Biological Control of Three Major Cucumber and Pepper Pests: Whiteflies, Thrips, and Spider Mites, in High Plastic Tunnels Using Two Local Phytoseiid Mites.

To enhance food security, food safety, and environmental health, a bio-based integrated pest management (BIPM) strategy was evaluated at two coastal locations in Lebanon as an alternative to toxic pesticide sprays in commercial high-arched plastic tunnels common in many countries. The evaluation occurred during two cucumber and pepper cropping seasons: spring and fall. At each site, two commercial tunnels were used; farmers' conventional practices were applied in one tunnel, while the BIPM approach was followed in the second tunnel.

Importance of Public and Private Partnership Supporting Data Disaggregation to Measure Racial, Sexual Orientation, and Gender Identity Disparities in COVID-19.

The COVID-19 pandemic has exposed shortcomings in the US public health data system infrastructure, including incomplete or disparate processes related to data collection, management, sharing, and analysis. Public health data modernization is critical to ensure health equity is at the core of preparedness and response efforts and policies that prioritize equitable responses to health emergencies. To address the inequitable uptake and distribution of COVID-19 vaccinations in communities most disproportionately impacted by the pandemic, the CDC Foundation's Response Crisis and Preparedness Unit began partnering with community-based organizations in March 2021 to provide education and outreach and facilitate access to vaccines.

A Review of Commercial - and -Based Biopesticides for the Biological Control of Ticks in the USA.

There is a need for the development of sustainable, nonchemical tick management strategies. Mycoacaricide and mycoinsecticide product development worldwide has focused primarily on fungi in the genera (Hypocreales: Cordycipitaceae) and (Hypocreales: Clavicipitaceae). Microbial biopesticides containing entomopathogenic fungi have potential in tick management.

First Report of the Bat Tick Carios kelleyi (Acari: Ixodida: Argasidae) From Vermont, United States.

The soft tick Carios kelleyi (Cooley and Kohls, 1941) is an ectoparasite of bats that can harbor bacteria known to cause disease in humans, such as Rickettsia spp., Bartonella spp., and relapsing fever Borrelia spp.

Biological control of Western flower thrips, using a self-sustaining granular fungal treatment.

Western flower thrips (WFT), is one of the most destructive pests of vegetables, fruits and ornamental crops worldwide, causing extensive damage by direct feeding of the crop and transmitting economically important viruses. Despite the successes of biocontrol agents to control WFT, more efficient and cost-effective ways must be found to encourage grower adoption of integrated pest management. A sustainable fungal treatment was developed to preserve fungal inoculum in potting soil and reduce thrips populations.

Gene diversity explains variation in biological features of insect killing fungus, Beauveria bassiana.

Beauveria bassiana is a species complex whose isolates show considerable natural genetic variability. However, little is known about how this genetic diversity affects the fungus performance. Herein, we characterized the diversity of genes involved in various mechanisms of the infective cycle of 42 isolates that have different growth rates, thermotolerance and virulence.

Evaluation of spray applications of Metarhizium anisopliae, Metarhizium brunneum and Beauveria bassiana against larval winter ticks, Dermacentor albipictus.

Dermacentor albipictus (Acari: Ixodidae), the winter tick, is a one-host tick that parasitizes large ungulates. They can dramatically affect moose, Alces alces (Artiodactyla: Cervidae), causing significant physiological and metabolic stress and mortality among heavily parasitized individuals. Entomopathogenic fungi in the genera Metarhizium (Hypocreales: Clavicipitaceae) and Beauveria (Hypocreales: Cordycipitaceae) are promising tick biological control agents.

Efforts are underway to produce antimicrobial peptides in yellow mealworms (Tenebrio molitor), which can be developed as more effective and safer animal feed additives. In this work, we expressed Bombyx mori (Bm) cecropin-A in mealworms by the infection of transformed entomopathogenic Beauveria bassiana ERL1170. The active domain of Bm cecropin A gene was tagged with a signal sequence of B.

A novel approach: Beauveria bassiana granules applied to nursery soil for management of rice water weevils in paddy fields.

Background: Spraying of entomopathogenic fungi formulated as wettable powders and suspension concentrates based on oils or water has been used for the management of crop pests. However, the use of fungal granules to control paddy field pests has not been fully explored. Herein, several Beauveria bassiana isolates (ERL1170, ERL1578 and ERL836) were produced as granules using a millet-based solid culture.

