“…Each solution was dispensed on the paper surface that was afterwards placed in glass Petri dishes (9 cm diameter, 1 cm high). After 10 min, once the solvent had been evaporated, 10 unsexed adults were deposited into each glass Petri dish and stored in darkness at the same temperature and RH conditions (Caballero-Gallardo et al, 2012). Three replicates were made for each treatment, EO and analytical standard eucalyptol (1,8-cineole, purity ≥ 99.0% Fluka, St. Louis, Minnesota, USA) solutions, at the previously mentioned concentrations.…”

The confused flour beetle, Tribolium confusum Jaquelin Du Val, 1868, is a common pest insect known for attacking and infesting stored flour and grain. Biodegradable and ecologically natural products such as essential oils are emerging candidates for replacement of usually applied chemical pesticides. This work reported the chemical composition and effects caused by young and mature leaves essential oils (EOs) from Eucalyptus globulus Labill. against T. confusum. For both oils, no significant differences between yields were observed, being 1,8-cineole the main common constituent. Mature leaves extracts were rich in oxygenated mono-and sesquiterpenes, whereas young leaves showed greater content of nonoxygenated compounds. Bioassay was performed using EOs and 1,8-cineole solutions at different concentrations and time intervals. Adult mortality increased according to concentration and exposure time; young leaves extracts exhibited the greater effectiveness, highest mortalities (31.67%) at the minor time (2 h). At the lowest concentrations, 1,8-cineole solutions and mature leaves EOs did not achieve 100% mortality even when the bioassay was concluded (12 h), while at major doses no insects were alive. These results suggested that young and mature EOs from E. globulus constitute an alternative natural product to the control of T. confusum, since young leaves extracts, rich in monoterpene and sesquiterpene hydrocarbons, may be potential eligible candidates considering their noticeable insecticidal effects at low applied concentrations and short times of exposure.

“…As a consequence, aromatic plants are studied as potential sources of repellents and insecticides (Nerio et al, 2010;Shaaya and Kostyukovysky, 2006;Conti et al, 2010;Caballero-Gallardo et al, 2012;Olivero-Verbel et al, 2013).…”

Rhyzopertha dominica, Sitophilus zeamais, and Tribolium confusum are three of the major food-stuff pests who cause important economic losses of shelved products with special reference to pasta. Due to its long shelf life, pasta is highly exposed to insects that can penetrate into the packaging with consequences economically severe. Eco-friendly strategies to prevent such insect attacks to the final packaged product are therefore highly foreseen by pasta companies. Due to their repellent properties, essential oils, extracted from aromatic plants, could represent a valid, eco-friendly alternative to chemical repellents. In this study, we evaluated the repellent activity of Pistacia lentiscus essential oil (PEO) and its main chemical components by two different bioassay with and without the presence of pasta. Results showed that the whole PEO exerts a broad-range aspecific repellency among the target pests with RD50 values ranging from 0.010 to 0.037 μL cm−2. On the contrary, the repellence of PEO components resulted to vary depending on the compound and on the pest species. Among the PEO chemical components, relative median potency analyses indicated that β-caryophyllene was able to exert the highest repellency rates against S. zeamais (RD50 0.046 μM cm−2). The comparison between the two bioassays, with and without pasta, indicated that the two methodologies gave consistent results. Overall, our research firstly showed that, because of their effectiveness as repellents, PEO and its major constituents could represent valid and safe tools against pasta pest

“…9 Lippia origanoides essential oil (LOEO) exhibits an antigenotoxic effect in bacterial cells, demonstrating that this plant can be an important source of compounds with applications in cancer chemoprevention. 10 LOEO has also shown antioxidant activity and low toxicity, 11,12 as well as, antimicrobial activity against several pathogens. [13][14][15] However, the biological activities of extracts obtained from this species remain rarely studied.…”

An ethanol extract and different partition fractions obtained from Lippia origanoides H.B.K. were assayed for light-mediated activity against strains of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Identical assays were conducted with and without exposure to UV-A (400-315 nm) light to test for light enhanced activity. The ethanol extract and dichloromethane fraction showed light-mediated activity against the S. aureus strain, but not against the E. coli strain. The dichloromethane fraction was more active than the ethanol extract. Naringenin did not display light-mediated activity against the tested bacteria, indicating that the light-mediated antimicrobial activity of the dichloromethane fraction is not due to its major component. The results represent the first report of light-mediated antimicrobial activity of Lippia origanoides and show that its phytochemicals could be used as light-mediated antimicrobial agents.
