The two campus hives which were discovered to have been exposed to pesticide poisoning were opened. The commercial hive appears to have normal activity inside. The numbers of bees looks very good and this hive should recover, if the poison exposure is over. The top super is full of bees and full of stored honey. A through search for the queen revealed nothing. I did see newly laid eggs. I will perform a follow up 3 days later to look for the queen again and or simply the presence of eggs.
The adjacent colony which was a wild caught swarm from the Wild17 genetics and subsequently re-queened with the Wild CA18 genetics does not look good at all. A quick inspection of the top box showed numerous bees which were in the final stages of poison exposure. These bees displayed uncontrollable twitching and spastic movements. This hive will most likely not survive the poison exposure. I did not remove any more than just one frame from the top box. I will leave this colony alone for now.
