The Male Terminalia of Seven American Species of Drosophila
Alpine Entomology 1 2017, 17–31 | DOI 10.3897/alpento.1.20669 The male terminalia of seven American species of Drosophila (Diptera, Drosophilidae) Carlos Ribeiro Vilela1 1 Departamento de Genética e Biologia Evolutiva, Instituto de Biociências, Universidade de São Paulo, Rua do Matão 277, Cidade Universitária “Armando de Salles Oliveira”, São Paulo - SP, 05508-090, Brazil http://zoobank.org/197D5E09-957B-4804-BF78-23F853C68B0A Corresponding author: Carlos Ribeiro Vilela ([email protected]) Abstract Received 28 August 2017 The male terminalia of seven species of Drosophila endemic to the New World are de- Accepted 28 September 2017 scribed or redescribed and illustrated: one in the hydei subgroup (D. guayllabambae) and Published 20 November 2017 four in the mulleri subgroup (D. arizonae, D. navojoa, D. nigrodumosa, and D. sonorae) of the repleta group; one in the sticta group (D. sticta) and one so far unassigned to group Academic editor: (D. comosa). The D. guayllabambae terminalia redescription is based on a wild-caught Patrick Rohner fly. The redescriptions of the terminalia of the four species in the mulleri subgroup are based on strain specimens, while those of D. sticta and D. comosa terminalia are based Key Words on their holotypes. D. guayllabambae seems to be a strictly mountainous species of the Ecuadorian and Peruvian Andes. D. nigrodumosa is apparently endemic to Venezuela, oc- Drosophila subgenus curring in the Andes as well as at lower altitudes. The remaining five occurs only at lower Drosophilinae altitudes of the American continent. The detailed line drawings depicted in this paper aim line drawings to help interested taxonomists to tell those species apart. -
Comparison of Baits for Monitoring the Spotted Wing Drosophila, Drosophila Suzukii
AN ABSTRACT OF THE THESIS OF Joseph R. Kleiber for the degree of Master of Science in Horticulture presented on June 6, 2013 Title: Comparison of Baits for Monitoring the Spotted Wing Drosophila, Drosophila suzukii Abstract approved: Denny J. Bruck Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe fruit. The female SWD has a serrated ovipositor that allows her to lay eggs under the skin of a wide range of fruits, where the eggs hatch into larvae and they consume the inside of the fruit. This feeding results in fruit collapse and deterioration, and the hole created by the oviposition puncture allows for secondary infection by microorganisms, yield losses, reduced fruit quality and degrades. The current control is to apply an insecticide treatment when the fruit begins to color and continue to keep the crop protected with chemical treatments until harvest is complete. The current monitoring tools are not sensitive enough to attract SWD at the critical time to establish economic thresholds, appropriately time treatments and allow growers to make good management decisions. The objective of this research project was to determine if a more sensitive attractant than the currently standard 5% acidity apple cider vinegar traps could be defined. A number of food products and commercially available lures were tested in greenhouse and field experiments for their attractiveness to D. -

Advances in Genetics, Development, and Evolution of Drosophila
springer.com Seppo Lakovaara (Hrsg.) Advances in Genetics, Development, and Evolution of Drosophila In 1906 Castle, Carpenter, Clarke, Mast, and Barrows published a paper entitled "The effects of inbreeding, cross-breeding, and selection upon the fertility and variability of Drosophila." This article, 55 pages long and published in the Proceedings of the Amer• ican Academy, described experiments performed with Drosophila ampe• lophila Lov, "a small dipterous insect known under various popular names such as the little fruit fly, pomace fly, vinegar fly, wine fly, and pickled fruit fly." This study, which was begun in 1901 and published in 1906, was the first published experimental study using Drosophila, subsequently known as Drosophila melanogaster Meigen. Of course, Drosophila was known before the experiments of Cas• tles's group. The small flies swarming around grapes and wine pots have surely been known as long Softcover reprint of the original 1st ed. as wine has been produced. The honor of what was the first known misclassification of the 1982, X, 474 p. fruit flies goes to Fabricius who named them Musca funebris in 1787. It was the Swedish dipterist, C.F. Fallen, who in 1823 changed the name of ~ funebris to Drosophila funebris Gedrucktes Buch which was heralding the beginning of the genus Drosophila. Present-day Drosophila research Softcover was started just 80 years ago and first published only 75 years ago.

