The activity of Cinnamomum zeylanicum Nees essential oil (cinnamon oil) against Paenibacillus larvae (Withe) was evaluated in the laboratory and in a field experiment in order to improve the biological control of the Apis mellifera L. disease American foulbrood (AFB). The MICs (Minimal Inhibitory Concentration) against P. larvae were determined by the tube dilution method. Bee lethality was est...
متن کاملInvestigation of Bioclimatology Factors on Prediction of Honeybee Performance in Climate Change Conditions (Case Study: Shahindej)

Considering the advanced climate change, the impact of climate indicators on livestock production can present an important challenge for producers. The prediction of crop yields is one of the most important issues in the food security debate to increase the economic efficiency of livesto...
متن کاملSpatial distribution of Vespa velutina individuals hunting at domestic honeybee hives: heterogeneity at a local scale.
Since its recent introduction into Europe, the yellow-legged hornet, Vespa velutina, has become a major predator of the domestic honeybee, Apis mellifera, but little is known about its hunting behavior. We studied V. velutina hunting behavior by a capture-mark-recapture procedure in an experimental apiary. A total of 360 hornets were captured and tagged, and we determined: (i) the number of hor...
متن کاملComparative sublethal toxicity of nine pesticides on olfactory learning performances of the honeybee Apis mellifera.
Using a conditioned proboscis extension response (PER) assay, honeybees (Apis mellifera L.) can be trained to associate an odor stimulus with a sucrose reward. Previous studies have shown that observations of conditioned PER were of interest for assessing the behavioral effects of pesticides on the honeybee. In the present study, the effects of sublethal concentrations of nine pesticides on lea...
