A New Method for Quick and Easy Hemolymph...

Abstract Bio-analysis of insects is increasingly dependent on highly sensitive methods that require high quality biological material, such as hemolymph. However, it is difficult to collect fresh and uncontaminated hemolymph from adult bees since they are very active and have the potential to sting, and because hemolymph is rapidly melanized. Here we aimed to develop…

Pesticide Poisoning of Honeybees: A Review of Symptoms,...

Abstract During the 2000s, the problem of pesticide poisoning of honeybees seemed to be almost solved. The number of cases has decreased in comparison to the 1970s. The problem of acute honeybee poisoning, however, has not disappeared, but instead has transformed into a problem of poisoning from ‘traditional’ pesticides like organophosphorus pesticides or pyrethroids, to…

Identification of nanoparticles on the surface of thorax,...

Abstract The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the frst time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and confrmed by Atomic Force Microscopy (AFM). Our study clearly denotes that the Indian rock honey bee Apis…

Honey bees exposed to sub-lethal doses of imidacloprid...

Abstract In this study, different context-dependent effects of imidacloprid exposure on the honey bee response were studied. Honey bees were exposed to different concentrations of imidacloprid during a time period of 40 days. Next to these variables, a laboratory-field comparison was conducted. The influence of the chronic exposure on gene expression levels was determined using…
