Hello Bob and all.
I am a beekeeper and researcher in Brazil, Amazon Basin.
I have always worked with AHB until 1999. At this year I began to work with
EHB hybridized as Africans drones. In the principle the bees grow very well.
After one year I perceived some signals of high infestation by Varroa. The
symptoms were typical of Varroa syndrome.
When I investigated many pupa brood I saw lots of them with black abdomen. I
do slides and bacteria wasn't found. I don't after perceived it in the AHB
because they don't get Varroa syndrome easy. In many AHB I perceived spot
brood and when it were treated with terramicina the symptoms disappeared.
In AHB the Varroa infestation is not a problem but the viruses transmitted
by mite is so great problem. In the European bee the problem is two fold,
Varroa infestation and Varroa syndrome (viruses).
