Estimating Parasitism Of Colorado Potato Beetle Eggs, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), By Edovum Puttleri (Hymenoptera: Eulophidae), E. Groden, F. A. Drummond, R. A. Casagrande, J. H. Lashomb 2017 University of Maine

Estimating Parasitism Of Colorado Potato Beetle Eggs, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), By Edovum Puttleri (Hymenoptera: Eulophidae), E. Groden, F. A. Drummond, R. A. Casagrande, J. H. Lashomb

The Great Lakes Entomologist

A computer simulation was used to evaluate methods for estimating parasitism of Colorado potato beetle egg mass populations by Edovum puttleri. The algorithm incorporated the specific attack behavior of E. puttleri, and a development time for parasitized egg masses of ca. 2.9 times that of healthy egg masses. Of the methods compared, a modification of Southwood's graphical technique was found to be most accurate in relation to the true parasitism derived from the algorithm. A regression equation is presented to correct the error in this method at high levels of parasitism. A second simulation was used to test ...


Trimerotropis Huroniana (Orthoptera: Acrididae), A New Record For Wisconsin, Harvey E. Ballard Jr. 2017 The Nature Conservancy

Trimerotropis Huroniana (Orthoptera: Acrididae), A New Record For Wisconsin, Harvey E. Ballard Jr.

The Great Lakes Entomologist

(excerpt)

Trimerotropis huroniana Walker (Subfamily Oedipodinae), is a distinctive species first described by Walker (1902) from a small area of open dunes near Southampton, Ontario. Studies by Cantrall (1968), Hubbell (1929) and Otte (1984) have suggested that T. huroniana is endemic to the sand dune communities of the northern Great Lakes region.

Late Lilac, Syringa Villosa: New Host Of The Lace Bug Leptoypha Mutica (Heteroptera: Tingidae), A. G. Wheeler Jr. 2017 Pennsylvania Department of Agriculture

Late Lilac, Syringa Villosa: New Host Of The Lace Bug Leptoypha Mutica (Heteroptera: Tingidae), A. G. Wheeler Jr.

The Great Lakes Entomologist

The lace bug Leptoypha mutica, a specialist on trees and shrubs of the Oleaceae, feeds mainly on ash, Fraxinus spp., and fringetree, Chionanthus virginicus. In July 1987 and 1988, nymphs and adults were observed on late lilac, Syringa villosa, in a landscape planting in northwestern Pennsylvania. Infested leaves showed chlorotic blotches, the damage concentrated around midribs and lateral veins. This is the first report of lilac serving as a host for a North American tingid.

Bacteria As Ovipositional Attractants For Aedes Aegypti (Diptera: Culicidae), Dana Hasselschwert, C. Lee Rockett 2017 Bowling Green State University

Bacteria As Ovipositional Attractants For Aedes Aegypti (Diptera: Culicidae), Dana Hasselschwert, C. Lee Rockett

The Great Lakes Entomologist

The effectiveness of selected bacterial species as ovipositional attractants for Aedes aegypti was compared. Bacterial washes, in glass containers, were utilized as ovipositional substrates and subsequent egg counts determined the degree of ovipositional attractiveness. Among others, Bacillus cereus and Pseudomonas aeruginosa were noted as being effective attractants. It was concluded that A. aegypti displays discriminatory behavior in selecting individual bacterial species for oviposition.

Attraction Of Acorn-Infesting Cydia Latiferreana (Lepidoptera: Tortricidae) To Pheromone-Baited Traps, J. W. Peacock, S. L. Wright, J. R. Galford 2017 USDA Forest Service

Attraction Of Acorn-Infesting Cydia Latiferreana (Lepidoptera: Tortricidae) To Pheromone-Baited Traps, J. W. Peacock, S. L. Wright, J. R. Galford

The Great Lakes Entomologist

Males of acorn-infesting Cydia latiferreana are attracted to an equilibrium mixture of the four isomers of 8, 10-dodecadien-l-ol acetate, the virgin female-produced pheromone. Trap height relative to the height of trees in which traps are placed seems to be a significant factor influencing moth catches at attractant-baited traps. In an oak woodlot and in an oak nursery, catches of male moths were greater in traps placed near the upper periphery of the canopy than at traps deployed at lower levels in the tree. Practical application of pheromone-baited traps in a forest situation will require further study on lure formulation and ...

