Disease transmission relies heavily on odour- mediated behaviours, including e.g., sugar- and host-seeking, which are crucial during the mosquito life cycle and has dire impacts on vectorial capacity. Olfaction is, one of the most sophisticated sensory systems, and is the sense by which insects locate and discriminate biologically-relevant odorant volatiles. In female mosquitoes, host-seeking is generally not observed before 2-3 days following adult emergence. Of note, males have also been shown to respond to and orient towards host-associated cues. Vector-borne pathogens can alter the behaviour and physiology of their host, consequently increasing the risk of disease transmission. Thus, the modulation of host-seeking depends on multiple factors, including e.g., age, sex, and infection by a pathogen, which is the main focus of this thesis. During my PhD, I have shown that the modulation of the onset of host-seeking coincides with changes in transcript abundance of chemosensory-related genes expressed in the antennae of newly-emerged mosquitoes. Of these genes, one particular odorant receptor, OR117, exhibits a decrease in transcript abundance as female mosquitoes become capable of host-seeking. Later, I have functionally characterised OR117, together with another odorant receptor-of-interest, OR103, which has previously been shown to be more abundant in the human-preferring subspecies of Ae. aegypti. Both OR117 and OR03 are tuned to monoterpenes, and their potential role in the transition between sugar- to host-seeking and human avoidance, respectively, is discussed. Furthermore, I have demonstrated that the locomotion and host-seeking is modulated in dengue-infected females in a time-dependent manner, i.e. depending on the time post-infection, and coincides with changes in transcript abundance of genes involved in neural signalling pathways. A better understanding of the modulation of odour-mediated behaviours in mosquitoes is crucial for the development of efficient control strategies against disease vector control.

Eggs are laid in layers on a vertical surface, such as overhanging foliage, projecting rocks, sticks, and aquatic vegetation. Aquatic vegetation is preferred. A shiny or chalky secre- tion, which aids in water protection, often covers eggs. The vertical surfaces on which the eggs are deposited are always directly over water and wet ground favorable to the development of larvae. The female will not deposit egg masses on vegetation that is too dense.

  • ABSTRACT BAYLESS, KEITH MOHR. Phylogenomic Studies of Evolutionary Radiations of Diptera
    ABSTRACT BAYLESS, KEITH MOHR. Phylogenomic Studies of Evolutionary Radiations of Diptera. (Under the direction of Dr. Brian M. Wiegmann.) Efforts to understand the evolutionary history of flies have been obstructed by the lack of resolution in major radiations. Diptera is a highly diverse branch on the tree of life, but this diversity accrued at an uneven pace. Some of radiations that contributed disproportionately to species diversity occurred contemporaneously, and understanding the relationships of these taxa can illuminate broad scale patterns. Relationships between some subordinate groups of taxa are notoriously difficult to untangle, and genomic data will address these problems at a new scale. This project will focus on two major radiations in Diptera: Tabanus horse flies and relatives, and acalyptrate Schizophora. Tabanus includes over one thousand species. Synthesis focused research on the group is stymied by its species richness, worldwide distribution, inconsistent diagnosis, and scale of undescribed diversity. Furthermore, the genus may be non-monophyletic with respect to more than 10 other lineages of horse flies. A groundwork phylogenetic study of worldwide Tabanus is needed to understand the evolution of this lineage and to make comprehensive taxonomic projects manageable. Data to address this question was collected from two different sources. A dataset including five genes was sequenced from ninety-four species in the Tabanus group, including nearly all genera of Tabanini and at least one species from every biogeographic region. Then a new data source from a next generation sequencing approach, Anchored Hybrid Enrichment exome capture, was used to accumulate a dataset including hundreds of genes for a subset of the taxa.

