Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Plant parasites are a common term for sap-sucking insects like aphids. [19]
Plant-eating insects such as scale insects, aphids, and caterpillars closely resemble ectoparasites, attacking much larger plants; they serve as vectors of bacteria, fungi and viruses which cause plant diseases. As female scale insects cannot move, they are obligate parasites, permanently attached to their hosts.

A parasitic disease, also known as parasitosis, is an infectious disease caused by parasites. [1] Parasites are organisms which derive sustenance from its host while causing it harm. [ 2 ] The study of parasites and parasitic diseases is known as parasitology . [ 3 ]
This kind of host switching has been shown many times: in insect–plant relationships where oligophagy in locusts manifests itself on distantly related plants, [25] plant–disperser relationships among Mediterranean birds, [26] plant–pollinator relationships between hummingbirds and Heliconia flowers, [5] and for parasite–host ...
