Some Observations On The Nature Of Insect Names, B. Elwood Montgomery Aug 2017

Some Observations On The Nature Of Insect Names, B. Elwood Montgomery

The Great Lakes Entomologist

A recent study of dragonfly names (Montgomery, 1973) has led to a consideration of insect names, especially ancient and early English names. This interest was aroused, chiefly by the statement in Sarot's study of the folklore of the dragonfly from "A Linguistic Approach" that no recognizable name for dragonflies has been found in Anglo-Saxon, classical Latin or ancient Greek. Any language is capable of supplying names for all objects, including insects, which are recognized by its community of speakers. As so many names for dragonflies have been found in modern languages, (95 in English, over 60 in German, about 40 …


Termite Distribution In Michigan, Etdon A. Behr Aug 2017

Termite Distribution In Michigan, Etdon A. Behr

The Great Lakes Entomologist

Subterranean termites have been present in Michigan for a long time. They were reported as being destructive to buildings in 1920 (Anonymous, 1961), and apparently damage done at that time was increasing over what had occurred earlier. Notwithstanding this long time presence of termites in the state a majority of the population still looks upon the termite as a strange insect most likely to be encountered in the South. All too many home owners and building proprietors as well as others are unacquainted with presence of termites in their areas. At the same time monetary loss due to termite attack …


The Life History Of Folsomia Candida (Willem) (Collembola: Isotomidae) Relative To Temperature, Renate M. Snider, James W. Butcher Aug 2017

The Life History Of Folsomia Candida (Willem) (Collembola: Isotomidae) Relative To Temperature, Renate M. Snider, James W. Butcher

The Great Lakes Entomologist

The parthenogenetic mode of reproduction in Collembola, although frequently questioned in the past (Schaller, 1953; Mayer, 1957; Falkenhan, 1932), has only recently been recorded and confirmed for several species; Onychiutus parthenogeneticus Choudhuri (Choudhuri, 1958), Folsomia candida (Willem) (Goto, 1960; Marshall and Kevan, 1962; Green, 1964; Husson and Paldvody, 1967), Folsomia cavicola Cassagnau and Delamare (Goto, 1960), Tullbergia krausbaueri (Bomer) (Hale, 1966; Petersen, 1971), and Isotoma notabilis Schaffer (Petersen, 1971).

Sex-ratios in populations of the above cited species are often unknown. Existing data indicate that the composition of a population may vary with the geographical distribution of the species. Populations of …

The Great Lakes Entomologist

After its initial appearance in August, 1944, as Bulletin of the Illinois Natural History Survey, Vol. 23, Art. I, this work quickly became a classic. With the passage of time it has continued to gain in stature. The great expansion of interest in the Trichoptera, to which Dr. Ross calls attention in his preface to the reprint edition, has been stimulated to a significant degree, by The Caddis Flies of Illinois.

The Great Lakes Entomologist

The English naturalist William C. Hewitson (1806-78) was trained as a surveyor, but various good fortunes enabled him to retire at an early age and devote his attention to the pursuit of natural history. His chief interests were entomology and ornithology, the classic British Oology (183342) being his major contribution to the latter field.


A Milliped New To Michigan (Pselaphognatha: Polyxenus), James R. Brice, Michael T. Barbour Aug 2017

A Milliped New To Michigan (Pselaphognatha: Polyxenus), James R. Brice, Michael T. Barbour

The Great Lakes Entomologist

The authors wish to report the finding of representatives of the genus Polyxenus for the first time in Michigan (Fig. 1). In Bert M. Johnson's survey (1954) of the millipedes of Michigan, no members of the subclass Pselaphognatha were reported.

During the period of September through October 1970, the authors collected over 40 specimens of Polyxenus and observed over 100 in the field. All of the specimens were found in a mature pine stand in Ypsilanti Township.


