“…Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), the swede midge, is a significant pest of brassica crops (e.g., cabbage, cauliflower, broccoli, oilseed rape/canola) both in its native Eurasia and as an introduced species in North America (Chen et al, 2011; Hallett & Heal, 2001; Philips et al, 2017). A closely‐related species, Contarinia brassicola (Diptera: Cecidomyiidae), native to North America has recently been described as the cause of canola flower galls on the Canadian Prairies (Campbell et al, 2020; Mori et al, 2019).…”

The larvae of Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), the swede midge, targets the meristem of brassica crops where they induce the formation of galls and disrupt seed and vegetable production. Previously, we examined the salivary gland transcriptome of newly‐hatched first instar larvae as they penetrated the host and initiated gall formation. Here we examine the salivary gland and midgut transcriptome of third instar larvae and provide evidence for cooperative nutrient acquisition beginning with secretion of enzymes and feeding facilitators followed by gastrointestinal digestion. Sucrose, presumably obtained from the phloem, appeared to be a major nutrient source as several α‐glucosidases (sucrases, maltases) and β‐fructofuranosidases (invertases) were identified. Genes encoding β‐fructofuranosidases/invertases were among the most highly expressed in both tissues and represented two distinct gene families that may have originated via horizontal gene transfer from bacteria. The importance of the phloem as a nutrient source is underscored by the expression of genes encoding regucalcin and ARMET (arginine‐rich mutated in early stages of tumor) which interfere with calcium signalling and prevent sieve tube occlusion. Lipids, proteins, and starch appear to serve as a secondary nutrient sources. Genes encoding enzymes involved in the detoxification of glucosinolates (myrosinases, arylsulfatases, and glutathione‐S‐transferases) were expressed indicative of Brassicaceae host specialization. The midgut expressed simple peritrophins and mucins typical of those found in Type II peritrophic matrices, the first such description for a gall midge.

“…Swede midge is now established in Québec, Prince Edward Island, and Nova Scotia, Canada (Hallett and Sears 2013). In the United States of America, swede midge populations were first confirmed in New York State in 2004 (Kikkert et al 2006) and subsequently detected in New Jersey, Connecticut, Massachusetts, Vermont, Ohio, Michigan, Maine, New Hampshire, Illinois, Pennsylvania, and Minnesota (Chen et al 2009;Philips et al 2017;Estes 2018;Fleischer and Di Gioia 2020;Goossen 2020;Sideman and Bryant 2021). In Ontario, swede midge has caused significant yield losses in field and vegetable crops, including losses to canola crops in excess of 50% of the expected yield (Hallett 2017).…”

The swede midge, Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), is invasive to North America, where it was first reported in Ontario, Canada. It is now established in eastern Canada and from eastern Minnesota in the Midwest to the northeastern seaboard of the United States of America. Swede midge is a serious pest of brassicaceous plants, including vegetable and oilseed crops. To ensure its early detection in the Northern Great Plains, a monitoring programme was established using pheromone traps located primarily along the edges of canola fields from North Dakota, United States of America, northwest to the Peace River region, in Alberta and British Columbia, Canada. In North Dakota, 117 trap sites were monitored between 2015 and 2021. In western Canada, monitoring occurred on a small scale from 2006 to 2011, and 521 trap sites were monitored from 2013 to 2021. Swede midge was not detected in canola grown in the Northern Great Plains between 2006 and 2021. Partners in North Dakota and western Canada intend to maintain the monitoring programme to support early detection of swede midge if it does continue to disperse northwestwards. The monitoring programme contributes to outreach activities and fosters farmer and agronomist participation in pest management (i.e., community science) in the Northern Great Plains.

“…The swede midge, Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), is native to Eurasia, and a significant pest of crops in the family Brassicaceae ( Chen et al 2011 ). Since arriving in North America ( Hallett and Heal 2001 ), it has expanded its geographic range to include Eastern Canada, and Northeastern and Midwestern USA ( Chen et al 2011 ; Philips et al 2017 ). In addition to feeding on cultivated crucifers, such as cabbage, cauliflower, broccoli ( Brassica oleraceae L.), and canola ( B. napus L., and B. rapa L.), it is found on a wide range of other Brassicaceae ( Barnes 1946 ; Stokes 1953a , 1953b ; Hallett 2007 ; Chen et al 2009 ).…”

The swede midge, Contarinia nasturtii, is a cecidomyiid fly that feeds specifically on plants within the Brassicaceae. Plants in this family employ a glucosinolate-myrosinase defense system, which can be highly toxic to non-specialist feeders. Feeding by C. nasturtii larvae induces gall formation, which can cause substantial yield losses thus making it a significant agricultural pest. A lack of genomic resources, in particular a reference genome, has limited deciphering the mechanisms underlying glucosinolate tolerance in C. nasturtii, which is of particular importance for managing this species. Here, we present an annotated, scaffolded reference genome of C. nasturtii using linked-read sequencing from a single individual and explore systems involved in glucosinolate detoxification. The C. nasturtii genome is similar in size and annotation completeness to that of the Hessian fly, Mayetiola destructor, but has greater contiguity. Several genes encoding enzymes involved in glucosinolate detoxification in other insect pests, including myrosinases, sulfatases, and glutathione S-transferases, were found, suggesting that C. nasturtii has developed similar strategies for feeding on Brassicaceae. The C. nasturtii genome will, therefore, be integral to continued research on plant-insect interactions in this system and contribute to effective pest management strategies.
