A report just published in Science magazine (March 19, 2010, p. 1443, full
report p.1506-1509) describes competition among drone sperm in the honeybee
queen (and polyandrous ant queen) reproductive tract.  Seminal fluid from a
drone will impede rival sperm, even that of a brother drone.  Spermathecal
fluid eliminates this effect, so that the rival sperm can coexist in the
spermatheca.

My comment:  perhaps this finding has implications for AI of queens in which
the donor drone sperm has been mixed from several drones.
