If I understand correctly, you suggest that a parasite would sacrifice "long term survival" or "offspring adulthood probability" to achieve increased reproductive success!?

Hmm, the host could for example go on a "raping spree" but it unsure how this would lead to _significantly_ increased reproduction (I suppose this is an energetically costly enterprise) and why the raping spree wouldn't be already an "integrated" behavior if it were so successful.