Acoustic Duetting in Drosophila Virilis Relies on the Integration of Auditory and Tactile Signals Kelly M Larue1,2, Jan Clemens1,2, Gordon J Berman3, Mala Murthy1,2*
RESEARCH ARTICLE elifesciences.org Acoustic duetting in Drosophila virilis relies on the integration of auditory and tactile signals Kelly M LaRue1,2, Jan Clemens1,2, Gordon J Berman3, Mala Murthy1,2* 1Princeton Neuroscience Institute, Princeton University, Princeton, United States; 2Department of Molecular Biology, Princeton University, Princeton, United States; 3Lewis Sigler Institute for Integrative Genomics, Princeton University, Princeton, United States Abstract Many animal species, including insects, are capable of acoustic duetting, a complex social behavior in which males and females tightly control the rate and timing of their courtship song syllables relative to each other. The mechanisms underlying duetting remain largely unknown across model systems. Most studies of duetting focus exclusively on acoustic interactions, but the use of multisensory cues should aid in coordinating behavior between individuals. To test this hypothesis, we develop Drosophila virilis as a new model for studies of duetting. By combining sensory manipulations, quantitative behavioral assays, and statistical modeling, we show that virilis females combine precisely timed auditory and tactile cues to drive song production and duetting. Tactile cues delivered to the abdomen and genitalia play the larger role in females, as even headless females continue to coordinate song production with courting males. These data, therefore, reveal a novel, non-acoustic, mechanism for acoustic duetting. Finally, our results indicate that female-duetting circuits are not sexually differentiated, as males can also produce ‘female-like’ duets in a context- dependent manner.

No reuse allowed without permission. 25 Abstract 26 In animals, PIWI-interacting RNAs (piRNAs) silence transposable elements (TEs), 27 protecting the germline from genomic instability and mutation. piRNAs have been 28 detected in the soma in a few animals, but these are believed to be specific 29 adaptations of individual species. Here, we report that somatic piRNAs were likely 30 present in the ancestral arthropod more than 500 million years ago. Analysis of 20 31 species across the arthropod phylum suggests that somatic piRNAs targeting TEs 32 and mRNAs are common among arthropods. -
Hypothesis As an Alternative. the Distribution Of
Heredity (1976), 36 (3), 293-304 REASSOCIATIONPATTERNS AMONG SEGMENTAL INTERCHANGES IN MAIZE D.B. WALDEN and R. C. JANCEY Department of Plant Sciences,Universityof WesternOntario,London, Ontario N6A 3K7 Received2.iv.75 SUMMARY Data from Longley (1961) and Burnham (1969) on the cytological position of the break-points in chrornosomal rearrangements in maize were re-expressed in terms of segment lengths and analysed. After correction for the deviation of the distribution of break-points from an equidistribution, it was shown that highly significant excesses and deficits occurred among some but not all segment length classes. It was concluded that the pattern of reassociation shows: (i) that reassociation involves non-homologues whose interstitial segments are of similar length more frequently than expected; (ii) that the two interchange segments involved in a translocation are of similar length more frequently than expected. 1. INTRODUCTION AN extensive literature exists on the genetic effects and consequences of exposure to radiation and radiomimetic and radiochemical compounds. The origin of chromosomal aberrations had long been considered to be the consequence of" breakage and reunion" until Revell (1955) proposed an "exchange" hypothesis as an alternative. The distribution of the "breakage" or "exchange" events has been approximately determined in several species, with a" random "distribution being claimed by some workers and a "non-random" distribution favoured by several recent investigators (e.g. Caspersson et al., 1972). It is important for the present communication to note that most of the studies record observations made one or a few cell generations after exposure to the mutagen and that only limited information is available about the survival of the aberrations so induced. -

Abstract I used Drosophila melanogaster as a model to study the role of the gut microbiota, specifically yeasts, in animal physiology. I used Saccharomyces cerevisiae, the yeast commonly included in Drosophila diet, and Lachancea kluyveri, isolated from some Drosophila in the wild, and generated axenic (germ-free) and gnotobiotic (yeast-fed) flies. I found that L. kluyveri persists in the crop, as ascospores and vegetative cells, longer than S. cerevisiae. Some L. kluyveri vegetative cells survive passage through the gut. Egg to adult development time is reduced by 14% in vials containing live L. kluyveri or S. cerevisiae, whereas heat-killed yeasts reduced development time by 3.5-4.5%. -
