Since chemosensory genes play key roles in insect behaviour, they can potentially be used as new targets for pest control. The cabbage beetle, Colaphellus bowringi, is a serious insect pest of cruciferous vegetables in China and other Asian countries. However, a systematic identification of the chemosensory genes expressed in the antennae has not been reported. We assembled the antennal transcriptome of C. bowringi by using Illumina sequencing technology and identified 104 candidate chemosensory genes by analyzing transcriptomic data, which included transcripts encoding 26 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), four sensory neuron membrane proteins (SNMPs), 43 odorant receptors (ORs), nine ionotropic receptors (IRs), and ten gustatory receptors (GRs). The data obtained are similar to those found in other coleopteran species, suggesting that our approach successfully identified the chemosensory genes of C. bowringi. The expression patterns of 43 OR genes, some of which were

Olfaction presents the ultimate challenge to molecular recognition as thousands of molecules have to be recognized by far fewer olfactory receptors. We have presented evidence that Drosophila readily distinguish odorants based on their molecular vibrations using a battery of behavioral assays suggesting engagement of a molecular vibration-sensing component. Here we interrogate electrophysiologically the antennae of four Drosophilids and demonstrate conserved differential response amplitudes to aldehydes, alcohols, ketones, nitriles and their deuterated isotopologues. Certain deuterated odorants evoked larger electroantennogram (EAG) amplitudes, while the response to the normal odorant was elevated in others. Significantly, benzonitrile isotopologues were not distinguishable as predicted. This suggests that isotopologue-specific EAG amplitudes result from differential activation of specific olfactory receptors. In support of this, odorants with as few as two deuteria evoke distinct EAG amplitudes ...

An ablation treatment apparatus has a multiple antenna device with a primary antenna and a secondary antenna. The secondary antenna is positioned in a lumen of the primary antenna as the primary antenna is introduced through tissue to a selected tissue site. At the tissue site the secondary antenna is deployed from the primary antenna in a lateral direction relative to a longitudinal axis of the primary antenna. At least a portion of a distal end of the secondary antenna is structurally less rigid than the primary antenna. The primary antenna is constructed to be rigid enough to be introduced and advanced through tissue. A cable couples the energy source to one or more of the antennas.
Here is the practical method. I just scribbled it on my iPad. You may download it as a PDF file. :-)" - Thierry. Thierry, I have seen something similar to this (The EPE-2008 theremin had a on-board circuit to assist tuning) - but, in playing with the EPE circuit, I found the operation of this circuit unsatisfactory.. My understanding (and my experiments) indicate that maximum loading on the oscillator occurs at the resonant frequency of the antenna circuit (coils + antenna capacitance).. and that one wants the hand capacitance "seen" by the antenna to be at the position one requires for the null point (about 60cm from the antenna). The resistance inserted between the oscillator and antenna circuit allows the oscillator frequency to be adjusted without being effected by the antenna loading - so one can find (by looking for peak current) the resonant frequency of the antenna circuit.. However, as soon as the 100k (or whatever value is used to isolate the antenna from the oscillator) is replaced ...

A passive reflective antenna located near an active receiving antennas is used to change the energy at the receiving antenna. The change in energy may be such as to remove a null created by multipath or to provide directionality, or both. The receiving antennas is permanently connected to a single receiver. When the receivers output signal degrades below an acceptable level of quality, the reflective phase of the passive antennas load is changed to change the phase of the reflected energy and achieve a desired effect (remove a null, change directionality, etc.) at the receiving antenna. In the simplest embodiment, the termination of the passive antenna is switched from an open circuit to a short circuit, or vice versa, to invert the phase of the reflected energy. The use of reflective elements in antenna designs, usually to achieve directionality, is well known (see the common Yagi or corner reflector antenna designs, for example), but these use passive reflector elements.

