The impact of pathogens on this decline may be particularly important in conjunction with the accumulation of pesticide

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...

lt has been shown that drone larvae can develop from fertilized eggs (Woyke, l963a):Results described in a more recent paper (1965), together with those not.yet published, enable us to refer to them as diploid drones

Reports of honey bee population decline has spurred many national efforts to understand the extent of the problem and to identify causative or associated factors.

Many factors can negatively affect honey bee (Apis mellifera L.) health including the pervasive use of systemic neonicotinoid insecticides.

The continuing need for novel and selective insecticides acting on pests has led to the development of new groups of compounds. The newest major group of insecticides are the neonicotinoids, which include imidacloprid, acetamiprid, and thiamethoxam

The effect of sublethal doses of imidacloprid on protein content and activity of proteases on honey bees was analyzed.

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.

Agrochemical products and other classes of contaminants, such as trace elements and polycyclic aromatic hydrocarbons, contribute to the general decline of bees’ populations.

Imidacloprid is a neonicotinoid pesticide heavily used by the agricultural industry and shown to have negative impacts on honey bees above certain concentrations. We evaluated the effects of different imidacloprid concentrations in sugar syrup using cage and field studies, and across different environments.
