The Gall Associates of Asphondylia poss. swaedicola Kieffer & Jörgensen (Diptera: Cecidomyiidae) on Suaeda divaricata Moq.

Interpretive Summary: Insects that induce deformities called galls on plants can have serious implications on growth and visual appeal. Additionally, gall inducers may be globally invasive with numerous instances where their impacts caused millions of dollars in damage to commercially/environmentally valuable plants. This work focuses on a gall system in Argentina and the parasitic wasps associated with it as well as a summary of all wasp associations for that plant genus globally. This work will be used by ecologists, biocontrol workers, and entomologists.
Technical Abstract: We report on the Asphondylia poss. swaedicola inducing apical stem galls on Suaeda divaricate Moq. in the Monte region of Argentina. The inquiline gelechiid Gnorimoschema sp. is confirmed as an associate of A. swaedicola galls. The following hymenopteran parasitoids are associated with this system: Torymus nr swaedicola (Kieffer & Jörgensen), Aprostocetus sp., Horismenus sp., Bracon (Bracon) sp., Chelonus (Microchelonus) sp., Apanteles sp., Zaeucoila robusta, Goniozus nigrifemur. The 20 genera and 23 species of parasitoid previously known to be associated with Suaeda spp. worldwide and their biologies are discussed.
