Abstract

Inheritance patterns of mannose phosphate dehydrogenase (MPI), phosphoglucose isomerase (PGI), and isocitrate dehydrogenase (IDH) were investigated in the potato tuberworm moth, Phthorimaea operculella (Zeller), using starch gel electrophoresis. IDH and PGI are each controlled by two codominant alleles and MPI by three codominant alleles and all three loci are autosomal and unlinked to one another. IDH and PGI are dimeric proteins and MPI is monomeric. Comparison of a laboratory and a field population revealed lower variability in the former. Neither population was in Hardy-Weinberg equilibrium at the MPI locus.
