Abstract
MEDIANERO, Enrique; KORYTKOWSKI, Cheslavo A; CAMPO, Carlos and DE LEON, Cesar. Hymenoptera parasitoids associated with Anastrepha (Diptera:Tephritidae) at Cerro Jefe and Altos de Pacora, Panama. Rev. Colomb. Entomol. [online]. 2006, vol.32, n.2, pp.136-139. ISSN 0120-0488.
In order to identify the parasitoids that attack fruit flies of the genus Anastrepha Schiner and to establish the associations between them and their hosts in natural conditions biweekly sampling was conducted from November of 2003 to July of 2005 in Cerro Jefe and Altos de Pacora, Panama. A total of six species of parasitoids was identified: Doryctobracon zeteki (Muesebeck), D. crawfordi (Viereck), D. areolatus (Szépligeti), D. capsicola (Muesebeck), D. auripennis (Muesebeck) and Opius bellus Gahan. Five Anastrepha species bred from five families of plants were parasitizeD. The most abundant parasitoids were D. zeteki which represented 49% of total individuals and D. crawfordi which represented 19.48%. D. areolatus was least abundant with 2.59%. A. serpentina (Wiedemann) and A. anomala Stone were the hosts with the highest number of parasitoids in fruits of Pouteria buenaventurensis (Aubrév.) Pilz and Lacmellea panamensis (Woodson) Markgr. D. capsicola was bred from A. serpentina and A. anomala, and D. auripennis from A. serpentina, all are new host records. A dependent relationship between parasitoid species and Anastrepha species was found (x2 = 80, p < 0.05, gl = 20). Pouteria buenaventurensis is a new host plant record for A. serpentina.
