This study investigates how salinity stress in tomato plants (Solanum Lycopersicum cv.

Wild bees show local spatial and temporal dynamics in southeastern US blueberry farmscapes.

Wild bee communities are the target of various conservation and ecological restoration programs. Strategic conservation can influence bee communities visiting fields and help mitigate pollinator limitations in fruit production. However, planning compatible conservation strategies and gauging their effectiveness requires understanding how local communities vary across space and time in crops and adjacent semi-natural areas.

Tillage type and sentinel insect species affect the relative prevalence of the entomopathogenic fungus, Metarhizium robertsii, in soil.

Because the use of synthetic agrochemicals is generally not allowed in organic crop production systems, growers rely on natural substances and processes, such as microbial control, to suppress insect pests. Reduced tillage practices are associated with beneficial soil organisms, such as entomopathogenic fungi, that can contribute to the natural control of insect pests. The impacts of management, such as tillage, in a cropping system can affect soil biota in the current season and can also persist over time as legacy effects.

The entomopathogenic fungus isolate ICIPE 7 is being developed as an eco-friendly alternative to chemical acaricides in managing natural tick infestation on livestock. Its impact on tick infestation and tick-borne infections in cattle under natural conditions are yet unclear. We conducted a randomized controlled field trial to assess the safety and effects of Tickoff® (a formulation of isolate ICIPE 7) and the chemical acaricide Triatix® on tick infestation and incidence of and in extensively grazed zebu cattle in coastal Kenya.

Chronic bacterial infections exert metabolic costs in Drosophila melanogaster.

Bacterial infections can substantially impact host metabolic health as a result of the direct and indirect demands of sustaining an immune response and of nutrient piracy by the pathogen itself. Drosophila melanogaster and other insects that survive a sublethal bacterial infection often carry substantial pathogen burdens for the remainder of life. In this study, we asked whether these chronic infections exact metabolic costs for the host, and how these costs scale with the severity of chronic infection.

Isolation and characterization of the midgut microbiota of Aedes albopictus to identify suitable candidates for paratransgenesis.

Aedes albopictus is a widely recognized carrier of various pathogens. Its resilient characteristics enable it to easily spread across diverse climates. The microbiota in the midgut of mosquitoes plays a crucial role in the interactions between the host and pathogens and can either enhance or reduce the ability of the insect to transmit diseases.

Laser scarecrows reduce avian corn-foraging propensity but not bout length in aviary trials.

Background: Behavioral mechanisms underlying avian deterrence by lasers in sweet corn are not known, and we evaluated them in a rigorous aviary experiment. Eighteen flocks of European starlings (Sturnus vulgaris) foraged on sweet corn for several days in control and laser treated plots with ripe sweet corn while data were collected on where birds were distributed and how long birds foraged on corn. In 16 trials, fresh ears were presented on wooden sticks, and in two trials birds foraged on natural corn grown from seed.

Comparing simulated aerial and chemigation insecticide applications to manage western bean cutworm (Lepidoptera: Noctuidae) in corn.

The efficacy of aerial application and chemigation of insecticides is not well explored for western bean cutworm, Striacosta albicosta (Smith), management in corn. In the short term, inadequate application of insecticides can lead to control failures when insect pests are not effectively targeted. In the longer term, exposure to sublethal insecticide concentrations can contribute to the evolution of insecticide resistance.

Interactive effects between yields of Bt and non-Bt corn and planting dates in the southeastern United States.

Transgenic corn (Zea mays L.) expressing insecticidal toxins from Bacillus thuringiensis (Bt) helps to control or suppress injury from a range of target insect pests. This study summarizes the yield benefits of Bt corn from field trials in Georgia, North Carolina, and South Carolina evaluating Bt and non-Bt corn hybrids from 2009 to 2023.

CLIPA protein pairs function as cofactors for prophenoloxidase activation in Anopheles gambiae.

Insect prophenoloxidases (proPO) are activated during immune responses by a proPO activating protease (PAP) in the presence of a high molecular weight cofactor assembled from serine protease homologs (SPH) that lack proteolytic activity. PAPs and the SPHs have a similar architecture, with an amino-terminal clip domain and a carboxyl-terminal protease domain. The SPHs belong to CLIPA subfamily of SP-related proteins.

Harnessing miRNAs: A Novel Approach to Diagnosis and Treatment of Tuberculosis.

Mycobacterium tuberculosis (Mtb) complex, responsible for tuberculosis (TB) infection, continues to be a predominant global cause of mortality due to intricate host-pathogen interactions that affect disease progression. MicroRNAs (miRNAs), essential posttranscriptional regulators, have become pivotal modulators of these relationships. Recent findings indicate that miRNAs actively regulate immunological responses to Mtb complex by modulating autophagy, apoptosis, and immune cell activities.

Double trouble? Quantifying the risk from co-exposure to multiple pathogens in Tenebrio molitor at different CO concentrations.

The insect mass-rearing industry to produce feed and food is expanding rapidly. Insects in production frequently encounter multiple pathogens and environmental stressors simultaneously, which can lead to significant economic losses. Our understanding of the interactions between different stressors remains limited, and existing methods primarily focus on determining overall patterns of additivity, synergism, or antagonism.

Immunogenicity of yellow fever vaccine co-administered with 13-valent pneumococcal conjugate vaccine in rural Gambia: A cluster-randomised trial.

Introduction: Because booster doses of pneumococcal conjugate vaccine (PCV) may be given at a similar time to yellow fever vaccine (YF), it is important to assess the immune response to YF when co-administered with PCV. This has been investigated during a reduced-dose PCV trial in The Gambia.

Methods: In this phase 4, parallel-group, cluster-randomized trial, healthy infants aged 0-10 weeks were randomly allocated to receive either a two-dose schedule of PCV13 with a booster dose co-administered with YF vaccine at age 9 months (1 + 1 co-administration) or YF vaccine administered separately at age 10 months (1 + 1 separate) or the standard three early doses of PCV13 with YF vaccine at age 9 months (3 + 0 separate).
