Use Of Ethanol-And-Turpentine-Baited Flight Traps To Monitor Pissodes Weevils (Coleoptera: Curculionidae) In Christmas Tree Plantations, L. K. Rieske, K. F. Raffa
The Great Lakes Entomologist
Pissodes nemorensis and Pissodes strobi are major pests of pine production in eastern North America. Ethanol-and-turpentine baited traps were used here to monitor weevil populations in a Scotch pine Christmas tree plantation in Wisconsin. Baited pitfall traps were ineffective in trapping either weevil species. However, baited flight traps at 0.8 and 1.6 m above ground effectively captured flying weevils of both species, 70% of which were P. nemorensis. Females of both species were more attracted than males to the ethanoll turpentine baits. Significantly more female P. nemorensis and total P. nemorensis were trapped at a height of 0.8 m …

Effects Of Nitrogen Fertilization On Monoterpenes Of Jack Pine Seedlings And Weight Gain Of Jack Pine Budworm (Lepidoptera: Tortricidae), Deborah G. Mccullough, Paul D. Swedenborg, Herbert M. Kulman
The Great Lakes Entomologist
Nine-month old jack pine (Pinus banksiana) seedlings were grown in a greenhouse under four nitrogen fertilization regimes. Levels of total nitrogen and five monoterpenes in new foliage were measured. Fertilization resulted in four significantly different levels of foliar nitrogen; means ranged from 1.8-4.5 percent dry weight. Contrary to predictions of resource availability theory, seedlings grown under the highest fertilization regime had higher foliar monoterpene levels than seedlings in the other treatments. Newly molted, sixth-instar female jack pine budworm (Choristoneura pinus pinus [Lepidoptera: Tortricidae]) larvae were allowed to feed for four days on new foliage of the seedlings. …

Solvent Deactivation Of Mimosa Webworm Larval Webbing (Lepidoptera: Plutellidae), Robert C. North, Elwood R. Hart, Lu Mingxian
The Great Lakes Entomologist
Untreated larval webbing of the mimosa webworm, Homadaula anisocentra stimulated oviposition. Six-week-old webbing was as active as two-day-old webbing. Stimulatory activity of webbing was lost after rinsing with highly polar solvents, but not after rinsing with nonpolar solvents. Addition of the polar solvent rinses did not induce activity in other substrates nor restore activity to rinsed webbing. No differences in structure were found in a scanning electron microscope examination of unrinsed webbing and webbing rinsed with solvents of varying polarity.

Seasonal Abundance And Species Diversity Of Adult Tabanidae (Diptera) At Lake Lansing Park-North, Michigan, Jeffrey D. Strickler, Edward D. Walker
The Great Lakes Entomologist
A two year study was undertaken to determine the seasonal abundance and diversity of adult deer flies and horse flies, to compare two methods of sampling (Malaise trap and sweep net), and to estimate attack rates by tabanids on people at Lake Lansing Park-North, Ingham County, Michigan, in 1990 and 1991. Tabanids were sampled using dry ice-baited Malaise traps, and by making over- head sweeps with a standard insect net while hiking a trail. Hybomitra spp. (299 individuals of 9 species) peaked in abundance in mid-May to early June in both years. Chrysops spp. (11,675 individuals of 14 species) and …

Absence Of Behavioral Induction In Oviposition Preference Of Papilio Glaucus (Lepidoptera: Papilionidae), J Mark Scriber
The Great Lakes Entomologist
This study addressed the possible behaviora induction effects of previous exposure to several specific host plants on subsequent host "preference hierarchy" and "specificity" (i.e .. how far down the ranking order a female will go) the most polyphagous swallowtail butterfly in the world, Papilio glaucus (Papilionidae). Multi-choice preference bioassays using individual females in revolving arenas were used to assess one of the potentially most significant non-genetic sources of variation: learned (or induced) oviposition preferences. Results of the 4-choice studies using tulip tree (Liriodendron tulipifera; Magnoliaceae), black cherry (Prunus serotina; Rosaceae), quaking aspen (Populus tremuloides; …

Advanced Biotechnology Tools For Invasive Species Management, Invasive Species Advisory Committee
National Invasive Species Council
Increasingly, genetic tools are being used to detect and solve pressing environmental, social, and health-related challenges. It is clear that investments in technology innovation can be game changing, as advances in biotechnology may provide new methods to protect the nation’s resources from the negative impacts of invasive species. The current toolbox of management options is recognizably insufficient to deal with many of the high-impact species that have been introduced. However, “surrendering” to these species is generally not a viable option from ecological, health, economic, socio-cultural, or political perspectives. Cost-efficient solutions to these “grand invasive species challenges” need to be found. …

Invasive species are defined by the United States government to mean “with regard to a particular ecosystem, a non-native organism whose introduction causes or is likely to cause economic or environmental harm, or harm to human, animal, or plant health” (Executive Order [EO] 13751). The ecosystems to which invasive species are introduced or spread are not delimited by jurisdictional boundaries; they intersect with lands managed by federal, tribal, state, territorial, and county governments, as well as properties under private ownership. For this reason, effective coordination and cooperation across jurisdictions is of paramount importance in the prevention, eradication, and control of …

Entomology Faculty Publications
RNA interference (RNAi) based methods are being developed for pest management. A few products for control of coleopteran pests are expected to be commercialized soon. However, variability in RNAi efficiency among insects is preventing the widespread use of this technology. In this study, we conducted research to identify reasons for variability in RNAi efficiency among thirty-seven (37) insects belonging to five orders. Studies on double-stranded RNA (dsRNA) degradation by dsRNases and processing of labeled dsRNA to siRNA showed that both dsRNA degradation and processing are variable among insects belonging to different orders as well as among different insect species within …

Resistance Stability Of The Secondary Tiller Of 'Caldwell' Wheat After The Primary Culm Was Infested With Virulent Hessian Fly (Diptera: Cecidomyiidae) Larvae, Stanley G. Wellso, Jaime E. Araya
The Great Lakes Entomologist
Secondary tiller resistance of 'Caldwell' wheat, Triticum aestivum, with the H6 gene for larval resistance to Hessian fly, Mayetiola destructor, was maintained, after the primary culm had been previously infested with virulent larvae. Earlier studies showed that a primary culm infested initially with a virulent larva allowed subsequent normally avirulent larvae to survive on that cultivar; however, in our study the resistance of secondary tillers was mainained even though the primary culm was infested earlier with virulent Hessian fly larvae. This gene stability for resistance is important for optimizing wheat yield of those cultivars that possess genes resistant to …

Field Investigations On The American Dog Tick, Dermacentor Variabilis, In Northwest Ohio (Acari: Ixodidae), Kelly M. Micher, C. Lee Rockett
The Great Lakes Entomologist
Ecological investigations on the American dog tick, Dermacentor variabilis, were conducted in two metroparks located in Lucas County, Ohio. Adult tick surveys were conducted in 1989 and 1990. For both years, adult tick activity began in late April, and adult ticks were most abundant from early May to mid-June. Observed activity had ceased by early August, producing a unimodal pattern of activity. Sunny days with temperatures between 24 ° and 32°C were most conducive to adult tick activity, and adult ticks were most abundant on grass trails and in meadows. Using nest boxes inhabited by white-footed mice, immature tick …
