The mosquito vector Aedes aegypti L., plays an important role in transmission of diseases including dengue, chikungunya and zika fever. In this study, citronella leaf oil extracted by hydro-distillation technique has been evaluated for its efficacy against vector. Citronella (100, 125, 150, 175 200 ppm) when tested, 150 ppm was found to be the effective larvicidal concentration 4th instar larva...

The present investigation was undertaken to study the cytotoxic and genotoxic potential of the essential oils (palmarosa, citronella, lemongrass and vetiver) and monoterpenoids (citral and geraniol) in human lymphocytes. Trypan blue dye exclusion and MTT test was used to evaluate cytotoxicity. The genotoxicity studies were carried out by comet and DNA diffusion assays. Apoptosis was confirmed b...

The main focus of this research is to modify the straight pipe Citronella essential oil distillation condenser using a helical coil shorten time. This study aims obtain an effective shell-side fluid volumetric rate shell side varies from 0.72 3.66 LPM at constant pitch ratio 2.10. Recording data in form temperature, water, and tube steam after steady state reached. experimental results show tha...

Three commercial repellents marketed in Tanzania: Zero Bite (a blend of microcrystalline waxes, mineral oils, natural flavours, Olibanum oil, Eucalyptus oil, Geranium oil, Citronella oil and Isopropyl myristrate); X-pel (a petroleum jelly formulation containing diethyl toluamide (DEET) and dimethyl phthalate); No Bite (a spray formulation with diethyl toluamide, 2 methyl 2,4 pentondiol and ptha...

a study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (ocimum basilicum l.). the research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. the experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

The African red mite (Eutetranychus africanus [Tucker]) is an important pest species of some economic plants. objective the present study was to evaluate effectiveness nanoemulsions consisting citronella grass, lemongrass, clove, and cinnamon essential oils their main chemical compounds against mite; toxicity, egg-laying inhibition, repellent effect on were determined. Essential oil (nEOs) prep...

This study aims to determine whether the combination formulation of essential oils between cinnamon and citronella can be used as an aromatherapy reed diffuser preparation that has acted anti-stress aromatherapy. The method in this research is experimental laboratory with a post-test only control group design using mice test animals. population was Cinnamon (Cinnamomum verum) (Cymbopogon nardus...
