Researchers at the Goethe University in Frankfurt have conducted the first comprehensive study of honey bee behavior in honeycomb cells, using high-resolution images and videos. The team, led by biologist Paul Siefert, aims to raise public awareness of social processes in bee colonies and has made the images publicly available. The study also reveals that certain pesticides, specifically neonicotinoids, change the behavior of nurse bees, leading to reduced larvae feeding and extended development time. This longer development time could increase the risk of bee pest infestation. The researchers have also observed bees feeding larvae mouth-to-mouth and are investigating the effects of neonicotinoids on the quality of the food provided by nurse bees.