The antennal lobe is the deutocerebral neuropil of insects which receives the input from the olfactory sensory neurons on the antenna. Functionally, it shares some similarities with the olfactory bulb in vertebrates.. In insects, the olfactory pathway starts at the antennae (though in some insects like Drosophila there are olfactory sensory neurons in other parts of the body) from where the sensory neurons carry the information about the odorant molecules impinging on the antenna to the antennal lobe.[1] The antennal lobe is composed of densely packed neuropils, termed glomeruli, where the sensory neurons synapse with the two other kinds of neurons, the projection neurons and the local neurons.[1] There are 43 glomeruli in the Drosophila antennal lobe; in Aedes aegypti there are 32;[1] locusts and social wasps may have over 1000.[1] The projection neurons project to higher brain centers such as the mushroom body and the lateral horn.[2] [3] [4] The local neurons, which are primarily inhibitory, ...

A system and method are described for using RFID tags to track and monitor personnel and equipment in large environments and environments that are prone to multipath fading. The system scans the environment by selecting local interrogation zones where RFID tags may be located. Multiple antennae are used, each transmitting a portion of an activation signal, such that the activation signal will be formed in the selected local interrogation zone. Different subsets of the antennae are successively selected, each targeting the selected local interrogation zone, to repeat the activation signal for each subset of antenna. RFID tags in the local interrogation zone will receive the portions of the activation signals and process them to determine whether the full activation signal was destined for that local interrogation zone for each of the subsets of antennae. An activated RFID tag will transmit its tag information, including any data collected from sensors connected to the tag, back to the system. The systems
An antenna circuit to be used in conjunction with a chip transponder such that the antenna circuit serves for both the reception of interrogative signals intended for the transponder as well as for response signals that ape to be transmitted by the transponder. The antenna circuit has at least one magnetic circuit of high μ material, and is formed of ceramic core means, that have been built into a depression in a thick-walled surface intended to receive the chip transponder. This thick-walled surface may be of metal. The ceramic core means comprise at least a ceramic core resonator and half a ceramic core that functions as an antenna with its open side facing outward. In one aspect, the ceramic core resonator and the half ceramic core antenna are coupled by means of one or more secondary coils of the closed ceramic core, which also form the coils of the half ceramic core antenna. In another aspect, the secondary coil forms a resonating circuit with at least one capacitive element in series. In yet
Citation: Byers, J.A. 2013. Modeling and regression analysis of semiochemical dose-response curves of insect antennal reception and behavior. Journal of Chemical Ecology. 39(8):1081-1089. Interpretive Summary: Semiochemicals are released by organisms that when perceived by another organism cause it to change behavior. Insects use semiochemicals for communication, to find mates, or to locate or assess host plants. Many insect species have been studied to determine the relationship between concentration (dose) of a specific semiochemical and the corresponding insect behavioral response. Although it is generally recognized that these dose-response relationships are not linear, little information exists to indicate the true functional relationship between semiochemical dose and insect response. A computer simulation using a hypothetical insect antenna and a wide range of semiochemical doses indicated a family of mathematical equations, or functions, described the dose-response relationship nearly ...
A device and method is disclosed for creating a lesion in nerve-containing tissue spaced from a body lumen while protecting tissue forming and adjacent to a wall of the body lumen from injury. A catheter carrying a microwave antenna is positioned within the body lumen. Cooling fluid is circulated around the microwave antenna in thermal contact with the wall of the body lumen. Power is supplied to the microwave antenna to cause microwave energy to be emitted omnidirectionally from the microwave antenna. The power supplied to the microwave antenna and the cooling fluid circulated around the microwave antenna are controlled to cause the nerve-containing tissue spaced from the body lumen to be heated to a temperature sufficient to cause thermal damage while the tissue forming and adjacent to the wall of the body lumen is maintained at a temperature where thermal damage does not occur.
The other problem is the science. Every year we are told that eating foods containing nutrient X is really, really, bad for us, and its a wonder our ancestors survived long enough to reproduce. And then a year or two later, we find out that, fancy that, nutrient X is actually necessary for optimal functioning and we have to start adding it back in. This years must eat food also turns out to be next years you-really-need-to-cut-back-on food. Look at butter vs. margarine. Unless you have a lactose issue, butter has no more calories, and not having tons of weird chemicals, its much, much healthier.