A List Of The Tenebrionidae Of Michigan (Coleoptera), T.J. Spilman Aug 2017

A List Of The Tenebrionidae Of Michigan (Coleoptera), T.J. Spilman

The Great Lakes Entomologist

The family Tenebrionidae, the darkling beetles, containing more than 14,000 species, is found primarily in the tropics and arid regions. As would therefore be expected, Michigan's cool, moist environment is not attractive to very many tenebrionids. This list contains 50 identified species and six previously recorded species that were not confirmed by me.


An Annotated List Of The Cerambycidae Of Michigan (Coleoptera) Part I, Introduction And The Subfamilies Parandrinae, Prioninae, Spondylinae, Aseminae, And Cerambycinae, D. C.L. Gosling Aug 2017

An Annotated List Of The Cerambycidae Of Michigan (Coleoptera) Part I, Introduction And The Subfamilies Parandrinae, Prioninae, Spondylinae, Aseminae, And Cerambycinae, D. C.L. Gosling

The Great Lakes Entomologist

The Cerambycidae are generally acknowledged as one of the most popular families of Coleoptera, and it is not surprising that they have been collected widely in Michigan. Andrews (1916, 1921, 1929), Hatch (1924), Hubbard and Schwarz (1878), and Wickham (1895), included Cerambycidae in published lists of insects from various localities in the state. The present list, however, is the first to include records of collections made throughout Michigan. Some regions of the state have been rather thoroughly collected, particularly the southeastern counties. Collecting throughout Michigan has been sufficient to consider this list as essentially complete, although continued studies in the …


George Starkey, An Early Seventeenth-Century American Entomologist, Ronald S. Wilkinson Aug 2017

George Starkey, An Early Seventeenth-Century American Entomologist, Ronald S. Wilkinson

The Great Lakes Entomologist

Between the earliest known North American entomological observations made by John White (Wilkinson, 1973a) and Thomas Hariot, and the beginning of more systematic investigations by John Banister (Ewan and Ewan, 1970) and other collectors in the late seventeenth and eighteenth centuries, especially those promoted by the London apothecary and naturalist James Petiver (Stearns, 1952; Wilkinson, 1966), a number of persons wrote about insects observed in British America. However, their remarks were usually very brief, and confined to notices of one or two species. Only a few seventeenth-century investigators actually studied North American insects and related forms in situ with any …


Definition Of The Subfamily Hedobiinae Based On Larval Characteristics (Coleoptera: Anobiidae), Manuel G. De Viedma Aug 2017

Definition Of The Subfamily Hedobiinae Based On Larval Characteristics (Coleoptera: Anobiidae), Manuel G. De Viedma

The Great Lakes Entomologist

Recently, Espanol (1968, 1970) redefined the subfamily Hedobiinae and, using the anatomy of adults, presented a key to separate the eight genera which form it. He also introduced some notable modifications, among them the inclusion of Ptilineurus and Clada in the subfamily and the elevation of Ptinomorphus Mulsant and Rey to generic rank. The latter genus includes, among others, the species P. imperialis Linnaeus and regalis Duftschmid, from Europe and P. granosus LeConte and angularus Fall from the United States of America.


The Morphology And Histology Of New Sex Pheremone Glands In Male Scorpionflies, Panorpa And Brachypanorpa (Mecoptera: Panorpidae And Panorpodidae), Albert R. Thornhill Aug 2017

The Morphology And Histology Of New Sex Pheremone Glands In Male Scorpionflies, Panorpa And Brachypanorpa (Mecoptera: Panorpidae And Panorpodidae), Albert R. Thornhill

The Great Lakes Entomologist

The n~orphology and histology of a previously undescribed sex pheromone gland in male scorpionflies of the genus Panorpa (Mecoptera: Panorpidae) and a morphologically similar gland in Brachypanorpa (Mecoptera: Panorpodidae) are described and discussed. The gland and the associated pheromone dispersing structure consist of an eversible pouch that lies in the ventral part of the male genital bulb at the point where the basistyles diverge. The glandular layer of epithelium is composed of three types of cells that vary in size between species of Panorpa and between Panorpa and Brachyponorpa. It is suggested that the gland may have evolved from …


