Bed bugs protect their sperm from bacteria

Bed bugs protect their sperm against sexually transmitted infections by producing germ-busting ejaculates, scientists have found.

Bacteria covering bed bugs’ bodies are transmitted to the female, along with the sperm, during mating.

The new work shows that without the protection of antibacterial agents in the bug’s ejaculate, 40% of sperm die.

The results were presented at the 13th Congress of the European Society for Evolutionary Biology.