The antennae are 11 segmented (including the scape). In side view, the petiole and postpetiole are either low and rounded or barrel-shaped, or the petiole is armed above with 1 to 3 small spines or teeth. The middle and hind legs with greatly swollen femora (and often tibiae as well). The modified petiole (low and rounded or armed with teeth above) and the swollen femora will separate these ants from others in the subfamily Myrmicinae. Heterick (2009) - Medium-sized ants with rather long, low petioles, which are sometimes armed with small spines or denticles.

A stacked patch antenna has a first element having a feed thereto spaced above a ground plane and one or more spaced apart parasitic elements spaced above the first element. The first and parasitic elements may be tuned to a fundamental mode for radiation of a specified frequency. The geometric centers of the parasitic elements are offset from one another and from the geometric center of the first element along the same direction. The stacked patch configuration provides increased gain and bandwidth. The offset configuration determines the direction of maximum gain for the antenna. The first and parasitic elements can be single antenna elements and may be microstrip antenna elements. The elements can also be arrays of microstrip antenna elements. The phasing of the arrays of microstrip elements can be controlled to determine a gain sensitivity direction.

Consider that you may have a card putting 15dBm (32mW) into a 2.2dBi antenna (on the AP), and thatyour card probably has an effective 2dBi gain antenna on it. Operating at 2.4GHz, at 1m, thereis 41dB of path loss between the two units. At 2m, youll have another 6dB of path loss, for 47dB.So the signal leaves at 17dBm (from the AP), you lose 41dB due to LOS (Line of Sight) path lossat 1m, and the signal arrives at the antenna in your laptop at perhaps -24dBm, and is raisedto -22dBm by the antenna.This is quite close to the maximum signal level of 802.11g ...

Desaturation of fatty acids is a key reaction in the biosynthesis of moth sex pheromones. The main component of Spodoptera littoralis sex pheromone blend is produced by the action of delta11 and delta9 desaturases. In this article, we report on the cloning of four desaturase-like genes in this species: one from the fat body (Sls-FL1) and three (Sls-FL2, Sls-FL3 and Sls-FL4) from the pheromone gland. By means of a computational/phylogenetic method, as well as functional assays, the desaturase gene products have been characterized. The fat body gene expressed a delta9 desaturase that produced (Z)-9-hexadecenoic and (Z)-9-octadecenoic acids in a (1:4.5) ratio, whereas the pheromone gland Sls-FL2 expressed a delta9 desaturase that produced (Z)-9-hexadecenoic and (Z)-9-octadecenoic acids in a (1.5:1) ratio. Although both delta9 desaturases produced (Z)-9-tetradecenoic acid from myristic acid, transformed yeast grown in the presence of a mixture of myristic and (E)-11-tetradecenoic acids produced ...
Insect antennae are multimodal sensory structures that provide olfactory, mechanosensory, hygrosensory and thermosensory information to the insect nervous system (Schneider, 1964). These sensory inputs guide insect flight in several ways. On the shorter (approximately single wing stroke) time scales, antennal mechanosensory feedback is thought to be of key importance for flight control in both non-Dipteran (e.g. Gewecke et al., 1974; Sane et al., 2007; Sane et al., 2010) and Dipteran (Gewecke and Schlegel, 1970; Mamiya et al., 2011) insects, whereas on the longer (of the order of multiple wing strokes) time scales feedback from other modalities such as vision and olfaction also influences their overall flight trajectories (Kennedy and Marsh, 1974; Willis and Arbas, 1991; Willis and Arbas, 1998; Verspui and Gray, 2009; Vickers, 2000). The central processing of mechanosensory and olfactory inputs is clearly separated within the insect deutocerebrum. Whereas the olfactory input is primarily ...
Antenna gain-to-noise-temperature (G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and the RF chain noise temperature from the antenna terminals to the receiver output. Antenna temperature (Tant) is a parameter that describes how much noise an antenna produces in a given environment. Antenna noise temperature is not the physical temperature of the antenna but rather an expression of the available noise power at the antenna flange. Moreover, an antenna does not have an intrinsic "antenna temperature" associated with it; rather the temperature depends on its gain pattern and the thermal environment that it is placed in. Antenna temperature is also sometimes referred to as Antenna Noise Temperature. To define the environment, well introduce a ...

