Abstract
Biological and ecological attributes of Tuta absoluta, as well as, some aspects of parasitoid-host
interaction of T. absoluta egg and larval parasitoids in the laboratory and in the field. 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.
