Resumo(s)
Pesticide applications in olive orchards could alter the biological control of parasitoid
Psyttalia concolor Szépligeti (Hymenoptera: Braconidae) on the key pest Bactrocera oleae Rossi
(Diptera: Tephritidae). Psyttalia concolor adults can be contaminated by exposure to spray droplets,
contact with treated surfaces or oral uptake from contaminated food sources. Pesticides impact
both pest and parasitoid populations when they coexist in time and space, as they reduce pest
numbers available for parasitoids and might cause toxic e ects to parasitoids from which they
need to recover. Therefore, the appropriate timing and application of selective chemical treatments
provides the opportunity to incorporate this parasitoid in the IPM of B. oleae. This manuscript
reviews the current literature on lethal and sublethal e ects of insecticides, fungicides, herbicides,
and biopesticides on P. concolor. Insecticides were generally more toxic, particularly organophosphates
and pyrethroids, while herbicides and biopesticides had less e ects on mortality and reproductive
parameters. Some fungicides were quite harmful. Most of the studies were conducted in laboratory
conditions, focused on reproduction as the only sublethal e ect, exclusively considered the e ect
of a single pesticide and persistence was hardly explored. Field studies, currently quite scarce,
are absolutely needed to satisfactorily assess the impact of pesticides on P. concolor