Moth Species New To Michigan, John H. Newman, Mogens C. Nielsen Aug 2017

Moth Species New To Michigan, John H. Newman, Mogens C. Nielsen

The Great Lakes Entomologist

This is a compilation of moth species previously unrecorded from Michigan. Moore's (1955) publication has been critically examined necessitating some specific changes. All questionable material has been determined by present day specialists in their particular fields. The McDunnough (1938) checklist is followed in the arrangement of the new data together with most of the recent changes in nomenclature as presented by Forbes (1948, 1954, 1960), Hardwick (1970), Hodges (1971), and Covell (1970, 1971). With the advent of more sophisticated collecting equipment and the easier access to Michigan's Upper Peninsula a total of 154 species has been added. Many institutional and …


Moths Taken In Berrien County, Michigan (With 102 New County Records), Russell A. Rahn Aug 2017

Moths Taken In Berrien County, Michigan (With 102 New County Records), Russell A. Rahn

The Great Lakes Entomologist

(excerpt) Moore (1955) published a listing of the moths of Michigan, exclusive of the Tineoidea, Other writers (anon., 1968; Voss, 1970) have extended the list of Michigan records. During the fall of 1970, and through the summer of 1971, I lived in Sawyer, Berrien County and collected a number of records new for that area. At the encouragement of M.C. Nielsen, a listing of these records is made available.


Cover Illustration: The Well-Dressed Entomologist, Ronald S. Wilkinson Aug 2017

Cover Illustration: The Well-Dressed Entomologist, Ronald S. Wilkinson

The Great Lakes Entomologist

This issue's cover illustration is the frontispiece to a classic work of eighteenth-century entomology, Moses Harris' The Aurelian, which began to appear in parts in 1758 and was published entire in 1766 (Lisney, 1960). Harris, who was the illustrator as well as the author, pictures the contemporary entomologist with part of his array of collecting equipment. (By tradition, the frontispiece is supposed to be a self-portrait.)


Five Species Of The Ant Genus Acanthomyops (Hymenoptera: Formicidae) At The Edwin S. George Reserve In Southern Michigan, Mary Talbot Aug 2017

Five Species Of The Ant Genus Acanthomyops (Hymenoptera: Formicidae) At The Edwin S. George Reserve In Southern Michigan, Mary Talbot

The Great Lakes Entomologist

This paper supplements one written ten years ago (Talbot 1963) concerning the Acanthomyops nesting in a two square mile area in south eastern Michigan. It presents a fifth species (A. subglaber) for the E. S. George Reserve, gives flight activities of A. claviger, adds a description of a method used by A. murphyi to invade Lasius neoniger colonies and extends some brood and flight records and habitat ranges.


John White's Drawings Of Papilio Glaucus L. (Lepidoptera: Papilionidae): New Light On The 'First American Butterfly' And The Problem Of Glaucus Versus Antilochus L. Part I: White To Moffet, Ronald S. Wilkinson Aug 2017

John White's Drawings Of Papilio Glaucus L. (Lepidoptera: Papilionidae): New Light On The 'First American Butterfly' And The Problem Of Glaucus Versus Antilochus L. Part I: White To Moffet, Ronald S. Wilkinson

The Great Lakes Entomologist

All American lepidopterists are familiar with the "first picture of an American butterfly." William J. Holland's account of one of John White's watercolors of Papilio glaucus L. first appeared as a separate article (Holland, 1929), and was later adapted for the second edition of his immensely popular The Butterfly Book (Holland, 1931). Sub sequent research has added many facts to our knowledge of White's life, and much more can now be said about his paintings and later use of them. A reappraisal of the first identifiable record of a North American butterfly is now possible, and, more important to taxonomists, …


Perlodidae (Plecoptera) Of Wisconsin, William L. Hilsenhoff, Steven J. Billmyer Aug 2017

