Abstract
The aim of the research was to determine the influence of acetamiprid and deltamethrin on the mortality and behaviour of honeybees of the same variety, coming from the same source and estimated to be in good condition by a professional beekeeper, but in different years and under different weather conditions. Results of research conducted in field isolators in oilseed rape fields in the years 2012–2018 showed no acetamiprid influence either on the mortality or on the behaviour of honeybees. Deltamethrin activity differed from a lack of influence through causing mortality and a weaker condition of honeybee colonies to the destruction of the colony. This demonstrates the relative safety of acetamiprid to honeybees and the high risk of deltamethrin use. The differences in the bee colonies’ reaction to deltamethrin are probably caused by the high acute toxicity of this active ingredient, genetically dependent, variable metabolic capabilities of particular bee colonies, or coexistence of a variety of different stressors—mainly pathogens.
Highlights
During recent years, many European countries have conducted broad research on the wellbeing, safety and health of honeybees (Apis mellifera )
In the case of deltamethrin, the results show that its use may be dangerous for bees, the insects are equipped in detoxification mechanisms enabling metabolism of the toxin
Honeybees’ reaction to deltamethrin was different depending on the year of the experiments
Summary
Many European countries have conducted broad research on the wellbeing, safety and health of honeybees (Apis mellifera ). It results from an apparent decrease in the pollinators’ population density in many ecosystems and from the lack of a reasonable explanation of the aetiology of the colony collapse disorder (CCD) (Vanengelsdorp et al 2009). In public opinion as well as in many scientific environments, chemical plant protection products are indicated as one of the main factors responsible for CCD. The European Food Safety Authority (2013) proposed a “Guidance Document on Risk Assessment of Plant Protection Products on Bees”. Uniform scientific methods have not been accepted yet and so research in different countries is still carried out with the use of different methods (EFSA 2013)
