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

    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.

Many are highly beneficial. Almost all U.S. crops and domesticated animals, many sport fish and aquiculture species, numerous horticultural plants, and most biologicalN control organisms have origins outside the country. A large number of NIS, however, cause significant economic, environmental, and health damage. These harmful species are the focus of this study. The total number of harmful NIS and their cumulative impacts are creating a growing burden for the country. We cannot completely stop the tide of new harmful introductions. Perfect screening, detection, and control are technically impossible and will remain so for the foreseeable future. Nevertheless, the Federal and State policies designed to protect us from the worst species are not safeguarding our national interests in important areas. These conclusions have a number of policy implications. First, the Nation has no real national policy on harmful introductions; the current system is piecemeal, lacking adequate rigor and comprehensiveness. Second, many Federal and State statutes, regulations, and programs are not keeping pace with new and spreading non-indigenous pests.

Larvae, pupae, pupal exuviae, and nymphs of insects were obtained from samples collected by a plankton net monthly during a 1-year period in 2008 and 2009 at seven different sites of the Dicle (Tigris) River Basin. A total of 35 taxa from the orders Trichoptera (1 taxon), Ephemeroptera (3 taxa), and Diptera (31 taxa) were identified. Chironomidae (Diptera) was the most diverse group and was represented by three major subfamilies, namely Tanypodinae (2 taxa), Orthocladiinae (19 taxa), and Chironominae (7 taxa). Among these species, Nanocladius (Nanocladius) spiniplenus Saether, 1977 is a new record for Turkey as well as for western Asia. In addition, the Psychomyia larvae found for the first time in the Dicle (Tigris) River Basin (Turkey) were described. Both taxa have been illustrated to warrant validation. Taxa number varied spatially from 6 to 14 and temporally from 2 to 12 during the sampling period. Along the river, Cricotopus bicinctus and Orthocladius (S.) holsatus were the most common taxa. Key words: Diptera, Ephemeroptera, Trichoptera, Insecta, Dicle (Tigris) River 1.

The former breeds primarily on prickly pears (genus Opuntia) whereas the latter breeds on columnar cacti of the genera Cereus and Trichocereus, although with certain degree of niche overlapping. We examined the interspecific differences in diurnal temporal patterns of adult emergence from puparia and evaluated whether this behavior is affected by rearing in the different cactus hosts available in nature. We detected important host-dependent genetic variation for this trait differentially affecting the emergence schedule of these species. Diurnal pattern of emergence time was directly correlated with developmental time and negatively correlated with adult wing size, suggesting that early emergences are at least indirectly correlated with increased fitness.

Ratcliffe3 Abstract Color and volatile stimulus preferences of Drosophila repleta (Patterson) Diptera: Drosophilidae), a nuisance pest of swine and poultry facilities, were tested using sticky card and bottle traps. Attractions to red, yellow, blue, orange, green, purple, black, grey and a white-on-black contrast treatment were tested in the laboratory. Drosophila repleta preferred red over yellow and white but not over blue. Other than showing preferences over the white con- trol, D. repleta was not observed to have preferences between other colors and shade combinations. Pinot Noir red wine, apple cider vinegar, and wet swine feed were used in volatile preference field trials. Red wine was more attractiveD. to repleta than the other volatiles tested, but there were no dif- ferences in response to combinations of a red wine volatile lure and various colors. Odor was found to play the primary role in attracting D. repleta.

It was recently found from the Maoershan National Nature Reserve, Guangxi, China. The characteristics of the new species are based not only on morphological characters but also on DNA sequences of the mitochondrial COII (cytochrome c oxidase subunit II) gene. Key words Genetic distance, morphology, Old World, Oriental Region, Sophophora. 1 Introduction The Drosophila obscura species group is one of the major lineages within the well-known sophophoran radiation recognized by Throckmorton (1975). Studies on the taxonomy, geography, chromosomal evolution, reproductive-isolation, protein polymorphism and phylogeny of this group have greatly promoted the early development of evolutionary genetics (Lakovaara & Saura, 1982). A majority of the currently known species of this group (44 in total) was recorded from the Holarctic temperate zone, with the remainder recorded from varied sites in South America (Lakovaara & Saura, 1982; Head & O’Grady, 2000), as well the Afrotropical (Séguy, 1938; Tsacas et al., 1985) and Oriental Regions (Watabe et al., 1996; Watabe & Sperlich, 1997; Gao et al., 2003, 2009; Table 1). In this paper, we describe a new species of the obscura group found from our recent field survey in Guangxi, China. The definition of the new species is based on morphological characters and DNA sequences of the mitochondrial COII (cytochrome c oxidase subunit II) gene.