Perlodidae (Plecoptera) Of Wisconsin, William L. Hilsenhoff, Steven J. Billmyer

The Great Lakes Entomologist

The family Perlodidae is one of the most abundant and widespread in the order Plecoptera. These stoneflies occur in a wide variety of clean-water habitats and as indicator organisms have potential for assessing water quality. Studies of this family in Wisconsin prior to 1965 were limited to occasional collections reported by Needham and Claassen (1925) and Frison (1935, 1937, 1942). In 1965 and 1966 a survey of the Wisconsin River and its tributaries yielded nymphs of 11 species of Isoperla (W. Hisenhoff, unpublished report), and later, nymphs and adults of 9 species were found in the Pine-Popple River (Hilsenhoff and …


The Neuroptera - Suborder Planipennia Of Wisconsin Part Iii - Mantispidae, Ascalaphidae, Myrmeleontidae And Coniopterygidae, Alvin L. Throne Aug 2017

The Neuroptera - Suborder Planipennia Of Wisconsin Part Iii - Mantispidae, Ascalaphidae, Myrmeleontidae And Coniopterygidae, Alvin L. Throne

The Great Lakes Entomologist

This part concludes the Neuroptera-Suborder Planipennia of Wisconsin. In Parts I and I1 (Throne 1971a, b) no keys to the species were included because satisfactory keys were readily available. However, keys are included in Part 111 either because satisfactory keys are not available or because simpler keys than those available prove adequate for the few Wisconsin species. Whenever possible I have used macroscopic structural characters. In order to separate two species of Coniopterygidae I found it necessary to use male genitalic characters. I have made free use of the keys of Dr. Martin Meinander (1972) in constructing the key for …


Notes On The Brown Widow Spider, Latrodectus Geometricus (Araneae: Theridiidae) In Brazil, Marilyn P. Anderson Aug 2017

Notes On The Brown Widow Spider, Latrodectus Geometricus (Araneae: Theridiidae) In Brazil, Marilyn P. Anderson

The Great Lakes Entomologist

Three species of the cosmopolitan genus Latrodectus were reported by Bucherl (1964) as occurring in Brazil: L. mactans mactans (Fabricius) from Recife, Pernambuco and from P6rto Alegre, Rio Grande do Sul; L. curacaviensis (Muller) from the beaches of Guanabara and Bahia; and L. geometricus C. L. Koch from the city of P6rto Alegre, Rio Grande do Sul and from the states of Minas Gerais, Bahia and Rio de Janeiro. Levi (1959) cited records of L. geometricus from the states of Paraiba, Pernarnbuco, Minas Gerais and Rio de Janeiro. In the United States L. geometricus has been reported as an introduced …


Eastern Range Extension For Oarisma Powesheik Parker (Lepidoptera: Hesperiidae), Richard W. Holzman Aug 2017

Eastern Range Extension For Oarisma Powesheik Parker (Lepidoptera: Hesperiidae), Richard W. Holzman

The Great Lakes Entomologist

Excerpt: According to Klotz (1951), the range of Oarisma powesheik Parker (Figs. 1, 2) extends from Montana east to Iowa, Wisconsin, Northern Illinois, and Michigan. The first Michigan record was in Kent County made in 1893 by Wolcott who found it at Lamberton Lake. Later powesheik was collected by Newcomb in 1930, McAlpine in 1937 and 1963, Nielsen (1970) in 1963 and 1964, and Warczynski in 1968 at the same area. It was also taken at nearby Button Lake which flows into Lamberton Lake. In his list of Michigan Butterflies, Moore (1960) gave the fllght period as July 9-12, although, …


Allergen Homologs In The Euroglyphus Maynei Draft Genome, S. Dean Rider, Majorie S. Morgan, Larry G. Arlian Aug 2017

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, …


Rna Interference In The Asian Longhorned Beetle: Identification Of Key Rnai Genes And Reference Genes For Rt-Qpcr, Thais B. Rodrigues, Ramesh Kumar Dhandapani, Jian J. Duan, Subba Reddy Palli Aug 2017

