Minnesota Hygiene Queen Pin Killing of Brood |
Hygienic Behaviour in Honey Bees |
|---|
There are several ways in which we can investigate this property in honey bees.
Pin killing brood in a rosette pattern.
Pin killing brood in a diamond or rhombic pattern.
Whichever pattern is used, pin killing has a serious drawback. The pin leaves a hole, only
a small hole, but this renders the comparison with sealed cells invalid. As the aroma
leaking through the hole itself will be many times greater than the level of smell that
the bees would have to detect if the capping was sound.
Freezing brood using liquid nitrogen is described in the "Minnesota hygiene queen" page in the menu at top left.
