    The host is weakened by you eating it; it’s very bad if the host dies due to a secondary infection and the meat you depend on goes off. Given that, excreted antibacterials seem like a sensible evolutionary adaptation.

  2. This kind of wasp/prey relationship was something SJ Gould saw as a deep theological problem that he could not square with belief. See his “Nonmoral Nature” here:

    The anti-microbials aren’t  to protect the roach, that’s been living with the pathogens its whole life, but for the sake of the wasp larvae.  I doubt the gestation period for the wasp is particularly long, and we all know how difficult it is to kill a cockroach anyway.

    I found this sentence touching, at least grading on the cockroach curve:  “The cockroach is both the larva’s only food source and its cradle.”  Of course, mama wasp didn’t bother to ask the roach for permission.

    I also found the fact that someone was able to install a window on a roach every bit as impressive as the fact that they discovered the anti-microbial secretions.  Respect to the glazier!
