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.

啶虫脒和溴氰菊酯对油菜种植中蜜蜂（Apis mellifera carnica Pollman）死亡率和行为的影响

该研究的目的是确定啶虫脒和溴氰菊酯对同一品种蜜蜂的死亡率和行为的影响，这些蜜蜂来自同一来源并由专业养蜂人估计处于良好状态，但在不同年份和不同条件下天气状况。2012-2018 年在油菜田的田间隔离器中进行的研究结果表明，啶虫脒对蜜蜂的死亡率或行为没有影响。溴氰菊酯的活性不同于通过导致蜜蜂群体死亡和较弱的条件导致群体破坏而缺乏影响。这证明了啶虫脒对蜜蜂的相对安全性以及使用溴氰菊酯的高风险。
