	Keeping adult flies in a vial or bottle with no food & a dampened
kimwipe for 24 hours is an effective (I think) method for getting them to
empty their guts.

	As for RAPD in particular, no, I don't know of any studies in
Drosophila. There are several USDA grantees who are using RAPD in other
insects, including Ceratitis, and their experiences may be instructive.
Perhaps in bionet.molbio.rapd you'll find more information?

	I have little doubt that (CA)n-containing interspersed micro-
satellite repeats of the type found in mammalian DNA are also present in
the Drosophila genome. That they may be useful as polymorphic markers is
supported by Kafatos' use of (CA)n-repeats to make a X-chromosome linkage
map for the malaria vector Anopheles gambiae (1993, Science 261: 605-608).
