AbstractInvasions can be genetically diverse, and that diversity may have implications for invasion management in terms of resistance or tolerance to control methods. We analyzed the population genetics of Russian-olive (Elaeagnus angustifoliaL.), an ecologically important and common invasive tree found in many western U.S. riparian areas. We found three cpDNA haplotypes and, using 11 microsatellite loci, identified three genetic clusters in the 460 plants from 46 populations in the western United States. We found high levels of polymorphism in the microsatellites (5 to 15 alleles per locus; 106 alleles total). Our native-range sampling was limited, and we did not find a genetic match for the most common cpDNA invasive haplotype or a strong confirmation of origin for the most common microsatellite genetic cluster. We did not find geographic population structure (isolation by distance) across the U.S. invasion, but we did identify invasive populations that had the most diversity, and we suggest these as choices for initial biological control–release monitoring. Accessions from each genetic cluster, which coarsely represent the range of genetic diversity found in the invasion, are now included in potential classical biological control agent efficacy testing.

Abstract The elm leaf beetle P. luteola is a serious pest of ornamental elms in most areas where they are grown. This insect is native to southern Europe and was introduced to the USA in the 1800s, but has also reached Central Asia, the Middle East, North Africa and South America and was recently detected in Australia. It feeds on all species of native and introduced elms, including American (Ulmus americana), English (U. procera), Chinese (U. parvifolia) and Siberian elm (U. pumila). Wu et al. (1991) identified elm leaf beetle as the second most important urban tree pest in the western United States and third most important nationally.
