Male bedbugs are known to be very unfussy when it comes to mating, mounting any well-fed bug they can see - regardless of age or gender. Researchers writing in the open access journal BMC Biology have discovered how immature bedbug nymphs, who would be harmed by the traumatic insemination technique practiced by the males, release alarm pheromones to deter this unwanted attention. Vincent Harraca, from Lund University, Sweden, worked with a team of researchers to stage encounters between males...

However, when the queen dies or is re-moved, workers begin laying eggs of their own.

Queen pheromones...
