The genetic patterns of Middle Eastern A. mellifera subspecies have been understudied, hindering a comprehensive understanding of honey bee evolutionary history. Here, we studied the genetic integrity of five Middle Eastern subspecies across a broad geographical range: Turkey (A. m. anatoliaca, N=97; A. m. caucasia, N=75; A. m. syriaca, N=18), Jordan and Lebanon (A. m. syriaca, N=238 and N=29), Iran (A. m. meda...

Honey is highly susceptible to adulteration. Currently, the assessment of its geographical origin remains one of the most difficult tasks, which is typically performed by melyssopalynology. Recently, the attention has shifted towards indirect approaches such as the entomological origin based on geographical distribution patterns of honey bee subspecies. Although queens’ trade has impacted the natural subspecies...

This article presents managed honey bee colony loss rates over winter 2019/20 resulting from using the standardised COLOSS questionnaire in 37 countries. Six countries were from outside Europe, including, for the first time in this series of articles, New Zealand. The 30,491 beekeepers outside New Zealand reported 4.5% of colonies with unsolvable queen problems, 11.1% of colonies dead after winter and 2.6% lost...

This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 in Europe). In total, 28,629 beekeepers supplying valid loss data wintered 738,233 colonies, and reported 29,912 (4.1%, 95% confidence interval (CI) 4.0–4.1%) colonies with unsolvable queen problems, 79,146 (10.7%, 95% CI 10.5–10.9%) dead colonies after win...
