چکیده
t ( s t a ( s a c s t t ( a o a O F c m t a P w 1 i a We surveyed 15 wild and cultivated plant species in earch of fruit fly (Diptera: Tephritidae) parasitoids uring 4 years (1993–1996) in the state of Veracruz, exico. The following species were infested by Anastreha larvae: Spondias purpurea L., S. mombin L., Tairira mexicana Marchand, Mangifera indica L. (all nacardiaceae), Ximenia americana L. (Olacaceae), itrus sinensis L. and Casimiroa edulis Llave & Lex. Rutaceae), Psidium guajava L., P. sartorianum (Berg.), . guineense Sw., Syzygium jambos L., Myrciaria floriunda (West) O. Berg. (all Myrtaceae), Chrysophyllum exicanum (Brandegce) ex. Standley and Calocarpum ammosum L. (Sapotaceae), and Passiflora foetida L. Passifloraceae). Of these, only C. mexicanum, C. eduis, and P. foetida did not harbor parasitoids. We identied 10 native and exotic larval–pupal parasitoid speies (all Hymenoptera): Doryctobracon areolatus Szépligeti), D. crawfordi (Viereck), Utetes (Bracanstrepha) anastrephae (Viereck), and Opius hirtus Fisher) (all Braconidae), Aganaspis pellenaroi Brethes) and Odontosema anastrephae Borgmeier (Euoilidae) (all native species), and Diachasmimorpha ongicaudata (Ashmead) and Aceratoneuromyia inica (Silvestri) (Braconidae and Eulophidae, respecively; both exotic species). We also identified two upal parasitoids: Coptera haywardi (Ogloblin) (Diapridae; native) and Pachycrepoideus vindemiae (Ronani) (Pteromalidae; exotic). Parasitization levels anged between 0.4 and 83.8%. Native, wild plants arbored significantly more parasitoids per fruit than ultivated ones. Interestingly, in P. guajava 2 fly speies and 5 parasitoid species were once identified in a ingle fruit. We found a negative correlation between ruit size and number of parasitoids/fruit. We rank arasitoids based on host breadth (fruit fly species ttacked) and number of plant species visited. We iscuss some general ecological and practical implicaions of our findings (e.g., effect of fruit size on parasitsm, mass-rearing, and augmentative releases of native s exotic parasitoids) and compare our findings with

a t s In the state of Veracruz, Mexico, fruits from 38 sites at various altitudes were collected monthly over a period of 2 years, and the tephritid fruit flies of the genus Anastrepha and associated parasitoids that emerged rom these fruits were identified and counted. Of the 6 species of fruits that contained Anastrepha larvae, 18 species also contained a total of 10 species of Anastrepha par...

This study reports the first occurrence of Coptera haywardi Loiácono as a pupal parasitoid of fruit-infesting Tephritidae in Brazil. We reared this diapriid from fruits of Eugenia uniflora (Surinam cherry) infested by Anastrepha fraterculus (Wiedemann) and/or Anastrepha sororcula Zucchi. We also identified two other species of pupal parasitoids: Pachrycrepoideus vindemmiae Rondani and Spalangia...

Protein, lipid, carbohydrate, and energy contents of three artificial diets (Xal2, Met1, and Met2) used for laboratory-rearing and mass-rearing the Mexican fruit fly, Anastrepha ludens (Loew), for a sterile insect technique program were measured. The larval survival, pupation, pupal weight, adult emergence, sex ratio, and flight capacity of the flies reared on each of these diets were also quan...

Fopius arisanus and Psyttalia fletcheri are egg and larval parasitoids, respectively, of tephritid fruit flies including the melon fly, Bactrocera cucurbitae. We investigated the consequences of parasitization when eggs or larvae of melon flies were exposed to F. arisanus or P. fletcheri alone, or to both in succession. In addition, we evaluated the effect of fruit substrates on host preference...
