Insect Behaviour. Symposium No. 3 Of The Royal Entomological Society Of London. Ed. P. T. Haskell. London: The Royal Entomological Society, 1966. Viii, 113 Pp. $6.35. .., Anthony Eve

The Great Lakes Entomologist

Excerpt: The science of zoology is expanding at such a rate that it is difficult for even the relatively narrow specialist to keep up with the ever- increasing literature on his subject, and almost impossible to assimilate recent findings in the entire field of zoological research. The international congresses of zoology and entomology have helped, considerably by facilitating personal contact between workers of different nationalities. On a more modest scale, the symposia of the Royal Entomological Society of London have provided a useful means of bringing together entomologists in an atmosphere conducive to the free exchange of ideas and information.

Laminating Lepidoptera For Educational Use, Darryl Quidort

The Great Lakes Entomologist

Excerpt: A convenient method of teaching farmers, 4-H members and students to recognize various species of Lepidoptera is now being used in Michigan with wide success. In the process, insect wings are mounted on cardboard and sealed between layers of clear plastic. The resulting "laminations" have several advantages over pin-mounted Lepidoptera, and are admirably suited for any use that requires constant handling. The finished mounts are impervious to museum pests, are dust-proof, may be cleaned with ease, and are easily stored in a loose-leaf binder. The plastic is flexible, thus danger of damage from bending is slight.

The Behavior Of Atlanticus Testaceus (Orthoptera: Tettigoniidae) On The E.S. George Reserve, Michigan, S. K. Gangwere

The Great Lakes Entomologist

Several reports deal in part with the systematics, distribution, or habits of one or another of the shield-backed katydids of the orthopteran genus Atlanticus. Included are Blatchley (1920), Cantrall (1943), Caudell (1907), Davis (1893), Hebard (1934), McNeill (1891), Rehn and Hebard (1916), and Scudder (1894). One species of the genus, A. testaceus (Scudder), is found commonly throughout Michigan and has interesting habits. As the species' feeding behavior was poorly understood, the author undertook an investigation dealing with that subject. The results are in press. During the course of that study much information was obtained on certain non-feeding aspects of the …

A New Species Of Thraulodes From New Mexico (Ephemeroptera: Leptophlebiidae), Richard W. Koss

The Great Lakes Entomologist

While working on the Ephemeroptera collection in the Entomology Museum at Michigan State University, the author came upon a single specimen of Thraulodes which appeared to be a new species. Although it is only in fair condition (the preserving fluid having dissipated under field conditions), the colors are well preserved and very distinctive. The specimen was sent to Dr. Jay R. Traver, University of Massachusetts, who confirmed suspicions that the specimen was new. I have been informed by Dr. Traver that she and Dr. George F. Edmunds Jr. are presently engaged in a revisionary study of the genus for North …

Another Record Of Williamsonia Fletcheri In Michigan (Odonata: Corduliidae), David F. Foley

The Great Lakes Entomologist

Excerpt: Williamsonia fletcheri Williamson was first taken in the United States in the upper peninsula of Michigan near Manistique, Schoolcraft County (Gloyd, 1932). On June 4, 1966, I collected two males of this rare species at Island Lake, a small lake heavily overgrown with jack pine and poplar in southeastern Grand Traverse County. The specimens were identified by Mrs. Leonora Gloyd of the University of Michigan. This is the first report of this species from the lower peninsula of Michigan, and the second for the United States.

Some Notes On Heteropteran Trichobothria, Carl W. Schaefer

The Great Lakes Entomologist

Excerpt: There has been much recent interest in the comparative morphology of the Heteroptera. This work has emphasized the land bugs, or Geocorisae, and has been concerned with working out the relationships and taxonomic placement of the higher categories (categories above the genus), and with the phylogenetic lines and sequences of these higher categories. The geocorisine groups with which I have been most concerned are in the closely related superfamilies Lygaeoidea, Pyrrho- coroidea, and Coreoidea (see Schaefer, 1964, for a discussion of the relationships among these groups). Another superfamily, the Pentatomoidea, is less closely related. All four of these superfamilies …

A Review Of The North American Species Of The Genus Otites Latreille, With Descriptions Of Two New Species (Diptera: Otitidae), George C. Steyskal

The Great Lakes Entomologist

Excerpt: In 1961 (Steyskal, 1961), I placed the genus Otites in a key to the North American genera of Otitidae and indicated the synonymy of the genus Ortalimyia. Bibliography and synonymy of the hitherto known species of our area will be found in the Catalog of the Diptera of America North of Mexico (Stone et al., 1965). The only previously published key to our species was by Hendel (1911, as Ortalis), wherein were included Cevoxys latiusculus (Loew) and the four species now known as Otites bimaculahs (Hendel), 0. evythvocephala (Hendel), 0. pyvvhocephala (Loew), and O. stigma (Hendel). The present treat- …

