Abstract
The scelionid egg parasite, Telenomus sphingis Ashmead, effectively parasitized Erinnyis ello eggs in cassava, Manihot esculenta Crantz, in the Dominican Republic. In the 1st year of a 2-yr study, T. sphingis responded well to increases in E. ello egg density. A time lag between the beginning of an intense oviposition period of the host and the action of the parasite resulted in larval population increases. During the 2nd year of the study, T. sphingis effectively prevented the increase of large larval populations and no time lag between the action of the parasite and intense oviposition by E. ello was found. Other E. ello natural enemies identified in the study were Apanteles americanus (Hymenoptera: Braconidae), Polistes major, P. crinitus (Hymenoptera: Vespidae) and Bubulcus ibis (Aves: Ardeidae).Keywords
