic needle) called a stylet.
The nematode uses this stylet to puncture plant cells, to withdraw food and also to secrete protein and metabolites that aid the nematode in parasitizing the plant. The stylet is connected to the pharynx that, in turn, is connected to the intestine. The intestine ends at the rectum in the female nematode and the cloaca in the male. Attached to the pharynx are three - five salivary glands which produce secretions that may be emitted from the stylet and that assist the nematode in plant invasion and parasitism.
NEMATODES AND TREATMENTS
It is difficult to treat nematodes in soil.
But it is not impossible.
For preventing plant roots from nematodes, controlling and getting rid nematodes. You can prepare own special organic liquid mixture for killing nematodes yourself, both economically and so effective.
preparation of this special organic liquid mixture, You need some ingredients that you can find your country easily, formulation and production process. You need no help and no technıcal support to make this mixture. simple mixing is sufficient.
Below textbook has a formulation and manufacturing process of special organic liquid mixture and methods of application to treat nematodes. You can produce special organic liquid mixture for getting rid nematodes easily and apply to soil safety.
