NATIVE PARASITOIDS ASSOCIATED WITH THE GENUS ANASTREPHA (DIPT, TEPHRITIDAE) IN LOS-TUXTLAS, VERACRUZ, MEXICO

In this paper we record the native parasitoids associated with Anastre pha fruit flies collected in a native tropical community from Los Tuxt las, Veracruz, Mexico. A total of 1600 puparia of Anastrepha were reco vered from infested fruits of ten different host plants. From these pu paria we obtained 218 Hymenopteran parasitoids representing the follow ing species: Doryctobracon areolatus (Szepligeti), Utetes (Bracanastre pha) aff. ananstrephae (Viereck), Doryctobracon crawfordi (Viereck), O pius hirtus (Fischer), Microcrasis n, sp., Nealiolus n. sp. (all Braco nidae) ; Odontosema n. sp. and Lopheucoila sp, (Cynipidae). The most a bundant and frequently encountered parasitoid species observed during this study was D. areolatus, representing 59.2 % of all recovered para sitoids. The analysis of different infestation rates in fruits regardi ng to degree of parasitization in these Anastrepha species suggest the y are not cell-elated, meanwhile some host plant characteristics such as fruit size, could play an important role in influencing rates of pa rasitization.