Rna Interference In The Asian Longhorned Beetle: Identification Of Key Rnai Genes And Reference Genes For Rt-Qpcr, Thais B. Rodrigues, Ramesh Kumar Dhandapani, Jian J. Duan, Subba Reddy Palli

Entomology Faculty Publications

Asian Longhorned Beetle (ALB) Anoplophora glabripennis is a serious invasive forest pest in several countries including the United States, Canada, and Europe. RNA interference (RNAi) technology is being developed as a novel method for pest management. Here, we identified the ALB core RNAi genes including those coding for Dicer, Argonaute, and double-stranded RNA-binding proteins (dsRBP) as well as for proteins involved in dsRNA transport and the systemic RNAi. We also compared expression of six potential reference genes that could be used to normalize gene expression and selected gapdh and rpl32 as the most reliable genes among different tissues and stages …


Phytoplasma Infection Of A Tropical Root Crop Triggers Bottom-Up Cascades By Favoring Generalist Over Specialist Herbivores, Kris A. G. Wyckhuys, Ignazio Graziosi, Dharani Dhar Burra, Abigail Jan Walter Aug 2017

Phytoplasma Infection Of A Tropical Root Crop Triggers Bottom-Up Cascades By Favoring Generalist Over Specialist Herbivores, Kris A. G. Wyckhuys, Ignazio Graziosi, Dharani Dhar Burra, Abigail Jan Walter

Entomology Faculty Publications

Global interest on plant-microbe-insect interactions is rapidly growing, revealing the multiple ways in which microorganisms mediate plant-herbivore interactions. Phytopathogens regularly alter whole repertoires of plant phenotypic traits, and bring about shifts in key chemical or morphological characteristics of plant hosts. Pathogens can also cause cascading effects on higher trophic levels, and eventually shape entire plant-associated arthropod communities. We tested the hypothesis that a Candidatus Phytoplasma causing cassava witches’ broom (CWB) on cassava (Manihot esculenta Grantz) is altering species composition of invasive herbivores and their associated parasitic hymenopterans. We conducted observational studies in cassava fields in eastern Cambodia to assess …


Description Of A New Genus Of Primitive Ants From Canadian Amber, With The Study Of Relationships Between Stem- And Crown-Group Ants (Hymenoptera: Formicidae), Leonid H. Borysenko Aug 2017

Description Of A New Genus Of Primitive Ants From Canadian Amber, With The Study Of Relationships Between Stem- And Crown-Group Ants (Hymenoptera: Formicidae), Leonid H. Borysenko

Insecta Mundi

A detailed study of the holotype of Sphecomyrma canadensis Wilson, 1985 (Hymenoptera: Formicidae) from Canadian amber has led to the conclusion that the specimen belongs to a new genus, here named Boltonimecia gen.n. Since the taxonomy of stem-group ants is not well understood, in order to find the taxonomic position of this genus, it is necessary to review the classification of stem-group ants in a study of their relation to crown-group ants. In the absence of data for traditional taxonomic approaches, a statistical study was done based on a morphometric analysis of antennae. Scape elongation is believed to play an …


Review Of Carelli, A., And M.L. Monné, 2015. Taxonomic Revision Of Phygopoda Thomson, 1864 And Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007 (Insecta: Coleoptera: Cerambycidae: Cerambycinae), Robin O. S. Clarke Aug 2017

Review Of Carelli, A., And M.L. Monné, 2015. Taxonomic Revision Of Phygopoda Thomson, 1864 And Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007 (Insecta: Coleoptera: Cerambycidae: Cerambycinae), Robin O. S. Clarke

Insecta Mundi

The taxonomic history of the rhinotragine genera Phygopoda Thomson, 1864 and Pseudophygopoda Tavakilian and Peñaherrera-Leiva, 2007 (Coleoptera: Cerambycidae: Cerambycinae) are discussed, and evidence is presented to suggest that some recent taxonomic changes made by Carelli and Monné (2015) were unjustified. Consequently, Phygopoda nigritarsis Gounelle, 1911 is moved to the genus Neophygopoda Melzer, 1933, creating the new combination Neophygopoda nigritarsis, the genera Panamapoda Clarke, 2014 and Paraphygopoda Clarke, 2014 are revalidated, and the species Paraphygopoda viridimicans (Fisher, 1952) and Paraphygopoda nappae Clarke, 2014 are also revalidated.


