Genetics Research (92)1 2010
Abstract
We estimate a phylogeny for 176 drosophilid (12 genera) and four non-drosophilid species, using gene sequences for up to 13 different genes per species (average: 4333 bp, five genes per species). This is the most extensive set of molecular data on drosophilids yet analysed. Phylogenetic analyses wer...

Abstract
A number of flies around the eyes of a person or around a fruit bait were collected from Huangshan Mountain, and experimentally infected by newborn larvae of Thelazia callipaeda. After 20 days, the flies were examined for T. callipaeda. Following dissection, 3 (30%, 3/10) of Amiota magna, and 55 (21...

Abstract
The genus Rhinoleucophenga Hendel comprises 18 nominal species and has a Neotropical and Nearctic distribution. A new species was found in a collection in Florianópolis, SC, Brazil, and is described as Rhinoleucophenga joaquina sp. nov. The specimens found were reared from flowers of Dyckia encholi...

Abstract
The phenotypic plasticity of wing size and wing shape of Zaprionus indianus was investigated in relation to growth temperature (17 degrees C to 31 degrees C) in two natural populations living under different climates, equatorial and subtropical. The two populations were clearly distinguished not onl...

Abstract
Flies in the genus Drosophila have been the dominant model organisms in genetics for over a century and, with a dozen complete sequences now available, continue as such in modern comparative genomics. Surprisingly, estimates of genome size for this genus have been relatively sparse, covering less th...

We demonstrate that Fuca is expressed in male and female germ lines. RT-PCR analysis indicated a broader tissue expression. Homologous genes are expressed in the same tissues in several drosophilid flies belonging to the genera Drosophila and Scaptodrosophila. However, the long transcript is restric...

Abstract
The subfamily Steganinae (Diptera, Drosophilidae) includes flies which display zoophilic feeding behaviour in the larval and/or adult stages, some of which act as vectors of Spirurida eyeworms, which infect both carnivores and humans. To date, the taxonomy and phylogeny of the subfamily Steganinae h...

Abstract
The sciarid DNA puff C4 BhC4-1 gene is amplified and transcribed in salivary glands at the end of the larval stage. In transgenic Drosophila, the BhC4-1 promoter drives transcription in prepupal salivary glands and in the ring gland of late embryos. A bioinformatics analysis has identified 162 seque...

Abstract
We show that testicular architecture is much more variable (both within and between species) than is generally appreciated. Moreover, the number of first spermatocytes is strongly correlated to the sperm length, which is inversely related to the sperm production, and thus the workload of the testis....

Abstract
Mesosternal (MS) bristles in Drosophila are a pair of machrochaetae found at the sternal end of the sternopleural (STP) microchaetae, and are thought to be invariable. In a closely related drosophilid genus, Zaprionus, their number is four and, in contrast to Drosophila, they show interspecific and...
