Host-associated genetic differentiation in Thrips tabaci (Insect; Thysanoptera), as determined from mtDNA sequence data

Article Abstract:

The host-associated genetic differentiation in 22 populations of tabaci collected from tobacco and leek, respectively were tested. Clustering analyses and haplotype networks based on sequence variation at a fragment of the mitochondrial cytochrome oxidase I gene yielded three major evolutionary lineages, where two were clearly associated with leek and the third with tobacco.

Genetic structure of the invasive pest Bemisia tabaci: evidence of limited but persistent genetic differentiation in glasshouse populations

Article Abstract:

Several studies are conducted to explain the genetic structure of Bemisia tabaci, a complex pest of distinct genetic groups that is kept in the glasshouses. The pest was found to exhibit only limited differentiation, irrespective of the surrounding enclosed environment and extreme isolation.

Invasion success of the bumblebee, Bombus terrestris, despite a drastic genetic bottleneck

Article Abstract:

The results of genetic screening, based on micro satellites of the invading population of Bombus terrestris in Tasmania are presented. The findings show that Bombus terrestris is a highly invasive species capable of establishing itself even after a dramatic genetic bottleneck.
