Summary: Fluorescent labeling techniques are increasingly used to study the transport of pesticides in crops, and this study investigated the distribution, translocation, and metabolism of imidacloprid in pakchoi using fluorescence microscopy and UPLC-MS/MS. It was found that the translocation rate of imidacloprid-loaded fluorescence nanoparticles was higher under sunlight conditions compared to dark conditions, with different transport routes observed under hydroponic and foliar spray conditions. Additionally, fewer metabolites were produced from the fluorescent nanoparticles compared to conventional imidacloprid granules.

Summary: A photodegradable hydrogel consisting of avidin and biotinylated polyethylene glycol (PEG) was developed for multi-functional matrix suitable for cell culture and sorting. Cells embedded in the hydrogels could be recovered without cell damage, and target cells could be selectively liberated by light-induced hydrogel degradation. The hydrogels are easy to decorate with functional molecules and allow light-guided cell manipulation, making them useful tools in cell engineering and sorting processes.

Summary: FeS@SBA-15 catalyst was successfully synthesized and applied for the degradation of imidacloprid in wastewater through persulfate activation. The catalyst showed high removal efficiency due to the improved dispersion of FeS and abundant surface sites. The system exhibited stable catalytic activity over a wide range of pH, temperature, inorganic ions, and humic acid. The degradation pathways of imidacloprid were identified and the detoxification of formed compounds was analyzed. These findings provide new insights into the application of FeS@SBA-15 catalyst in wastewater treatment and the removal mechanism of imidacloprid.

Summary: An investigation was conducted to characterize the susceptibility of 43 cotton aphid populations to imidacloprid over a 2-year period. The study found variable levels of resistance in the populations, with higher resistance associated with greater cotton production intensity. Rotating modes of action and limiting insecticide use are recommended to delay the evolution of insecticide resistance in cotton aphid populations.

Summary: This study investigated the impact of imidacloprid on tropical freshwaters using acute single species and mesocosm studies in Ethiopia, finding that certain arthropods were sensitive to imidacloprid. The mesocosm experiment showed significant changes in macroinvertebrate and zooplankton community structure in response to repeated imidacloprid exposure. Temperature aquatic taxa were found to be more sensitive to imidacloprid compared to temperate aquatic taxa.

Summary: Micro(nano)plastics are widely present in the environment, with increasing concentrations of imidacloprid (IMI) in intensive agricultural regions drawing attention. The interaction of nanoplastics (polystyrene (PS)) and IMI in vegetable crops has been poorly studied. This research examines the effects of positively (PS-NH2) and negatively (PS-COOH) charged nanoplastics on the uptake, translocation, and degradation of IMI in Chinese flowering cabbage. Results indicate that PS-NH2 inhibits plant growth and reduces IMI translocation, while PS-COOH accelerates IMI accumulation and translocation. Both positively and negatively charged nanoplastics can accumulate in Chinese flowering cabbage, raising concerns about their combined toxicity.

Summary: Flupyradifurone (FPF) is a new type of insecticide that is considered as an alternative to banned neonicotinoids. This study assessed the toxicity of FPF on aquatic arthropod species and compared it with imidacloprid. The results showed that FPF had slower uptake and faster elimination compared to imidacloprid. FPF also had a higher hazardous concentration value and exhibited significant chronic effects on certain aquatic organisms.

Summary: This study assessed the stability of physiological and behavioral resistance in house flies to imidacloprid over time. The results showed significant variation in physiological susceptibility among different house fly strains. However, a house fly strain (BRS-1) selected for behavioral resistance to imidacloprid did not exhibit significant changes in survival rates over 30 generations.

Summary: Optogenetic systems driven by yellow-orange light are required for simultaneous regulation of multiple cellular processes. The red fluorescent protein FusionRed has been engineered into an optogenetic module called degFusionRed, which efficiently performs light-controlled transcription and targeted protein degradation. Unlike other fluorescent protein-based optogenetic domains, degFusionRed undergoes proteasomal degradation upon illumination, avoiding self-inactivation through reactive oxygen species generation. Its spectral compatibility with blue and near-infrared-light-controlled optogenetic tools and autocatalytically formed chromophore provide advantages over exogenous chromophore-dependent optogenetic tools.

Summary: This article introduces a generic Bayesian network model called PRReSTo, which estimates likely infestation rates of host items in consignments. PRReSTo takes into account the vulnerability of host items to pest infestation, the abundance of pests to which host items are exposed, and the effects of risk-reducing measures. PRReSTo can be used to evaluate the effectiveness and acceptability of risk reduction measures in different pest-host systems.

Summary: Invasive tephritid fruit flies pose a significant threat to commercial fruit and vegetable production. Early detection is crucial, and male lures are an important component of trapping networks. This review aims to summarize data on the change in attractiveness of male lures during aging in the field, highlighting studies that relate trap captures to changes in residual content and release rate.

Summary: Colletotrichum and Alternaria species have become emerging fungal pathogens causing severe economic losses in citrus orchards in the Mediterranean area. The use of copper-based antimicrobials for disease management is increasingly problematic, and research for alternative formulations is encouraged. This study tested copper-alternative products on citrus orchards and found that they significantly reduced disease incidence and severity, often showing comparable or better efficacy than copper. The good efficacy of these products suggests their potential for sustainable and large-scale use in integrated and organic citriculture.

Summary: This study updated the economic thresholds for Lygus spp., a major insect pest of canola in Canada, by integrating a large data set collected over 23 years. The results revealed that the economic injury level for Lygus was around 9-23 insects per 10 sweeps, while spraying a foliar insecticide was only necessary when Lygus catches exceeded 30 insects per 10 sweeps. Additionally, analysis of Precision Yield Data showed that at low abundances (under 17 insects per 10 sweeps), Lygus may potentially stimulate canola yield and do not require control action.

Summary: The giant borer, Telchin licus, is a significant pest of sugarcane in Central and South America, and traditional control methods are ineffective due to the larvae's hiding behavior. Recent research has shown that transgenic sugarcane expressing Bacillus thuringiensis proteins, originally developed to control another sugarcane pest, can also effectively control the giant borer.

Summary: A novel methodology was proposed to analyze water-sensitive papers (WSPs) for evaluating spray quality. The segmentation of overlapping droplets based on concave point detection and ellipse fitting achieved high accuracy. A linear relationship between droplet density and coverage was observed, and simulated WSPs were generated for high coverage estimation. This approach allows for more accurate spray quality indicators from WSP collectors.
