Conservation of stored food using plant's extracts. Effect of oregano (Origanum vulgaris) essential oils on the reproduction and development of flour moth (Ephestia kuehniella)

The aim of our work is to assess physicochemical and antibacterial potential of two local honeys compared with two imported honeys. A carbohydrate profile was carried out by HPLC. All honeys are acid and the free acidity of Zriba (36 ± 13 méq.kg -1 ), Sidi Achour (36.66 ± 0.57 méq.kg-1) were in standards well above those of imported honey: San Francisco (7 méq.kg -1 ), Elshifa (20 méq.kg-1). Refractive index complied with the standards. Sidi Achour honey was denser (1.4206) than the others. Ash content of local honey (0.76 ± 0.07) and imported honey San Francisco (0.72 ± 0.57) were higher than those of Zriba honey (0.41 ± 0.08) and Elshifa (0.25 ± 0.038). All honeys had a sucrose content within the standard. Local honey contained Trehalose and melezitose, and richer in fructose and raffinose, F & G and maltose levels were consistent with standards. Sidi Achour contained the highest turanose content (2.15 ± 0.49%) relative to the studied honey samples. Antibacterial activity showed that all honeys have antibacterial potential when they are pure. Sidi Achour was active against E.coli (24 ± 6.08 mm), S.enteritidis (26.33 ± 1.15 mm), S.aureus (19.66 ± 0.57 mm), B.cereus (13.33 ± 8.73 mm) and E.faecalis (15 ± 1 mm). Zriba honey showed the same antibacterial honey except for B.cereus (7.66 ± 2.88 mm). The imported honeys were active on the growth of only three bacteria: E.coli, S.enteritidis and S.aureus.

For the purpose of evaluating the local heritage of eastern Numidia, an ethnobotanical survey was conducted on a population located in the province (department) of El-Tarf (North-East of Algeria) on a frequency of use of two plants known in traditional health; Eucalyptus globulus (Myrtaceae) and Rosmarinus officinalis (Lamiaceae). After processing data, our results show a female dominance when using these plants on a fairly advanced age group (40 to 60 years old). These plants are used by the people at their fresh state and deem the leaf as the most used part for therapeutic and cosmetic purposes. Furthermore, steam baths and infusion remain the most widespread preparation methods. Most consumers use these plants to treat influenza, respiratory illnesses as well as diseases of the digestive tract. GC-MS of essential oils extracted from the plants studied disclose a dominance of the alcohols portrayed by the monoterpenes (42.73%), sesquiterpenes (32.6%) and oxides (10.48%) in E. globulus. Data also indicate a high content of oxides (38.11%) monoterpene alcohols (20.43%) and monoterpenes (19.70%) in R.officinalis. Toxicological contact tests were achieved on a store-products pest Ephestia kuehniella. The test results were assessed with E.globulus (LC50=0.013; LC95=0.081 µl/cm 2 ) and R.officinalis (LC50=0.011; LC95=0.059 µl/cm 2 ). The lethal time changes according to the dose used and the tested plant. In E.globulus, we observe (concentration: 0.005 µl/cm 2 ; LT50=56.2 h), (Concentration: 0.01 µl/cm 2 ; LT50=49.53h) and (Concentration: 0.04µl/cm 2 ; LT50=20.93h). Whereas in R.officinalis, we recorded (Concentration: 0.005 µl/cm 2 ; LT50=55.7h), (Concentration: 0.01µl/cm 2; LT50=54.99 h) and (Concentration: 0.04µl/cm 2 ; LT50=29.13 h). The bioinsecticide has also been administered by fumigation and underpins toxicity by the reduction of adults longevity in E.kuehniella with R.officinalis (LC50=4.03 µl/l air; LC95=14.73 µl/l air) and E.globulus (LC50=7.76 µl/lair; LC95=21.23 µl/l air). In addition, the tested plants show an outstanding repellent effect as long as E.globulus and R.officinalis essential oils respectively demonstrate a slightly repellent power at 42.22% (RD50=0.09 µl/cm 2 ; RD95=0.24 µl/cm 2 ) and repellent at 60.00% (RD50=0.06 µl/cm 2 ; RD95= 0.35 µl/cm 2 ) towards E.kuehniella adults. The plant resources represent a genuine reserve of bioactive molecules, which can create solutions to sustainable development issues. These plants might be the source of new molecules of combat against some pests in order to protect human health and safeguard the environment.

“…It was found to affect the pupal development. It also disrupted the reproduction of exuviated adults by extending the preoviposition period and reducing the period of egg-laying and fecundity because fecundated females could not live more than four days compared to the control group [209]. In a recent study, wormwood (A. herba-alba), O. vulgare and rue (Ruta montana) were evaluated for their repellent and fumigant toxic potential against larvae of the flour moth E. kuehniella.…”

Controlling Stored Products’ Pests with Plant Secondary Metabolites: A Review

To date, only a handful of pesticides have been authorized by the European Council for the protection of stored grains. Resistance issues and ecotoxicity concerns necessitate the development of ecofriendly tools in that direction. In this review, we refer to the recent findings on plant extracts and pure plant-derived substances with promising biological activity and the potential to be used as biopesticides for stored products. The main aim of biopesticides is to be effective against target pests, without harming humans and the environment. Many plant species, among those reported herein, are part of the human diet, and are thus not harmful to humans. Edible plant extracts produced with inorganic solvents represent safe candidates for use as repellants, fumigants or contact pesticides. Cinnamon, rosemary, parsley, garlic, oregano and basil are found in products destined for human consumption but also display significant biological activities. Interestingly, cinnamon is one of the most widely tested botanical matrixes, exhibiting the best lethal effects on almost all insect and mite taxa reported herein (Acaroidea, Coleoptera and Lepidoptera), followed by basil and garlic. Prunus persica,Azadirachta indica A. Juss and Carum sp. seem to be very promising too as miticides and/or insecticides, with A. indica already being represented commercially by a plant-derived acaricidal formulation.
