Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is a pest native to Southeast Asia. In the last few decades, has expanded its range affect all major European and American fruit production regions. SWD highly adaptive insect that able disperse, survive, flourish under of environmental conditions. Infestation by generates both direct indirect economic impacts through yield losses, shorter shelf life infested fruit, increased costs. Fresh...
Host species that can independently maintain a pathogen in host community and contribute to infection other are important targets for disease management. However, the potential of is not fixed over time, an challenge understanding how within- across-season variability maintenance affects persistence longer time scales relevant management (e.g., years). Here, we sought understand causes consequences seasonal dynamics leopard frogs (Rana sphenocephala Rana pipiens) infected with fungal...
Brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a generalist pest that causes serious injury to variety of crops around the world. After first detection in USA, H. became threat growers resulting significant crop damage. Understanding effect temperature on development will help achieve successful control by predicting phenological timing pest. Here, life table parameters (survival, development, reproduction, and daily mortality) were evaluated for New...
Insecticide applications in blueberry production systems play a crucial role the control of Drosophila suzukii populations. Here, quantitative spray deposition patterns were obtained under replicated field experiments during two seasons with three sprayers, i.e. cannon, electrostatic, and air-blast. Seven insecticides tested (at 6 hours using Potter tower) to determine mortality data for adult D. suzukii. Spray used create model simulations insect Model included rates sprayers insecticide as...
Many corals form close associations with a diverse assortment of coral-dwelling fishes and other fauna. As coral reefs around the world are increasingly threatened by mass bleaching events, it is important to understand how these biotic interactions influence corals' susceptibility bleaching. We used dynamic energy budget modeling explore nitrogen excreted fish affects physiological performance host corals. In our model, presence influenced functioning coral-Symbiodiniaceae symbiosis...
The pioneering work of Kermack and McKendrick (1927, 1932, 1933) is now most known for introducing the SIR model, which divides a population into discrete compartments susceptible, infected removed individuals. model archetype widely used compartmental models epidemics. It sometimes forgotten, that introduced as special case more general framework. This framework distinguishes individuals not only by whether they are or removed, but additionally tracks time passed since got infected. Such...
Drosophila suzukii (Matsumura), spotted-wing drosophila, is a major pest in small fruit crops including highbush blueberry. Controlling D. challenging and chemical control the main method to manage populations. Growers have expressed interest using micro-sprinklers as an alternative apply insecticides. The current study aimed evaluate if insecticide applications can be used protect from egg-laying. Modeling was additional tool parameterize relative efficacy on oviposition. Field measurements...
Acquired phototrophs, organisms that obtain their photosynthetic abilities by hosting endosymbionts or stealing plastids from prey, are omnipresent in aquatic ecosystems. This acquisition of metabolism allows for niche expansion, and can therefore influence competition outcomes alleviating shared resources. Here, we test how acquired alters competitive manipulating light availability to control the energetic contribution photosynthesis phototrophs. Using freshwater protists compete bacterial...
Dynamic Energy Budget models relate whole organism processes such as growth, reproduction and mortality to suborganismal metabolic processes. Much of their potential derives from extensions the formalism describe exchange products between organisms or organs within a single organism, for example mutualism corals symbionts. Without model simplification, are at risk becoming parameter-rich hence impractical. One natural simplification is assume that some act on 'fast' timescales relative...
Abstract Coral reefs are increasingly experiencing stressful conditions, such as high temperatures, that cause corals to undergo bleaching, a process where they lose their photosynthetic algal symbionts. Bleaching threatens both corals’ survival and the health of reef ecosystems create. One possible mechanism for resist bleaching is through association with stress-tolerant symbionts, which resistant but may be worse partners in mild conditions. Some have been found associate multiple...
AbstractInfection intensity can dictate disease outcomes but is typically ignored when modeling infection dynamics of microparasites (e.g., bacteria, virus, and fungi). However, for a number pathogens wildlife categorized as microparasites, accounting within-host processes critical predicting population-level responses to pathogen invasion. Here, we develop framework refer reduced-dimension host-parasite integral projection models (reduced IPMs) that use explore how affect the invasion...
Mixotrophic protists combine photosynthesis with the ingestion of prey to thrive in resource-limited conditions ocean. Yet, how they fine-tune resource investments between their two different metabolic strategies remains unclear. Here, we present a modeling framework (Mixotroph Optimal Contributions Heterotrophy and Autotrophy) that predicts optimal (growth-maximizing) carbon nitrogen as function environmental conditions. Our model captures full spectrum trophic modes, which reflect...
Cnidaria, marine invertebrates that include reef-building stony corals, often rely on photosynthetic endosymbionts to obtain the energy they need for growth. Increased temperatures and/or nutrient pollution can disrupt mutualistic properties of symbiosis, leading host mortality. However, precise mechanism by which this dysbiosis occurs is still unclear. Sea anemones, other cnidarians may algal endosymbionts, are used as a model organism coral holobiont understand costs and benefits...
Abstract Drosophila suzukii Matsumura (Diptera: Drosophilidae) is a key pest of soft-skinned fruit such as blackberry and blueberry. Differing seasonal spray regimes are expected to have variable effects on D. populations. Semi-field cage trials were performed at three locations in the United States (Georgia, Oregon, North Carolina) blueberry crops evaluate this hypothesis. Insecticides with different efficacy rates (ZC - zeta-cypermethrin, SPI spinetoram, CYAN cyantraniliprole) applied...
The invasion of Drosophila suzukii , spotted-wing drosophila, across Europe and the US has led to economic losses for berry cherry growers, increased insecticide applications protect fruit from damage. Commercial production relies heavily on unsustainable use conventional toxic insecticides. Non-toxic strategies are necessary alleviate disadvantages non-target impacts insecticides improve Integrated Pest Management (IPM).
