Genetic differentiation of T rialeurodes vaporariorum ( W estwood 1856) populations was examined using biochemical and allozyme analysis. For biochemical analysis, general esterase and glutathion‐ S ‐transferase were tested. Allozyme genetic variability in 11 populations of T . vaporariorum was investigated using five loci from four enzyme systems. Although there are large variations between populations, T . vaporariorum is grouped into two populations with geographic barriers, based on N ei's genetic distance in the B aekdudaegan M ountains. Within these two groups, low migration and linkage disequilibrium reveal that populations tend to be influenced by gene drift rather than uniform selection pressures. The effect of genetic drift is greater than the effect of uniform selection by insecticides or host plant resistance, which is suggested by the F ST estimates in this study. Based on this basic research, more effective whitefly control programs could be built in the future.