The Genus Phragmatobia In North America, With The Description Of A New Species (Lepidoptera: Arctiidae), Julian P. Donahue, John H. Newman

The Great Lakes Entomologist

Excerpt: This paper, based on the examination of 1,879 specimens, serves to resolve the taxonomic problems involving the three North American species of Phragmatobia. The genus Phragmatobia, the ruby tiger moths, has had a checkered history since it was described by Stephens in 1829 (type, by monotypy, Noctua j'uliginosa Linnaeus, 1758). Although many species have been described in or transferred to this genus, in both the Old and New Worlds, most of them have been removed to other genera. By 1902 Dyar recognized only two North American species, a status since then unchanged (McDunnough, 1938; Forbes, 1960). Despite the recent …

A Window Of Opportunity: Subdominant Predators Can Use Suboptimal Prey, Kelly A. Jackson, Joshua S. Mccord, Jennifer A. White

Entomology Faculty Publications

Introduced species have been linked to declines of native species through mechanisms including intraguild predation and exploitative competition. However, coexistence among species may be promoted by niche partitioning if native species can use resources that the invasive species cannot. Previous research has shown that some strains of the aphid Aphis craccivora are toxic to a competitively dominant invasive lady beetle, Harmonia axyridis. Our objective was to investigate whether these aphids might be an exploitable resource for other, subdominant, lady beetle species. We compared larval development rate, survival, and adult weight of five lady beetle species in no-choice experiments with …

The Longhorned Beetles (Coleoptera: Cerambycidae) Of Tennessee: Distribution Of Species, Seasonal Adult Activity, And New State Records, William E. Klingeman, Nadeer N. Youssef, Jason B. Oliver, Joshua P. Basham

Agricultural and Environmental Sciences Faculty Research

Efforts to document species of longhorned beetles (Coleoptera: Cerambycidae) occurring in Tennessee have not been updated since 1973. To address this knowledge gap, institutional, research, and private collections in Tennessee were reviewed to provide faunal distribution assessments and seasonal activity data for the cerambycid beetle species active in Tennessee. Examinations of 9,918 specimens and records yielded a list of 230 cerambycid beetle species within 5 subfamilies. Twenty-seven species are reported as new state records from Tennessee. Adult seasonal activity data that were recorded on specimen labels are presented. Where available, notes on collection method, adult resources, and larval host plants …

Swainsonine Biosynthesis Genes In Diverse Symbiotic And Pathogenic Fungi, Daniel Cook, Bruno G. G. Donzelli, Rebecca Creamer, Deana L. Baucom, Dale R. Gardner, Juan Pan, Neil Moore, Stuart B. Krasnoff, Jerzy W. Jaromczyk, Christopher L. Schardl

Plant Pathology Faculty Publications

Swainsonine—a cytotoxic fungal alkaloid and a potential cancer therapy drug—is produced by the insect pathogen and plant symbiont Metarhizium robertsii, the clover pathogen Slafractonia leguminicola, locoweed symbionts belonging to Alternaria sect. Undifilum, and a recently discovered morning glory symbiont belonging to order Chaetothyriales. Genome sequence analyses revealed that these fungi share orthologous gene clusters, designated “SWN,” which included a multifunctional swnKgene comprising predicted adenylylation and acyltransferase domains with their associated thiolation domains, a β-ketoacyl synthase domain, and two reductase domains. The role of swnK was demonstrated by inactivating it in M. robertsii through homologous …

Variation In Dna Methylation Is Not Consistently Reflected By Sociality In Hymenoptera, Karl M. Glastad, Samuel V. Arsenault, Kim L. Vertacnik, Scott M. Geib, Sasha Kay, Bryan N. Danforth, Sandra M. Rehan, Catherine R. Linnen, Sarah D. Kocher, Brendan G. Hunt

Biology Faculty Publications

Changes in gene regulation that underlie phenotypic evolution can be encoded directly in the DNA sequence or mediated by chromatin modifications such as DNA methylation. It has been hypothesized that the evolution of eusocial division of labor is associated with enhanced gene regulatory potential, which may include expansions in DNA methylation in the genomes of Hymenoptera (bees, ants, wasps, and sawflies). Recently, this hypothesis garnered support from analyses of a commonly used metric to estimate DNA methylation in silico, CpG content. Here, we test this hypothesis using direct, nucleotide-level measures of DNA methylation across nine species of Hymenoptera. In doing …

Returns To Research And Outreach For Integrated Pest Management Of Western Flower Thrips Infesting French Bean And Tomato In Kenya, E. A. Mujuka, H. Affognon, B. W. Muriithi, S. Subramanian, P. Irungu, J. Mburu

