TL;DR: Eucalyptus oil was found to be more effective against mosquito larvae at lower concentration as compared to neem oil, and can be utilized in the community in artificial and small temporary water bodies as an eco-friendly vector control measure in the era of increasing resistance to chemical insecticides.
Abstract: Background and Objectives: Plant-based products can provide safe and biodegradable mosquito control agents. The essential oils have a strong odor due to complex secondary metabolites and exhibit lower density than that of water, which renders them suitable to form a thin layer above the water surface. The present study was designed to evaluate the larvicidal, pupicidal activity of Eucalyptus and neem oils against Aedes aegypti and Aedes albopictus. Materials and Methods: We evaluated the activity of commercially available Eucalyptus (Eucalyptus globulus) and neem (Azadirachta indica) oils against larvae and pupae of A. aegypti and A. albopictus for their larvicidal and pupicidal activity, stability in different water types, dependence on volume and surface area of the water body, and residual efficacy. Results: Eucalyptus oil was found to be more effective against larvae and pupae at lower concentrations, i.e., concentration at which 50% is observed (LC50) for larvae and pupae was 93.3 and 144.5 parts per million (ppm) and concentration at which 90% is observed (LC90) was 707.9 and 741.3 ppm, respectively, while for neem oil, LC50 for larvae and pupae was 7852 and 19,054 ppm and LC90 was 10,092 and 19,952 ppm, respectively. The efficacy of Eucalyptus oil depended on surface area rather than volume of water, and the residual efficacy of Eucalyptus oil was up to 8 days. Conclusions: Eucalyptus oil was more effective against mosquito larvae at lower concentration as compared to neem oil. It can, therefore, be utilized in the community in artificial and small temporary water bodies as an eco-friendly vector control measure in the era of increasing resistance to chemical insecticides.

TL;DR: The larvicidal activity of stable aqua nanoemulsions of eucalyptus oil was tested against Aedes aegyptiusing five different concentrations at 100, 90, 80, 70, 60 and 50 ppm (in triplicate).
Abstract: Essential oils extracted from plants provide an efficient and eco-friendly alternate to manage the challenge of mosquito-borne diseases. The use of these oils as larvicidal agents, however, poses the problem of their improper dispersion in larval aquatic habitats. To overcome this, the methodology for the synthesis of Eucalyptus globulus oil nanoemulsions in water was standardised by mixing the oil in water with Tween®-20 in three different ratios (1:1, 1:2 and 1:3) by sonication. On the basis of thermodynamic stability tests, oil emulsions having E. globulus oil and Tween®-20 in 1:2 ratio was found to be the most stable which was characterised using transmission electron microscopy (TEM). The droplets of prepared nanoemulsions were found to have an average size of 40 nm and were spherical in shape. The larvicidal activity of stable aqua nanoemulsions of eucalyptus oil was tested against Aedes aegyptiusing five different concentrations at 100, 90, 80, 70, 60 and 50 ppm (in triplicate). LC50 and LC90 values were found to be 60.30 and 92.20 ppm. Observations revealed that 70 ppm was the most effective concentration, causing 100 % mortality within 24 h.

