Influence of Ethanol Grade on Captures of Ambrosia Beetles in Tree Fruit Orchards, Ornamental Nurseries, and Lumber Yards.

Ambrosia beetles, particularly invasive species within the tribe Xyleborini, such as (Blandford, 1894), pose significant threats to various ecosystems and managed habitats worldwide. Monitoring these invaders is vital for effective pest management, typically accomplished through ethanol-baited traps. We compared trap efficacy using denatured ethanol versus absolute ethanol in orchards, tree nurseries, and lumber yards in northeastern Ohio, USA, finding that absolute ethanol traps captured significantly more .

Type and duration of water stress influence host selection and colonization by exotic ambrosia beetles (Coleoptera: Curculionidae).

Fungus-farming ambrosia beetles in the tribe Xyleborini tunnel into plants and trees to establish chambers for cultivating their nutritional fungal mutualists and rearing offspring. Some xyleborine ambrosia beetles preferentially infest and perform better in living but weakened trees. Flood stress predisposes horticultural tree crops to infestation, but the impact of drought stress has not been well studied.

Attraction of Myzus persicae (Hemiptera: Aphididae) to Volatiles Emitted From the Entomopathogenic Fungus Beauveria bassiana.

Beauveria bassiana (Balsamo) Vuillemin infects a wide variety of insects, including the green peach aphid, Myzus persicae (Sulzer). Volatiles emitted from B. bassiana can act as semiochemical attractants or repellents, with most responses reported to date resulting in insects avoiding B.

Stability of Nuclear and Mitochondrial Reference Genes in Selected Tissues of the Ambrosia Beetle .

The fungus-farming ambrosia beetle (Blandford) uses a pouch-like structure (i.e., mycangium) to transport spores of its nutritional fungal mutualist.

Electrophysiological and Behavioral Responses of an Ambrosia Beetle to Volatiles of its Nutritional Fungal Symbiont.

Ambrosia beetles (Coleoptera: Scolytinae) cultivate their fungal symbiont within host substrates as the sole source of nutrition on which the larvae and adults must feed. To investigate a possible role for semiochemicals in this interaction, we characterized electrophysiological and behavioral responses of Xylosandrus germanus to volatiles associated with its fungal symbiont Ambrosiella grosmanniae. During still-air walking bioassays, X.

Colonization of Trees by Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) Is Influenced by Duration of Flood Stress.

The ambrosia beetles Xylosandrus germanus (Blandford) and Xylosandrus crassiusculus (Motschulsky) bore into flood-stressed trees to establish colonies, but the influence of flooding duration on colonization is unknown. This relationship was examined by flooding trees for various time periods and evaluating colonization. In one experiment, X.

Effects of chlorantraniliprole residual on Helicoverpa zea in Bt and non-Bt cotton.

Background: Helicoverpa zea is managed with foliar applications of chlorantraniliprole in cotton varieties that do not express the Vip3Aa19 toxin in the US Cotton Belt. Foliar insecticides and Bt could interact to influence larval susceptibility. Therefore, it has been suggested that chlorantraniliprole can be used as a tool for Bt resistance management.

Long-Lasting Insecticide Netting for Protecting Tree Stems from Attack by Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae).

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) are destructive wood-boring insects of horticultural trees. We evaluated long-lasting insecticide netting for protecting stems against ambrosia beetles. Container-grown eastern redbud, , trees were flood-stressed to induce ambrosia beetle attacks, and deltamethrin-treated netting was wrapped from the base of the stem vertically to the branch junction.

Community Mental Health Professionals' Perceptions About Engaging Underserved Populations.

This study explored mental health professionals' perceptions about barriers and facilitators to engaging underserved populations. Responses were coded using an iterative thematic analysis based on grounded theory. Results revealed that many professionals endorsed barriers to engaging ethnic minorities and families receiving social services.

Attraction of Invasive Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) to Ethanol-Treated Tree Bolts.

Ethanol-treated bolts (tree stem sections) have potential as monitoring and pesticide screening tools for ambrosia beetles (Coleoptera: Curculionidae: Scolytinae). Bolts were infused with ethanol by immersing them for at least 24 h. Attacks on ethanol-treated bolts by Xylosandrus species were compared with captures in ethanol-baited traps.

Minimizing Bee (Hymenoptera: Apoidea) Bycatch in Japanese Beetle Traps.

Native and introduced bees were attracted to and captured in commercially available Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), traps baited with floral lure components: geraniol, eugenol, and phenethyl propionate [PEP] in Rhode Island, Ohio, and Tennessee. Studies in Rhode Island showed that Bombus impatiens Cresson (Hymenoptera: Apidae) was significantly more attracted to geraniol alone and as a component in floral lure blends than to either eugenol or PEP alone. Xylocopa virginica (L.

Managing and Adapting Practice: Provider Perceptions of an Evidence-Informed Framework for Delivering Mental Health Services.

This study examined providers' reflections on delivering managing and adapting practice (MAP), an evidence-informed framework that guides decision-making from scientific and client data. Consensual qualitative research methods were used to analyze the reflections of 201 youth mental health providers. Results indicated that providers approached MAP according to their own preferences and particular cases.

Lesion Localization of Poststroke Lateropulsion.

