Ocimum basilicum L. (Lamiaceae) is one of the most popular herbs in the world, given its aromatic, medicinal and insecticidal properties. Its leaves are rich in essential oils, as well as the plant part with the highest economic value in this species. The aims of the current study are to identify the causative agent of injuries observed in sweet basil plants grown in Seropédica County, RJ (Brazil), as well as to feature both their feeding behavior and injuries caused by them. The herein investigated injuries were caused in sweet basil stems and leaves by caterpillars, which were collected with the leaves and grown in laboratory until they reached the adult stage. Two lepidopteran species belonging to family Crambidae were identified, namely: Hyalorista opalizalis (Guenée, 1854) and Pyrausta phoenicealis (Hübner, 1818); approximately 73% of adult individuals obtained in laboratory belonged to the first species. Caterpillars belonging to both species have caused similar injuries to O. basilicum plants. Injuries were featured by the sectioning of stems whose leaves were bundled with silk threads and formed a shelter, where caterpillars ate the leaf limb in. The current study also recorded O. basilicum plants used as hosts by P. phoenicealis insects, for the first time.

Antifungal Activity of Essential Oils from Two Varieties of Sweet Basil (Ocimum basilicumL.)The aim of this work was an evaluation of the antifungal activity of essential oils from two cultivars of sweet basil (Ocimum basilicumL.): ‘Wala’ and ‘Fine Verde’. The essential oils from dried, ground herbs were extracted with the hydro-distillation method using Deryng apparatus. The composition of the oils was analyzed by gas chromatography. The antifungal activity of the oils was tested against the following strains:Alternariasp.,Aspergillus flavus, Botrytis cinerea, Cladosporium herbarum, Eurotium amstelodamiandEurotium chevalieri. The disc diffusion agar method was applied. Each oil was used in two doses, 10 and 5 μl/disc. A disc (6 mm dia.), soaked with oil, was placed on agar plates, which had been previously inoculated with spores of the different strains. The diameters of fungal growth inhibition zones were measured after 72h of incubation at 25°C and expressed in millimeters. The obtained results showed that the diameter of the mycelium growth inhibition zone significantly depended on the source of oil, the dose of oil, and the species of fungi. The essential oil from the ‘Wala’ variety was more effective against the tested fungi than the oil from ‘Fine Verde’ and the inhibition zones were greater when the dose of the oils was higher.E. chevalieriwas the most sensitive to both of the oils andA. flavuswas the most resistant. The differences in the antifungal activity of the tested oils were probably the result of their different chemical compositions. In comparison with the ‘Fine Verde’ oil, the oil from ‘Wala’ had more than twice the amount of linalool, more 1,8-cineole, and contained geraniol and methyl chavicol. In the conditions of the experiment both oils showed greater antifungal activity than cycloheximide (actidion) and methyl thiophanate (Topsin M 500 SC) used as controls.

Basil (Ocimum basilicum L., fam. Lamiaceae) is an important medicinal and aromatic plant with very wide range of uses. This paper presents qualitative and quantitative analyses of essential oils obtained from five types of Italian basil cultivars: Napolitan, Red basil, Fino Verde, Limonez, and Genoveze culltivated in Albania and collected during the summer 2012. The hydrodistilled BEO (Basil essential oil) content ranged from 0.11% to 3.40%. Within the total of 65 identified compounds with GC/FID/MS, nine were considered as predominant (1,8-cineole, linalool, cis-thujone, methyl chavicol, eugenol, trans-(E)-caryophyllene, trans-(α)-bergamotene, germacrene D, and epi-α-cadinol) representing 49.20 to 85.43% of the components in the analysed essential oils. In all cultivars, linalool was detected as the most abundant component (36.20-46.59%). BEO’s from all five cultivars differ in their chemical composition but generally conform to EO’s from Sweet Basil grown in the Medditeranean region. The Napolitan cultivar showed the largest similarity to Sweet Basil, not only for the morphology, also due to the essential oil composition that comprises Basil’s most dominant chemical components (linalool, methyl chavicol and eucalyptol) in particular percents.

<em>Calliphora</em> <em>vicina</em> (Diptera: Calliphoridae) it is a facultative ectoparasite responsible for traumatic myiasis in humans and warmblooded vertebrates in the world. In this work one case of traumatic myasis caused by<em> C. vicina</em> (Diptera Calliphoirdae) is reported for the first time in a vulnerable crested porcupine (<em>Hystrix</em> <em>cristata</em> Linnaeus, 1758). A total of 30 larvae located in the posterior-dorsal area of the animal were removed from inside the lesion and either preserved in ethanol or reared to the adult stage. This report shows the great ability of <em>C. vicina</em> to use many organic matter for the food source’s offspring, including many live vertebrates.
