Abstract
Pollination of crop plants is highly valued as it contributes to productivity in terms of quality and quantity. Globally, pollination is valued at more than USD 500 billion. The primary pollinators are insects and amongst them, bees. The Western honeybee (Apis mellifera) is a very generalist pollinator that is managed. Honeybees contribute up to 50% of the pollination of various crop plants. Pollinators are at risk due to land-use/land-cover changes and agricultural pesticide input.
In a recently published study, research on honeybees in runner bean (Phaseolus coccineus L.) in Poland is presented. In one part of the study, the actual foraging of honeybees in beans is recorded, along with the time of day, abundance and time spent on flowers. The second part of the study investigated several apiaries concerning the potential poisoning of bees by means of pesticide exposure. The authors recorded the fitness of colonies, flight activity, behaviour, productivity and pesticide residues in bees.
The manuscript, unfortunately, has several scientific flaws that are outlined in this commentary. These flaws, particularly those related to experimental planning and data collection and analysis, have the potential to compromise the conservation of pollinators. The misguidance in the implementation of measures to protect pollinators and pollination services is a cause for concern and should motivate us to address these issues.
