Currently, the habitat of many species is fragmented, resulting in small local populations with individuals occasionally dispersing between the remaining habitat patches. In a solitary bee metapopulation, extinction probability was related to both local bee population sizes and pollen resources measured as host plant population size. Patch size, on the other hand, had no additional predictive p...

One of the values of biodiversity is that it may provide 'biological insurance' for services currently rendered by domesticated species or technology. We used crop pollination as a model system, and investigated whether the loss of a domesticated pollinator (the honey bee) could be compensated for by native, wild bee species. We measured pollination provided to watermelon crops at 23 farms in N...

New genomic tools and resources are now being used to both understand honey bee health and develop tools to better manage it. Here, we describe the use of genomic approaches to identify and characterize bee parasites and pathogens, examine interactions among these parasites and pathogens, between them and their bee hosts, and to identify genetic markers for improved breeding of more resilient b...

Bee pollen is a natural resource – pollen collected by bees and stored in the beehive with various bee enzymes added as it is a mixture of plants pollen and bee saliva. It is rich source of various nutrients, among them exogenous amino acids. Therefore, it can be a good and natural dietary supplement. New possibilities for bee pollen usage arise every day, yet it can also be a threat. Although ...

Extended Abstract Introduction and Objective: People are sensitive to bee venom and the presence of allergenic compounds in the venom has made it difficult to use and determine the optimal dose for treatment. The aim of this study was to reduce allergenic compounds and to evaluate the quality of gamma ray processed bee venom. Material and Methods: Venom samples were irradiated at dose...

Bee venom therapy is a treatment modality that may be thousands of years old and involves the application of live bee stings to the patient's skin or, in more recent years, the injection of bee venom into the skin with a hypodermic needle. Studies have proven the effectiveness of bee venom in treating pathological conditions such as arthritis, pain and cancerous tumors. However, there has not b...

Dissecting diversity patterns of organisms endemic to Iberia has been truly challenging for a variety of taxa, and the Iberian honey bee is no exception. Surveys of genetic variation in the Iberian honey bee are among the most extensive for any honey bee subspecies. From these, differential and complex patterns of diversity have emerged, which have yet to be fully resolved. Here, we used a geno...

controversial immunomodulatory properties of bee venom (bv) have provided an appropriate field for more investigation. the aim of present research was to verify the effects of honeybee venom on matrix metalloproteinase activity and interferon production as well as cell proliferation in monocyte and fibroblast cell lines. the monocyte and fibroblast cell lines (k562, ht-1080, wehi-164) were used...

the aim of this research was to construct an equipped hive with the acquisition, communication and analysis systems to send images on-line, wirelessly. this system could be used to evaluate density of bee colonies and also work as bait box to eliminate bee pest, if necessary. in this study, two methods, optical flow and neighborhood gray-tone difference matrix, were used to determine hive condi...
