Re: Light Cycle Experiments?

["Daniel S. Katz" <dskatz at optonline_net>]

Tony, it was Jules Markofsky and Jonathan Matias who did work on the effect
of light cycle ( that the parents were exposed to) on the diapause of N.
guentheri eggs.  Charlie Nunziata summarizes that work as well as their work
on the effect of temperature on the eggs themselves in an article in the
January/February 1989 issue of JAKA ( Volume 22, No.1).
