“…De plus, certaines plantes à fleurs pourraient aussi être implantées autour des champs pour favoriser la présence des auxiliaires. Des études récentes envisagent aussi l'utilisation de répulsifs (Deletre et al, 2016), et d'huiles essentielles (Zoubiri et Baaliouamer, 2014). Cependant, ces diverses méthodes restent à tester en conditions réelles au Gabon.…”

Résumé -Au Gabon, le rôle du maraîchage périurbain est essentiel à l'approvisionnement des villes en légumes frais, notamment à Libreville et Owendo. Lors d'une enquête menée dans trois périmètres maraîchers, un état des lieux a été réalisé sur les caractéristiques socio-économiques, la diversité des plantes cultivées et les pesticides utilisés. Les superficies exploitées vont de 0,08 ha à 0,4 ha par maraîcher selon les sites. Les exploitants interrogés sont à 51 % originaires du Gabon alors que 40 % sont originaires du Burkina Faso. Les espèces les plus cultivées tout au long de l'année sont l'amarante (Amaranthus hybridus L.), la laitue (Lactuca sativa L.), l'oseille de guinée (Hibiscus sabdariffa L.), la morelle noire (Solanum nigrum L.). Les ravageurs les plus importants sont les Aphididae et quelques coléoptères. Les produits phytopharmaceutiques les plus utilisés sont des insecticides neurotoxiques conventionnels. Une meilleure maîtrise du suivi des cultures, une vulgarisation en protection des cultures y compris sur l'emploi des pesticides ainsi que la possibilité de développer des systèmes de micro-crédits aux petits producteurs permettraient d'augmenter la production légumière périurbaine et sa qualité sanitaire, ainsi que d'accroître l'autonomie alimentaire locale.Mot clés : légumes / maraîchage / Afrique centrale / ravageur / pesticide Abstract -Peri-urban market gardening in Libreville and Owendo (Gabon): farmers' practices and sustainability. In Gabon, peri-urban gardening is an opportunity to provide vegetables to the main cities, such as Libreville and Owendo. Following a survey conducted in three market gardening areas, an inventory was conducted on the socio-economic characteristics, the diversity of crops, and pesticide uses. The cropped areas range from 0.08 ha to 0.4 ha per farmer, according to the site. National operators represent 51%, while people from Burkina Faso manage 40% of vegetable production. The most cultivated species throughout the year are amaranth (Amaranthus hybridus L.), lettuce (Lactuca sativa L.), Guinea sorrel (Hibiscus sabdariffa L.) and black nightshade (Solanum nigrum L.). The most important pests are Aphididae and some beetles. The most commonly used plant protection products are insecticides, mainly conventional neurotoxic. Best crop monitoring, pest control including pesticide application reduction, and the possibility to offer microcredit systems to small producers would help increasing peri-urban healthy vegetable production and increase local food autonomy.

“…EOs are neurotoxic, and there is evidence for interference with the neuromodulator octopamine (Enan 2005 ) or GABA-gated chloride channels (Priestley et al 2003 ). Zoubiri and Baaliouamer ( 2011 ) performed a detailed literature survey on 230 plants and listed the insecticidal activity of their essential oils along with the major active compounds.…”

Advances in Plant Biopesticides

Insect pests are considered the major hurdle in enhancing the production and productivity of any farming system. The use of conventional synthetic pesticides has led to the emergence of pesticide-resistant insects, environmental pollution, and negative effects on natural enemies, which have caused an ecological imbalance of the predator-prey ratio and human health hazards; therefore, eco-friendly alternative strategies are required. The plant kingdom, a rich repertoire of secondary metabolites, can be tapped as an alternative for insect pest management strategies. A number of plants have been documented to have insecticidal properties against various orders of insects in vitro by acting as antifeedants, repellents, sterilant and oviposition deterrents, etc. However, only a few plant compounds are applicable at the fi eld level or presently commercialised. Here, we have provided an overview of the broad-spectrum insecticidal activity of plant compounds from neem, Annona , Pongamia , and Jatropha . Additionally, the impact of medicinal plants, herbs, spices, and essential oils has been reviewed briefl y.

“…In addition, the phenomenon of resistance observed with many synthetic pesticides will develop more slowly with the use of plant extracts such as essential oils due to their complex mixtures of constituents . In recent years, particular interest has been attributed to essential oils due to their biological activities, such as antimicrobial and insecticidal activities . Essential oils are an alternative strategy to control pest and develop new biopesticides .…”

Essential oils are an alternative strategy to control pest and develop new biopesticides . The genera able to produce essential oils are distributed in a limited number of families, such as Myrtaceae, Lauraceae, Rutaceae, Lamiaceae, Asteraceae, Apiaceae, Cupressaceae, Poaceae, Zingiberaceae and Piperaceae …”

The essential oil from the leaves of Peperomia borbonensis from Réunion Island was obtained by hydrodistillation and characterized using GC-FID, GC/MS and NMR. The main components were myristicin (39.5%) and elemicin (26.6%). The essential oil (EO) of Peperomia borbonensis and its major compounds (myristicin and elemicin), pure or in a mixture, were evaluated for their insecticidal activity against Bactrocera cucurbitae (Diptera: Tephritidae) using a filter paper impregnated bioassay. The concentrations necessary to kill 50% (LC ) and 90% (LC ) of the flies in three hours were determined. The LC value was 0.23 ± 0.009 mg/cm and the LC value was 0.34 ± 0.015 mg/cm for the EO. The median lethal time (LT ) was determined to compare the toxicity of EO and the major constituents. The EO was the most potent insecticide (LT = 98 ± 2 min), followed by the mixture of myristicin and elemicin (1.4:1) (LT = 127 ± 2 min) indicating that the efficiency of the EO is potentiated by minor compounds and emphasizing one of the major assets of EOs against pure molecules.
