In the search of alternatives for controlling Aethina tumida Murray, we recently proposed the BAA trap which uses boric acid and an attractant which mimics the process of fermentation caused by Kodamaea ohmeri in the hive. This yeast is excreted in the feces of A. tumida causing the fermentation of pollen and honey of infested hives and releasing compounds that function as aggregation pheromone...

Honeybee hives may influence pollen and nectar availability in natural ecosystems, which consequently affect wild pollinators. We studied the effects of managed honeybee on bee diversity Villavicencio Nature Reserve (Mendoza, Argentina). placed pan traps at increasing distances from to estimate abundance, richness, composition. Wild abundance did not change detectably with distance hives, altho...

A study was conducted to investigate honeybee colonies absconding from beehives and its financial implication among beekeepers in Tabora and Katavi regions, Western Tanzania. Four districts were selected on the basis of adoption of improved beehives. A total of 198 beekeepers were randomly selected for interviews. Data collected from beekeepers using a questionnaire were supplemented with data ...

Toxicity effects of the neonicotinoid insecticides clothianidin, imidacloprid, and thiamethoxam were tested in the laboratory on different honey bee (Apis mellifera L.) genotypes belonging to the following subspecies: Apis mellifera mellifera L., Apis mellifera ligustica Spinola, and Apis mellifera carnica Pollmann. Oral and indirect contact trials were carried out on adult worker honey bees fo...

Honey bee colonies are subject to numerous pathogens and parasites. Interaction among multiple pathogens and parasites is the proposed cause for Colony Collapse Disorder (CCD), a syndrome characterized by worker bees abandoning their hive. Here we provide the first documentation that the phorid fly Apocephalus borealis, previously known to parasitize bumble bees, also infects and eventually kil...

Honeybees are effective monitors of environmental pollution. The objective of this study was to summarize tritium en) concentrations in bees and honey collected from within and around Los Alamos National Laboratory (LANL) over an 18-year period. Based on the long-term average, bees from nine out of eleven hives and honey from six out of eleven hives on LANL lands contained H that was significan...
