Summary: The study evaluated the efficacy of different disinfectants, including a prototype, against GII.4 HuNoV using IMS/qRT-PCR assay, with the prototype showing the highest average log reduction. The IMS/RT-qPCR assay proved to be an effective method for assessing disinfectant activities against GII.4 HuNoV in vitro, although further research is needed to improve the virucidal activity of the prototype against more resistant strains.

Summary: The invasive spotted-wing drosophila, Drosophila suzukii, is a major pest of berries worldwide, leading to economic losses and increased production costs. Different types of insecticides are used in conventional and organic fields, but the adoption of more selective insecticides is limited by their lower residual activity and specific requirements for effectiveness. A study on the use of feeding stimulants to improve the efficacy of insecticides against D. suzukii showed mixed results in laboratory assays and limited effects in field conditions. The findings have implications for managing this pest in fruit crops to ensure marketable fruit harvest.

Summary: This study investigates the effectiveness of a novel attract-and-kill tactic, ACTTRA SWD, to manage the invasive spotted-wing drosophila in fruit crops in the continental United States. The results show that background odors in crop fields, particularly odors from host fruits, negatively affect the efficacy of the attract-and-kill formulation. The study also reveals that the physiological status of the fruit fly, including sex, age, and mating status, as well as fruit ripeness, impact its response to the ACTTRA SWD formulation.

Summary: The spotted wing drosophila is an invasive pest that threatens small fruit production in Europe. Control with synthetic insecticides is not recommended due to the risk of pesticide residue. Essential oils, specifically geranium, Scots pine, and dill, show potential as environmentally friendly control options with repellent and insecticidal effects.

Summary: The accidental introduction of Euwallacea fornicatus and its fungal symbiont, Fusarium euwallaceae, into multiple countries has had a devastating impact on economically and ornamentally important tree species. Currently, there is no effective control measure in place to manage this beetle pest. Preliminary tests of commercialized entomopathogenic products showed limited efficacy against the beetle.

Summary: This study compared the efficacy of commercially available leptospiral vaccines for dogs against leptospirosis. The findings showed that vaccinated dogs had a reduced risk of developing clinical disease and renal carrier state compared to unvaccinated dogs. The study demonstrated that commercially available vaccines can provide overall protection of 84% against clinical disease and 88% against renal carrier status. However, the effectiveness of the vaccines varied for different serovars, and this inconsistency is mainly attributed to methodological difficulties in inducing experimental infection using certain serovars. The study also showed that the immunity provided by the vaccines can persist for at least one year under experimental conditions, but the duration of MAT titers induced by vaccination does not correlate with protection.

Summary: This study presents a promising approach of encapsulating pesticides within nanoparticles for sustainable agriculture. The encapsulation efficiency, nanoparticle yield, and particle size of the CS-LC nanoparticles were determined under optimal conditions. The nanoparticles showed high efficacy against Drosophila suzukii, surpassing the commercial product. The encapsulation of chemical pesticides within biodegradable polymeric nanoparticles could establish a sustainable IPM strategy.

Summary: The combination of EF fumigation and cold-temperature treatment is effective for controlling D. suzukii. Cold treatment after EF fumigation showed the best synergistic effect. The concentration of fumigant during treatment also significantly affected the insecticidal activity of the combination treatment.

Summary: This paper presents a configurable dynamic model that simulates the behavior of a Low Voltage (LV) connected off-the-shelf PV inverter during grid disturbances. The model has been validated against empirical characterization of a real inverter and tested at the Power Networks Demonstration Centre (PNDC) using a Real Time Digital Simulator (RTDS). Further simulations aim to reflect the behavior of a distribution network dominated by inverter connected generation under various fault scenarios.

Summary: Drosophila suzukii Matsumura, a significant pest in soft fruits, lays eggs in fruits before harvest, resulting in decay. Field trials were conducted to test alternative pest control options, and it was found that diatomaceous earth combined with a wetting agent based on orange oil/alcohol ethoxylate had the most promising effect. Additionally, combinations of Ca(OH)(2) and gum arabic with polyetherdimethylsiloxanes also significantly reduced oviposition.

Summary: Control of spotted-wing Drosophila, Drosophila suzukii, in small fruits mainly relies on biological, cultural, and chemical methods. Research on host plant resistance as a genetic control strategy is still in early stages. In this study, a detached fruit bioassay was used to identify resistance patterns among 25 Vaccinium species and hybrids. Ten species showed strong resistance, including two wild diploids from the fly's native range and species from specific sections. Certain tetraploid and hexaploid blueberry genotypes displayed significant resistance against D. suzukii, preventing egg-laying and larval growth. This suggests the possibility of heritable resistance against this invasive fly species.

Summary: This study developed a vesicular formulation for cutaneous applications containing resveratrol and Tween80. The nanosized vesicles showed good storage stability and were able to protect skin cells from oxidative stress. The formulation represents an easy-to-prepare, reproducible, up-scaled, and efficient means of delivering resveratrol and enhancing its biological activity in vitro.

Summary: In this study, the nematode Steinernema rarum PAM 25 was evaluated for its control potential against Drosophila suzukii. The results showed that S. rarum PAM 25 is pathogenic to D. suzukii, with the most effective temperature and concentration being 14 degrees Celsius and 4,000 IJs/ml, respectively.

Summary: The use of irradiation as a phytosanitary treatment is limited in low oxygen atmospheres due to the potential induction of radioprotective responses. Few studies have investigated the combined effects of high CO2 and low O2 on radiation sensitivity. In this study, larvae of the fly Drosophila suzukii were exposed to various concentrations of low O2 and high CO2 along with radiation doses. The results show that low levels of O2 induce a radioprotective response, but the addition of CO2 reduces this protective response, particularly at lower radiation doses.

Summary: Novel virus-like particles (VLPs) derived from the Drosophila X virus (DXV) were developed and investigated for their ability to deliver dsRNA in vitro and in vivo. The DXV-VLPs, formed by self-assembling polyproteins fused with eGFP or Myc-tag, could efficiently carry dsRNA and protect it from degradation in D. suzukii body fluids. The study demonstrated that DXV-VLPs could induce higher mortality and gene silencing in D. suzukii compared to unprotected dsRNA.
