Preface Every four years, dipterists from around the globe meet up at the International Congresses of Dipterology to discuss scientific progress in the various disci- plines of dipterology, present research findings, liaise with colleagues and forge future research collaborations. The 9th International Congress of Dipterology (ICD9) is the first such Congress to be held on the African continent and the first in a developing country. The overall theme of the Congress was “Afrotropical dipterology”, but all themes and regions were represented. A total of 273 full delegates and students from 51 countries, attended the Congress, including 61 delegates from 13 African countries. This volume contains 321 abstracts of oral and poster presentations submitted to the Organising Committee of ICD9 for the Congress held in Windhoek, Na- mibia, in November 2018. This collection of abstracts serves as a snapshot of the range and quality of scientific activity in the international dipterological com- munity and this publication is a permanent record, summarising presentations at the Congress, serving an important purpose both for those who attended the meeting and those who did not. The table of contents is arranged according to the 23 symposia, arranged al- phabetically, to facilitate location of abstracts in specific topic areas. For the purposes of ICD9, poster presentations do not form part of symposia and are listed separately. Abstracts in the volume are arranged alphabetically by first author and the names of presenting authors (if more than one) are underlined. The footer for each abstract indicates to which symposium an oral presentation belongs or whether a plenary, keynote or poster presentation. Two indexes are included at the back of the volume, one comprising the names of all abstract authors, the other key words (as provided by the authors) and used in the titles. Abstracts were edited to a certain extent for consistency of style and formatting in collaboration with the authors and the various symposia Convenors, but the content of abstracts remains the sole responsibility of the authors. Spelling of words follows British rather than American orthography and all abstracts are edited to apply the passive voice. Presenting author names are underlined and an asterisk (*) indicates corresponding author. We take this opportunity to thank all ICD9 delegates and symposium Conve- nors, who assisted with arrangements and made the Congress possible. We also thank the various sponsors who gave financial support (as indicated on the back cover of this book), the Government of the Republic of Namibia and the people of Namibia for their friendly and helpful support.

  • Diptera: Bombyliidae and Syrphidae) Floral Foraging Fidelity in Subalpine Meadows
    Effects of Floral Diversity and Density on Fly (Diptera: Bombyliidae and Syrphidae) Floral Foraging Fidelity in Subalpine Meadows Student: Nelson Vila-Santana Mentor: Berry Brosi and Heather Briggs Advanced Independent Research Summer 2012 Abstract: Foraging behavior of pollinators is an extensively researched topic. Research on bee, butterfly, and hummingbird foraging behavior has led to a greater understanding of the impacts of plant community composition on foraging behavior. This research has been further enhanced by fly foraging behavior and its importance in ecosystems. In order to determine the relationship flies have with the plant community we are examining the effects of flower species diversity and conspecific floral density on fly (Diptera: Syrphidae and Bombyliidae) foraging fidelity. Fly foraging fidelity was seen to be effected by both of these floral community characteristics. It was observed that as flower species diversity increased we saw a decrease in foraging fidelity. Also as conspecific floral density increased we observed an increase in foraging fidelity. Future topics of interest may involve the impact of these effects, conspecific floral densities and floral species diversity, on plant fitness along with other variables which may impact fly foraging fidelity. Introduction: Extensive research on bee, butterfly, and hummingbird foraging behavior has lead to a greater understanding of the importance of foragers as pollinators and plant community impacts on this foraging. Fly foraging research, however limited, has begun to identify the importance of flies as pollinators (Kearns 2001) With more research we may be able to better understand the importance of Dipteran pollinators. (Kearns 2001). As noted in Kearns et al.

Junto al nombre de la especie se relacionan sus sinónimos y las localidades donde fueron citadas. También se hace una aproximación a su distribución paleártica y peninsular. Previamente a la lista de especies se realiza una pequeña introducción. A pesar de que la Familia Bombyliidae es una de las más nu- merosas y diversas del orden Dipte- ra, al mismo tiempo es una de las más desconocidas de la entomofau- na en general. Se han descrito unas 4500 especies en todo el mundo, y de ellas 200 aproximadamente se han citado en la península Ibérica. Su distribución es cosmopolita, a excepción de los polos, y aunque A la izquierda Bombylius sticticus (Homeophthalmae) con el cuerpo cubierto por una densa son más abundantes en regiones pilosidad de color negro, excepto por los pelos blancos del tórax; a la derecha, áridas y semiáridas también están Hemipenthes morio (Tomophthalmae) en el que la pilosidad es escasa y por el contrario presentes, aunque en menor medi- abundan las escamas.

  • Introduction
    PDF file from Evenhuis, N.L. & D.J. Greathead, 1999, World Catalog of Bee Flies (Diptera: Bombyliidae). Backhuys Publishers, Leiden. xlviii + ix 756 pp. INTRODUCTION Bombyliids, or bee flies as they are commonly called, comprise a diverse and speciose assemblage of brachycerous flies. With more than 4,500 species known worldwide, they are one of the largest families of Diptera, surpassed in numbers of species only by the Tipulidae (14,000), Tachinidae (9,200), Syrphidae (5,800), Asilidae (5,600), Ceratopogonidae (5,300), and Dolichopodidae (5,100). They occur in a variety of habitats and ecosystems (from ca. 10 km from the Arctic Ocean in Canada through all latitudes as far south as Tierra del Fuego; and at altitudes from over 3500 m in the Himalayas to 200 m below sea level at the shores of the Dead Sea). They are found on all continents except Antarctica and also many oceanic islands. The family has a remarkable range in size (from some Exoprosopa with wingspans of more than 60 mm to the tiny Apolysis that can be as small as 1.5 mm in length) and variety of shapes (e.g., Systropus mimicking ammophiline wasps; Bombomyia mimic- king bumblebees). The adults of the larger species are powerful and agile fliers, rivaling the syrphid flies in their ability to hover and move in all directions while in flight. With many species possessing colorful patterns of stripes and spots on the wings and bodies, bee flies are often some of the most striking in appearance of all the Diptera. Individuals can often be seen either resting in the open on trails or on rocks or twigs sunning themselves, or feeding on a variety of flowering plants.

St::ttns of 15 Antioch Insects Listed in Notice of 75 Review by the U.S. Fish "l.nd Wildlife Service INTRODUCTION The sand dune formation east of Antioch, Contra Costa County, California, comprised the largest riverine dune system in California. Biogeographically, this formation was unique because it supported a northern extension of plants and animals of desert, rather than coastal, affinities. Geologists believe that the dunes were relicts of the most recent glaciation of the Sierra Nevada, probably originating 10,000 to 25,000 years ago, with the sand derived from the supratidal floodplain of the combined Sacramento and San Joaquin Rivers. The ice age climate in the area is thought to have been cold but arid. Presumably summertime winds sweeping through the Carquinez Strait across the glacial-age floodplains would have picked up the fine-grained sand and redeposited it to the east and southeast, thus creating the dune fields of eastern Contra Costa County.

  • Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
    EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied.

Development of trapping systems is an evolving process that results in improved agriculture. Trapping systems require a holistic approach that encompasses endemic and invasive species, human needs, as well as economic pressures. The purpose of this working document is to provide a mechanism for an evolving process that allows providing NPPO’s, RPPO’s, action agencies, industry, and scientists a framework to fully utilize current and future trapping technologies. The dedication of the authors in developing this manual is based on a commitment to provide an updated and coherent use of technologies available for trapping fruit flies. Every effort was made to ensure that this document is accurate, however, the activities associated with the trapping of fruit flies makes this a complex and dynamic process.
