Onderzoekingen over de wijze waarop de honingbij haar voedsel verzamelt

Minderhoud, A.
Bees were kept in an indoor hive and could reach the outside only through a glass-covered low gallery. In the middle of this was a passage 5 cm. wide, closed by 2 parallel elastic bands. A light push on the elastic was sufficient to restrain her, to mark her or to sample (with a needle) some pollen from her she collected. The species of the pollen was identified. Most bees spent the whole day on one plant species and repeated this several days. Water collectors were marked at the drinking place. They spent the whole day collecting water from one site. By bringing their tongues momentarily into contact with pollen during drinking, these bees suddenly changed their behaviour. They no longer looked for water at the drinking place but for the sweet material they had encountered. They returned to saucers of sugar syrup for days on end. These and complementary observations showed that the environment of the worker bee was extraordinarily limited. Her behaviour was primarily determined by habit.
