Currently, results indicate that immature T. absoluta stages are attacked by a parasitoid community spontaneously present in tomato crops in Buenos Aires (Argentina) and in Italy. Especially for the larval stage, the parasitoid wasps Pseudapanteles dignus and Dineulophus phtorimaeae are proven to coexist in the field, and show characteristics that suggest that they could be considered as biocontrol agents against the pest by means of augmentative releases. Field evaluation of effective biological control achieved by P. dignus and/or D. pthorimaeae will assess their compatibility with IPM on tomato, and our assessment of economic feasibility of parasitoid mass rearing.
