To HeinzeDJAK and others

Check in to the Journal Insect physiology and biochemistry.  Many
have been done on locust, cockroach and diapausing pupae of leps (H.
cecropia is the best known).  Any general insect physiology book should
have a section on respiration with some of the classical articals
mentioned above.  The rates of diapaused pupae in H. cecropia is very
interesting.  You will find that the spiracles are a very interesting
structure and in some insects only a few are functional like the
larvae.  I am sure that someone on this list is working in Insect
respiration and can give more knowledge on the subject.
Happy hunting,
