Abstract
OVRUSKI, Sergio M. et al. Introduction and laboratory production of Diachasmimorpha tryoni and Diachasmimorpha longicaudata (Hymenoptera: Braconidae) for the biological control of Ceratitis capitata (Diptera: Tephritidae) in Argentina. Rev. Soc. Entomol. Argent. [online]. 2003, vol.62, n.3-4, pp.49-59. ISSN 0373-5680.
The biocontrol agents Diachasmimorpha tryoni (Cameron) and Diachasmimorpha longicaudata (Ashmead), two endoparasitoids of fruit fly larvae, were introduced to Argentina in 1999 with the purpose of renewing the employment of natural enemies against Ceratitis capitata (Wiedemann). For this reason, the general procedure and maintenance of the host and parasitoids rearing in the laboratory are described, and the results of one year insectary production (January-December/2000) of both D. tryoni and D. longicaudata are discussed. Data are presented of the progeny production, offpring sex ratio, host parasitism percentage, and pupal viability per parasitoid rearing cage during 15 generations of D. longicaudata and D. tryoni reared using late third instar larvae of C. capitata. New perspectives are discussed on the establishment of a biological control program for C. capitata and Anastrepha fraterculus (Wiedemann) in Argentina by using parasitoid augmentative releases.
