Hello Todd and All,
1) Am I correct in assuming that the majority of varroa infestation in the
U.S. is V. Jacobsoni?
No Varroa destructor
2) Is V. Destructor here as well?
All I have ever seen as been V.d.but we were told for years that VD was VJ.
3) Are there physical/behavioral differences between the two which would
suggest differences in treatment?
Yes
-----> How do we tell the difference?
VD is oblong and VJ is oval
There are many strains even within VD and VJ I am told. We really only now
are learning a great deal about varroa . There are several other mites which
infest bees which are not (yet) found in the U.S.
