Abstract

Estimates of genetic differentiation of Plutella xylostella subpopulations (FST) based on electrophoretic variation at four polymorphic loci varied from 0.038-0.028. Using Wright's method, estimates of the number of migrants exchanged per generation per population (Nem) from FST estimates based on four loci ranged from 6-9. There was little variation between islands, and only slightly more variation between Hawaiian populations and two populations from the continental United States. Local variation in insecticide resistance among Hawaiian diamondback moth populations is not an indication of restricted gene flow and is most probably a result of local variation in selection. -from Authors
