Rotylenchus cypriensis

Rotylenchus cypriensis is a species of plant-parasitic nematode belonging to the order Tylenchida and the family Hoplolaimidae. As a soil-borne pest, it significantly impacts agricultural productivity by feeding on the root systems of various plant species, leading to severe nutrient deficiency and plant stress.

The host range of Rotylenchus cypriensis is diverse, affecting numerous horticultural, woody, and herbaceous crops. It is particularly problematic in greenhouses and intensive farming systems, where the nematode can persist for long periods in soil and spread rapidly through contaminated irrigation sources and agricultural tools.

The biology of this nematode involves a life cycle characterized by larval stages that undergo molting to reach maturity. As a semi-endoparasite, it uses its specialized feeding apparatus, known as a stylet, to pierce the root cells of the host. This process not only deprives the plant of essential nutrients but also creates entry points for various soil-borne pathogens.

Damage symptoms often appear as stunted growth, yellowing foliage, and chlorosis. Because the roots are directly attacked, the plants exhibit a reduced root mass and limited capacity to uptake water, which becomes especially critical during periods of drought or high heat. Heavy infestations lead to significant economic losses due to reduced quality and yield.

Effective management strategies for controlling Rotylenchus cypriensis include:

• implementing strict phytosanitary measures for soil and plant material;
• crop rotation with non-host plant varieties;
• steam sterilization or chemical fumigation in enclosed growing areas;
• application of nematicides or biological control agents (such as beneficial bacteria or fungi);
• enhancing soil health through the addition of organic matter to support natural antagonists.
