So, it is a general knowledge that the first virgin to emerge will kill the rest of the unhatched virgins. I have 2 questions about that.

1. Does the virgin queen do the deed herself, or does she mark queen cell to be destroyed by the workers. I believe I read somewhere in Dolittle or Smith that the did not do the actual killing.

2. If we remove queen cells into the incubator without workers, can the killing spree be prevented?
