Varroa mimicrys Honey Bees scent
It is known as an important factor for the ability of Varroa destructor to shift host from Apis cerana AC, to the Honey Bee Apis mellifera, Af, that it can mimicry the chemical properties of the bees cuticula.
Ac and Am differs as seen in the diagram and so does the Vd on the different species. Vd has the ability to adapt its scent depending on its host and also to change depending at what stage the host is, larvae, puppa, young bee, adult bee.
There is an arms race going on where both the victim and the parasite tries to adapt to survive.
This means we will never get rid of the parasite but we can try to find bees that are one step ahead in its defense system.
So how can we find those bees and traits? Bees that for instance show increased activity in their olfactory genes? Hopefully BeeScanning may help screening areas with bees more apt to defend themselves and combining this with the selection stabilizing properties within the population. Eventually modification of genes responsible for those traits may speed up the evolution.
