Interpretive Summary: The Lychee gall midge is a damaging pest in lychee production in southeast Asia and contributes to yield losses in a crop worth hundreds of millions of dollars annually. We describe two new parasitic wasps that attack the gall midge in Taiwan and contribute to the natural control of this pest. This information will be used by biological control workers, entomologists, and those involved in the production of lychee.

Technical Abstract: The lychee gall midge, Litchiomyia chinensis Yang and Luo (Diptera: Cecidomyiidae), invaded Taiwan in 2008. This fly induces blister-galls on the leaves of lychee, Litchi chinensis Sonn (Sapindaceae), and causes significant yield losses. At present, its natural enemy complex is largely undocumented, thus the overall aim of ongoing research is to investigate the natural enemies of L. chinensis in different areas and seasons in Taiwan. We describe two species that parasitize this gall midge: Quadrastichus lasallei, n. sp. and Quadrastichus johnlasallei, n. sp. that demonstrate biocontrol potential of this pest.
