Abstract

Helicotylenchus species, a type of spiral nematode are among the most destructive biotic stressors in the world's major agricultural growing regions. Cereals and horticulture crops are vulnerable to these plant parasite nematodes. It parasitizes a variety of host plants and has a considerable harm potential at relatively low population density. It is difficult to identify the signs of the harm that plant parasitic nematodes have caused. Their minuscule size further lessens the likelihood that they will be identified as the creatures causing any harm. While some nematodes function as different vectors, others predispose plants to other infections. With the exception of Antarctica, they are more widely dispersed over all continents with temperate and tropical temperatures. These plant parasites are thought to be responsible for crop yield losses of more than US$ 300 billion globally. According to estimates, these losses would amount to over 14% in developing nations and over 9% in rich nations. Compared to temperate locations, tropical regions experience far more damage from nematodes. This plant-parasitic nematode has a short life cycle, which is backed by several academics in literatures. In the right circumstances, the life cycle is said to be finished in about 32 days. The species is bisexual by nature and reproduces by amphimixis or cross-fertilization. The goal of integrated nematode management is to bring nematodes down to manageable numbers using a range of strategies, such as genetically resistant hosts, predators and parasites, naturally occurring environmental changes. Therefore, economic importace, theclassification, life cycle, damage symptoms, and management of the helicotylenchus nematode will be covered in this review paper, along with an updates on the relationship between helicotylenchus species and many important agricultural crops worldwide, especially in Ethiopia.
