Done that. I look at the pollen for Varroa mites. Find very few. I would guess that varroa hold on pretty tightly, and get inbetween the segments of the bee. Hard to scrape them off.It is an interesting thought. I reckon someone could sift through their trapped pollen and do a count. Any volunteers?
Tells me that most phoretic mites are on bees in the broodnest. Figures. That's where the brood is. Also tells me that it takes only 1 female varroa to infest the next yard down the road...easily accomplished by robbing or drone drift.So, what does that tell ya? I'm not sure. How exactly do varroa get around? How did they get around the state from the time they were first noticed in 1986(?) or '87?
None taken, but I think it's less random than that. If you do an alcohol wash from different locations in the hive, the bees in the central broodnest will have much higher mite counts than the bees at the preiphery.No offense given, but I just think they hop on whoever and wherever shall they go
This is worth reading for some additional information about the Varroa mite.Drone drift...when drones follow a virgin home to her yard and stay. They are accepted into any colony.
Interesting theory, but no one has ever seen a mite on a flower. and it seems like quite a risk to take to get to another hive. What is the incentive to jump off on to a flower that may not get a visit from a bee from another hive?they hold on the best they can & maybe layover for the next flight to another bee yard.
Does 1 pest less a day make a difference?
