Flight Period And Species Composition Of Sirex (Hymenoptera: Siricidae) And Associated Deladenus (Nematoda: Neotylenchidae) Within Arkansas Pine Forests, Danielle Keeler

Graduate Theses and Dissertations

The European woodwasp, Sirex noctilio F. (Hymenoptera: Siricidae), which is a known destructive pest of pine in the southern hemisphere was recently discovered in the eastern United States. Before we can understand how S. noctilio may affect pine forests throughout the United States, we need a better understanding of native Sirex and the role they play in the ecosystem. The objectives of this research were to 1) determine species composition and flight period for native Sirex; 2) confirm presence of parasitic nematodes, Deladenus (Nematoda: Neotylenchidae), within adult Sirex; 3) investigate Deladenus parasitism rates; 4) verify the number of Deladenus species …

Chromosomal Patterns In Populations Of The Black Fly Simulium Fibrinflatum Twinn (Diptera: Simuliidae), Kyle Parks

All Theses

Cryptic species are an important component of biodiversity, although most cryptic species have yet to be discovered. Cytogenetic studies of polytene chromosomes offer a unique level of resolution for detecting cryptic species in the family Simuliidae. Simulium fibrinflatum is a black fly morphospecies that is suspected to contain cryptic species because of its broad geographic range and variable pupal gill structure. Populations of Simulium fibrinflatum from the Saugahatchee River, AL; Anthony Shoals, GA; LaHave River, Nova Scotia; Westfield River, MA; Chauga River, SC; and Enoree River, SC, were sampled and cytogenetically analyzed to test for the presence of cryptic species. …

Palaeoenvironmental Shifts Drove The Adaptive Radiation Of A Noctuid Stemborer Tribe (Lepidoptera, Noctuidae, Apameini) In The Miocene, Emmanuel F.A. Toussaint, Fabien L. Condamine, Gael J. Kergoat, Claire Capdevielle-Dulac, Jérôme Barbut, Jean François Silvain, Bruno P. Le Ru

All Peer-Reviewed Publications

Between the late Oligocene and the early Miocene, climatic changes have shattered the faunal and floral communities and drove the apparition of new ecological niches. Grassland biomes began to supplant forestlands, thus favouring a large-scale ecosystem turnover. The independent adaptive radiations of several mammal lineages through the evolution of key innovations are classic examples of these changes. However, little is known concerning the evolutionary history of other herbivorous groups in relation with this modified environment. It is especially the case in phytophagous insect communities, which have been rarely studied in this context despite their ecological importance. Here, we investigate the …

Surveillance Of Mosquitoes For Arthropod-Borne Viruses In El Paso, Tx., Stephanie Coronado, Douglas Watts

COURI Symposium Abstracts, Summer 2012

West Nile encephalitis is the only arthropod-borne virus that causes annual cases of human illness in El Paso, Texas. Cases more commonly affect the young and elderly and the illness may range from a mild febrile disease to fatal encephalitis. The primary vector(s) of West Nile virus are Culex species mosquitoes, including Culex tarsalis and Culex quinquefaciatus. Further, surveillance is needed to determine the relative importance of these and possibly other mosquito species. More recently, cases of dengue fever and fatal hemorrhagic fever have been occurring in communities along the USA-Mexico border. Dengue has been endemic in Mexico since the …

Molecular Identification Of Synanthedonini Members (Lepidoptera: Sesiidae) Using Cytochrome Oxidase I, Jason A. Hansen, William E. Klingeman, J. Kevin Moulton, Jason B. Oliver, Mark T. Windham, Aijun Zhang, Robert N. Trigiano

Agricultural and Environmental Sciences Faculty Research

Many North American sesiid moths within Synanthodonini have been studied extensively because their feeding activity can cause detrimental economic and esthetic impacts to many commercially important ornamental and native plant species. Recent discoveries of nonnative clearwing moth pest introductions [e.g., Synanthedon myopaeformis (Borkh.)], reinforce the need for reliable and accurate molecular diagnostic tools that can be used by nontaxonomic experts, particularly when juvenile life stages are recovered from infested host-plant tissues. Cytochrome oxidase I (cox I) previously has been used to successfully identify species and resolve species complexes. In this study, the cox I phylogeny inferred from sequences generated from …

Penetration Of Termiticide Treatments Into Gravel Used As A Construction Fill Material, Chris J. Peterson

Midsouth Entomologist

The penetration of five termiticidal suspensions (Termidor, Premise, Talstar, Phantom, and Transport) was examined in packed columns in the laboratory, in which each column incorporated a top gravel layer and a lower soil layer. This simulates common building practices in some parts of the United States. The highest doses were usually found at the top of the soil layer beneath the gravel, indicating that the applied suspension (at either the normal labeled volume or a higher volume allowed for treating gravel) penetrated to the soil below at levels sufficient to kill termites (Isoptera: Rhinotermitidae). The active ingredients were retained by …

