Compositional analysis and insecticidal activity of Eucalyptus globulus (family: Myrtaceae) essential oil against housefly (Musca domestica)

► E. globulus oil and vapour compositions were analyzed by GC-MS and SPME/GC-MS, respectively ► 1,8-Cineole was the major component in both, and it gets enriched in vapour. ► Insecticidal activity is tested for rarely investigated housefly larvae and pupae. ► Lower LD50 observed in fumigation as compared to contact toxicity assay. ► SEM of the treated larvae depicts extensive damage compared to untreated larvae.
