Population fluctuations of Anastrepha ludens (Loew) and of its natural enemies on Sargentia greggii S. Watts


, : Population fluctuations of Anastrepha ludens (Loew) and of its natural enemies on Sargentia greggii S. Watts. Folia Entomologica Mexicana (41): 49-60

The results are presented of studies carried out in Nueva Leon, Mexico, to investigate the degree of parasitism of Anastrepha ludens (Lw.) on Sargentia greggii, a wild rutaceous tree producing fruits that are infested by the fly. The parasite species found were Doryctobracon crawfordi (Vier.), which was by far the most abundant, and 2 unidentified species of Opius.
