background: essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. so five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach supella longipalpa . methods : evaluation was done against the 3 rd and 4 th instar nymphs using three bioassay methods...

In this contribution, pressurized liquid extraction (PLE) has been employed to isolate bioactive compounds from three native Romanian plants, oregano (Origanum vulgare), tarragon (Artemisia dracunculus) and wild thyme (Thymus serpyllum). Different PLE conditions have been tested including extraction with water, ethanol and their mixtures in a wide range of extraction temperatures (50-200°C), an...

In the present study, it was aimed to investigate the effect of oregano (Origanum onites) essential oil (EO) on biofilm formation and established biofilm. Staphylococcus aureus (n=6), Staphylococcus lugdunensis (n=1), Staphylococcus haemolyticus (n=1), Staphylococcus sciuri (n=1) and Escherichia coli (n=1) were used as the test organisms. The crystal violet assay was used for assessing the grow...

Aim of the present study was the comparative evaluation of the effect of ground oregano, anise and olive leaves as feed additives on performance and some egg quality characteristics of laying Japanese quails. A total of 189 Coturnix japonica quails (126 females and 63 males), 149 days old, were randomly allocated into seven equal groups with three subgroups of 9 birds each (6 females and 3 male...

Control of the skin parasitic ciliate Ichthyophthirius multifiliis is currently based on laborious chemical and mechanical approaches, thus advocating for alternative control measures. Here, we show that early development trophonts (feeding stage residing in epidermis) Rainbow Trout Oncorhynchus mykiss epidermis was inhibited at 5 d postinfection after administration feed additives, including g...

In the current study, we screened 7 clonal lines from single seed phenotypes of Lamiaceae family for the inhibition of alpha-amylase, alpha-glucosidase and angiotensin converting enzyme (ACE) inhibitory activity. Water extracts of oregano had the highest alpha-glucosidase inhibition activity (93.7%), followed by chocolate mint (85.9%) and lemon balm (83.9%). Sage (78.4 %), and three different c...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...

Oregano, Origanum vulgare L., is a perennial herbaceous plant belonging to the Lamiaceae family. Oregano shows variations in biomass yield and essential oil (EO) content due influence of abiotic biotic factors. The aim this study was assess effect different foliar applications based on calcium (Ca) nitrogen (N) morphological productive parameters oregano. Tests were carried out Sicily (Italy) 2...

This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...

Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and...
