• Amauromyza

  Amauromyza is a genus of leaf-miner and stem-borer flies in the family Agromyzidae, comprising over 60 described species. Most species are phytophagous, with larvae feeding internally in plant tissues. The genus includes significant agricultural pests such as Amauromyza karli, which has recently emerged as a major constraint to quinoa production in the western United States. Species exhibit variation in feeding ecology, with some mining leaves and others boring stems.

• Liorhyssus

  scentless plant bugs

  Liorhyssus is a genus of scentless plant bugs in the family Rhopalidae, subfamily Rhopalinae. The genus contains at least 12 described species distributed across multiple continents. The most widely studied species, Liorhyssus hyalinus, has emerged as an agricultural pest of quinoa when the crop is cultivated outside its native Andean region, particularly in coastal Peru. Members of this genus feed on developing seeds and grains using piercing-sucking mouthparts.

• Scrobipalpa

  Scrobipalpa is a genus of small moths in the family Gelechiidae, established by Janse in 1951. The genus contains over 100 described species distributed across Africa, Asia, Europe, and introduced populations in North America and Australasia. Several species are economically significant agricultural pests, particularly of sugar beet, quinoa, tobacco, and eggplant. The genus was historically split with Euscrobipalpa treated as a subgenus or separate genus, but this distinction is no longer recognized as valid.

• Scrobipalpa atriplicella

  goosefoot groundling moth

  Scrobipalpa atriplicella is a small gelechiid moth native to Eurasia, now established as an introduced species in North America. Adults have a wingspan of 10–14 mm and exhibit two generations per year. The species has emerged as a significant agricultural pest on quinoa (Chenopodium quinoa) in both Europe and North America, where larval feeding on seeds and foliage can cause complete crop loss. Originally associated with wild Chenopodiaceae including Chenopodium album and Atriplex species, its host range has expanded to include cultivated crops.
