Species Guides

11

Campiglossa is a of tephritid fruit flies comprising at least 190 described . Species are phytophagous and primarily associated with Asteraceae plants, where they function as seed by damaging inflorescences. The genus has been documented across Asia, Europe, and North America, with specific studies on C. loewiana in the Qinghai-Tibet Plateau and C. snowi in North American of Arnica chamissonis.

Identification

-level identification within Campiglossa requires detailed morphological examination; a key to Iranian species has been published. Larvae, , and pupae are extremely similar in across species, making life-stage identification difficult without molecular methods such as COI .

Habitat

Alpine meadows, marsh meadows, and alpine cold meadows at elevations of 3,492–4,203 m in the Qinghai-Tibet Plateau. Associated with capitulum inflorescences of Asteraceae plants in wild .

Distribution

Documented from China (Qinghai Province, Guoluo Prefecture), Finland (Nylandia, Uusimaa), Germany, Iran (including Fars Province), Denmark, Norway, Sweden, and the United States (Vermont).

Seasonality

of C. loewiana collected July–October in Qinghai Province, China.

Diet

Phytophagous; feeds on Asteraceae plants. C. loewiana damages inflorescences of Aster farreri, A. diplostephioides, A. poliothamnus, and A. souliei. C. snowi consumes seeds of Arnica chamissonis. C. producta has been recorded from Cichorium intybus.

Host Associations

  • Aster farreri - inflorescence damage
  • Aster diplostephioides - inflorescence damage
  • Aster poliothamnus - inflorescence damage
  • Aster souliei - inflorescence damage
  • Arnica chamissonis - seed
  • Cichorium intybus - new record for C. producta

Life Cycle

Holometabolous. , larvae, and pupae are relatively small and exhibit extremely similar morphologies at each stage, making differentiation difficult based on alone.

Behavior

Creates cavities within plant inflorescences, preventing seed formation or maturation. between distant may be facilitated by wind or human activities; high has been observed across geographically separated populations of C. loewiana despite topographical barriers.

Ecological Role

Seed of Asteraceae plants. Reduces seed production in , potentially impacting plant and posing challenges to collection and of native Asteraceae germplasm resources.

Human Relevance

Considered a pest in China due to damage to native Aster of ecological and potential economic importance. Impacts efforts to collect and utilize genetic resources of Asteraceae plants.

More Details

Genetic structure

COI barcode analysis of C. loewiana identified 11 haplotypes across 5 geographic locations in the three-river source region. Strong genetic differentiation exists between Chinese and Finnish , with low , while high gene flow occurs between some distant Chinese populations, suggesting recent population expansion.

Taxonomic scope

This record combines information from multiple within the . Traits described for C. loewiana and C. snowi may not apply to all 190+ described species in Campiglossa.
