Larval parasitoids of agromyzid leaf miner genus Liriomyza in the southern Thailand : species and their host plants

Larval parasitoids of the leaf miner genus Liriomyza were studied in six provinces of southern Thailand, Songkhla, Phatthalung, Nakhon Si Thammarat, Trang, Satun and Pattani, from April 2000- March 2001. Two families of hymenopteran parasitoids, Eulophidae and Braconidae, were found. The eulophid included Asecodes sp. nr. notandus (Sivestri), Cirrospilus ambiguus Hanssan & LaSalle, Hemiptarsenus variconis (Girault), Neochrysocharis formosa (Westwood) and Quadrastichus sp. nr. liriomyzae Hanssan & LaSalle. There was only one braconid species, Opius dissitus (Muesebeck). Among these, A. sp. nr. notandus was found in highest frequency while H. variconis had the widest range of host plants. The parasitoids were found on 14 host plant species. Vigna sesquipedalis was able to be used by all six species of parasitoids. It was also the host plant most often used by the parasitoids in this study.