Development Of Rnai Method For Screening Candidate Genes To Control Emerald Ash Borer, Agrilus Planipennis, Thais B. Rodrigues, Lynne K. Rieske, Jian J. Duan, Kanakachari Mogilicherla, Subba Reddy Palli Aug 2017

Development Of Rnai Method For Screening Candidate Genes To Control Emerald Ash Borer, Agrilus Planipennis, Thais B. Rodrigues, Lynne K. Rieske, Jian J. Duan, Kanakachari Mogilicherla, Subba Reddy Palli

Entomology Faculty Publications

The ingestion of double-strand RNAs (dsRNA) targeting essential genes in an insect could cause mortality. Based on this principle, a new generation of insect control methods using RNA interference (RNAi) are being developed. In this work, we developed a bioassay for oral delivery of dsRNA to an invasive forest and urban tree pest, the emerald ash borer (EAB, Agrilus planipennis). EAB feeds and develops beneath the bark, killing trees rapidly. This behavior, coupled with the lack of a reliable artificial diet for rearing larvae and adults, make them difficult to study. We found that dsRNA is transported and processed …


The Interommatidial Bristle Variability Of Diptera, Kimberly Palmer Aug 2017

The Interommatidial Bristle Variability Of Diptera, Kimberly Palmer

Honors College Theses

Insects of the order Diptera are a popular biological model for understanding morphological trait evolution. One area of particular interest is the development of the compound eyes. While the development of ommatidia and photoreceptors has been thoroughly studied in this case, little attention has been paid to the interommatidial bristles (IOBs) present on the eyes of some dipteran families. A preliminary survey suggested that these bristles exhibit high variability among IOB families on multiple taxonomic levels and are not uniformly present or absent in any suborder of the Diptera. To confirm this observation, I conducted a literature search to …


Natural Enemies Partially Compensate For Warming Induced Excess Herbivory In An Organic Growth System, Orsolya Beleznai, Jamin Dreyer, Zoltán Tóth, Ferenc Samu Aug 2017

Natural Enemies Partially Compensate For Warming Induced Excess Herbivory In An Organic Growth System, Orsolya Beleznai, Jamin Dreyer, Zoltán Tóth, Ferenc Samu

Entomology Faculty Publications

Predators can limit prey abundance and/or levels of activity. The magnitudes of these effects are contingent on predator and prey traits that may change with environmental conditions. Aberrant thermal regimes could disrupt pest suppression through asymmetric effects, e.g. heat-sensitive predator vs. heat-tolerant prey. To explore potential effects of warming on suppressing pests and controlling herbivory in a vegetable crop, we performed laboratory experiments exposing an important pest species to two spider predator species at different temperatures. Heat tolerance was characterised by the critical thermal maxima parameter (CTM50) of the cucumber beetle (Diabrotica undecimpunctata), wolf spider (Tigrosa helluo …


Ecological And Organic Life Safety Concerns Of Hfo-1234yf, Alberni V. Ruiz Aug 2017

Ecological And Organic Life Safety Concerns Of Hfo-1234yf, Alberni V. Ruiz

STAR Program Research Presentations

While at NOAA my research was directed by the inquiry of whether or not HFO-1234yf, a new compound being introduced into coolant system and replacing greenhouse gases HFC, is harmful to organic life. Using the computer program Matlab I was able to develop figures that represented the concentration of HFO-1234yf (HFO) in 12 different tower locations throughout the country. Comparing and contrasting concentrations of this HFO compound at each site led me to the question the possible harmful side effects this compound could bring to organic life due to the fact that concentration levels are increasing, with one factor being …
