bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

Background:Tanacetum vulgare L. (Asteraceae) is a perennial herb that has been used to treat multiple ailments. Regional variability of the chemical composition of T. vulgare essential oils is well-known. Despite these regional chemotypes, most relevant studies did not analyze the complete chemical composition of the T. vulgare essential oil and its constituents in relation to their biological ...

Essential oils from aerial parts of Mentha piperita, M. spicata, Thymus vulgaris, Origanum vulgare, O. applii, Aloysia triphylla, Ocimum gratissimum, O. basilicum were obtained by steam destillation using a Clevenger-type system. These oils were screened for antibacterial and anti-Candida albicans activity using bioautographic method. Subsequently, minimal inhibitory concentration from oils was...

effects of mentha arvensis l. and mentha pulegium l. essential oils were investigated against oviposition deterrence, egg hatching and adults' mortality of callosobruchus maculatus f. essential oils were obtained by dry leaves that were subjected to hydrodistilation using a modified clevenger-type apparatus. all experiments were conducted at 25±1ºc, 65±5 % r.h. in the dark condition with 5...

Spotted wing drosophila (SWD, Drosophila suzukii (Matsumura), Diptera: Drosophilidae) is recognized as an economically important pest in North America and Europe as well as in Asia. Assessments were made for fumigant and contact toxicities of six Myrtaceae plant essential oils (EOs) and their components to find new alternative types of insecticides active against SWD. Among the EOs tested, Lept...

This study aimed to investigate the antibacterial and antibiofilm activities of essential oils Cuminum cyminum (CEO) Foeniculum vulgare (FEO) on clinically isolated Porphyromonas gingivalis (P. gingivalis) Prevotella intermedia intermedia). Subgingival plaque samples were collected from periodontal pockets (≥6 mm) patients with generalized severe periodontitis. Microbiological molecular tests p...

BACKGROUND Hydrodistillation (HD) and steam-distillation, or solvent extraction methods of essential oils have some disadvantages like thermal decomposition of extracts, its contamination with solvent or solvent residues and the pollution of residual vegetal material with solvent which can be also an environmental problem. Thus, new green techniques, such as supercritical fluid extraction and m...

One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per tr...

Abstract The aim of this study was to find alternatives (even partial) mineral nitrogen fertilization reduce its harmful accumulation in the edible parts fennel. Fennel ( Foeniculum vulgare ) is a perennial plant Apiaceae family grown for shoots, leaves, and seeds. present work conducted two successive seasons, 2018/2019 2019/2020, at farm Agricultural Botany Department, Faculty Agriculture, Ai...

This research was aimed at investigating the essential oil production, chemical composition and biological activity of a crop of pink flowered oregano (Origanum vulgare L. subsp. vulgare L.) under different spatial distribution of the plants (single and binate rows). This plant factor was shown to affect its growth, soil covering, fresh biomass, essential oil amount and composition. In particul...
