“…Onion production fields were sampled within Toombs and Tattnall counties from spring 2004 through spring 2013 exactly as described by Sparks et al (2011). The data for percent T. tabaci across all location was from the Sparks et al (2011) study plus sample years 2011-2013.…”

“…Although T . tabaci is the most important pest in onion [ 5 ], other thrips species have been found on onion as well [ 28 ]. It is important to know which thrips species affect onion, their genetic diversity and distribution around the world, as well as the seasonal dynamics in the populations and the reproductive mode to develop improved control strategies to be implemented in future Integrated Pest Management programs [ 29 ].…”

Thrips are a serious pest in many crops. In onion cultivation, Thrips tabaci is the most important, but not the only thrips species causing damage. We investigated which thrips species affects onion and related species worldwide, how much genetic variation there is within T. tabaci populations, and how this evolves. Furthermore, we determined the reproductive mode and the correlation between the genetic and geographic distances. Thrips samples from infested onions or related species were obtained from 14 different locations worldwide. Species and haplotypes were determined through DNA barcoding with the mitochondrial Cytochrome Oxidase subunit I (COI) gene. Thrips tabaci was the most commonly observed species, but Scirtothrips dorsalis, Thrips palmi, Frankliniella intonsa, Frankliniella occidentalis and Frankliniella tenuicornis were also found, especially at the beginning of the growing seasons and depending on the location. The Nei’s genetic distance within T. tabaci was less than 5% and the haplotypes were clustered into two phylogenetic groups, each linked to a specific mode of reproduction, thelytokous or arrhenotokous. Thelytokous thrips were more common and more widely distributed than arrhenotokous thrips. A high percentage of heteroplasmy was detected in the arrhenotokous group. Heteroplasmic thrips were only found in populations where thelytokous and arrhenotokous were present in sympatry. Some T. tabaci haplotypes were present in high frequency at several sampled locations. No correlation was found between the genetic and geographic distances, which points to anthropic activities spreading thrips haplotypes throughout the world.

“…ACB and ECB made the host shift to maize independently around 500 years ago (Alexandre et al, 2013;Calcagno et al, 2017). The ECB cline in North America formed within 100 years of its introduction from Europe between 1910 and 1920 (Brindley & Dicke, 1963;Caffrey, 1919;Showers et al, 1975;Sparks & Young, 1971;Vinal, 1917). History of the ACB cline is less clear, but adoption of maize cultivation over time across China was documented in historical records (Chen & Kung, 2016).…”

Elucidating the genetic mechanism of adaptive response to new environmental challenges is one of the fundamental goals in modern evolutionary biology Sutherland et al., 2013;Williams et al., 2017). Phenotypic and genetic changes along a geographic transect (cline) are thought to be responses to spatially varying selection. When such changes repeatedly occur, for example along another cline, it provides especially strong evidence that those reused targets of selection are at the core of the
