Abstract Galls are thought to be induced by insects for protection, yet many gall‐forming experience heavy parasitization. Little is known about how parasitoids locate insects. Quadrastichus mendeli Kim & La Salle (Hymenoptera: Eulophidae) an obligate ectoparasitoid of the larvae Leptocybe invasa Fisher et Eulophidae), which invasive pest in eucalyptus ( Eucalyptus spp., Myrtaceae) plantations. In this study, Q. and L. were used explore parasitoid behavior when locating Our results revealed that host location involved five discrete steps: walking, resting or grooming, antennating, probing stinging. Antennation was most frequent behavior, accounting half total time. Host occurred photophase. Female exhibited a clear circadian rhythm: Almost all behaviors during photophase, peaked at sixth hour light phase. The olfactory response rates volatiles from galls decreased significantly after their antennae detached. However, there no significant difference eyes obscured. provide essential information mechanisms gall parasitoids.
