The trypanosome Lotmaria passim and the microsporidian Nosema ceranae are common parasites of the honey bee, Apis mellifera, intestine, but the nature of interactions between them is unknown. Here, we took advantage of naturally occurring infections and quantified infection loads of individual workers (N = 408) originating from three apiaries (four colonies per apiary) using PCR to test for int...

The aim of the study was to the development of the method for the separation, identification and determination quantitatively of the major constituents of honeybee (Apis mellifera L.) venom by high performance liquid chromatography (HLPC) and determination of the chemical composition of the domestic product by running routine tests. In the study to develop an HPLC method to assay the major veno...

background: the varroa destructor varroasis is a very serious parasite of honeybee apis mellifera . the objective of this study was to evaluate the effectiveness of varroa treatment using organic acid (oxalic acid) in algeria identify­ing its side effects on bee colonies. methods : treatment was conducted in one apiary consisting 30 colonies kept in langstroth hives kind. oxalic acid dripped di...

the microsporidium nosema apis is a protozoan parasite specific for the epithelial cells of the ventricles of adult bees. nosemosis occurs throughout the world. between february and may 2002-2003, samples were randomly collected twice from 20 apiaries in urmia region north-west of iran. during this survey total of 487 hives were examined for infection with n. apis. in the first stage of study (...

INTRODUCTION Honeybees are constantly exposed to a wide range of vital and non-vital pressures that may interact with each other and affect the health or survival of the insects. Pesticides are the main danger for the insects, and they subsequently have impacts on human and environmental health. METHODS Field research was conducted in the apiary of Hada Al Sham Research Station, where the wor...

Identifying plant taxa that honey bees (Apis mellifera) forage upon is of great apicultural interest, but traditional methods are labor intensive and may lack resolution. Here we evaluate a high-throughput genetic barcoding approach to characterize trap-collected pollen from multiple North Dakota apiaries across multiple years. We used the Illumina MiSeq platform to generate sequence scaffolds ...

A 3-yr field survey was carried out in France, from 2002 to 2005, to study honey bee (Apis mellifera L.) colony health in relation to pesticide residues found in the colonies. This study was motivated by recent massive losses of honey bee colonies, and our objective was to examine the possible relationship between low levels of pesticide residues in apicultural matrices (honey, pollen collected...

African honey bees, introduced to Brazil in 1956, rapidly dominated the previously introduced European subspecies. To better understand how hybridization between these different types of bees proceeded, we made geometric morphometric analyses of the wing venation patterns of specimens resulting from crosses made between Africanized honey bees (predominantly Apis mellifera scutellata) and I...

The Western Honeybee is a key pollinator for natural as well as agricultural ecosystems. In the last decade massive honeybee colony losses have been observed worldwide, the result of a complex syndrome triggered by multiple stress factors, with the RNA virus Deformed Wing Virus (DWV) and the mite Varroa destructor playing crucial roles. The mite supports replication of DWV to high titers, which...

The state of the antioxidant system protection honey bees Apis mellifera carnica under action different temperatures in order to optimize temperature regime keep bee colonies indoors during winter was studied. Bee 81–91-day-old worker were transferred from territory Yuriy Fedkovych Chernivtsi National University apiary period sharp changes (the end November) constant conditions buildings (5±0.6...
