Abstract

Gel electrophoresis was used to study isoenzyme variation in Panolis flammea Denis Schiffermüller from a total of eight forest sites in England and Scotland dominated by either Scots or lodgepole pine. Four polymorphic loci (esterase, malate dehydrogenase, isocitrate dehydrogenase and 6-phosphogluconate dehydrogenase) were examined in adult moths. Most of the genotype frequencies conformed to Hardy-Weinberg expectations. An estimate of standardized gene frequency variance (Fst=0.109 ±0.032) indicated that there was significant genetic differentitation between populations. There was in addition a latitudinal cline in allele frequency at the 6-phosphogluconate dehydrogenase locus. The possible role of variation between P. flammea populations in contributing to regional differences in pest status is briefly discussed.
