Protection Time

The insecticidal and repellent activities of essential oil from leaves ofEucalyptus grandisagainstCulex pipiens quinquefasciatuswere investigated. The essential oil was obtained by hydro-distillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The principal constituents in the essential oil werep-cymene (26.794%),α-pinene (15.864%), eucalyptol (6.281%),α-terpineol (4.100%), limonene (3.614%) and borneol (2.519%). The results indicated that the essential oil ofEucalyptus grandisleaves hold insecticidal and repellent activities againstCulex pipiens quinquefasciatus. The complete protection time for people againstCulex pipiens quinquefasciatuswas correlative with its concentration. It could protect people for 7h when its concentration was 50%. Fumigating insecticidal activity was evaluated by airtight fumigation in conical flask. The LC50values of the essential oil for adults ofCulex pipiens quinquefasciatuswere 4.5%(0.5h), 3.6%(1h), 2.6%(2h), 2.1%(4h), 0.56%(8h) and 0.56%(24h). The LT50value of the essential oil was 19.1 min when its concentration was 6.4%.

The Impact

Microorganism control in food has been a challenge due to the legislation restrictions of each country and the increase in the demand for food without chemical preservatives. Plant essential oils have antimicrobial action and are promising for the use in the food industry. Our study aimed to evaluate the chemical composition and the antimicrobial effect of Schinus terebinthifolius Raddi fruit essential oil on minas frescal cheese. The essential oil was extracted by hydrodistillation, and the chemical compounds were identified by gas chromatography coupled to mass spectrometry. The major identified compounds were hydrocarbon monoterpenes (57.0%), mainly: α-pinene (22.2%), limonene (17.0%), carvone (10.2%) and β-phellandrene (7.9%). The cheese was produced, the main microorganisms were isolated, and the minimum inhibitory concentration was determined through broth microdilution test.  The cheese samples were soaked. The pink pepper fruit essential oil was added to the cheese samples at the concentration of 20000 μL/mL superficially or to the micelle. S. terebinthifolius fruit essential oil was efficient to control minas frescal cheese microorganisms mainly when applied by superficial addition. The essential oil is a potential source of studies to develop applications for the control of microorganisms in cheese such as minas frescal. Further studies may exploit the impact of the essential oil in minas frescal cheese acceptability.

Background: In Morocco, the species Culex pipiens (Diptera: Culicidae) has developed resistance to the synthetic insecticide. Therefore, there is an urgent need to find alternatives to the insecticides, as natural herbal biocides. Objective: The essential oil of Mentha pulegium grown the North center of in Morocco has been analyzed and their larvicidal activity on Culex pipiens was determined. Methods: The analysis and the identification of the various constituents of essential oilobtained by hydro-distillation of the aerial part were carried out by Gas Chromatography coupled with Mass Spectrometry (GC/MS). Biological tests were realized according to a methodology inspired from standard World Health Organization protocol. The larvicidal activity of medicinal plant extracts were tested against early fourth-instar larvae of Culex pipiens. The repellent efficacy was determined against of mosquito species (Culex pipiens) at six concentration’s (5, 10, 20, 40, 80 and 160 ppm) under the laboratory condition. The mortality was observed 24h after treatment; data were subjected to probit analysis to determine the Lethal Concentrations (LC50 and LC90) to kill 50 and 90 percent of the treated larvae of tested species. Results: The major constituents of Mentha pulegium essential oil were identified as pulegone (53.23%), α-pinene (12.1%), piperitone (9.62%), menthone (9.26) and piperitenone (6.6%). The LC50 and LC90 were estimated at 25.45 ppm and 98.66 ppm respectively. Conclusion: This investigation indicates that the Mentha pulegium essential oil could serve as a potential larvicidal and could be used as an ideal ecofriendly approach for the control of the Culex pipiens.

Anacyclus pyrethrum is a herbaceous plant that belongs to the Asteraceae family. The focus of the present study is to extract the essential oil from this plant, to determine its chemical composition and to evaluate its insecticidal activity against the larvae of the mosquito Culex pipiens. The essential oil from A. pyrethrum collected from the region of Bensliman in Morocco was extracted by hydrodistillation and analyzed by gas chromatography coupled to mass spectrometry were studied. Essential oil yield obtained by hydrodistillation was 0.09%. The major aroma constituents were Spathulenol (20.47%), Germacrene D (16.48%), Caryophyllene oxide (13.20%), 4(14)-Salviale-1-one (8.27%) and Caryophyllene 4(14),8(15)-dien-5α-ol (7.30%). The larvicidal test carried out according to a methodology based on the standard protocol of the World Health Organization was studied on 4th instar larvae of C. pipiens and showed that A. pyrethrum essential oil possesses remarkable insecticidal properties.  After 24 hours of exposition, larvicidal assays revealed a 100% mortality of C. pipiens larvae. The dose of 40 μL/mL was toxic enough to cause 100% larval mortality of C. pipiens. The lethal concentrations LC50 and LC90 calculated for the essential oil studied were of the order of 14.79 μL/mL and 19.95 μL/mL, respectively. To control mosquitoes, this essential oil extracted from A. pyrethrum might be used as a natural insecticide and therefore could be an alternative to synthetic insecticides already present on the market.
