B illbugs are weevils (commonly called snout beetles) that belong to the family Curculionidae that commonly infest high-cut turfgrass species. The bluegrass billbug, Sphenophorus parvulus Gyllenhal, is the most frequently encountered billbug in the state of Ohio, while the lesser billbug, S. mimimus, and hunting billbug, S. venatus, are known as occasional(More)
PURPOSE A model of experimental keratomycosis was established that mimics human disease in which the only fungi present are those that are actively growing within the cornea. METHODS Dutch-belted rabbits received a subconjunctival injection of triamcinolone acetonide to one eye. One day later the epithelium was removed from the central cornea and a(More)
The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae:(More)
PURPOSE To study the differences in disease caused by two wild-type strains of Candida albicans in a model of contact lens-facilitated keratitis in rabbits. METHODS Two strains, SC5314 and VE175, were examined. Standardized inocula were placed on the debrided corneal surface of one eye in Dutch belted rabbits and covered with a contact lens. A temporary(More)
Gypsy moth (Lymantria dispar) populations were low this past season across the state, as were populations of eastern tent caterpillar (Malacosoma americanum) and fall webworm (Hyphantria cunea). However, localized damaging infestations of yellow-necked caterpillar (Datana ministra) and bagworm (Thyridopteryx ephemeraeformis) were observed throughout the(More)
Correct identification of white grub species is important in determining management strategies and timing of controls. The raster pattern is the arrangement of bristles and hairs on the underside of the tip of the abdomen. A 10x hand lens is needed to see this pattern on most mature white grubs. A microscope may be necessary to view smaller grubs or the(More)
The alterations in brain content of norepinephrine (NE) and dopamine (DA) were studied in guinea pigs adapted to simulated high altitude (hypobaric hypoxia) equivalent to 5500 meters. The animals were adapted for 46 days over a period of 82 days to a pressure of 375 mm Hg. The animals were then killed and the following brain parts dissected: cerebellum,(More)