TL;DR: Results provide scientific support to examination of Eucalyptus EO as an antimicrobial agent in alternative treatment of multiresistant human pathogens of vaginal origin.
Abstract: The antimicrobial potential of commercial essential oil (EO) of Eucalyptus globulus L. was evaluated against six bacterial vaginal isolates (E. coli 1 and E. coli 2, S. aureus 1 and S. aureus 2, P. aeruginosa and P. mirabilis) and two isolates of Candida strains (C. albicans 1 and C. albicans 2). The antimicrobial activity was assessed through double-dilution micro-plate assay to determine the minimum inhibitory (MIC) and minimum bactericidal/fungicidal (МВС/ MFC) concentration. In addition, brine shrimp toxicity assay was performed in order to determine acute toxicity of the examined EO. The isolated strains of pathogens have shown strain specificity to the tested EO. Certain pathogens resistance was noticed toward the tested antibiotic, as well. E. coli isolates showed resistance to the tested antibiotics but did not show resistance against the Eucalyptus EO (E. coli 1 MIC/MBC 12.5/12.5 μL/mL; E. coli 2 MIC/ MBC 25/25 μL/mL). Moreover, the Eucalyptus EO showed effectiveness in application against S. aureus 2 (MIC/MBC 6.25/6.25 μL/mL), and C. albicans 1 strains (MIC/MFC 6.25/6.25 μL/mL). Furthermore, brine shrimp lethality bioassay revealed the Eucalyptus oil toxicity at an LC50 value of 2.66 mg/mL. The chemical composition of the separated essential oil was analyzed by gas chromatography combined with mass spectrometry (GC-MS) showing eucalyptol (59.63%), p-cymene (15.55%) and DL-limonene (14.90%) as dominant constituents. Although a number of toxicology trials are needed, these results provide scientific support to examination of Eucalyptus EO as an antimicrobial agent in alternative treatment of multiresistant human pathogens of vaginal origin.

TL;DR: It is demonstrated that among the treated oils, eucalyptus oil has higher contact, fumigant and repellent toxicity and hence it can be harnessed for integrated management of S. oryzae under storage condition.
Abstract: Contact, fumigant, persistence toxicities and repellant activity of three plant essential oils viz., cinnamon (Cinnamomum verum J. Presl), eucalyptus (Eucalyptus obliqua L'Her) and orange oil (Citrus sinensis L.) against rice weevil, Sitophilus oryzae L. were evaluated under laboratory condition. Chemical profiling of tested essential oils through GC-MS studies showed presence of various chemical constituents wherein, eugenol (82.68%), eucalyptol (64.80%) and D-limonene (83.35%) were the major component of cinnamon, eucalyptus and orange oils, respectively. Contact toxicity results indicated that at 120 hours after treatment (HAT), eucalyptus oil caused significantly maximum mortality (100%) of S. oryzae when treated with 0.75 μl/cm2 concentration in comparison to fumigant toxicity (83%) at 2 μl/500 cm3 concentration. The present study demonstrated that among the treated oils, eucalyptus oil has higher contact, fumigant and repellent toxicity and hence it can be harnessed for integrated management of S. oryzae under storage condition.
TL;DR: Test results indicated significant improvement in BTE (brake thermal efficiency) with all modes with moderate energy shares of eucalyptus oil and peak pressure and energy-release rate indicated as superior to neat MO at all modes mainly at 100% load.
Abstract: This work aims at combusting a high viscous high cetane biofuel completely and efficiently under dual combustion mode using another low viscous low cetane biofuel. Maduca longifolia oil (MO) was selected as the base fuel. Combustion was achieved by using EFI (electronic fuel injection) and carburetion of eucalyptus oil at the intake manifold. Eucalyptus oil was also blended externally with MO at different mass ratios and tested. A comparison of engine results was made at 100% and 40% loads (power outputs) for all the attempts. Test results indicated significant improvement in BTE (brake thermal efficiency) with all modes with moderate energy shares of eucalyptus oil. The BTE increased from 25.2% with neat MO operation to a maximum of 29%, 32.3%, and 33.4% respectively with eucalyptus oil addition, carburetion, and EFI modes whereas it was observed as 30.8% with ND (neat diesel). Smoke was reduced with eucalyptus oil addition, carburetion, and EFI at the maximum efficiency points at 100% load. Peak pressure and energy-release rate indicated as superior to neat MO at all modes mainly at 100% load. Thirty percent, 40.2%, and 30.4% respectively with eucalyptus oil addition, carburetion, and EFI were recommended to be the optimal mass shares for 100% load. EFI of eucalyptus oil could be preferred for the highest BTE, lowest smoke, and NO emissions and maximum replacement of MO for the optimal operation of the engine among the methods tested.
