AI Article Synopsis

  • Researchers studied how proteins in the saliva of swede midge larvae affect their interactions with host plants like cabbage and canola.
  • They analyzed the larva's salivary gland transcriptome to identify genes responsible for secreted proteins that play roles in establishing the larvae, managing plant hormones, digesting food externally, and avoiding plant defenses.
  • Many of the secreted proteins were unique to the swede midge and part of larger gene families, indicating they might be evolving through natural selection.

Article Abstract

Proteins in saliva of gall-forming insect larvae govern insect-host plant interactions. , the swede midge, is a pest of brassicaceous vegetables (cabbage, cauliflower, broccoli) and canola. We examined the salivary gland (SG) transcriptome of first instar larvae reared on and catalogued genes encoding secreted proteins that may contribute to the initial stages of larval establishment, the synthesis of plant growth hormones, extra-oral digestion and evasion of host defenses. A significant portion of the secreted proteins with unknown functions were unique to and were often members of larger gene families organized in genomic clusters with conservation patterns suggesting that they are undergoing selection.

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.

The canola flower midge, Contarinia brassicola Sinclair (Diptera: Cecidomyiidae), is a newly-described species that induces galls on canola, Brassica napus Linnaeus and Brassica rapa Linnaeus (Brassicaceae). Identification of the sex pheromone of C. brassicola is essential to developing monitoring tools to elucidate the geographic range and hosts of this new pest, and the extent to which it threatens the $30 billion Canadian canola industry.

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.

Insect taxa vary in their phenology across space creating dissimilar patterns of species abundance over time. The role of human disturbances and invasive species in these patterns of temporal dissimilarity (phenological differences) across space, however, remain largely unexplored. To dissect these patterns, we evaluated four common pests and one newly invasive species (Contarinia nasturtii; Swede midge) at 220 time points across 2 years on organic and conventional farms.
