The Northern Great Plains region of the US annually hosts a large portion of commercially managed U.S. honey bee colonies each summer. Changing land use patterns over the last several decades have contributed to declines in the availability of bee forage across the region, and the future sustainability of the region to support honey bee colonies is unclear. We examined the influence of varying ...

Alopecia is an important issue that can occur in people of all ages. Recent studies show that bee venom can be used to treat certain diseases including rheumatoid arthritis, neuralgia, and multiple sclerosis. In this study, we investigated the preventive effect of bee venom on alopecia, which was measured by applying bee venom (0.001, 0.005, 0.01%) or minoxidil (2%) as a positive control to the...

Software test suite optimization is one of the most important issue in software testing as testing consumes a lot of time in executing redundant test cases. In this paper, we have proposed and implemented a new approach for test suite optimization, namely, Mutated Artificial Bee Colony. Artificial Bee colony algorithm combines local search carried out by employed and onlooker bees with global s...

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...

Chemical miticides are used routinely in honey bee colonies worldwide as treatment for the parasitic mite Varroa destructor, but there have been very few long-term colony-level field studies of impacts on bees themselves. Lab-based with individual or small groups highlighted many negative effects behaviour and physiology; hence, is an urgent need to better understand consequences apicultural se...
