effects of rosmarinus officinalis and salvia officinalis essential oils on tetranychus urticae koch acari tetranychidae
Industrial Crops and Products, 2013Co-Authors: Rafael Laborda, Israel Manzano, M Gamon, Isabel Gavidia, Pedro Perezbermudez, Rafael BoludaAbstract:Abstract Laboratory trials were carried out to characterize Rosmarinus officinal and Salvia officinalis essential oils and to evaluate their pesticidal activities against Tetranychus urticae. Slide-dip and leaf-disk bioassays were employed to study the mortality caused by these plant oils on two-spotted spiders. Different dilutions of both essential oils (0.10–0.25%, v/v) caused acute contact toxicity, although the sage extract showed greater acaricidal activity than Rosemary oil. Mortality rates of 95–100% were observed at all the sage oil dosages and when Rosemary emulsions contained at least 0.20% of essential oil. In the residual contact experiments (leaf-disk assays), 0.15–0.25% of sage oil or 0.25% of Rosemary extracts significantly reduced mite survival. Leaf-disk bioassays were also used to evaluate the effects of oils on T. urticae fecundity. The total number of eggs oviposited decreased as the oil dosage increased and rate reductions were significant when 0.15–0.25% of sage or 0.25% of Rosemary extracts were sprayed onto leaf-disks. The effect of oil treatments on the number of emerged larvae was similar to that on egg oviposition. Mite eggs were more susceptible to sage residuals, and significant reductions in larva emergence rates were observed with both sage dosages after 8 days of treatment. Rosemary and sage extracts showed no insecticidal activity against Ceratitis capitata, although sage oil greatly attracted adult flies (see supplementary file).

Effect of combined treatment with supercritical CO2 and Rosemary on microbiological and physicochemical properties of ground pork stored at 4°C.
Meat Science, 2017Co-Authors: Shirong Huang, Bin Liu, Jiehui DaiAbstract:Abstract The effect of combined treatment with supercritical CO2 (2000 psi, 35 °C for 2 h) and Rosemary powder (2.5% and 5.0% (w/w)) on microbiological and physicochemical properties of ground pork stored at 4 °C was investigated. The changes in total viable count, pH, total volatile base nitrogen (TVB-N), lipid oxidation and instrumental color (CIE L⁎, a⁎, b⁎) were analyzed during a week period of refrigerated storage. It was found that microbial populations were reduced by supercritical CO2 treatment, with the more pronounced effect being achieved by combined treatment with supercritical CO2 and 5.0 g Rosemary powder/100 g meat. Supercritical CO2 treatment for 2 h could accelerate lipid oxidation of ground pork during refrigerated storage, whereas combination with Rosemary can significantly slow down the increase of oxidation rate. Combined treatment of supercritical CO2 and Rosemary significantly increased L⁎ and b⁎ values of the ground pork, while the a⁎, pH and TVB-N value were not affected as compared to the treatment with supercritical CO2 alone. The results of this study indicate that combined treatment of supercritical CO2 and Rosemary may be useful in the meat industry to enhance the storage stability of ground pork treated with long time exposure of supercritical CO2 during refrigerated storage.
