Electrophysiological and behavioral characterization of bioactive compounds of the Thymus vulgaris, Cymbopogon winterianus, Cuminum cyminum and Cinnamomum zeylanicum essential oils against Anopheles gambiae and prospects for their use as bednet treatments.

Emilie Deletre et al.

Parasites & vectors, 8, 316-316 (2015-06-13)

Laboratory and field studies showed that repellent, irritant and toxic actions of common public health insecticides reduce human-vector contact and thereby interrupt disease transmission. One of the more effective strategies to reduce disease risk involves the use of long-lasting treated

Bioactivity of the Cymbopogon citratus (Poaceae) essential oil and its terpenoid constituents on the predatory bug, Podisus nigrispinus (Heteroptera: Pentatomidae).

Bruno Pandelo Brügger et al.

Scientific reports, 9(1), 8358-8358 (2019-06-09)

Podisus nigrispinus Dallas (Heteroptera: Pentatomidae), released in biological control programs, is a predator of Lepidopteran and Coleopteran species. Lemongrass essential oil and its constituents can be toxic to this natural enemy. The major constituents of lemongrass essential oil are neral

Mosquito odorant receptor for DEET and methyl jasmonate.

Pingxi Xu et al.

Proceedings of the National Academy of Sciences of the United States of America, 111(46), 16592-16597 (2014-10-29)

Insect repellents are important prophylactic tools for travelers and populations living in endemic areas of malaria, dengue, encephalitis, and other vector-borne diseases. DEET (N,N-diethyl-3-methylbenzamide) is a 6-decade-old synthetic repellent, which is still considered the gold standard of mosquito repellents. Mosquitoes

Identification of olfactory receptor neurons in Uraba lugens (Lepidoptera: Nolidae) and its implications for host range.

Kye Chung Park et al.

Journal of insect physiology, 78, 33-46 (2015-05-06)

Phytophagous insects detect volatile compounds produced by host and non-host plants, using species-specific sets of olfactory receptor neurons (ORNs). To investigate the relationship between the range of host plants and the profile of ORNs, single sensillum recordings were carried out

Sporicidal Activities of Various Surfactant Components against Bacillus subtilis Spores.

Won-Il Cho et al.

Journal of food protection, 78(6), 1221-1225 (2015-06-04)

The sporicidal activities against Bacillus subtilis spores of surfactant components with hydrophilic and hydrophobic properties that can lead to the denaturation of various proteins comprising the spore structure were investigated. The reduction in spore numbers by each of the surfactant

Parallel dual secondary column-dual detection: a further way of enhancing the informative potential of two-dimensional comprehensive gas chromatography.

Luca Nicolotti et al.

Journal of chromatography. A, 1360, 264-274 (2014-08-19)

Comprehensive two-dimensional gas chromatography (GC×GC) coupled with Mass Spectrometry (MS) is one of today's most powerful analytical platforms for detailed analysis of medium-to-high complexity samples. The column set usually consists of a long, conventional-inner-diameter first dimension ((1)D) (typically 15-30m long

Bio-degradation of acetates of geraniol, nerol & citronellol by P. incognita: isolation & identification of metabolites.

K M Madyastha et al.

Essential role for SNMP1 in detection of sex pheromones in Helicoverpa armigera.

Shuai Liu et al.

Insect biochemistry and molecular biology, 127, 103485-103485 (2020-10-14)

The sensory neuron membrane protein, SNMP1, was initially discovered in moths and is associated with sex pheromone sensitive neurons, suggesting a role in the detection of these semiochemicals. Although DrosophilaSNMP1 has been reported to be involved in detecting of the

Pesticide determination in rose petals using dispersive solid-phase extraction followed by gas chromatography-tandem mass spectrometry.

Oriane Tascone et al.

Analytical and bioanalytical chemistry, 406(30), 8041-8048 (2014-10-27)

Damascena and centifolia roses are cultivated worldwide for their petal extracts that contain key odorant ingredients of perfumes. The analytical identification and quantification of pesticides in rose petals have never been described in the literature. Here, we report on a

Nanogram-scale preparation and NMR analysis for mass-limited small volatile compounds.

Satoshi Nojima et al.

PloS one, 6(3), e18178-e18178 (2011-04-06)

Semiochemicals are often produced in infinitesimally small quantities, so their isolation requires large amounts of starting material, not only requiring significant effort in sample preparation, but also resulting in a complex mixture of compounds from which the bioactive compound needs

Variation of the chemical composition and antimicrobial activity of the essential oils of natural populations of Tunisian Daucus carota L. (Apiaceae).

Nesrine Rokbeni et al.

Chemistry & biodiversity, 10(12), 2278-2290 (2013-12-12)

The essential oils of Daucus carota L. (Apiaceae) seeds sampled from ten wild populations spread over northern Tunisia were characterized by GC-FID and GC/MS analyses. In total, 36 compounds were identified in the D. carota seed essential oils, with a

Comparison of aroma active and sulfur volatiles in three fragrant rice cultivars using GC-olfactometry and GC-PFPD.

Kanjana Mahattanatawee et al.

Food chemistry, 154, 1-6 (2014-02-13)

Aroma volatiles from three cooked fragrant rice types (Jasmine, Basmati and Jasmati) were characterised and identified using SPME GC-O, GC-PFPD and confirmed using GC-MS. A total of 26, 23, and 22 aroma active volatiles were observed in Jasmine, Basmati and

Behavior of Multiclass Pesticide Residue Concentrations during the Transformation from Rose Petals to Rose Absolute.

Oriane Tascone et al.

Journal of agricultural and food chemistry, 63(20), 4922-4932 (2015-05-06)

This study investigates the concentrations of 54 multiclass pesticides during the transformation processes from rose petal to concrete and absolute using roses spiked with pesticides as a model. The concentrations of the pesticides were followed during the process of transforming

Potential of hydrocarbon and oxygenated monoterpenes against Culex pipiens larvae: Toxicity, biochemical, pharmacophore modeling and molecular docking studies.
