Ardahan yöresindeki gezginci ve sabit arıcılara uygulanan anket sonuçlarının değerlendirildiği araştırmada, arıcılık işletmelerinin sonbahar bakım ve kontrolleri, kışlatma ve hastalıklarla ilgili özellikleri incelenmiştir. Yöredeki arıcıların %90.60'ının sonbahar yemlemesi yaptığı, sonbahar beslemesinde çoğunlukla şeker şurubunu %57.75 kullandıkları ve bal şurubu ile besleme yapmanın pek yaygın olmadığı anlaşılmaktadır. Anket sonuçları Ardahan yöresindeki arıcıların sonbahar dönemindeki ana arı kontrolü ile varroa mücadelesi konularında duyarlı olduklarını göstermektedir. Yörede gezginci arıcıların büyük bir çoğunluğu (%67.65) kışlatma kayıplarının %10 ve daha az olduğunu bildirirken, sabit arıcılar %54.95 oranında kışlatma kayıplarının %10-19 arasında olduğunu belirmişlerdir.

“…Despite the growing public awareness of pollinators' importance, the beginning of the 21 st century has been marked by compelling evidence of the decline in pollinators and dependent plants (Burkle et al, 2013;Morse & Calderone, 2000;Potts et al, 2010;Vanbergen & Initiative, 2013). Honey bees are the most researched pollinators; the decline in honey bee populations and deterioration of their health has been linked to a number of causes, including pesticide exposure (S anchez-Bayo et al, 2016;Wood et al, 2018), climate (Beyer et al, 2018), infectious and parasitic diseases (Grozinger & Flenniken, 2019;Higes et al, 2008;Mart ın-Hern andez et al, 2011), agricultural intensification (Ricketts et al, 2008;Winfree et al, 2009), and loss of genetic diversity (Forfert et al, 2017). Rigorous field and laboratory protocols have been established to study declines in honey bees.…”

The accelerating decline of pollinator populations has become increasingly concerning in the last two decades. Honey bees are economically important pollinators and a model species to evaluate pollinator health. The decline in queen quality is one of the frequently reported causes associated with honey bee losses worldwide. Histopathology is an essential tool used for diagnostics and research in mammalian species and may provide insight into the histomorphological basis of a decline in queen quality. Thus, the purpose of this study was to summarize the previously described normal morphology of the entire reproductive tract of mated honey bee queens and to illustrate it by high quality photomicrographs. Accordingly, reproductive tracts of one-year old mated honey bee queens were processed for histology, serially sectioned, stained with hematoxylin and eosin, and used for the capture of high quality histological photomicrographs of the entire reproductive tract. This study illustrates the microscopic morphology of the queen reproductive tract which may facilitate further investigations of the cause and pathogenesis of the recent decline in reproductive fitness of honey bees using histopathology.

“…Many reports concluded that biotic and abiotic factors are suspected to be involved in this phenomenon, either alone or in combination . Potential causes are exposure to i) environmental and in‐hive chemicals, ii) agricultural practices, iii) infection by micro‐organisms and predation by parasites, and iv) nutritional factors, among others, which lead to the transition from a health status qualified as normal to a health decline that would contribute to the colony collapse . The expression of this pathological state may notably be linked to a decrease in the immune capacities of the bee and/or the colony .…”

MALDI–MS Profiling to Address Honey Bee Health Status under Bacterial Challenge through Computational Modeling

Honey bees play a critical role in the maintenance of plant biodiversity and sustainability of food webs. In the past few decades, bees have been subjected to biotic and abiotic threats causing various colony disorders. Therefore, monitoring solutions to help beekeepers to improve bee health are necessary. Matrix‐assisted laser desorption ionization–mass spectrometry (MALDI–MS) profiling has emerged within this decade as a powerful tool to identify in routine micro‐organisms and is currently used in real‐time clinical diagnosis. MALDI BeeTyping is developed to monitor significant hemolymph molecular changes in honey bees upon infection with a series of entomopathogenic Gram‐positive and ‐negative bacteria. A Serratia marcescens strain isolated from one naturally infected honey bee collected from the field is also considered. A series of hemolymph molecular mass fingerprints is individually recorded and to the authors' knowledge, the first computational model harboring a predictive score of 97.92% and made of nine molecular signatures that discriminate and classify the honey bees’ systemic response to the bacteria is built. Hence, the model is challenged by classifying a training set of hemolymphs and an overall recognition of 91.93% is obtained. Through this work, a novel, time and cost saving high‐throughput strategy that addresses honey bee health on an individual scale is introduced.
