After more than 70 years, a great mystery of zoology has been solved: Honeybees actually use different dance dialects in their waggle dance. Which dialect has developed during evolution is related to the radius of action in which they collect food around the hive. This is reported by research teams from the Bio-center of Julius-Maximilians-Universität … More Honeybee dance dialects.
A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season. Christian Krupke, professor of entomology, and then-postdoctoral researcher Elizabeth Long … More Honeybees pick up ‘astonishing’ number of pesticides via non-crop plants.
Pesticides significantly reduce the number of pollen grains a bumblebee is able to collect, a new University of Stirling study has found. The research, conducted by a team in the Faculty of Natural Sciences, found that field-realistic doses of a neonicotinoid pesticide affects the behaviour of bees — ultimately interfering with the type of vibrations … More Pesticides may cause bumblebees to lose their buzz, study finds.
Scientists are reporting deep new insights into whys and hows of the famous caste system that dominates honey bee societies, with a select few bee larvae destined for royalty and the masses for worker status. Their study probing the innermost biological makings of queen bees and worker bees appears in ACS’s Journal of Proteome Research. Jianke Li and colleagues … More Queen bee or worker bee? New insights into honeybee society caste system.
Flower losses due to shrinking habitats and climate change hurt prime pollinators. Without enough sugar in their diets, bumblebee queens can experience difficulty reproducing and shorter lifespans. Hollis Woodard, assistant professor of entomology at UCR, has conducted multiple studies showing how loss of plant availability negatively affects the prolific pollinators. Previous research indicates a queen’s diet can impact how quickly her brood develops, … More Sugar-poor diets wreak havoc on bumblebee queens’ health.
Beekeepers across the United States lost 40.7% of their honey bee colonies from April 2018 to April 2019, according to preliminary results of the latest annual nationwide survey conducted by the University of Maryland-led nonprofit Bee Informed Partnership. Honey bees pollinate $15 billion worth of food crops in the United States each year. The survey … More U.S. beekeepers lost over 40 percent of colonies last year, highest winter losses ever recorded. Results point to a need for increased research, extension, and best management practices.
