Allergen Homologs In The Euroglyphus Maynei Draft Genome, S. Dean Rider, Majorie S. Morgan, Larry G. Arlian
Allergen Homologs In The Euroglyphus Maynei Draft Genome, S. Dean Rider, Majorie S. Morgan, Larry G. Arlian
Biological Sciences Faculty Publications
Euroglyphus maynei is a house dust mite commonly found in homes worldwide and is the source of allergens that sensitize and induce allergic reactions in humans. It is the source of species-specific allergens as well as allergens that are cross-reactive with the allergens from house dust mites Dermatophagoides farinae and D. pteronyssinus, and the ectoparasitic scabies mite Sarcoptes scabiei. The genomics, proteomics and molecular biology of E. maynei and its allergens have not been as extensively investigated as those of D. farinae, D. pteronyssinus, and S. scabiei where natural and recombinant allergens from these species have been characterized. Until now, …
A New Tachinid Genus And Species Record For North America: Iceliopsis Borgmeieri Guimarães, John O. Stireman Iii, Jane E. Dell
A New Tachinid Genus And Species Record For North America: Iceliopsis Borgmeieri Guimarães, John O. Stireman Iii, Jane E. Dell
Biological Sciences Faculty Publications
The Iceliini are a small, enigmatic New World tribe of Tachininae consisting of three genera, Icelia RobineauDesvoidy, Iceliopsis Guimarães, and Erviopsis Townsend, and five recognized species (Guimarães 1976). All known species are exclusively Neotropical in distribution with the exception of Icelia triquetra (Olivier), which ranges from Brazil, through Central America, and as far north as New York state (O’Hara & Wood 2004). Members of the tribe are generally medium-sized (ca. 7–12 mm), elongate, yellowish or grayish in color, and resemble Dexiini or Leskiini in general appearance. Species of Iceliini are relatively rarely collected and there is but a single host …
Evidence For Use Of Alliaria Petiolata In North America By The European Cabbage White Butterfly, Pieris Rapae, Sam L. Davis, Don Cipollini
Evidence For Use Of Alliaria Petiolata In North America By The European Cabbage White Butterfly, Pieris Rapae, Sam L. Davis, Don Cipollini
Biological Sciences Faculty Publications
Pieris rapae L., an invasive crop pest, may have recently begun using Alliaria petiolata Bieb. (Cavara & Grande), a European invasive biennial. We investigated how P. rapae uses forest habitats for nectar and oviposition and examined larval performance on A. petiolata in the field and laboratory. Being known primarily to occupy open habitats, we found that P. rapae regularly uses forest edge habitats, most surveyed A. petiolata plants had P. rapae damage, and P. rapae successfully used both stages of A. petiolata for larval development.

As readers of this newsletter are likely familiar, we and our collaborators have been working for the past several years on a family-wide phylogeny of the Tachinidae of the world (see Stireman et al. 2013, Winkler et al. 2014). We have already published a morphological analysis of tachinid phylogenetics (Cerretti et al. 2014), as well as an initial molecular phylogenetic framework for the family (Winkler et al. 2015). An in-depth molecular phylogenetic analysis of the Phasiinae led by Jeremy Blaschke (originally at University of Tennessee and now at Union University, TN) and Kevin Moulton (U. of Tenn.) is currently being …

California’s central coast differs from many agricultural areas in the U.S., which feature large tracts of monoculture production fields and relatively simple landscapes. Known as the nation’s salad bowl, and producing up to 90% of U.S. production of lettuces, broccoli and Brussels sprouts, this region is a mosaic of fresh vegetable fields, coastal meadow, chaparral shrubs, riparian and woodland habitat. We tested for relationships between the percent cover of crops, riparian and other natural landscape vegetation and the species richness of parasitic wasps and flies foraging in crops, such as broccoli, kale and cauliflower, and interpreted our results with respect …

Readers of this newsletter are likely familiar with our ongoing project to establish a framework phylogeny of world Tachinidae (see articles in The Tachinid Times 26 and 27). This collaborative project, involving myself, Jim O’Hara, Kevin Moulton, Pierfilippo Cerretti, Isaac Winkler and a long list of collaborating tachinidophiles was initiated in 2012 with funding from the U.S. National Science Foundation. Our goal is to produce a robust phylogenetic framework of Tachinidae that can be used to inform tachinid taxonomy, systematics research, and the patterns of tachinid evolution. In previous issues of The Tachinid Times we summarized our progress to date …

The New World tropics represents the most diverse region for tachinid parasitoids (Diptera: Tachinidae), but it also contains the most narrowly defined, and possibly the most confusing, tachinid genera of any biogeographic region. This over-splitting of genera and taxonomic confusion has limited progress toward our understanding the family in this region and much work is needed to revise, redefine, and make sense of the profusion of finely split taxa. In a recent analysis of the Neotropical genus Erythromelana Townsend, two species previously assigned to this genus, Euptilodegeeria obumbrata (Wulp) and Myiodoriops marginalis Townsend were reinstated as monotypic genera. In the …
White Fringetree, Chionanthus Virginicus, As A Novel Larval Host For Emerald Ash Boer, Don Cipollini
White Fringetree, Chionanthus Virginicus, As A Novel Larval Host For Emerald Ash Boer, Don Cipollini
Biological Sciences Faculty Publications
Emerald ash borer is an invasive Asian pest of ash species in North America. All North American species of ash tested so far are susceptible to it, but there are no published reports of this insect developing fully in non-ash hosts in the field in North America. I report here evidence that EAB can attack and complete development in white fringetree, Chionanthus virginicus L., a species native to the southeastern U.S. that is also planted ornamentally.

