The Hawaiian Drosophilidae contains approximately 1000 species, placed in species groups and subgroups based largely on secondary sexual modifications to wings, forelegs and mouthparts. Members of the spoon tarsus subgroup possess a cup-shaped structure on the foretarsi of males. Eight of the twelve species in this subgroup are found only on the Big Island of Hawaii, suggesting that they have d...
The immigrans species group in the Drosophilinae is one of the representative species groups of Drosophila in East Asia. Although this group constitutes a significant part of the drosophilid fauna in the Old World, only a few species have been analyzed in previous molecular phylogenetic studies. To study the phylogeny of the immigrans group, we analyzed the nucleotide sequences of two nuclear g...
BACKGROUND A mixture of wine and vinegar is more attractive than wine or vinegar to spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), and ethanol and acetic acid are considered key to that attractiveness. In addition to ethanol and acetic acid, 13 other wine and vinegar volatiles are antennally active to D. suzukii and might be involved in food finding. RESULTS...
Drosophila suzukii Matsumara, also referred to as the spotted wing drosophila, has recently expanded its global range with significant consequences for its primary host crops: blueberries, blackberries, raspberries, cherries, and strawberries. D. suzukii populations can increase quickly, and their infestation is difficult to predict and prevent. The development of effective tools to detect D. s...
Drosophila obscura is a common fruit fly that inhabits the temperate forests of Europe. While it abundant in north compared to other Drosophila, its density decreases southwards, where gradually replaced by species. This study describes variation mitochondrial Cyt b gene D. from several European populations. We observed large number haplotypes, together with structuring genetic variation. Genet...
