Spatial And Temporal Dynamics Of Predator-Prey Interactions In Winter Wheat, Katelyn A. Kowles

Theses and Dissertations--Entomology

Aphids (Hemiptera: Aphididae) are pests of multiple cropping systems, primarily due to the viruses they vector and direct crop damage that is exacerbated by their rapid population growth. In Kentucky, grain aphids (Rhopalosiphum padi and Sitobion avenae) cause significant yield loss to winter wheat as vectors of Barley Yellow Dwarf virus (BYDV), prompting the routine application of insecticides. Coupled with increasing human populations and decreasing arable land, it is increasingly evident that biological control services provided by natural enemies represent a viable long-term management option. Aphids are preyed upon by a diverse array of predators that can be …

A Comprehensive Understanding Of Corpse Management In Termites, Qian Sun

Theses and Dissertations--Entomology

Undertaking behavior is the disposal of dead individuals in social colonies to prevent potential pathogenic attack. This behavioral trait has convergently evolved in social insects (primarily termites, ants, and honeybee), and is considered an essential adaptation to social living. In honey bee and ants, workers recognize dead colony members through the postmortem change of chemical profile, and corpses are usually removed out of nest. However, in termites, little is known about the behavioral pattern, chemical cue or molecular basis. In the eastern subterranean termite, Reticulitermes flavipes, this study investigated undertaking behavior toward corpses of different origins and postmortem times. …

Selective Processing By The L3 Auditory Interneuron In Acheta Domesticus : Juvenile Hormone Iii And Protein Kinase C, Ashley Ranae Lynch

Master's Theses

Juvenile Hormone III (JHIII) is a prolific and essential hormone in insects, controlling many aspects of insect physiology such as egg development, nymphal and larval maturation, diapause and metamorphosis. In female crickets, Acheta domesticus, JHIII increases selectivity in phonotactic behavior, narrowing phonotactic choices for Syllable Periods (SPs) of the Calling Songs (CSs) that most closely resemble the natural call of the male. JHIII has been suggested to work through a pathway that activates the protein kinase C (PKC) molecule. Chelerythrine Chloride (CC) is a potent inhibitor of PKC action. This study analyzes the responses of the L3 auditory interneuron, which …

Walnut Husk Fly, Diane Alston, Marion Murray, James Barnhill

All Current Publications

Walnut husk fly (Order Diptera, Family Tephritidae; Fig. 1) is the most common insect pest of walnuts in Utah. Husk fly larvae (maggots) tunnel in walnut husks, causing them to soften and decay, and stain the shell (Fig. 2). Damaged husks are difficult to remove. If husk fly infestation occurs early in kernel development, nuts may shrivel, darken, become moldy, and drop from the tree (Fig. 3).

Prehistoric Earth Oven Facilities And The Pathoecology Of Chagas Disease In The Lower Pecos Canyonlands, Karl Reinhard, Adauto Araujo

School of Natural Resources: Faculty Publications

Understanding the endemic region of a disease is part of developing a concept of the disease’s natural history and its threat to human health in both ancient and modern times. Chagas disease is caused by the parasite Trypanosoma cruzi and has recently been identified as an emergent disease in North America. Ancient endemicity and reemergence has been demonstrated by an examination of a mummy found on the border between Coahuila, Mexico and Texas, USA. This mummified man, who died over 1000 years ago, exhibits the gross pathology of megacolon, which is consistent with Chagas disease. We are now exploring the …

The Trichoptera Of Panama I. New Records For Caddisflies (Insecta: Trichoptera) From The Republic Of Panama, Brian J. Armitage, Steven C. Harris, Ralph W. Holzenthal

Insecta Mundi

The Republic of Panama currently has 245 recorded species of Trichoptera distributed among 13 families. Herein we add 32 new country records for Panama, including one new family (Limnephilidae) and one new genus (Limnephilus). We also provide the first collection information for Oxyethira maya Denning for Panama. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate that country’s major cuencas (water basins).

Description Of A New Species Of Plesioclytus Giesbert (Coleoptera: Cerambycidae: Cerambycinae) From Georgia, And Transfer Of The Genus To Plesioclytini Wappes And Skelley, New Tribe, James E. Wappes, Paul E. Skelley

Insecta Mundi

Plesioclytus morrisi Wappes and Skelley new species (Coleoptera: Cerambycidae) from the Ohoopee dune system in central Georgia is described with comments on the biology of the new species. The taxonomic placement of Plesioclytus Giesbert in the tribe Clytini is questioned as key characters are found to differ from the current characters used to define the tribe in the New World, resulting in its transfer to the newly erected Plesioclytini Wappes and Skelley new tribe, defined herein. Habitat photos for the new species and habitus photos for it and P. relictus Giesbert are provided.

The Enigmatic Milliped Genus Pandirodesmus Silvestri 1932 And Description Of A New Species From Tobago Represented By Males (Polydesmida: Leptodesmidea: Chelodesmidae: Chelodesminae: Pandirodesmini), Rowland M. Shelley, Jamie M. Smith

Insecta Mundi

Pandirodesmus rutherfordi, n. sp., represented by 18 individuals including eight adult males, occurs in secondary forests near Charlotteville and Speyside, Tobago, Trinidad and Tobago. Along with the type and second species, P. disparipes Silvestri, from Guyana and known only from females, the segmental legs of P. rutherfordi alternate between long (anterior pairs) and short (posterior ones), spiracular openings are on straw-like tubules, and ozopores are located on paramedian metatergal spines. These features appear to be adaptations for biotopes of loose sand, detritus, or frass, and 17 specimens, including the six juveniles, exhibit coatings of “sand grains” that are loosely …

Scale Insects (Hemiptera: Coccoidea) Found On Dracaena And Ficus Plants (Asparagales: Asparagaceae, Rosales: Moraceae) From Southeastern Asia, Soo-Jung Suh, Khanxay Bombay

Insecta Mundi

A collaborative survey of the scale insects (Hemiptera: Coccoidea) found on dracaena and ficus plants in Cambodia, Laos, Thailand and Vietnam conducted in 2015 identified 49 species of scale insects belonging to 36 genera in six families (25 species on dracaena, 42 species on ficus). Of the species of scale insects that have been reported on dracaena and ficus plants in southeastern Asia in the ScaleNet database (Ben-Dov et al. 2015), 32% and 17% were species collected in this survey, respectively. Twenty-three species (47%) of scale insects have been intercepted at Korean ports of entry on imported dracaena and ficus …

Nueva Especie De Lycomedes Brème, 1844 (Coleoptera: Melolonthidae: Dynastinae) De Los Andes Colombianos Y Clave Para Identifi Cación De Las Especies, Luis Carlos Pardo- Locarno, Alfonso Villalobos Moreno, Román Stechauner Rohringer

Insecta Mundi

A new scarab species of the genus Lycomedes Brème, 1844 is described, totaling five species of the genus reported for Colombia. Lycomedes salazari was collected in an oak forest at the high Andean region of Santurbán in the municipality of California, Santander Department, Colombia. Besides inhabiting the highest altitude known for the genus, L. salazari has affi nities with L. buckleyi Waterhouse, 1880, but differs on the cephalic, thoracic and leg morphologies. Biological notes and an updated key for the adults of the genus are included.