Background and Purpose- Hemispheric stroke studies associating lateropulsion (pusher syndrome) with the location of brain lesions have had mixed results from small, unmatched samples. This study was designed to determine whether lateropulsion localizes to specific brain regions across patients with stroke using a case-control design. Methods- Fifty patients with lateropulsion after stroke were matched with 50 stroke patients without lateropulsion using age, time since onset of stroke, admission motor Functional Independence Measure score, lesion side, and gender.

Trap Tree and Interception Trap Techniques for Management of Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) in Nursery Production.

The majority of wood-boring ambrosia beetles are strongly attracted to ethanol, a behavior which could be exploited for management within ornamental nurseries. A series of experiments was conducted to determine if ethanol-based interception techniques could reduce ambrosia beetle pest pressure. In two experiments, trap trees injected with a high dose of ethanol were positioned either adjacent or 10-15 m from trees injected with a low dose of ethanol (simulating a mildly stressed tree) to determine if the high-dose trap trees could draw beetle attacks away from immediately adjacent stressed nursery trees.

Sinusoidal Transcranial Direct Current Versus Galvanic Vestibular Stimulation for Treatment of Lateropulsion Poststroke.

Objective: To compare the effects of Transcranial Direct Current Stimulation (tDCS) versus Galvanic Vestibular Stimulation (GVS) on Lateropulsion following stroke.

Methods: Patients with Stroke and Burke Lateropulsion Scale (BLS) scores greater than or equal to 2 gave informed consent to receive sinusoidal 1 Hz DC (0-2 mA) anodal stimulation over the affected parietal cortex versus similar GVS with ipsilesional mastoidal anode. Seated haptic center of pressure (COP-X) was measured using an AMTI analog-to-digital forceplate.

Use of Oral Hydration Protocols for Dysphagic Patients Following Stroke.

Purpose: The aim of the study was to describe the use of oral hydration protocols for dysphagic patients following stroke.

Design And Methods: We reviewed inpatient records for patients able to take food and liquids orally within 30 days of an ischemic stroke. Orders were hierarchically defined with three levels of liquid consistency modification (LCM) and six levels of augmented hydration orders (AHOs).

Effect of Dextroamphetamine on Poststroke Motor Recovery: A Randomized Clinical Trial.

Importance: Data from animal models show that the administration of dextroamphetamine combined with task-relevant training facilitates recovery after focal brain injury. Results of clinical trials in patients with stroke have been inconsistent.

Objectives: To collect data important for future studies evaluating the effect of dextroamphetamine combined with physiotherapy for improving poststroke motor recovery and to test the efficacy of the approach.

Symbiont selection via alcohol benefits fungus farming by ambrosia beetles.

Animal-microbe mutualisms are typically maintained by vertical symbiont transmission or partner choice. A third mechanism, screening of high-quality symbionts, has been predicted in theory, but empirical examples are rare. Here we demonstrate that ambrosia beetles rely on ethanol within host trees for promoting gardens of their fungal symbiont and producing offspring.

Residue Age and Attack Pressure Influence Efficacy of Insecticide Treatments Against Ambrosia Beetles (Coleoptera: Curculionidae).

Management of ambrosia beetles in ornamental nurseries relies, in part, on insecticide treatments to prevent beetles from boring into trees. However, data on residual efficacy of commonly used pyrethroid insecticides is needed to gauge the duration that trees are protected during spring when peak beetle pressure occurs. Residual efficacy of bifenthrin and permethrin trunk sprays was examined in field trials which used trees injected with 10% ethanol to ensure host attack pressure.

Case-Control Study of Impairments Associated with Recovery from "Pusher Syndrome" after Stroke: Logistic Regression Analyses.

Background: Comparing cohorts with similar functional and motor status at admission to inpatient rehabilitation may delineate demographics or impairments associated with recovery from lateropulsion, also known as "pusher syndrome," after stroke based on lesion side. The aim of this case-control study was to determine how demographics and severity of stroke impairments at admission to inpatient rehabilitation distinguish patients who recover from lateropulsion from those who do not.

Methods: Patients with admission motor Functional Independence Measure (FIM) scores less than 31 and contralesional lower extremity Fugl-Meyer motor scores less than 19 out of 34 were included.

Flood Stress as a Technique to Assess Preventive Insecticide and Fungicide Treatments for Protecting Trees against Ambrosia Beetles.

Polarity-Dependent Misperception of Subjective Visual Vertical during and after Transcranial Direct Current Stimulation (tDCS).

Pathologic tilt of subjective visual vertical (SVV) frequently has adverse functional consequences for patients with stroke and vestibular disorders. Repetitive transcranial magnetic stimulation (rTMS) of the supramarginal gyrus can produce a transitory tilt on SVV in healthy subjects. However, the effect of transcranial direct current stimulation (tDCS) on SVV has never been systematically studied.

Dalfampridine in chronic sensorimotor deficits after ischemic stroke: A proof of concept study.

Objective: To evaluate the safety and tolerability of dalfampridine extended release (D-ER) in participants with chronic post-ischemic stroke deficits, and to assess for potential drug activity on sensorimotor function.

Methods: Using a double-blind, placebo-controlled, cross-over design, participants were randomized to placebo/D-ER or D-ER/placebo sequences and given D-ER 10 mg or placebo twice daily. Key inclusion criteria were: ischemic stroke ≥ 6 months, Fugl-Meyer Assessment lower extremity motor score ≤ 28, ability to complete Timed 25-Foot Walk (T25FW).