Insect Succession On Pig Carrion In North-Central Mississippi, J. Goddard, D. Fleming, J. L. Seltzer, S. Anderson, C. Chesnut, M. Cook, E. L. Davis, B. Lyle, S. Miller, E. A. Sansevere, W. Schubert

Midsouth Entomologist

A freshly-euthanized 90 kg Yucatan mini pig, Sus scrofa domesticus, was placed outdoors on 21 March 2012, at the Mississippi State University South Farm and two teams of students from the Forensic Entomology class were assigned to take daily (weekends excluded) environmental measurements and insect collections at each stage of decomposition until the end of the semester (42 days). Assessment of data from the pig revealed a successional pattern similar to that previously published – fresh, bloat, active decay, and advanced decay stages (the pig specimen never fully entered a dry stage before the semester ended). Over 2,300 immature and …

A Century And A Half Of Research On The Stable Fly, Stomoxys Calcitrans (L.) (Diptera: Muscidae), 1862-2011: An Annotated Bibliography, K. M. Kneeland, Steven R. Skoda, Jerome A. Hogsette, A. Y. Li, Jaime Molina-Ochoa, Kimberly Hutchinson Lohmeyer, John E. Foster

Department of Entomology: Faculty Publications

The stable fly, Stomoxys calcitrans, is a cosmopolitan pest of livestock, wild animals, pets, and humans. It is a primary pest of cattle in the United States, estimated to cause more than $1 billion in economic losses annually. It also causes dissension at the rural-urban interface and is a problem in recreation areas such as Florida beaches and the Great Lakes. Due to its pestiferous nature and painful bite, methods to control stable flies have been investigated for over a century. A large amount of research has been reported on stable fly biology, ecology, genetics, physiology, and vector competence. …

Wing Shape As An Indicator Of Larval Rearing Conditions For Aedes Albopictus And Aedes Aegypti (Diptera: Culicidae), C R. Stephens, Steven A. Juliano

Faculty Publications – Biological Sciences

Estimating a mosquito's vector competence, or likelihood of transmitting disease, if it takes an infectious bloodmeal, is an important aspect of predicting when and where outbreaks of infectious diseases will occur. Vector competence can be affected by rearing temperature and inter- and intraspecific competition experienced by the individual mosquito during its larval development. This research investigates whether a new morphological indicator of larval rearing conditions, wing shape, can be used to distinguish reliably temperature and competitive conditions experienced during larval stages. Aedes albopictus (Skuse) and Aedes aegypti (L.) (Diptera: Culicidae) larvae were reared in low intraspecific, high intraspecific, or high …

Seasonal Photoperiods Alter Developmental Time And Mass Of An Invasive Mosquito, Aedes Albopictus (Diptera: Culicidae), Across Its North-South Range In The United States, Steven A. Juliano, Donald A. Yee, Steven M. Vamosi

Faculty Publications – Biological Sciences

The Asian tiger mosquito, Aedes albopictus (Skuse), is perhaps the most successful invasive mosquito species in contemporary history. In the United States, Ae. albopictus has spread from its introduction point in southern Texas to as far north as New Jersey (i.e., a span of approximate to 14 degrees latitude). This species experiences seasonal constraints in activity because of cold temperatures in winter in the northern United States, but is active year-round in the south. We performed a laboratory experiment to examine how life-history traits of Ae. albopictus from four populations (New Jersey [39.4 degrees N], Virginia [38.6 degrees N], North …

Bark Beetles, Ryan S. Davis, Darren Mcavoy

All Current Publications

Bark beetles are one of the most destructive forest pests in the world. They are different than the larger longhorned and roundheaded/metallic woodboring beetles commonly infesting the inner wood of trees. The largest bark beetle, the red turpentine beetle (Dendroctonus valens), reaches only 8.3 mm in length. Because of their tiny size, bark beetles are not effective tree killers as individuals.

Snoqualmia, A New Polydesmid Milliped Genus From The Northwestern United States, With A Description Of Two New Species (Diplopoda, Polydesmida, Polydesmidae), William A. Shear

Insecta Mundi

Snoqualmia, new genus, is described for two species of polydesmid millipeds from the northwestern United States: Snoqualmia snoqualmie, new species, from Washington State, and S. idaho, new species, from Idaho. Males of S. idaho possess unusually complex gonopods, perhaps the most complex to be found in the Order Polydesmida. Snoqualmia is placed in context with other polydesmid genera known from North America. The polydesmid fauna of North America is discussed, as well as characters of the gonopods of the family.
