Interpretive Summary:

Technical Abstract: Several flea beetle species from the genus Aphthona (Coleoptera: Chrysomelidae) have been introduced into North America as biological control agents for the rangeland weed, leafy spurge (Euphorbia esula L.). Three brownish colored species and two black species were released at many locations beginning in 1988. The morphological distinction of the brown species adults is difficult and many recent redistributions of the beetles for biological control have not kept track of the individual species. It is not possible to discern any of the species from larval morphology. Portions of the mitochondrial genome were used order to measure the genetic diversity of the established North American populations. PCR-RFLP of a large segment of mtDNA (~8000 base pairs) and nucleotide sequencing of a smaller segment of the mitochondrial cox1-cox2 region (~575 base pairs, GenBank Accession numbers DQ386423-DQ386434) were both examined. Different mtDNA haplotypes were determined via the PCR-RFLP. The small mtDNA segments were cloned and sequenced from an example of each haplotype. Not all of the long PCR-RFLP haplotypes exhibited polymorphism for the short sequence. Since some combinations of restriction sites in the smaller sequence appear to be species specific, the sequences provide effective molecular identification of the species.
