Importance and role

Importance of genus to ecosystem

Species of Nematostoma are parasitic and can attack living hosts, penetrate the outer defenses, invade them, and obtain nutrition from living cytoplasm, thereby causing disease and sometimes death of the host (Clark 2018).


Industrial relevance and applications

The industrial applications of Nematostoma has not been investigated.


Quarantine significance

The biocontrol properties of Nematostoma has not been studied.


Biochemical importance of the genus, chemical diversity or applications

The chemical application of Nematostoma has not been studied. Nematostoma may produce important enzymes and toxins. Fresh cultures are needed for further studies.


Diversity of the genus

Nematostoma comprises 17 species known several host plants such as Asteraceae, Campanulaceae, Dilleniaceae, Fabaceae, Lamiaceae, Malpighiaceae, Pinaceae, Primulaceae, Solanaceae, Verbenaceae. two species N. guianense and N. lantanae have been synonymized and transferred to another genera Hyalomeliolina and Nematostigma respectively. Nematostoma is reported from Australia, Brazil, China, Costa Rica, Ecuador, Florida, India, Japan, Malaysia, Missouri, Poland, Rhode Island.
