Bees are used to pollinate plants in isolation cages. Usually the bees have previously flown about freely in the open air and may have gathered pollen from the same plant species.
Now the question arises whether the bees can contaminate with this pollen plants with which they are enclosed in an isolation cage. In this connection a number of experiments were undertaken to find out how long bees are loaded with germinable pollen. It appeared that the risk of contamination was practically eliminated by keeping the bees in a house or empty isolation cage for 12 hours.