Last year we documented in the pages of this newsletter an expedition to the Western Cape of South Africa in search of tachinids for the “Phylogeny of World Tachinidae” project (Cerretti et al. 2013). The project itself was discussed in a separate article (Stireman et al. 2013). In this issue of The Tachinid Times we discuss our expedition to eastern Australia in late 2013. This trip took place so recently that we have yet to fully identify our material and as a result cannot record here all of the taxa we collected. Instead, we will add the taxa to a …

We reported last year (Stireman et al. 2013) in The Tachinid Times on our collaborative project, funded by the U.S. National Science Foundation, to study the phylogeny of Tachinidae on a worldwide scale. Since that report, we have made some significant progress towards our goal of assembling a robust phylogenetic tree for Tachinidae. Notably, Cerretti et al. (in press) completed a phylogenetic study using 135 morphological characters from 180 tachinid genera. Results from this study largely reflect, with some interesting exceptions, what we are finding from preliminary analyses of our molecular data. Although sampling of taxa and genes for the …

D eveloping a structural phylogenetic framework for the family Tachinidae has been an interest of mine since I first started working on tachinids as a graduate student. It was then that I developed a new phylogenetic perspective with which to view the world, and many of the questions I wanted to ask of tachinids depended on some level of phylogenetic knowledge of them. I was surprised at the time that no one had attempted a broad quantitative phylogenetic analysis of the family, and a publication from my thesis work on the Exoristinae (Stireman 2002) became the first such study that …
Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman Iii, Rebecca F. Hazen
Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman Iii, Rebecca F. Hazen
Biological Sciences Faculty Publications
Multitrophic interactions play key roles in the origin and maintenance of species diversity, and the study of these interactions has contributed to important theoretical advances in ecology and evolutionary biology. Nevertheless, most biodiversity inventories focus on static species lists, and prominent theories of diversity still ignore trophic interactions. The lack of a simple interaction metric that is analogous to species richness is one reason why diversity of interactions is not examined as a response or predictor variable in diversity studies. Using plant-herbivore-enemy trophic chains as an example, we develop a simple metric of diversity in which richness, diversity indices (e.g., …

Although tachinids are one of the most diverse families of Diptera (Irwin et al. 2003) and represent the largest group of non-hymenopteran parasitoids (Belshaw 1994), the ecology of most species in the family is poorly known. Most of the studies that have focused on tachinids are related to taxonomic descriptions. Currently, our knowledge is very limited in terms of the diversity and distribution of populations across time and space, especially in the Nearctic and Neotropical Regions (Stireman 2008). There have been a number of recent studies focused on diversity and temporal distributions of tachinids in the Palaearctic Region such as …

Most of the unknown biological diversity of macro-organisms remaining to be discovered and described lies in the tropical regions of the world and consists primarily of insects. Those insects with parasitoid lifestyles constitute a significant portion of insect diversity, yet parasitoids are among the most poorly known of major insect guilds in the humid tropics. Here we describe and analyze the richness of one diverse taxon of parasitoids, flies in the family Tachinidae, reared from Lepidoptera as part of a biological survey of Lepidoptera and their parasitoids in one mid-elevation (2000 m) area in the northeast Ecuadorian Andes. One hundred …

Here we describe the immature stages and ecological associations of Antirrhea adoptiva porphyrosticta Watkins, 1928 (Lepidoptera:Nymphalidae:Morphinae). The cloud forest bamboo, Chusquea scandens Kunth (Bambusoidea: Poaceae), serves as the larval food plant for this butterfly in eastern Ecuador, the first hostplant record for Antirrhea outside the family Arecaceae. The larvae of A. adoptiva porphyrosticta are superficially similar to those of other Antirrhea species. We also provide observations on adult and larval behavior. Caterpillars of this butterfly species are parasitized by tachinid flies, as well as by Ichneumonidae and a newly described braconid wasp.

The 2007 field meeting of the North American Dipterists Society (NADS) was held August 13–16 in southwestern New Mexico, centered in Silver City (at Western New Mexico University), and the surrounding Gila National Forest. This was the first NADS meeting that I have been able to attend, and I think I can speak for all in saying it was enjoyable, productive, and interesting; an overall success. A more detailed account and evaluation of this meeting is available in the 2007 Fly Times article (O’Hara 2007).

Biological Sciences Faculty Publications
Current estimates of the species richness of Tachinidae among geographical provinces suggest that the Neotropical Region harbors the largest number of species and represents a geographic epicenter of tachinid diversification (O’Hara 2006). The Neotropics boasts an impressive fauna consisting of 2864 described species belonging to 822 genera at the time of the Neotropical catalog (Guimarães 1971), making it almost twice as species rich as any other geographic realm (O’Hara 2006; Stireman et al. 2006). This diversity is most apparent at middle elevations (1000– 2000m) along the mountain chains of tropical Central and South America, where tachinids are an abundant and …
Phylogenetic Reconstruction Of Exoristinae Using Molecular Data: A Bayesian Re-Analysis, John O. Stireman Iii
Phylogenetic Reconstruction Of Exoristinae Using Molecular Data: A Bayesian Re-Analysis, John O. Stireman Iii
Biological Sciences Faculty Publications
A few years ago I published the results of a phylogenetic analysis of New World Exoristinae based on molecular data from two genes, 28S rDNA and Elongation Factor 1-alpha (Stireman 2002). In that study I employed parsimony, neighbor joining, and maximum likelihood inference methods to generate phylogenetic reconstructions, and explored a variety of weighting schemes and combinations of the sequence data (i.e. each gene separately and both together). The results of these analyses generally supported recent taxonomic hypotheses (e.g., Herting 1984; Wood 1987; O’Hara and Wood 2004). For example, Tachinidae and Exoristinae were reconstructed as monophyletic in most analyses, as …
