| This study aimed to identify the constituents of the essential oil from Hyptis suaveolens (L.) leaves using a Gas Chromatograph -Mass Spectrometer and assess its inhibitory effect on some potentially pathogenic Aspergilli (A. flavus, A. parasiticus, A. ochraceus, A. fumigatus and A. niger). Eucaliptol (47.64 %) was the most abundant component in the oil, followed for gama-ellemene (8.15 %), beta-pynene (6.55 %), (+)3-carene (5.16 %), trans-beta-cariophyllene (4.69 %) and germacrene (4.86 %). The essential oil revealed an interesting anti-Aspergillus property characterized by a Minimum Inhibitory Concentration and Minimum Fungicidal Concentration of 40 and 80 µL/mL, respectively. The oil at 80 and 40 µL/mL strongly inhibited the mycelial growth of A.... |

| Trichophyton mentagrophytes is a fungus causative agent of dermatophytosis, affecting humans worldwide. This has driven the search for products for the treatment of these infections. Accordingly, the aim of this study was to investigate the antifungal activity of the Cymbopogon winterianus essential oil against T. mentagrophytes. The antifungal tests consisted of antifungal screening, determination of MIC and MFC, analysis of the essential oil's effects on mycelial growth, germination of fungal spores, fungal viability, morphogenesis, cell wall (test with sorbitol) and cell membrane (cell leakage test) of T. mentagrophytes. Upon screening, the oil inhibited all strains, with zones of growth inhibition of 24-28 mm in diameter. The MIC was 312 μg/mL and CFM... |

| Estudaram-se a presença e a ação de himenópteros parasitóides em agroecossistema de batata-doce (Ipomoea batatas L.) no município de Pedra de Fogo - PB, sobre o complexo Megastes spp, com o objetivo de identificar as espécies de parasitóides existentes, bem como descrever os principais eventos na ação de parasitismo sobre Megastes grandalis Guenee e Megastes pusialis Snellen. No levantamento direto, em 14% das plantas, existiam fêmeas de microhimenópteros ectoparasitóides da família braconidae atacando lagartas de Megastes spp. No levantamento indireto, constatou-se um ataque de parasitóide em 22% das lagartas, emergindo adultos de sete espécies das famílias braconidae, Chalcididae e Ichneumonidae, com predominância de braconídeos ectoparasitóides.... |
