The efficacy of 37 insecticide treatments against adult Halyomorpha halys (Stål) was established based on exposure to 18-h old dry insecticide residue in laboratory bioassays. Individual adult H. halys were exposed to an insecticide residue for 4.5 h and then monitored daily for survivorship over a 7-d period. The proportion of dead and moribund insects was(More)
BACKGROUND The primary threat from Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) originates from populations continuously dispersing from and among wild and cultivated hosts, so many individuals may not be directly sprayed with insecticides. Limited information exists regarding field-based residual activity of insecticides for management of H. halys in(More)
Halyomorpha halys (Stål), the brown marmorated stink bug, is an invasive, polyphagous insect that causes serious economic injury in particular to specialty crops in the United States. Growers have been forced to respond by increasing the frequency of broad-spectrum insecticide (e.g., neonicotinoid, pyrethroid, and carbamate) applications. One strategy to(More)
We evaluated the effectiveness of three cyanoacrylate glues (trade names: Krazy [Elmer's Products Inc., Westerville, OH], Loctite [Henkel Corporation, Rocky Hill, CT], and FSA [Barnes Distribution, Cleveland, OH]) to attach harmonic radar tags securely on adult Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) and quantified the effect of the radar tag(More)
Native to China, Japan, Korea, and Taiwan, the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) was first detected in the United States in the mid-1990s. Since establishing in the United States, this invasive species has caused significant economic losses in agriculture and created major nuisance problems for home and business(More)
Twenty eight insecticides were evaluated in the laboratory to characterize the impact of specific compounds on locomotory behavior and mobility of adult Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). Horizontal distance and angular velocity were measured for individuals exposed to dry insecticide residue for 4.5 h to evaluate how quickly and intensely(More)
OBJECTIVE The purpose of this study was to show the usefulness of dynamic contrast-enhanced MRI (DCE-MRI) and to determine the optimal time window in MRI for differentiating between septic arthritis and transient synovitis in painful hip joints. MATERIALS AND METHODS Eighteen patients who underwent DCE-MRI were enrolled, and the final diagnoses were(More)
BACKGROUND The purpose of the present study was to compare the clinical results of anterior cruciate ligament reconstruction with use of different grafts in patients with or without excessive joint laxity. METHODS We retrospectively studied eighty-three patients (forty-eight men and thirty-five women) who had undergone anterior cruciate ligament(More)
A recent identification of the two-component aggregation pheromone of the invasive stink bug species, Halyomorpha halys (Stål), in association with a synergist, has greatly improved the ability to accurately monitor the seasonal abundance and distribution of this destructive pest. We evaluated the attraction of H. halys to black pyramid traps baited with(More)
The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a highly polyphagous and mobile pest causing crop damage aggregated at the perimeters of crop fields. Understanding the dispersal biology of H. halys is critical for the development of reliable monitoring and management strategies. In this study, dispersal(More)
