Urban bee ecology is an emerging field that holds promise for advancing knowledge of bee community dynamics and promoting bee conservation. Published studies of bee communities in urban and suburban habitats are fewer than those documenting bees in agricultural and wildland settings. As land lost to urbanization is predicted to increase in coming years the necessity of studying urban bee popula...

Acute bee paralysis virus (ABPV) is a small single stranded RNA virus recently classified within the family Dicistroviridae, genus Cripavirus. Here, we describe the first study of ABPV in unhealthy bee colonies, which has been an unusual loss in adult bee population and significant honey bee mortality during the year. The aim of this study was evaluation of ABPV infection in honey bee colonies ...
Honey bees (Apis mellifera anatolica) were subjected to sequential trials where they were given the choice between a feature-positive and a feature-negative feeding plate. The 'feature' being manipulated is the presence of a single blue circle among three circles marking the location of a small sucrose reward. That is, a 'feature-negative' target had three white circles, while a 'feature-positi...
Establishing agricultural product quality safety traceability platform and barcode system have become a worldwide trend. Bee product traceability platform that can be used to identify all aspects from farm to table has been laid out based on China law and global standards. An integrated bee product traceability system which involving all of the process along the supply chain can be applied to i...
The toxicity of pesticides used in agriculture towards non-targeted organisms and especially pollinators has recently drawn the attention from a broad scientific community. Increased honeybee mortality observed worldwide certainly contributes to this interest. The potential role of several neurotoxic insecticides in triggering or potentiating honeybee mortality was considered, in particular phe...
