Platt2,5, Zannita Fast Horse2, Thomas R. Rainwater3, and Stanlee M. Miller4 ABSTRACT.—From October 2003 through April 2006, we collected 565 fleas incidental to a distribution survey of mammals in southwestern South Dakota. Sixty-one specimens, representing 18 species of mammals, possessed 20 species of fleas. The geographic distributions of these flea species revealed 8 new records for the Black Hills and its adjacent grasslands. Four species—Megarthroglossus divisus, Stenoponia americana, Odontopsyllus dentatus, and Amaradix euphorbi—constitute new records for South Dakota, thus increasing the state’s known flea fauna to 42 species. Hunters, trappers, and field biolo- gists should be aware that serosurveillance during the 1990s revealed the presence of sylvatic plague and tularemia in the Black Hills area. RESUMEN.—Desde octubre de 2003 hasta abril de 2006, colectamos 565 pulgas de manera incidental durante un estudio de la distribución de mamíferos en el suroeste del estado de Dakota del Sur. Los 61 especímenes, que representaban 18 especies de mamíferos, albergaban 20 especies de pulgas. Sus distribuciones geográficas revelaron 8 nuevos registros para las Colinas Negras (Black Hills) y las praderas adyacentes. Cuatro de estas especies (Megarthroglossus divisus, Stenoponia americana, Odontopsyllus dentatus y Amaradix euphorbi) constituyen nuevos registros para Dakota del Sur. Esto aumenta el número de especies de pulgas conocidas del estado a 42 especies. Los cazadores, tramperos y biólogos de campo deben estar conscientes de que la vigilancia serológica durante la década de los 1990 reveló la presencia de la plaga silvática y la tularemia en el área de las Colinas Negras.

ABSTRACT FLEAS, HOSTS AND HABITAT: WHAT CAN WE PREDICT ABOUT THE SPREAD OF VECTOR-BORNE ZOONOTIC DISEASES? MEGAN M. FRIGGENS Vector-borne diseases of humans and wildlife are experiencing resurgence across the globe. I examine the dynamics of flea borne diseases through a comparative analysis of flea literature and analyses of field data collected from three sites in New Mexico: The Sevilleta National Wildlife Refuge, the Sandia Mountains and the Valles Caldera National Preserve (VCNP). My objectives were to use these analyses to better predict and manage for the spread of diseases such as plague (Yersinia pestis). To assess the impact of anthropogenic disturbance on flea communities, I compiled and analyzed data from 63 published empirical studies. Anthropogenic disturbance is associated with conditions conducive to increased transmission of flea-borne diseases. Most measures of flea infestation increased with increasing disturbance or peaked at intermediate levels of disturbance. Future trends of habitat and climate change will probably favor the spread of flea-borne disease.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Fleas (Siphonaptera) are Cretaceous, and Evolved with Theria Qiyun Zhu1, Michael Hastriter2, Michael Whiting2, 3, Katharina Dittmar1, 4* Jan. 23, 2015 Abstract: Fleas (order Siphonaptera) are highly-specialized, diverse blood-feeding ectoparasites of mammals and birds with an enigmatic evolutionary history and obscure origin. We here present a molecular phylogenetic study based on a compre- hensive taxon sampling of 259 flea taxa, representing 16 of the 18 extant families of this order. A Bayesian phylogenetic tree with strong nodal support was recovered, consisting of seven sequentially derived lineages with Macropsyllidae at the base and Stephanocircidae as the second basal group. Divergence times of flea lineages were estimated based on fossil records and host specific associations to bats (Chiroptera), showing that the common ancestor of extant Siphonaptera split from its clos- est mecopteran sister group in the Early Cretaceous and basal lineages diversified during the Late Cretaceous. However, most of the intraordinal divergence into families took place after the K-Pg boundary. Ancestral states of host association and bioge- ographical distribution were reconstructed, suggesting with high likelihood that fleas originated in the southern continents (Gondwana) and migrated from South America to their extant distributions in a relatively short time frame. Theria (placental mammals and marsupials) represent the most likely ancestral host group of extant Siphonaptera, with marsupials occupying a more important role than previously assumed.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

