> Most bees these days have some hygienic traits due to mites and those bees remove diseased larva so fast in my experience I do not see the classic symptoms of EFB such as discolored larva. All I see is empty cells which should have larva in them.
So what makes you diagnose this as EFB rather than, say, inbreeding or queen problems?
