Frames collected from a hive that have collapsed during winter time.

Frames collected from a collapsed hive during winter time.

AFB and EFB test have resulted negative.

Pic 1. The majority of the cells in the center of the frame are empty brood cells. There are capped brood cells that don't show a well defined pattern. The brood inside that cells is chilled out (Pic 4). There is a honey reservoir on the top left hand corner. There are white cells in small quantity in several frames (Pic 3). Between the honey store and the brood cells there is an area of orange cells not capped which content is unknown to me.

Pic 3. It can bee appreciated the head of dead bees out of the brood cell. On the left the yellow cells.

Pic 4. Head of a bee inside a capped brood cell. The bee is chilled out. When I collected the frame I noticed that the frame was unexpectedly cold for being a frame with brood. Some of the bees had their heads out of the capped cells but they were dead.

Pic 5. Dead larvae inside chilled out cell.

Pic 6. The orange uncapped cells.

Pic 7. The yellow uncapped cells.

Pic 8. The white cells.

Pic 8. Another white cells which content seems to indicate that the white stuff is formed from a larvae.

Pic 9. Detail of the content of a white cell.

Pic 11. Detail of the content of white cell.

Conclusion: This hive remained weak at the end of last Autumn, the bees have chilled out due to bad weather conditions. The hive didn't grow as the same speed as the others and the bees didn't show much activity in summer time; examining empty brood cells, they don't look as clean as the empty brood cells of the survivor colony so there is the doubt of the white cells being caused by poor housekeeping.
