Will exposed sunlight kill brood

[brooksbeefarm]

I have been keeping bees since the sixties and have always held frames up in the sunlight to look for eggs, larva, queen, ect. A state rep. said at a meeting that exposing brood to the sun will kill it? Anyone else know about this, is their a time limit maybe? This was a ex president of the Mo. beekeepers Asscociation and no one questioned him at the time,it was a class on raising queens and looking for eggs. Jack

Bees build comb outside. But the brood comb would be on the inside of the combs and protected by nurse bees.

I would guess that short exposure to sunlight has no effect. But longer exposure to sunlight and low-humidity air movements would dehydrate the brood (especially eggs) pretty quickly.

That's how I look for brood and eggs. I've never seen a problem. Of course prolonged exposure might be different...

I have been taught by my mentor, other beeks, state apicurist that to see eggs you rais the frame up at an angle with the sun over your shoulder shining into the cells so that you can clearly see eggs.

FWIW, I still have a hard time seeing eggs in white/light colored comb. :o If I see larva with large larva on the inside and smaller and smaller larva spirling out from the large larva, I figure that the last cells that are shiny (probably from royal jelly) are eggs. Just a SWAG. :lpf:

That's the kind of frames i pick out to start nuc's and haven't had one not make queen cells yet:thumbsup: I get flustered when someone at one of our outings (bee club) hands me a frame of dark comb and say look at all those eggs and i don't see nothing but dark comb.:scratch: Jack
