Summary: Temperature plays a significant role in the development time and survival rate of the wheat curl mite, with higher temperatures resulting in shorter development times and lower survival rates. This study provides valuable insights for the management of laboratory colonies and enhances our understanding of the impact of temperature on the physiology of the wheat curl mite and its implications for global growth and spread.

Summary: WCM is the only known arthropod vector of four wheat viruses, with WSMV being the most important one. Host resistance to WCM and WSMV is limited and there is a need for more diverse sources of resistance. Genome sequencing plays a critical role in characterizing the genetic diversity in WCM and WSMV populations.

Summary: This study determined the current status of the wheat curl mite (WCM) and WCM-transmitted viruses in Colorado, revealing a high rate of virus incidence, genetic diversity of isolates, and novel virus variants. These findings emphasize the need to investigate the impact and role of novel viruses on disease severity.

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: 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 used an RNA-seq approach to investigate the transcriptome variation in wheat after extended feeding by wheat curl mites (WCM) for 10 days. The study identified common and specific transcriptomic variations in WCM resistant and susceptible wheat cultivars, as well as differential gene expressions related to defense and stress response, lipid signaling and membrane integrity, and phytohormone pathways potentially contributing to WCM resistance. These findings provide important insights into the defense mechanisms of wheat against WCM after extended feeding.

Summary: The study identified genes and pathways involved in plant defenses against pathogens, herbivores, and abiotic stress that were differentially expressed in resistant wheat exposed to wheat curl mite herbivory but were unaffected in susceptible wheat.

Summary: The Wheat streak mosaic virus (WSMV) is the most economically important disease of wheat in the Great Plains region of the United States. The specific determinants responsible for this disease are unknown. In this study, different genes encoded by WSMV were expressed in wheat using the Triticum mosaic virus (TriMV) as a vector, and it was found that WSMV genes 6K1, NIa-VPg, NIa-Pro, and CP cause symptoms resembling different stages of wheat streak mosaic disease. Deletion analysis revealed that specific regions of 6K1, NIa-Pro, NIa-VPg, and CP are responsible for these symptoms.

Summary: The study investigated the dispersal strategies of two phytophagous eriophyoid mite species, revealing that wind dispersal is the main mode while phoretic dispersal is rather accidental. Additionally, it was found that the wheat curl mite has a higher dispersal success than the cereal rust mite, contributing to our understanding of the high invasive potential of the former.

Summary: The eriophyid mite vector, Aceria tulipae, can efficiently transmit Allexiviruses from garlic to leek plants in a semipersistent manner, with an acquisition access period of 30 minutes and an inoculation access period of one hour being crucial for successful transmission. Mixed infections by different virus strains were observed, but transovarial transmission of the viruses was not detected.

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 confirms that the major locus conferring resistance to WSMV in wheat, Wsm2, is located in a dynamic genomic region with extensive structural variation. It also identifies 142 candidate genes within the Wsm2 interval and reveals differential gene expression in the resistant variety Snowmass. These findings contribute to our understanding of viral resistance mechanisms in wheat and provide a list of candidate genes for further validation.

Summary: This study evaluated the seed transmission rates of wheat streak mosaic virus in different cultivars and found significant differences between winter and spring wheat. The findings suggest the need for increased testing of seeds prior to international movement and caution against using infected grain as a seed source.

Summary: Dispersal and colonisation are important factors that determine the survival and success of organisms. This study assessed the dispersal and colonisation potential of the wheat curl mite (WCM) and found that its dispersal strategy is not dependent on genetic variation in the parental population, but rather on the collective movement of fertilised females.

Summary: This study aimed to investigate wheat yield losses in northern and central Iraq caused by Wheat streak mosaic virus (WSMV), High Plains wheat mosaic virus (HPWMoV), and Triticum mosaic virus (TriMV). Mite specimens were collected and identified as A. tosichella through morphological characterization and DNA sequencing. The presence of the viruses was confirmed through DAS-ELISA, with WSMV being the most prevalent (99.56%), followed by HPWMoV (79.5%). This study is the first to report the presence of HPWMoV in Eurasia besides Ukraine and the first record of TriMV in Iraq. The presence of A. tosichella and the three vectored-viruses in Iraq provides critical information for reducing wheat yield losses in the country.
