“…Chavalle et al (2017) showed that 17 of 64 winter wheat cultivars registered for commercial use in Belgium were resistant to wheat midge, including the Aigle, Barok, Bodecor, Boregar, Farandole, Gallixe, Kundera, KWS Smart, Popeye, Lyrik, Reflection, Renan, Rubisko, Sherlock, Sy Epson, Tobak, and Universal cultivars. Other resistant cultivars reported in Europe include the German winter wheat cultivar, Skalmeje (Gaafar et al 2011), and the Scottish winter wheat cultivar, Lear (Chavalle et al 2015b). Sun et al (1998) and Shi et al (2002) concluded that phenolic acid played a significant role in the resistance of Chinese winter wheat cultivars.…”

A global review of orange wheat blossom midge,Sitodiplosis mosellana(Géhin) (Diptera: Cecidomyiidae), and integrated pest management strategies for its management

Orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), is a major economic pest of wheat (Triticum aestivum Linnaeus). Here, we review its general biology, history of global spread, economic impact, and methods available to manage its populations. Outbreaks have been reported across the Northern Hemisphere, including in China, Japan, the European Union, the United Kingdom, the United States of America, and Canada. Predators and parasitoids can help attenuate these outbreaks, but control has relied mainly on use of foliar insecticides. Wheat cultivars with resistance to midge conferred by the Sm1 gene became commercially available in 2010 and increasingly are grown to manage midge populations. Forecasting models have been developed in different countries to predict wheat midge populations in an effort to mitigate the degree of economic damage by supporting wheat cultivar selection and to optimise the timing of insecticide applications in conventional wheat production systems. Conservation of natural enemies, insecticides, resistant cultivars, and models combine to form effective integrated pest management programmes for midge, illustrated for Canada with a decision-making flowchart. Future work is needed to address the likely development of midge biotypes with resistance to the Sm1 gene and insecticides currently in use.

“…The orange wheat blossom midge (OWBM), Sitodiplosis mosellana Géhin (Diptera: Cecidomyiidae), is an economically important pest and has caused serious yield losses in most wheat-growing areas worldwide ( Berzonsky et al 2002 ; Thomas et al 2005 ; Bruce et al 2007 ; Gaafar et al 2011 ; Gong et al 2013 ; Jacquemin et al 2014 ). Larvae feed on young kernels, causing kernel damage, poor seed quality, and lower yield.…”

The orange wheat blossom midge Sitodiplosis mosellana Géhin (Diptera: Cecidomyiidae), an economically important pest, has caused serious yield losses in most wheat-growing areas worldwide in the past half-century. A high-quality chromosome-level genome for S. mosellana was assembled using PacBio long-read, Illumina short-read, and Hi-C sequencing technologies. The final genome assembly was 180.69 Mb, with contig and scaffold N50 sizes of 998.71 Kb and 44.56 Mb, respectively. Hi-C scaffolding reliably anchored four pseudochromosomes, accounting for 99.67% of the assembled genome. In total, 12,269 protein-coding genes were predicted, of which 91% were functionally annotated. Phylogenetic analysis indicated that S. mosellana and its close relative, the swede midge Contarinia nasturtii, diverged about 32.7 million years ago. The S. mosellana genome showed high chromosomal synteny with the genome of Drosophila melanogaster and Anopheles gambiae. The key gene families involved in the detoxification of plant secondary chemistry were analyzed. The high-quality S. mosellana genome data will provide an invaluable resource for research in a broad range of areas, including the biology, ecology, genetics, and evolution of midges, as well as insect–plant interactions and coevolution.

“…OWBM has been recorded as a pest in most temperate wheat-growing areas of the world, but particularly in Europe, North America, West Asia, and the Far East (Duan et al 2013;Lamb et al 1999;Oakley et al 1998). In Europe, outbreaks of the OWBM were observed in recent years in the United Kingdom (Bruce et al 2007;Oakley 1994), France (Flodrops and Taupin 2010), Belgium (Jacquemin et al 2014), and Germany (Basedow and Gillich 1982;Gaafar et al 2011;Wetzel et al 1982).

A saturated SNP linkage map for the orange wheat blossom midge resistance gene Sm1

SNP markers were developed for the OWBM resistance gene Sm1 that will be useful for MAS. The wheat Sm1 region is collinear with an inverted syntenic interval in B. distachyon. Orange wheat blossom midge (OWBM, Sitodiplosis mosellana Géhin) is an important insect pest of wheat (Triticum aestivum) in many growing regions. Sm1 is the only described OWBM resistance gene and is the foundation of managing OWBM through host genetics. Sm1 was previously mapped to wheat chromosome arm 2BS relative to simple sequence repeat (SSR) markers and the dominant, sequence characterized amplified region (SCAR) marker WM1. The objectives of this research were to saturate the Sm1 region with markers, develop improved markers for marker-assisted selection (MAS), and examine the synteny between wheat, Brachypodium distachyon, and rice (Oryza sativa) in the Sm1 region. The present study mapped Sm1 in four populations relative to single nucleotide polymorphisms (SNPs), SSRs, Diversity Array Technology (DArT) markers, single strand conformation polymorphisms (SSCPs), and the SCAR WM1. Numerous high quality SNP assays were designed that mapped near Sm1. BLAST delineated the syntenic intervals in B. distachyon and rice using gene-based SNPs as query sequences. The Sm1 region in wheat was inverted relative to B. distachyon and rice, which suggests a chromosomal rearrangement within the Triticeae lineage. Seven SNPs were tested on a collection of wheat lines known to carry Sm1 and not to carry Sm1. Sm1-flanking SNPs were identified that were useful for predicting the presence or absence of Sm1 based upon haplotype. These SNPs will be a major improvement for MAS of Sm1 in wheat breeding programs.
