Yup.  A typo.

Yup. That is how I understand it.  Apparently as the prevalence of hygienic 
behaviour increases in the bee populations, more and more hives pass the 
test.

In my opinion, it is less important to select drastically for very high 
levels of hygienic behaviour than to be certain to set a minimum standard 
and eliminate any hives that are seriously non-hygienic.

Susceptible hives are a menace, since they break down and become reservoirs 
of disease or pests.
