Gastrulation constitutes a fundamental yet diverse morphogenetic process of metazoan development. Modes of gastrulation range from stochastic translocation of individual cells to coordinated infolding of an epithelial sheet. How such morphogenetic differences are genetically encoded and whether they have provided specific developmental advantages is unclear. Here we identify two genes, folded g...

Bacillus kochii Oregon-R-modENCODE strain BDGP4 was isolated from the gut of Drosophila melanogaster for functional host microbial interaction studies. The complete genome comprised a single chromosomal circle of 4,557,232 bp with a G+C content of 37% and a single plasmid of 137,143 bp.

We investigated developmental time difference in response to dietary restriction (DR) in two sibling species, Drosophila melanogaster and Drosophila simulans, which were collected at the same time from two different localities in Turkey. Different diets used in this experiment were: standard (C), sugar reduced (DR-S), yeast reduced (DR-Y), and sugar with yeast reduced (DR-SY) diets. When the sp...

MicroRNAs (miRNAs) are small non-coding RNAs with important regulatory roles in post-transcriptional regulation of metazoan development, homeostasis and disease. The full set of miRNAs is not known for any species and it is believed that many await discovery. The recent assembly of 15 insect genomes has provided the opportunity to identify novel miRNAs in the fruit fly, Drosophila melanogaster....

Abstract Classical biological control, i.e., the introduction of natural enemies from an invasive pest’s area origin, has been proposed repeatedly to control spotted wing drosophila Drosophila suzukii in Americas and Europe. Results surveys Asia laboratory experiments suggest parasitoid G1 Ganaspis cf. brasiliensis as a suitable agent. To study host specificity under semi-field conditions, we c...

Four genera and 12 species of drosophilid flies have been recorded during our survey in five regions Georgia 2021. Two genera, Amiota (Loew, 1862) Gitona Meigen, 1830, four ( subtusradiata Duda 1934, Drosophila busckii Coquillett 1901, D. kuntzei Duda, 1924, distigma 1830) represent new records for the fauna (Sakartvelo).

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...

Abstract Native to Southeast Asia, the spotted wing drosophila (SWD), Drosophila suzukii Matsumura, rapidly invaded America and Europe in past 20 years. As a crop pest of soft-skinned fruits with wide range host plants, it threatens fruit industry worldwide, causing enormous economic losses. To control this invasive species, an understanding its population dynamics structure is necessary. Here,...

Leucokinins (LKs) constitute a family of neuropeptides identified in numerous insects and many other invertebrates. LKs act on G-protein-coupled receptors that display only distant relations to known receptors. In adult Drosophila, 26 neurons/neurosecretory cells three main types express LK. The four brain interneurons are two types, these implicated several important functions the fly’s behavi...
