“…In some Eucalyptus species or chemotypes, substances other than eucalyptol have been reported as dominant elements in the essential oil. For example, (-)-spathulenol constituted 32.66% in E. globulus from Algeria [119] and 37.46% in E. camaldulensis [120]. Additionally, α-pinene was found to be present at 30.4% in Eucalyptus grandis Hill, while β-pinene was at 39.4% in E. tereticornis Sm.…”

Biopesticides, alongside the expansive growth of conventional agriculture, emerged as a hopeful avenue for mitigating the environmental impact of synthetic chemicals. Essential oils derived from various plant species are regarded as environmentally friendly and have been suggested by numerous researchers for combating the pest species. However, in addition to their detrimental effects on harmful species, these essential oils exert varying degrees of impact on non-target species with which they share ecological relationships. This review serves the dual purpose of updating data on the use of the essential oils as biopesticides, considering the substantial increase in research output in the recent years. Simultaneously, it aims to provide a focused synthesis on the essential oils currently approved for commercial use as biopesticides, and shedding light on their impact on beneficial pollinator species, which may inadvertently suffer from the application of substances deemed safe by most users.

Eucalyptus globulus essential oil (EGEO) is considered as a potential source of bioactive compounds with significant biological activity. The aim of this study was to analyze the chemical composition of EGEO, in vitro and in situ antimicrobial activity, antibiofilm activity, antioxidant activity, and insecticidal activity. The chemical composition was identified using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The main components of EGEO were 1,8-cineole (63.1%), p-cimene (7.7%), a-pinene (7.3%), and a-limonene (6.9%). Up to 99.2% of monoterpenes were present. The antioxidant potential of essential oil and results indicate that 10 μL of this sample can neutralize 55.44 ± 0.99% of ABTS•+, which is equivalent to 3.22 ± 0.01 TEAC. Antimicrobial activity was determined via two methods: disk diffusion and minimum inhibitory concentration. The best antimicrobial activity was shown against C. albicans (14.00 ± 1.00 mm) and microscopic fungi (11.00 ± 0.00 mm–12.33 ± 0.58 mm). The minimum inhibitory concentration showed the best results against C. tropicalis (MIC 50 2.93 µL/mL, MIC 90 3.17 µL/mL). The antibiofilm activity of EGEO against biofilm-forming P. flourescens was also confirmed in this study. The antimicrobial activity in situ, i.e., in the vapor phase, was significantly stronger than in the contact application. Insecticidal activity was also tested and at concentrations of 100%, 50%, and 25%; the EGEO killed 100% of O. lavaterae individuals. EGEO was comprehensively investigated in this study and information regarding the biological activities and chemical composition of the essential oil of Eucalyptus globulus was expanded.
