Nowierski, Gregory J. McDermott, Joseph E. Bunnell, Bryan C. Fitzgerald, Zheng Zeng] Isozyme analysis using starch gel electrophoresis was used to examine possible genetic differences among populations of 4 Aphthona species which were associated with 4 different Euphorbia species and 4 different environmental types in Europe. Aphthona species evaluated in the study included A. cyparissiae (Kock), A. flava Guillebeau, A. lacertosa Rosenhauer, and A. nigriscutis Foudras. Euphorbia host plant species considered in this study included E. cyparissias L., E. esula L., E. lucida Waldstein-Wartemberg and Kitaibel, and E. virgata Waldstein-Wartemberg and Kitaibel. Cluster analysis of genetic distances obtained from isozyme analysis easily distinguished populations of the 4 flea beetle species as 4 distinct groups. Based on the dendrogram generated from cluster analysis, populations of A. lacertosa and A. nigriscutis were found to be more similar genetically than either species to populations of A. flava or A. cyparissiae. The greatest genetic distance was found between populations of A. cyparissiae and A. lacertosa, which occur in different habitats and on different spurge species. A relatively high genetic distance also was found between populations of A. cyparissiae and A. nigriscutis, which are species that occur in similar habitats and on similar spurge species. Measurable degrees of genetic variability were found between populations (within a species) for 2 of the 4 Aphthona species sampled. © 1996 Entomological Society of America Genetics nationallicence Aphthona spp nationallicence Euphorbia spp nationallicence leafy spurges nationallicence isozyme-allozyme analysis nationallicence environmental type nationallicence Nowierski Robert M. aut McDermott Gregory J.
