Genetic pattern of the sycamore lace bug (Corythucha ciliata Say. 1832).

Abstract

The sycamore lace bug (Corythucha ciliata Say. 1832) is native to North America, but the species had a rapid expansion throughout Europe after it was introduced into Italy in 1964. Genetic tools have been widely used to find the geographic origin of the invasive species, and to reconstruct the possible invasion routes. We analysed 117 individuals of 22 sycamore lace bug populations in Europe and North America using the 546 bp fragment of the mtDNA gene COI. We identified 8 haplotypes, 5 of which were unique. Haplotype diversity was higher in the native area than in the invaded area. The low diversity and the mismatch distribution found in the non-native area suggest the introduction was a single event.
