Parasitism Of Greenbugs (Homoptera: Aphididae) By Lysiphlebus Testaceipes (Hymenoptera: Braconidae) In Grain Sorghum: Implications For Augmentative Biological Control, Odair A. Fernandes, Robert J. Wright, Z. B. Mayo
Department of Entomology: Faculty Publications
Field cage studies were conducted to describe the relationship between the percentage of Lysiphlebus testaceipes (Cresson) parasitism (as measured by aphid mummies) and densities of greenbug, Schizaphis graminum Rondani, on grain sorghum, Sorghum bicolor L. In 1993 and 1994, a biotype E-susceptible grain sorghum hybrid was grown in field cages and L. testaceipes adults were released after each plant was infested with 20 biotype E greenbugs. The release rates were 0, 0.5, 1.0, and 2.0 wasps per plant in 1993, and 0, 0.16, 0.33, and 0.5 wasps per plant in 1994. Greenbugs and mummies were counted 1-2 times a week …
Effects Of Food Deprivation, Age, Time Of Day, And Gamma Irradiation On Attraction Of Mexican Fruit Flies (Diptera: Tephritidae) To Two Synthetic Lures In A Wind Tunnel, David C. Robacker
Effects Of Food Deprivation, Age, Time Of Day, And Gamma Irradiation On Attraction Of Mexican Fruit Flies (Diptera: Tephritidae) To Two Synthetic Lures In A Wind Tunnel, David C. Robacker
Entomology Papers from Other Sources
The physiological condition of Mexican fruit flies, Anastrepha ludens (Loew), affected their attraction to 2 similar but qualitatively different synthetic lures in wind-tunnel bioassays. The 2 lures were BioLure (ammonium acetate and putrescine) and AMPu (ammonium carbonate, methylamine HCI, and putrescine) . Effects of food deprivation on attraction to the lures were smaller than the effects of sex, time of day, and irradiation. Sugar-fed, protein-starved flies were attracted more strongly than other hunger-status groups to the lures. Sugar-starved, protein-starved females were less responsive than other groups of females to AMPu. Protein-starved males were more responsive than protein-fed males to BioLure. …

The Rediscovery, Taxonomy, And Biology Of Chlosyne Gorgone Gorgone And Chlosyne Ismeria (Nymphalidae) In Burke County, Georgia, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
On April 24, 1993 a colony of Chlosyne gorgone gorgone was found in Orangeburg County, South Carolina, United States. This led to the rediscovery on April 27, 1993 of C. g. gorgone at its type locality in Burke County, Georgia. This species had not been seen or collected anywhere in east coastal Georgia or coastal South Carolina since its description in 1810. The type locality is xeric, scrub oak sandhill. This habitat is generally unsuitable for the survival of later broods. The larvae of nominate gorgone have only been found on Helianthus divaricatus. Topotypical gorgone differ slightly, …

Viral, endoparasitoid and/or host genes that specifically inhibit the immune response of insect pests, useful for broadening the host range of insect viruses. Symbiont viruses of insect pests are genetically modified to express immune-suppressing proteins or biologically active fragments thereof and, optionally toxins, to increase the virus host range and/or improve the efficacy of insect pathogens.
"Insects" From Atlas Of The Sand Hills, Brett C. Ratcliffe
"Insects" From Atlas Of The Sand Hills, Brett C. Ratcliffe
University of Nebraska State Museum: Entomology Papers
Because the Sand Hills are, for the most part, a treeless landscape of grass-covered sand dunes, most of the insects are adapted to sandy habitats and a dry, continental climate, as well as to the kinds of plants and other animals that live there. Unlike most forest-adapted species, insects in the Sand Hills tolerate drier and windier conditions and greater solar radiation. They have also been successful in surviving the periodic fires that are so necessary for maintaining native grasslands. In fact, the mosaic of habitats partially created by fire has probably contributed to increased insect diversity in the Sand …
Beneficial Arthropods Associated With Buffalograss, Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan
Beneficial Arthropods Associated With Buffalograss, Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan
Department of Entomology: Faculty Publications
Beneficial arthropods collected from buffalograss, Buchloe dactyloides (Nuttall) Engelmann, evaluation plots and vegetatively established buffalograss lawns included predatory ants, spiders, ground beetles, rove beetles, big-eyed.bugs, and several species of hymenopterous parasitoids. Ants and spiders were the most abundant beneficial arthropods collected, representing 84% of the total beneficial arthropods captured. Pitfall traps collected >2.5 times as many (16,094) beneficial arthropods as sod plug samples (6,054), demonstrating that pitfall traps are a more effective technique than sod plugs for capturing highly mobile surface-dwelling arthropods. Families of parasitoids captured on sticky traps during the 2-yr sampling period included Scelionidae, Encyrtidae, Mymaridae, and Trichogrammatidae. …
An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle
An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
This paper verifies and expands upon the information presented by dos Passos and Klots in their 1969 systematic revision of Anthocharis midea. Their restriction of the range of A. midea midea to the coastal islands and immediate coast of Georgia and South Carolina, United States is confirmed and expanded north into southern coastal North Carolina. Their range of A. m. annickae is expanded southward from Virginia to central Georgia. A new subspecies, A. midea texana, is described from Texas. Texana is annickae’s ancestor. It differs from annickae only in having greatly reduced black scaling …

