Composition and insecticidal activity of essential oil from Ruta graveolens, Mentha pulegium and Ocimum basilicum against Ectomyelois ceratoniae Zeller and Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)

Objetivou-se avaliar a organização social das feiras livres frente a disponibilidade de mudas e partes secas vegetais de plantas medicinais, aromáticas e condimentares (MAC), ofertadas aos consumidores em feiras livres do município de Chapecó-SC. Os dados foram coletados visualmente através de visitas às feiras livres, em dois diferentes momentos. Os resultados demonstram que as feiras livres do município estão disposta em 10 espaços distintos dentro da área urbana, totalizando 16 momentos de realização distribuídos entre os dias da semana. De maneira geral, os espaços ofertam diversos produtos aos consumidores, entre os quais estão as espécies MAC tano na forma de mudas quanto de partes secas, esta última representando, em média, 72% do total. A oferta da maioria das espécies não foi influenciada pela data de avaliação, sendo as mais recorrentes a Ruta graveolens, Matricaria chamomilla, Rosmarinus officinalis, Aloysia citriodora, Mentha pulegium, Plectranthus barbatus, Citrus sinensis, Mikania glomerata, Helichysum italicum, Mentha sp., Artemisia absinthium, Salvia officinalis, Ocimum basilicum, Origanum majorana, Achyrocline satureioides, Malva sylvestris, sendo encontradas tanto em mudas como partes secas.

Antibacterial And Antifungal

The chemical composition and antibacterial, insecticidal, and antioxidant properties of the essential oil from Mentha pulegium L. (M. pulegium) growing in Morocco were investigated in this work. To achieve this goal, the oils were obtained by using hydrodistillation before being characterized by GC-MS. The antibacterial and antifungal activities were conducted against pathogenic strains using the disc diffusion and MICS bioassays. The insecticidal activity was carried out versus C. maculatus using contact and inhalation tests. The antioxidant activity was performed by using DPPH and total antioxidant capacity bioassays. The chemical analysis of the oil showed that 20 compounds were identified, which represented 98.91% of the total oil. In the oil, the main components detected were R-(+)-pulegone (76.35%), carvone (5.84%), dihydrocarvone (5.09%), and octanol-3 (2.25%). The essential oil has moderate-to-strong broad-spectrum antibacterial and antifungal properties; the results showed that B. subtilis was the most sensitive strain to M. pulegium oil, with the largest inhibition diameter (25 ± 0.33). For the antifungal activity, the results obtained indicated that Aspergillus niger was the most sensitive fungal strain to M. pulegium oil with an inhibition percentage up to 100%. Regarding the insecticidal activity, the inhalation test showed a high efficacy (100% mortality), and a lethal concentration of LC50 = 1.41 + 0.48 μL/L air was obtained after 24 hours of exposure. Moreover, the contact test showed that a total reduction in fertility and emergence was obtained with a dose of 20 μL/mL of acetone. Regarding the antioxidant activity, the sample concentration necessary to inhibit 50% of HE radicals (IC50) was 7.659 mg/mL (DPPH) and 583.066 57.05 mg EAA/g EO (TAC).
