Biological control of Tuta absoluta in Argentina and Italy: evaluation of indigenous insects as natural enemies.

摘要

By means of an international project, Argentinian and Italian researchers are carrying out joint research to study biological and ecological aspects of Tuta absoluta biological control. This paper lists indigenous natural enemies reported for T. absoluta, as well as the current results on T. absoluta egg and larval parasitoids in both countries. Parasitoid species that conformed to different guilds are shown to coexist in cropping conditions, and some show positive characteristics as potential biocontrol agents against T. absoluta by means of augmentative releases. Future laboratory and field evaluations of the efficacy of biological control programmes in Argentina and Italy are proposed.
