Summary: We evaluated the potential of two parasitoids as biocontrol agents ofLiriomyza sativaeBlanchardinnortheasternBrazil. The two species werethe koinobiont larval-pupal endoparasitoidPhaedrotoma scabriventrisNixon(Braconidae) and the idiobiont larval endoparasitoidChrysocharis vonones(Walker) (Eulophidae). The biological parameters evaluated were survivorship,parasitism, and host-feeding, at 25 and 30°C. Differences between the specieswere observed at 25°C, but not at 30°C. At 25°C, the total parasitism forP. scabriventris(196.1 ± 17.7) andC.vonones(176.6 ± 7.24) was similar andwith higher values compared to 30°C, 102.5 ± 8.81 and 89.1 ± 5 66 parasitizedlarvae, respectively. However,C. vononesshowed a 3.97 lower survivorship aswell as higher daily parasitism (1.4-fold) and host-feeding means (1.9-fold)than the braconid at 25°C. The results indicate a potential for both naturalenemiestobeusedasbiocontrolagentsofL. sativae. The differences be-tween species detected at 25°C suggest the best conditions for the applicationof each parasitoid.
