Abstract Bemisia tabaci (whitefly) infestations and the subsequent transfer of viruses are cause severe losses in crop production horticultural practice. To improve biological control B. tabaci, we investigated repellent properties plant-produced semiochemicals. The mix headspace volatiles, collected from naturally wild tomato accessions, influenced initial choice behavior, indicating a role for plant semiochemicals locating host plants. A collection accessions introgression lines (Solanum...
• Since the 1970s it has been known that nursery pollinator Hadena bicruris is attracted to flowers of its most important host plant, Silene latifolia, by their scent. Here we identified compounds for attraction this noctuid moth. Gas chromatographic and electroantennographic methods were used detect eliciting signals in antennae Electrophysiologically active tested wind-tunnel bioassays foraging naïve moths, attractivity these was compared with natural scent whole S. latifolia flowers. The...
We theoretically investigate charge transport through electronic bands of a mesoscopic one-dimensional system, where interband transitions are coupled to confined cavity mode, initially prepared close its vacuum. This coupling leads light-matter hybridization the dressed fermionic interact via absorption and emission photons. Using self-consistent nonequilibrium Green's function method, we compute transmissions photon spectra demonstrate how can lead an enhancement conductivity in steady...
Chemoreception is based on the senses of smell and taste that are crucial for animals to find new food sources, shelter, mates. The initial step in olfaction involves translocation odorants from periphery through aqueous lymph olfactory sensilla odorant receptors most likely by chemosensory proteins (CSPs) or binding (OBPs). To better understand roles CSPs OBPs a coleopteran pest species, red flour beetle Tribolium castaneum (Coleoptera, Tenebrionidae), we performed transcriptome analyses...
Abstract An olfactory biosensor based on a reduced graphene oxide (rGO) field‐effect transistor (FET), functionalized by the odorant‐binding protein 14 (OBP14) from honey bee ( Apis mellifera ) has been designed for in situ and real‐time monitoring of broad spectrum odorants aqueous solutions known to be attractants bees. The electrical measurements binding all tested are shown follow Langmuir model ligand–receptor interactions. results demonstrate that OBP14 is able bind even after...
We study a disordered ensemble of quantum emitters collectively coupled to lossless cavity mode. The latter is found modify the localization properties ``dark'' eigenstates, which exhibit character being localized on multiple noncontiguous sites. denote such states as semilocalized and characterize them by means standard measures. show that those can very efficiently contribute coherent energy transport. Our paper underlines important role dark in systems with strong light-matter coupling.
In many insect species olfaction is a key sensory modality. However, examination of the chemical ecology insects has focussed up to now on living above ground. Evidence for behavioral responses cues in soil other than CO2 scarce and role played by process finding host roots below ground not yet understood. The question whether soil-dwelling beetle larvae can smell their plant been under debate, but proof as lacking that olfactory perception volatile compounds released damaged plants, known...
We study the interplay between charge transport and light-matter interactions in a confined geometry by considering an open, mesoscopic chain of two-orbital systems resonantly coupled to single bosonic mode close its vacuum state. introduce benchmark different methods based on self-consistent solutions nonequilibrium Green's functions numerical simulations quantum master equation, derive both analytical results. It is shown that dissipative regime where cavity photon decay rate largest...
Light-matter interactions have generated considerable interest as a means to manipulate material properties. Light-induced superconductivity has been demonstrated using pulsed lasers. An attractive alternative possibility is exploit strong light-matter arising by coupling phonons the vacuum electromagnetic field of cavity mode suggested and theoretically studied. Here we explore this for two very different superconductors, namely YBCO (YBa$_2$Cu$_3$O$_{6+x}$) Rb$_3$C$_{60}$, coupled surface...
We describe the fabrication and performance of a biosensor for odorants, using wildtype engineered mutants Italian honeybee (Apis mellifera ligustica) odorant binding protein 14 (OBP14), immobilized onto reduced graphene oxide field-effect transistor (rGO-FET). The properties when on are similar to those measured in solution, thus providing method measuring affinities small molecules as an alternative current fluorescence assay. Out chemicals tested, best ligands OBP14 were eugenol,...
Cis boleti (Coleoptera: Ciidae) preferentially colonizes fungi from the genus Trametes that are known as important wood decomposers. The aim of our research was to investigate if C. uses chemical volatile composition its fungal host, gibbosa, a key attraction factor. Therefore, T. gibbosa fruiting body volatiles were analysed by using gas chromatography–mass spectrometry, with parallel electroantennographic detection (GC-MS/EAD) adults boleti. Furthermore, we examined behavioral responses...
Abstract Volatiles emitted by decaying human remains are in the focus of recent research. The identification core volatiles this field is high importance, because cadaveric generally show variation. In study, volatile profiles five mice ( Myodes glareolus ) were sampled with charcoal filter tubes from their time death until advanced decay. Eleven compounds quantitated means gas chromatography–mass spectrometry. Electroantennographic experiments female C alliphora vicina antennae led to...
Abstract This study aimed at correlating selected carcass borne volatile organic compounds (VOCs) with the postmortem interval (PMI). Selected volatiles should 1st be reliably emitted during vertebrate decay, 2nd high concentrations, and 3rd show a reproducible quantitative dynamic decaying process. Four pigs ( S us scrofa domesticus L .) were placed in deciduous forest different seasons process sampled. Seventeen identified quantified by GC ‐ MS . Electrophysiological experiments on antenna...
Abstract The red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) is the most encountered and destructive stored product insect pest of cereal grains seeds. Although this has been used as a model organism for many decades, there no systematic knowledge about antennal detection host non‐host volatiles. Electroantennogram responses to 94 selected volatile organic compounds including alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, terpenoids aromatic...
