Efficacy of Steinernema feltiae Nematode Against Lesser Mealworm (Alphitobius diaperinus) Populations from Poultry Farms in Türkiye

摘要

In poultry farms, a beetle called the lesser mealworm (Alphitobius diaperinus) is a common pest that causes significant problems. This beetle not only damages the structures where poultry are kept but also spreads harmful bacteria, such as Salmonella and Escherichia, which can cause diseases in poultry and pose risks to food safety. Traditionally, chemical insecticides have been used to control these pests, but they can leave harmful residues in poultry products and lead to pesticide resistance. Our study tested a natural method using a type of beneficial nematode, Steinernema feltiae, which is a microscopic worm that can kill the beetles without harming the poultry or leaving chemical residues. We found that these nematodes were particularly effective against beetle larvae. The results suggest that S. feltiae could be a valuable tool in reducing the need for chemical insecticides, making poultry farming safer and more sustainable. This natural approach can help protect animal health, reduce environmental impacts, and ensure safer food products for consumers.
