Distribution

Trigonogastrella is known only from eastern Australia, where it has been found from Queensland to Victoria and Tasmania.

Hosts

Recorded from Liriomyza brassicae; Liriomyza helichrysi; Ophiomyia solanicola; Phytomyza clematidicolla (Noyes, 2002;2003); Chromatomyia syngenesiae (Bjorksten et al, 2005).

Biology

Known as parasitoids of leafmining Diptera on herbaceous plants.


Comments

This is a fairly common parasitoid of agromyzid leafminers in Australia, however it has not yet been found in Southeast Asia. It might be useful as an imported biological control agent in Asia, and as a native natural enemy if the leafminer gets to Australia.
