entombment

Excerpt from this independent report - I cannot confirm the person or the material, and will update this posting if possible:

".....Pettis tells the MPs that he and Penn State University researcher Dennis van Engelsdorp had discovered the bees have the capability to detect pesticide residues in the pollen. Once they bring the pollen back to the hive and detect pesticide residues, they isolate it from the other pollen in the colony. They use propolis to seal up wax cells full of pollen to put it out of use and protect the rest of the hive from their contents. The pollen stored in the sealed-up cells was found to contain dramatically higher levels of pesticides and other potentially harmful chemicals than the pollen stored in neighboring cells, which is used to feed growing young bees.
“This is a novel finding, and very striking,” Pettis said.
