The honeybee pupae development influences its future adult condition as well as honey and royal jelly productions. However, the molecular mechanism that regulates honeybee pupae head metamorphosis is still poorly understood. To further our understand of the associated molecular mechanism, we investigated the protein change of the honeybee pupae head at 5 time-points using 2-D electrophoresis, m...
This paper examines the potential effect of decreasing honeybee population on crop prices by estimating the relationship between honeybee population and the price of almonds over time. As a declining honeybee population becomes an increasingly salient issue, the public must be aware of the potential impacts that honeybee population loss can have on society, including rising crop prices. Underst...
The honeybee is a social insect that exhibits various social behaviors. To elucidate the neural basis of honeybee behavior, we detected neural activity in freely-moving honeybee workers using an immediate early gene (IEG) that is expressed in a neural activity-dependent manner. In European honeybees (Apis mellifera), we identified a novel nuclear non-coding RNA, termed kakusei, as the first ins...
Nuclear mitochondrial pseudogenes (numts), which originated from mitochondrial DNA (mtDNA) insertions in the nuclear genome, have been detected in many species. The distribution of numts in the honeybee nuclear genome has not yet been fully reported. By referring to the whole honeybee mtDNA sequence and to the recent version of the honeybee nuclear genome, 236 reference sequences were identifie...
The microorganisms Ascosphaera apis, Paenibacillus larvae and Melissococcus plutonius are the three most important pathogens that affect honeybee brood. The aim of the present study was to evaluate the prevalence of these pathogens in honeybee colonies and to elucidate their role in the honeybee colony losses in Spain. In order to get it, a multiplex polymerase chain reaction (PCR) assay was de...
This paper describes a multi-robot system designed to use Bluetooth wireless communication to solve the “Honeybee” task. The Honeybee task is a simple search and navigation problem that requires a “guide” robot to lead another “blind” robot to a specific target within the environment. Topics discussed include advantages and disadvantages of using Bluetooth in robotics, as well as a variety of b...
For the identification of phylogenetic characteristics of honeybee populations, sampling was conducted from 31 provinces of Iran in spring and summer 2016. Phylogenetic characteristics were evaluated based on mitochondrial ND2 gene. The intergenic regions between ND2 and COI genes were compared in different populations of honeybees. After sequencing and alignment of the genes, the relationships...
Over the past fifty years, annual honeybee (Apis mellifera) colony losses have been steadily increasing worldwide. These losses have occurred in parallel with the global spread of the honeybee parasite Varroa destructor. Indeed, Varroa mite infestations are considered to be a key explanatory factor for the widespread increase in annual honeybee colony mortality. The host-parasite relationship b...
Turkey, with its rich flora and high endemism proportion in a temperate zone, is highly favorable for beekeeping. In the studied area, two honeybees are present: Apis mellifera anatoliaca Yığılca local honeybee, which has been determined as ecotype of Black Sea region. The main objective this study was to determine botanical sources honey samples, produced by these honeybees, from Akçakoca dist...
An important and fundamental step in breeding honeybees is the separation of honeybee populations in Iran. During the years 1992-1996, several research works were directed towards the investigation of genetic populations of the Iranian honeybee (Apis mellifera L.), using biochemical methods. For this purpose, samples of worker bees were taken from 251 colonies of 115 apiaries in 84 cities in 21...