All Peer-Reviewed Publications

Thrips, Frankliniella occidentalis (Pergande), is a major invasive pest that causes extensive yield losses in French bean and tomato in Kenya. Thrips management is based on the application of pesticides. In addition to increased environmental risks associated with pesticides, frequent use of these chemicals increases production costs and pesticide resistance. Furthermore, exports are restricted due to non-compliance to maximum residue levels in important consumer export markets, especially the European Union (EU). This study was conducted to estimate the potential benefits of the effectiveness of the icipe-developed strategy for control of western flower thrips before dissemination of the technology in Kenya, …

Do The Mechanisms Modulating Host Preference In Holometabolous Phytophagous Insects Depend On Their Host Plant Specialization? A Quantitative Literature Analysis, Christophe Petit, Stéphane Dupas, Denis Thiéry, Claire Capdevielle-Dulac, Bruno Le Ru, Myriam Harry, Paul André Calatayud

All Peer-Reviewed Publications

In holometabolous phytophagous insects, adult females and larvae determine host plant selection through oviposition and feeding preferences. Pre-imaginal and/or imaginal experiences with plant chemical cues can modulate these preferences. Various studies found evidence, or not, of host preference modulation through previous experience but they appear to contradict each other. Most probably, modulation of host preference depends on the degree of specialization of the insects. Our literature analysis revealed that the positive influence of experience in the modulation of host plant preference occurred equally in polyphagous, oligophagous and monophagous species, but was significantly more influenced by the phylogeny of the insect …

Exposing Problems Teaching Students Morphological Species Identification, Trevor Stamper, Lauren Weidner, Gregory Nigoghosian, Ludmila D. Nunes

IMPACT Presentations

When dealing with physical remains, morphological assessment for species is a traditional approach to entomological specimen identification. A dichotomous key guides the user through taxa determination for a specimen by providing a series of dual-choice nodes that center around morphological differences. Each nodal choice leads to either a new set of dichotomous choices or a taxa decision. We evaluated student’s ability to utilize a dichotomous key down to species for a limited set of taxa, by reviewing their nodal decisions along with their confidence level using a Likert scale (1-5).

Along with individual decision recording, students conducted a post-decision group …

Intraguild Interactions And Behavior Of Spodoptera Frugiperda And Helicoverpa, José P. F. Bentivenha, Débora Goulart Montezano, Thomas E. Hunt, Edson L. L. Baldin, Julie A. Peterson, Vinicius S. Victor, Luiz E. R. Pannuti, Ana María Vélez, Silvana L. Vieira De Paula Moraes

Department of Entomology: Faculty Publications

Background: Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is one of the major pests of maize, and is in the same feeding guild of the noctuid pests, Helicoverpa zea (Boddie), and H. armigera (Hübner), recently reported in South and North America. The intraguild interactions of these species were assessed in laboratory and field conditions by determining the survival of larvae in interactions scenarios with non-Bt maize silks and ears. Moreover, a video-tracking system was utilized to evaluate behavioral parameters during larval interactions in scenarios with or without food.

Results: In intraguild interactions, S. frugiperda had greater survival (55 …

Genetic Structure And Diversity Of Western Flower Thrips, Frankliniella Occidentalis In A French Bean Agroecosystem Of Kenya, P. Hondelmann, J. O. Nyasani, S. Subramanian, R. Meyhöfer

All Peer-Reviewed Publications

Western flower thrips (WFT) (Frankliniella occidentalis) is an introduced pest that harms French bean production in Kenya and other countries. Since new WFT management approaches are being developed, a closer look at the genetic makeup of WFT populations can give new insights into source habitats, crop colonization patterns or host plant preferences, which are prerequisites for integrated pest management (IPM) strategies. For this purpose, we used six microsatellite loci to analyse the genetic structure, diversity and gene flow of WFT sampled on French beans, intercrops and weeds in Kenyan French bean production areas. The results of this preliminary study indicate …

Evaluation Of Onion (Allium Cepa) Germplasm Entries For Resistance To Onion Thrips, Thrips Tabaci (Lindeman) In Tanzania, Gabriel Michael Njau, Agnes M.S. Nyomora, Fekadu Fufa Dinssa, Jian Cheng Chang, P. Malini, S. Subramanian, R. Srinivasan

All Peer-Reviewed Publications

Onion thrips, Thrips tabaci (Lindeman), is a prominent species infesting onion and tomato in the northern highlands of Tanzania. It causes considerable leaf damage by direct feeding and also transmits the Iris yellow spot virus (IYSV). Hence, one of the objectives of this study was to identify the most resistant onion entries against T. tabaci. One highly resistant (VI038552) and two resistant onion entries (VI038512 and AVON 1067) were identified against T. tabaci. Besides thrips resistance, the bulb size of VI038512 was also equivalent to one of the commercial varieties, Texas. The highly resistant VI038552 recorded the highest yield, followed …
