Ancylostoma duodenale

It is essential for agronomists to clarify that Ancylostoma duodenale (the old world hookworm) is a parasitic nematode belonging to the order Strongylida and the family Ancylostomatidae. This organism is not a plant pest. It does not feed on any agricultural crops, nor does it affect plant physiological processes or agricultural production yields. Its biological existence is strictly tied to mammalian hosts.

The biology of this parasite revolves around its developmental stages in the soil. Under favorable conditions, such as high moisture and warm temperatures in organic-rich substrates, the larvae can survive in the top layer of soil. While these conditions are often found in greenhouse environments or field soils, they pose no threat to the crops growing there, as the parasite does not interact with the plant anatomy.

There is no economic damage caused by Ancylostoma duodenale to cultivated plants. It does not cause root rot, leaf necrosis, or any form of phytopathology. The confusion often arises from the general classification of "soil-borne nematodes," as many plant-parasitic nematodes (like Meloidogyne species) are major pests; however, Ancylostoma is strictly a biological risk to humans, not a danger to the crop itself.

The primary concern for the agricultural sector regarding this parasite is occupational health and safety. Farm workers are at risk of infection if they work in contaminated soil without protective equipment. The larvae can penetrate the skin, leading to parasitic infestation, which impacts labor efficiency and necessitates medical intervention for the staff involved in soil preparation and greenhouse management.

To ensure safety on the farm, management must implement strict hygiene and protective protocols:

• Mandatory use of personal protective equipment, such as sturdy boots and protective gloves, during soil work.
• Implementation of comprehensive personal hygiene standards for all workers after contact with the soil.
• Regular cleaning and sanitization of worker facilities, including showers and breakrooms.
• Proper management of organic fertilizers to ensure they do not become breeding grounds for parasitic larvae.