Transformation of Beauveria bassiana to produce EGFP in Tenebrio molitor for use as animal feed additives.

Efforts are underway to develop more effective and safer animal feed additives. Entomopathogenic fungi can be considered practical expression platforms of functional genes within insects which have been used as animal feed additives. In this work, as a model, the enhanced green fluorescent protein (egfp) gene was expressed in yellow mealworms, Tenebrio molitor by highly infective Beauveria bassiana ERL1170.

Bumblebee venom serine protease increases fungal insecticidal virulence by inducing insect melanization.

Insect-killing (entomopathogenic) fungi have high potential for controlling agriculturally harmful pests. However, their pathogenicity is slow, and this is one reason for their poor acceptance as a fungal insecticide. The expression of bumblebee, Bombus ignitus, venom serine protease (VSP) by Beauveria bassiana (ERL1170) induced melanization of yellow spotted longicorn beetles (Psacothea hilaris) as an over-reactive immune response, and caused substantially earlier mortality in beet armyworm (Spodopetra exigua) larvae when compared to the wild type.

An oil-based formulation of Isaria fumosorosea blastospores for management of greenhouse whitefly Trialeurodes vaporariorum (Homoptera: Aleyrodidae).

Background: To date, emphasis has been placed on studying the virulence of Isaria fumosorosea conidia rather than the virulence of their blastospores. In the present study, a comparison was made of the efficacy of blastospores of I. fumosorosea (SFP-198) versus conidia against greenhouse whitefly (GWF) Trialeurodes vaporarioum nymphs and thermotolerance at 50 °C.

Leukemia and lymphoma.

Leukemia and lymphoma are the most common and third most common pediatric malignancies, respectively, and share cell lineages, but the clinical and imaging manifestations of these malignancies vary substantially. Along with providing pertinent details on classification, epidemiology, and treatment, this article reviews the current roles of imaging in the management of childhood leukemia and lymphoma, with attention to diagnosis, staging, risk stratification, therapy response assessment, and surveillance for disease relapse and adverse effects of therapy. Advances in functional imaging are also discussed to provide insights into future applications of imaging in the management of pediatric patients with leukemia and lymphoma.

Plant oils for improving thermotolerance of Beauveria bassiana.

Conidia of Beauveria bassiana ARSEF-7060 produced in millet amended with plant oils such as sunflower, corn, or cotton seed oil, were exposed to 45 degrees C of wet heat for 90 min. Conidia from millet+corn oil medium had the highest thermotolerance (LT50 (median survival time): 45.7 min).

Effects of culture media on hydrophobicity and thermotolerance of Bb and Ma conidia, with description of a novel surfactant based hydrophobicity assay.

Hypocrealean entomopathogenic fungal conidia are made up of multi-aged groups given their chronological conidiogenesis. Most thermotolerance assays have been conducted using mixed-age conidia. The present work exploited a polysiloxane polyether copolymer (siloxane) (Silwet L-77®) mediated conidial collection method, validated by a hydrophobicity assay.

Production of thermotolerant entomopathogenic fungal conidia on millet grain.

Thermotolerance of entomopathogenic (insect-killing) fungi should be seriously considered before industrialization. This work describes the feasibility of millet grain as a substrate for production of thermotolerant Beauveria bassiana (Bb) GHA and ERL1170 and Metarhizium anisopliae (Ma) ERL1171 and ERL1540 conidia. First, conidial suspensions of the Bb isolates, produced on millet grain in polyethylene bags, were exposed to five temperatures (43-47 °C) at 15-min intervals for up to 120 min (experiment I).

High frequencies of elevated alkaline phosphatase activity and rickets exist in extremely low birth weight infants despite current nutritional support.

Background: Osteopenia and rickets are common among extremely low birth weight infants (ELBW, <1000 g birth weight) despite current practices of vitamin and mineral supplementation. Few data are available evaluating the usual course of markers of mineral status in this population. Our objectives in this study were to determine the relationship between birth weight (BW) and peak serum alkaline phosphatase activity (P-APA) in ELBW infants and evaluate our experience with the diagnosis of rickets in these infants.
