Abstract

This study investigated the impact of volatile oils from onion flower nectar on honey bee colony health over two consecutive seasons (2023-2024). Six colonies were divided into a treatment group (pollinating onion flowers) and a control group. Colonies were monitored monthly for worker bee mortality and for diseases, including chalkbrood, stonebrood, Nosema, Varroa, and American foulbrood. Results demonstrated that the treatment groups exhibited a significant decline in bee mortality and a 61-74% reduction in chalkbrood incidence, while stonebrood was completely absent. Furthermore, treated colonies showed a complete clearance of Nosema, Varroa, and American foulbrood within weeks, maintaining a pathogen-free status. In stark contrast, control colonies experienced a significant increase in all disease parameters and mortality. Statistical analysis confirmed a 73% reduction in Nosema, a 79% reduction in Varroa, and a 58% reduction in mortality in onion-pollinated colonies, with all comparisons highly significant (p < 0.001). The study concludes that onion flower volatile oils possess strong bioactive properties, offering a potent, sustainable alternative to chemical treatments for enhancing bee health and suppressing disease.

Özet

Bu çalışma, iki ardışık mevsimde (2023-2024) soğan çiçeği nektarından elde edilen uçucu yağların bal arısı kolonilerinin sağlığı üzerindeki etkisini araştırmıştır. Altı koloni, bir tedavi grubu (soğan çiçeklerini tozlaştıran) ve bir kontrol grubu olarak ikiye ayrılmıştır. Koloniler, işçi arıların ölüm oranı ve kireçli yavru hastalığı, taş yavru hastalığı, Nosema, Varroa ve Amerikan yavru hastalığı gibi hastalıklar açısından aylık olarak izlenmiştir. Sonuçlar, tedavi gruplarında arı ölüm oranlarında önemli bir düşüş ve kireçli yavru hastalığı vakalarında %61-74 oranında bir azalma olduğunu gösterirken, taşlı yavru hastalığı vakaları tamamen ortadan kalkmıştır. Ayrıca, tedavi edilen kolonilerde birkaç hafta içinde Nosema, Varroa ve Amerikan yavru hastalığı tamamen ortadan kalkmış ve koloniler patojen içermeyen durumlarını korumuştur. Buna karşın, kontrol kolonilerinde tüm hastalık parametrelerinde ve ölüm oranlarında önemli bir artış gözlemlenmiştir. İstatistiksel analiz, soğanla tozlaşan kolonilerde Nosema'da %73, Varroa'da %79 azalma ve ölüm oranında %58 düşüş olduğunu doğrulamış ve tüm karşılaştırmaların son derece anlamlı olduğu ortaya çıkmıştır (p < 0,001). Çalışma, soğan çiçeği uçucu yağlarının güçlü biyoaktif özelliklere sahip olduğu ve arı sağlığını iyileştirmek ve hastalıkları önlemek için kimyasal tedavilere güçlü ve sürdürülebilir bir alternatif sunduğu sonucuna varılmıştır.