Diversity And Dominant Species Of Ground Beetle Assemblages (Coleoptera: Carabidae) In Crop Rotation And Chemical Input Systems For The Northern Great Plains, Michael M. Ellsbury, Janine E. Powell, Frank Forcella, W, David Woodson, Sharon A. Clay, Walter E. Riedell
Agronomy, Horticulture and Plant Science Faculty Publications
Dominant carabid species present in crops and crop rotation sequences commonly used in the northern Great Plains were assessed as an initial step toward the management of carabids as natural control agents. Ground beetle populations were determined by pitfall trapping in 4 crop rotation treatments maintained under high, managed, and low levels of chemical fertilizer and pesticide inputs. Diversity and species richness among crops, rotations, and input levels were compared using 3 indices—the Shannon-Weaver Index, relative diversity, and the Hierarchical Richness Index (HRI). Four carabid species, Cyclotrachelus altemans (Casey), Poecilvs lucublandus Say, Harpalns pensylvanicus (DeGeer), and Bembidion quadrimaculatum L., comprising …

A New Tribe, Genus, And Species Of Limnichid Beetle, Woolridgeus Perforatus, From Malaysia (Coleoptera: Limnichidae: Wooldridgeini), Paul J. Spangler
Insecta Mundi
A new tribe is established in the Limnichidae, Limnichinae, for a new genus and species, Wooldridgeus perforatus, from Sabah, Malaysia. Two autapomorphic characters distinguish Wooldridgeini from the two other tribes of the subfamily Limnichinae; 1) the mesotarsus and metatarsus join their respective tibia ventrally (medially) and preapically instead of the usual apical only connection and 2) a large pore, presumed to be an opening of a prothoracic gland, is present on each hypomeron. Distinguishing characters are illustrated by scanning electron micrographs and line drawings. A key to the three tribes included in the Limnichinae is provided.

Agronomy, Horticulture and Plant Science Faculty Publications
Geostatistical methods were used to characterize spatial variability in western ( Diabrotica virgifera virgifera LeConte) and northern ( Diabrotica barberi Smith & Lawrence) corn rootworm adult emergence patterns. Semivariograms were calculated for adult emergence density of corn rootworm populations in fields of continuous corn and rotated (corn/soybean) corn. Adult emergence densities were generally greater for northern corn rootworms than for western corn rootworms. The spatial structures of the adult rootworm emergence were aggregated as described by spherical spatial models for western corn rootworm and exponential models for northern corn rootworm. Range of spatial dependence varied from 180 to 550 m …
Sp518 Gypsy Moth Management For Homeowners, The University Of Tennessee Agricultural Extension Service
Sp518 Gypsy Moth Management For Homeowners, The University Of Tennessee Agricultural Extension Service
Forestry, Trees, and Timber
Soon, the gypsy moth will become a household word in Tennessee. This obnoxious new neighbor will be eating its way through our hardwood forests, leaving some forests bare.
The gypsy moth is an introduced exotic insect that defoliates hardwood trees, particularly oaks and hickories. Several successive defoliations by the gypsy moth may eventually kill the tree. The gypsy moth has the potential to decimate some older oak forests, similar to the effects of chestnut blight in the early 1900s. The moth was brought to Massachusetts from Europe in 1869 as part of a silk-making experiment. Some larvae escaped, and the …