Trait-based and phylogenetic associations between parasites and their hosts: a case study with small mammals and fleas in the Palearctic. – Oikos doi: 10.1111/oik.02178 Appendix 1 Host and flea traits/properties: explanations and data sources Hosts Body mass Body mass is the central characteristic of a species and is commonly employed in developing hypotheses related to physiological and behavioural responses. For example, Peters (1983) presented a large number of allometric relations between various animal characteristics and body mass. From a parasite perspective, host body mass may influence parasite’s abundance (due to the obvious reasons) and host specificity. For example, a host body mass is associated with persistence of a host individual in time merely because a larger host species lives longer and, thus, represents a more predictable resource for a parasite (Peters 1983). As a result, parasite species with higher host specificity are expected to exploit large hosts, whereas small-bodied hosts are expected to be exploited mainly by generalist parasites. Indeed, our earlier findings indicated that the exploitation of large-bodied, and therefore long-lived, host species has likely promoted specialization in fleas (Krasnov et al. 2006a). Data on mean body mass of a host species were obtained from Silva and Downing (1995), Degen (1977) or PanTHERIA database (Jones et al. 2009). Basal metabolic rate Investment of host in a high basal metabolic rate (BMR) could be associated with parasitism as a compensation for a costly immune response when parasite challenges are either strong (e.g., in case of highly abundant parasite) or diverse (in case of attacks by multiple parasites) (Morand and Harvey 2000).

    biomolecules Review Molecular and Genetic Mechanisms That Mediate Transmission of Yersinia pestis by Fleas B. Joseph Hinnebusch *, Clayton O. Jarrett and David M. Bland Laboratory of Bacteriology, Rocky Mountain Laboratories, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Hamilton, MT 59840, USA; [email protected] (C.O.J.); [email protected] (D.M.B.) * Correspondence: [email protected] Abstract: The ability to cause plague in mammals represents only half of the life history of Yersinia pestis. It is also able to colonize and produce a transmissible infection in the digestive tract of the flea, its insect host. Parallel to studies of the molecular mechanisms by which Y. pestis is able to overcome the immune response of its mammalian hosts, disseminate, and produce septicemia, studies of Y. pestis–flea interactions have led to the identification and characterization of important factors that lead to transmission by flea bite. Y. pestis adapts to the unique conditions in the flea gut by altering its metabolic physiology in ways that promote biofilm development, a common strategy by which bacteria cope with a nutrient-limited environment. Biofilm localization to the flea foregut disrupts normal fluid dynamics of blood feeding, resulting in regurgitative transmission. Many of the important genes, regulatory pathways, and molecules required for this process have been identified and are reviewed here.

ALLRED Salt Lake City, Utah In recent years increased interest has been shown toward those arthropods which are capable- and potential' vectors of diseases to man and animals closely associated with man. Although outbreaks of human plague in the United States have never been of such dis- astrous proportions as those in Europe and Asia, there has been con- tinued concern over its presence in sylvatic form since its discovery in rats at San Francisco in 1900. Various workers have implicated more than sixty species and subspecies of fleas with human and syl- vatic plague throughout the world. Of this number, over forty-five species and subspecies are known to occur in the United States as obligate or facultative parasites of birds and mammals.

HUMPHREYS3 Department of Zoology, Ohio University, Athens, Ohio ABSTRACT A check list of Ohio Siphonaptera is presented, with species distribution records listed by city or county. Twenty species and four subspecies are recorded from Ohio. Chaetopsylla lotoris (Stewart), Conorhinopsylla stanfordi Stewart, Doratopsylla blarinae C. Fox, Epitedia wenmanni testor (Rothschild), Stenoponia americana (Baker), Peromyscopsylla scotti I. Fox, and Oropsylla arctomys (Baker) are new state distribution records. Early studies of fleas in Ohio are few. Fox (1940), in his comprehensive study, Fleas of the Eastern United States, listed 8 species from Ohio. Hughes, in an unpublished report (dated 1938), records 5 species. These records, plus occasional records from other authors, provide a list of 12 species of fleas from the state. During this study, six hundred and five Siphonaptera from 20 species of mam- mals and 1 bird were examined. Four hundred and thirty-three specimens were collected by the author from mammals live-trapped during the period of March through December, 1964. The remaining specimens were either contributed by various individuals (60 specimens) or are in the entomological collections at The Ohio State University (110) or Ohio University (2). These specimens together with literature records on North American fleas provide a total of 20 species and 4 subspecies from Ohio. Seven species are reported for the first time from the state. An expression of thanks is extended to Dr. W. C. Stehr, Ohio University, for his encouragement and suggestions during the study, to Dr. A. H. Benton, State University College, Fredonia, New York, for verification of some of the author's identifications, to Dr.
