| host-parasite interactions between whiteflies and their parasitoids. | there is relatively little information available concerning the physiological and biochemical interactions between whiteflies and their parasitoids. in this report, we describe interactions between aphelinid parasitoids and their aleyrodid hosts that we have observed in four host-parasite systems: bemisia tabaci/encarsia formosa, trialeurodes vaporariorum/e. formosa, b. tabaci/eretmocerus mundus, and t. lauri/encarsia scapeata. in the absence of reported polydnavirus and teratocytes, these paras ... | 2005 | 16304614 |
| phytosociological and ecological structure of mediterranean enclaves along the stream valleys in inner parts of black sea region. | in this study phytosociological structure of mediterranean enclaves which occured along the stream valleys in inner parts of black sea region was investigated. pinus brutia var. brutia and quercus coccifera are the most widespread communities in the study area. pinus pinea, arbutus andrachne, arbutus unedo, fontanesia philliraeoides subsp. philliraeoides and olea europaea l. var sylvestris have a restricted distribution in inner parts of black sea region as compared to p. brutia and q. coccifera ... | 2010 | 20648812 |
| arbutus andrachne l. reverses sleep deprivation-induced memory impairments in rats. | sleep deprivation (sd) is associated with cognitive deficits. it was found to affect the hippocampus region of the brain by impairing memory formation. this impairment is suggested to be caused by elevation in oxidative stress in the body, including the brain during sd. it was hypothesized that the methanolic extract of the fruits of arbutus andrachne l. (ericaceae) will prevent chronic sd-induced impairment of hippocampal memory via its antioxidative properties. the methanolic extract of the fr ... | 2017 | 28101814 |
| effects of methanol extracts from roots, leaves, and fruits of the lebanese strawberry tree (arbutus andrachne) on cardiac function together with their antioxidant activity. | several plant-derived natural products have been used in clinical phase for applications in neurological, cardiovascular, and inflammatory diseases. arbutus andrachne l. (ericacea) is an evergreen shrub native to the mediterranean region. traditionally, the fruits and leaves of arbutus tree are well known and used as antiseptics, diuretics, blood tonic, and laxatives. | 2016 | 26511200 |
| studying the anti-tyrosinase effect of arbutus andrachne l. extracts. | arbutus andrachne l. is widely distributed in jordan. tyrosinase is the key enzyme in the biosynthesis of melanin. this preliminary study was carried out to assess the possible anti-tyrosinase activity of a. andrachne extracts. arbutin, hydroquinone and kojic acid were selected as inhibitor standards. five different extracts (chloroform, butanol, ethanol, methanol and water) were prepared from a. andrachne stems and their activities were compared with the selected tyrosinase inhibitors. ic(50) w ... | 2008 | 18713073 |
| effect of cold stratification treatments on germination of drought tolerant shrubs seeds. | this study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. the species used in this study were arbutus andrachne l., cistus creticus l., colutea armena bois. huet., cotinus coggygria scop., cotoneaster numullaria fisch. and mey, elaeagnus angustifolia l., jasminum fruticans l., paliurus spina-christii mill., punica granatum ... | 2007 | 17929764 |
| antimicrobial and anti-inflammatory potential therapy for opportunistic microorganisms. | methanolic extracts of six plants (arbutus andrachne, chrysanthemum coronarium, inula viscosa, origanum syriacum, punica granatum, and rosmarinus officinalis) used in traditional medicine for the treatment of bacterial and fungal infections were evaluated. the present study was conducted to evaluate the antimicrobial and anti-inflammatory activity of some medicinal plants in lowering the risk of opportunistic infections of the oral cavity caused by staphylococcus aureus, pseudomonas aeruginosa, ... | 2016 | 27249525 |
| diapause and its regulation in the whitefly trialeurodes lauri. | this study focuses on the regulation of synchronization between the life cycle of the oligophagous whitefly, trialeurodes lauri (signoret), and its evergreen host tree arbutus andrachne in mediterranean chaparral. whitefly infestations vary considerably among trees. the adults of the univoltine (one generation per year) whitefly emerge en masse during april and may and oviposit on the new spring foliage. following approximately one month of development to the early fourth instar, the nymphs ente ... | 2010 | 21092381 |