  • Distribution Pattern of Diachlorini S. Str. (Diptera: Tabanidae)1
    MUZEUM I INSTYTUT ZOOLOGII POLSKIEJ AKADEMII NAUK FRAGMENTA FAUNISTICA Fragm. faun. Warszawa, 14.07.1997 4 0 6 59-71 Przemysław Trojan Distribution pattern of Diachlorini s. str. (Diptera: Tabanidae)1 Abstract. Diachlorini s. str. have a disjunctive distribution in the world, their occurrence being limited to 4 centres: American, Mediterranean, South African and Oriental-Australian. Speciation and dispersal centres are only found in tropical areas in South America and New Guinea. Diachlorini s. str. do not occur on the Asian continent, except for the Indian Peninsula (belonging to the Oriental Region) and a small stretch of the eastern coast of the Caspian Sea (belonging to the Mediterranean region). Relationships between the taxa of individual regions are discussed. Key words: Diptera. Tabanidae. Diachlorini, distribution, relationships, world. Author’s address: Muzeum i Instytut Zoologii PAN, ul. Wilcza 64, 00-679 Warszawa, POLAND INTRODUCTION A new division of the subfamily Tabaninae into tribes (TROJAN 1994, 1997) has made it possible to study the distribution pattern of Diachlorini s. str. and Lepidoselagini independently. Up till now interpretations of the distribution have been based on combined data on the occurrence of both these taxa (Mackerras 1954). At present, however, this approach cannot be utilised in either zoogeographical or evolution-related analyses. In my paper on the distribution of Lepidoselagini in the Northern Hemisphere (Trojan 1996) I have demonstrated that, contrary to earlier assumptions, this tribe does not have a Gondwanan distribution. There are numerous representatives of plesiomorphic Lepidoselagini in the Holarctic and their distribution suggests that the area of Laurasia was once inhabited by diverse forms belonging to this tribe.

SYNONYMICAL NOTES ON NEOTROPICAL FLIES OF THE FAMILY TABANIDAE (DIPTERA)^ By G. B. FAIRCHILD Gorgas Memorial Laboratory, Panama The nomenclature of the Neotropical flies of the family Tabanidae has long been in a state of great confusion, in spite of the efforts of a number of students to bring it into some sort of order. The main dif- ficulties seem to have been the lack of adequate collections in any one place and the very numerous inadequate descriptions by several of the older authors. The existing catalogs of Kertesz (1900, 1908) and Surcouf (1921) for the Tabanidae of the World are quite uncritical and are chiefly lists of names. The catalog of the Neotropical Tabani- dae prepared by Krober (1934) was a great step forward, but subse- quent work has modified greatly the understanding of generic and higher categories, and he failed in many cases to appreciate the value of a study of the type specimens of the older descriptions. His cata- log, therefore, although extremely useful, has often proved unreliable. During the fall of 1953 I was enabled, through the aid of a generous travel grant from the Marsh Fund of the National Academy of Sci- ences, to visit the British Museum in London and the Museum d'Histoire Naturelle in Paris.

The distribution parameters of spe‐ cies according to classification by biogeographical regions are used. An appendix indicating the main studies about tabanids according to the countries of their origin is still offered. Keywords: insect vector, horsefly, Neotropical region, taxonomy, bionomy 1. Introduction The species of family Tabanidae Latreille, 1802, commonly known in South America as “­mutucas,” “botucas,” “mbutú,” “colihuacho,” and “moscas de los caballos”, comprises more than 4400 worldwide species, absent only in the regions of higher altitudes and eternal snows [1, 2], with more than 1800 species present in the Neotropics [3]. They are the largest bloodsucking Diptera, reaching up to 25 mm, with a robust body and some with well‐developed proboscis, an aspect that causes respect and fear. Females often require blood meal for maturation of eggs, at least after the first posture, so they are considered autogenous, partially autogenous, or nonautogenous [4]. Males are phytophagous, but females, always in search of blood, repeatedly attack humans, domestic and wild animals, among primates, rodents, alligators, snakes, turtles, and birds, espe‐ cially during the drier seasons [5–8]. Tabanids are known worldwide for its painful sting and are mechanical and biological vectors of several helminths, viruses, bacteria, and protozoa, etio‐ logic agents of diseases that can affect humans and wild and domestic animals 9[ –11].
