“…The three other haplotypes, H2, H3 and H4, are originated from Australia. Our results suggest that one G. brimblecombei invasion events occurred in Brazil and it was probably originated from locals previously invaded as USA, Mexico or Chile and not from Australia, origin geographic region, as already reported for other pests in Brazil (Nadel et al, 2010;Dittrich-Schröder et al, 2018;Bortolotto et al, 2019;Cordeiro et al, 2019;Ferronato et al, 2019).…”

“…Intraspecific diversity studies, using both mitochondrial and nuclear markers, enable us to evaluate the population genetic structure and genetic diversity of a species (Ferronato et al, ; Johnson, Morton, Schemerhorn, & Shukle, ; Roman, ; Wang et al, ). Although P. americana is an urban pest worldwide, there are limited studies on the genetic variety and population structure of P. americana .…”

The American cockroach (Periplaneta americana) is a globally invasive pest that can cause significant economic loss and threaten human health. Although it is abundant and lives in close proximity to humans, few studies have investigated the genetic diversity of P. americana. Our study analyzed 1,053 P. americana and other Periplaneta species' samples from different locations in China and the United States. A traditional tree‐based method using 17 unique mitochondrial COI haplotypes of P. americana and 20 haplotypes of the other Periplaneta species accurately identified P. americana with a barcoding threshold of 5.1%. To identify the population genetic structure of P. americana, we investigated wingless gene and pooled them with obtained mtDNA data for a combined analysis. Although the genetic diversity of the USA group was relatively higher than the China group, the number of haplotypes and alleles of both groups was small. The analysis of molecular variance (AMOVA), intraspecific phylogeny, and haplotype networks indicated that P. americana had very little global genetic differentiation. The weak geographic genetic structure might reflect the human‐mediated dispersal of P. americana. Despite no apparent phylogeographic assignment of mtDNA and nuclear lineages was observed in both BI trees, the integrated COI sequence data identified four distinct P. americana haplotype groups, showing four ancient maternal lineages of P. americana in China and the United States.

“…As Europe and Brazil were not as heavily sampled as the U.S. in this study, there may be unaccounted population structure at play. A study using the mitochondrial COI sequence of D. suzukii from 12 Brazilian sample sites found only 5 haplotypes but did observe evidence of population structure by geography, suggesting a single invasion event with subsequent expansion (Ferronato et al 2019). Alternatively, these low diversity levels, combined with the fact that no admixture events directly to Europe or Brazil were detected in Treemix, could mean that European and Brazilian populations will have limited ability to adapt, which can be beneficial for control strategies.…”

Drosophila suzukii, or spotted-wing drosophila, is now an established pest in many parts of the world, causing significant damage to numerous fruit crop industries. Native to East Asia, D. suzukii infestations started in the United States a decade ago, occupying a wide range of climates. To better understand invasion ecology of this pest, knowledge of past migration events, population structure, and genetic diversity is needed. To improve on previous studies examining genetic structure of D. suzukii, we sequenced whole genomes of 237 individual flies collected across the continental U.S., as well as several representative sites in Europe, Brazil, and Asia, to identify hundreds of thousands of genetic markers for analysis. We analyzed these markers to detect population structure, to reconstruct migration events, and to estimate genetic diversity and differentiation within and among the continents. We observed strong population structure between West and East Coast populations in the U.S., but no evidence of any population structure North to South, suggesting there is no broad-scale adaptations occurring in response to the large differences in regional weather conditions. We also find evidence of repeated migration events from Asia into North America have provided increased levels of genetic diversity, which does not appear to be the case for Brazil or Europe. This large genomic dataset will spur future research into genomic adaptations underlying D. suzukii pest activity and development of novel control methods for this agricultural pest.
