I'm in complete agreement! Breeding is the long-term solution.
>I'm curious to know what the cost is to do more treatments at a lower kill
rate, as opposed to fewer treatments at a higher kill rate. Any idea what
the difference in cost is?
The cost is minimal when I work it out. We try to piggyback treatment with
other hive openings. When hive income per season is in the $250 range up,
an extra dollar and an extra minute of labor are dollars well spent.
>'m also curious as to what impact that has on your viral loads.
We keep viral loads minimal all season by never allowing varroa to climb
above the 2% infestation rate.
>We hear so often that most matings are brother/sister and that mites are
clones, but are there any data on mating? How often is there just a single
mite mother per cell? How often 2 or 3 or 4
Yes, data exist. Generally only one foundress per cell until mite
infestation rate climbs to a high level.
