Review ArticleOpen accessEvery word in the titleReview on Apiary Management and Antimicrobial Compounds as Alternative Prevention or Treatment for Honeybee DiseasesChanpen Chanchao, Marko Stoić, Mikio Yoshiyama, Kiyoshi KimuraHoneybees are important in terms of pollinators and bee products. However, honeybee colonies keep declining due to colony collapse disorder, loss of food sources, environmental deterioration, pesticide exposure and various diseases, as well as the interaction of these causes. Pathogenic infections are high because there is an antagonistic coevolution between host and pathogen/parasite, which leads to a reciprocal adaptation, as … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 15 Jan 2018 · 7,738 accessesView PDFCite
