Untimely loss of Job van Praagh

The bee community has experienced a great loss with the recent death of Dr. Job van Praagh. Honorary Professor at the University of Leibniz in Hanover, Job dedicated his life to research into the biology and eco-toxicology of bees. Straightforward, sincere and honest, the discussions with Job were always intelligent, warm and stimulating. We’ll miss…

In vitro study on enzymatic systems of honeybees

In this study we measured in vitro honey bee enzyme activities in presence of the synergist piperonyl butoxide (PBO) and some new benzodioxole and dihydrobenzofuran derivatives through absorbance and fluorescence spectrophotometric assays, to determine if and to what extent detoxification systems and acetylcholinesterases are affected by these compounds. Both Italian (Italy) and Carniolan (Czech Republic)…

Institutional Beekeeping like that of in NZ &...

Now because of environmental pollution, degraded forest, land fragmentation, urbanization, use of chemical pesticides, unseen bee stress, overfeeding to bees, contaminated bee products,  dearth period malnutrition, massive adulteration, it has become impossible to keep bees for authentic, qualitative and medicinal honey without special apiary site development. Access to land resources, bee forage development, bee breed improvement,…

Origin of antimicrobial properties of propolis

Abstract Natural honey bee products, especially propolis are well known for their biological properties. However, less well known are the impact of propolis’ single phenolic substances and variation across different landscapes, geographic locations and botanical origins. Here, we determined the chemical composition of propolis samples collected in different geographic areas of Romania with a continental…

Microsporidian Nosema neumanni

Abstract The microsporidium Nosema neumanni n. sp., a new parasite of the honeybee Apis mellifera is described based on its ultra-structural and molecular characteristics. Structures resembling microsporidian spores were found by microscopic examination of honeybees from Uganda. Molecular confirmation failed when PCR primers specific for Nosema apis and Nosema ceranae were used, but was successful…
