Summary: This study analyzed small RNA and degradome libraries from Triticum aestivum and found that MITEs (Miniature Inverted-repeat Transposable Elements) may be the origin of some miRNAs, and miRNAs derived from MITEs preferentially target degradation sites with MITE insertions in the 3' UTR regions of transcripts. This regulatory network could have a significant impact on the post-transcriptional control of gene expression.

Summary: This study introgressed the novel wheat powdery mildew and stripe rust resistance genes Pm5V/Yr5V from Dasypyrum villosum and fine mapped them to a narrowed region in 5VS. The results showed that the Pm5V/Yr5V lines have the potential value to facilitate wheat breeding for disease resistance and do not incur a yield penalty in diverse wheat genetic backgrounds.

Summary: The co-existence of WSMV and HPWMoV in winter wheat plants in Ukraine is common, with WSMV having a higher infection rate than HPWMoV. HPWMoV mainly spreads through mixed infection with WSMV. Most wheat varieties are susceptible to WSMV, while less than half are naturally infected with HPWMoV.

Summary: This study successfully delimited the wheat curl mite resistance gene Cmc4 to a 523 kb region and identified a diagnostic marker haplotype for selecting Cmc4 in breeding programs. It helps in breeding wheat varieties resistant to WCM, reducing its damage to wheat yield and transmission of wheat streak mosaic virus.

Summary: Wheat is a crucial cereal crop used in a wide range of traditional and modern processed foods. Ancient varieties have evolved into modern ones, with hexaploid and tetraploid wheat dominating global production. The success of wheat is largely attributed to the viscoelastic properties of its gluten proteins, allowing for a variety of staple food forms in the human diet. This review provides a comprehensive look at the evolution of wheat from domestication to its high-yield cultivation today.

Summary: This study presents the first report on the phylogenetic relationships and chemotype diversity of Fusarium strains in Paraguay. The dominant chemotype of the Fusarium graminearum species complex (FGSC) strains isolated from wheat fields in Paraguay was found to be 15-ADON. The study also identified other Fusarium species, including F. asiaticum, F. meridionale, and F. cortaderiae.

Summary: The study found that carbamates, organophosphates, and pyrethroids treatments can effectively reduce wheat curl mite populations, while seed treatment, mite growth inhibitors, and organic pesticides are less effective. The experiment also indicated that treating plants with sulfur seven days after mite infestation is the most effective method for wheat curl mite management.

Summary: This study investigated changes in wheat resistance to wheat streak mosaic virus (WSMV) at normal and elevated temperatures and their effects on the emission of volatile organic compounds (VOCs) in wheat cultivars. The results showed that VOCs in the leaves of resistant (R) and susceptible (S) cultivars responded differently to WSMV and temperature changes. Several metabolic pathways and compounds were up-regulated in R plants, especially at an earlier time and at elevated temperatures. The lipoxygenase pathway played an important role in increasing vector attractiveness and tolerance to biotic and abiotic stresses. The results emphasize the importance of understanding the synchronized regulation of defense-related VOCs for plant resistance to viruses and heat stress.

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: This study compares the effectiveness of two fallow trapping patterns and finds that internal trapping of fallow land can clean up plots twice as quickly as trapping surrounding the fallow land. Additionally, trapping efficiency is influenced by climatic conditions, with the wet season being more favorable for trapping than the dry season.

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.