Pheromone Lures To Monitor Sparse Populations Of Spruce Budworm, Choristoneura Fumiferana (Lepidoptera: Tortricidae), David G. Grimble 2017 University of Maine

Pheromone Lures To Monitor Sparse Populations Of Spruce Budworm, Choristoneura Fumiferana (Lepidoptera: Tortricidae), David G. Grimble

The Great Lakes Entomologist

Four types of spruce budworm pheromone lures were field-tested in sparse spruce budworm populations in Maine. BioLures® with constant pheromone emission rates less than 1.0, ca. 1.0-1.5, and ca. 15.0 micrograms of pheromone per day were compared to polyvinyl chloride (PVC) lures with rapidly decreasing pheromone emission rates. Mean trap catch was roughly proportional to lure emission rates. All lures continued to catch moths over the entire flight period but moth catches with the three lowest emission-rate lures were judged to be too low. BioLures with the highest emission rate (15.0 micrograms of pheromone per ...

Posters-at-the-Capitol

Farming practices such as no tillage and plowing can institute change on soil physical and chemical characteristics. In this research, the effects of long-term conventional and no-tillage systems on the selected soil properties were determined in a continuous corn system on a farm with Maury silt loam soil. These samples were taken from University of Kentucky's Research Farm (Spindletop Farm). The field used was tilled in 1969 from bluegrass sod and the first time research was conduced was in 1970. Each plot is 20 ft. by 40 ft. and for many years each plot was split with winter cover ...


Social Effects On Vocal Ontogeny In An Ungulate, The Goat, Capra Hircus, Elodie F. Briefer, Alan G. McElligott 2017 Queen Mary University of London

Social Effects On Vocal Ontogeny In An Ungulate, The Goat, Capra Hircus, Elodie F. Briefer, Alan G. Mcelligott

Alan G. McElligott, Ph.D.

Vocal plasticity is the ability of an individual to modify its vocalizations according to its environment. Humans benefit from an extreme form of vocal plasticity, allowing us to produce a wide range of sounds. This capacity to modify sounds has been shown in three bird orders and in a few nonhuman mammal species, all characterized by complex vocal communication systems. In other mammals, there is no evidence for a social impact on vocal development. We investigated whether contact calls were affected by social environment and kinship during early ontogeny in goats, a highly vocal and social species. To test the ...


The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. McElligott 2017 Queen Mary University of London

The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott

Alan G. McElligott, Ph.D.

The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The ...

Elizabeth L. Stegemoller

Background When performing two tasks at once, a dual task, performance on one or both tasks typically suffers. People with Parkinson’s disease (PD) usually experience larger dual task decrements on motor tasks than healthy older adults (HOA). Our objective was to investigate the decrements in cycling caused by performing cognitive tasks with a range of difficulty in people with PD and HOAs. Methods Twenty-eight participants with Parkinson’s disease and 20 healthy older adults completed a baseline cycling task with no secondary tasks and then completed dual task cycling while performing 12 tasks from six cognitive domains representing a ...

Lessons And Challenges Of Trials Involving Ancillary Therapies For Parkinson’S Disease, Chris J. Hass, Elizabeth L. Stegemoller, Madeleine E. Hackney, Joe R. Nocera

Elizabeth L. Stegemoller

Progressive impairment, particularly related to gait, postural control and cognitive decline, are not effectively treated by the current pharmacological and surgical management of Parkinson's disease (PD). This has led many patients and treating physicians to explore concomitant therapeutic modalities such as aerobic exercise, resistance training, physical therapy, massage, dance and music therapy, tai chi and others to aid in reducing symptomatology and improving patient quality of life.
