Abstract
1.
1. Extracts from each of the fat body, thoracic and appendage muscle of both sexes of the American cockroach yielded a single disc electrophoretic GDH fraction, which was quantitative and qualitatively stable during the first 6 months of the imago.
2.
2. Enzymes extracts from 3 cockroach species were heat stable at 52° for 30 min.
3.
3. GDH patterns were highly species-specific among the 24 cockroach species analyzed. Generic relationships were postulated on the basis of Rf similarity.
4.
4. Clones of parthogenetic Pycnoscelus surinamensis, with modal chromosome complements of 34 to 54, each had a single GDH fraction and all Rf values were identical.
