Helicotylenchus Multicinctus
''Helicotylenchus multicinctus'' is a plant pathogenic nematode that affects primarily bananas and plantains. Nematodes of the genus ''Helicotylenchus'' are spiral nematodes and feed on a large variety of plant species. History and significance ''Helicotylenchus multicinctus'' was first described by Nathan A. Cobb in 1893 as ''Tylenchus multicinctus''. After further study by A.M. Golden in 1956 it was transferred to the genus ''Helicotylenchus''. As a plant parasitic nematode of bananas it is often considered second in importance to ''Radopholus similis''. Distribution Found in most banana and plantain growing regions of the world including tropical and temperate regions of Asia, Africa, North America, Central America, South America and the Pacific Islands.

Hoplolaimidae
Hoplolaimidae is a family of plant pathogenic nematodes. It has two subfamilies, Hoplolaiminae and Rotylenchulinae.

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Plant Pathogenic Nematodes
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...