During contact, antennal bending is determined by its flexural stiffness and the applied load. From estimates of the second moment of area and measurements of the resistance-to-bending forces along the flagellum, we determined that the flexural stiffness of the cockroach antennal flagellum decreases rapidly from base to tip (Fig. 1A-C). We found that the forces decreased exponentially, whereas the elastic modulus did not change significantly within the measured length, suggesting that geometrical properties, i.e. tapering, are the main determinant of flexural stiffness (Fig. 1D).. Using a physical model of an arthropod antenna, we tested the hypotheses that a decreasing flexural stiffness profile enables effective mapping of the point of bend and/or point of contact to body-to-wall distance and increases the preview distance. By testing different stiffness profiles, we found that the point of bend maps better to the body-to-wall distance for a decreasing stiffness compared with a constant ...
Thanks for the additional information Becky. The segmented antennae are a very good indication this is a beetle. At first glance we thought it was a True Bug, but the antennae structure overrules that.

Images on iSpot and Africa Wild are also a very good visual match to your image ...
Its a bit wet out this morning, so I did not get a chance to spend as much time out back as in previous days. Todays count is four, yesterdays was 12. Ive been watching some videos of Monarch caterpillars molting at You Tube and also some time reading a bit about the different instars. I think the caterpillars in the photo attached are second instar. Im no expert, and it is wet out there, but I think the one on the left may have just molted. Their antennae are definitely longer today than yesterday when they were just little horns. Waste not, want not, Ive read that they eat their old skin. Ill check a little later on to see if that bit of junk just below the caterpillar on the left is gone ...
Larvae: A common characteristic of species in the subgenus Melanoconion is that the larval head is wider than long and the thorax is the same size as the head (Foote 1952). The abdomen has eight segments, the siphon, and the saddle. The first two abdominal segments are two times as wide as they are long. The remaining segments taper to the siphon and the saddle (Foote 1952). In Culex iolambdis larvae the antennae are almost as long as the head (Carpenter and LaCasse 1955). The siphon is five times as long as it is wide, with a black band one-third of the way down the siphon (Pratt and Seabrook 1952), and a row of pectin spines occurs from the base of the siphon for approximately one-third the length of the siphon (Darsie and Ward 2005, Pratt and Seabrook 1952). Beyond the row of pectin spines, five pairs of long-barbed tufts of setae occur. There is a dark scleritized plate on segment X (Pratt and Seabrook 1952) and at the end of the saddle there are four anal papillae that are shorter than the ...
Fish lice species vary in size from just a few millimetres to over 30 millimetres (1.2 in) long, with females usually somewhat larger than the males. There are many species and they are present throughout the world, some having been introduced to the west from Asia with consignments of fancy fish in the early 20th century.. Almost all species in the family are external parasites of fish, with a few species that parasitise on invertebrates or amphibians. They have a wide flattened, oval body, almost entirely covered by a carapace. Their compound eyes are prominent, and the mouth and the first pair of antennae are modified to form a hooked, spiny proboscis (stylet) equipped with suckers, as an adaptation to parasitic life. They have four pairs of thoracic appendages, which are used to swim when they release from the fish. They leave the host for up to three weeks in order to mate and lay eggs. The eggs are laid in strings and patches of jelly on stones and hatch into parasitic larvae.. Affected ...

The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp., in the USA. Although the assumption that phorid flies use fire ant alarm pheromones for host location is probably true, we demonstrated in a previous study the possible involvement of other ant semiochemicals in the response of P. tricuspis to fire ants. This study was conducted to determine the glandular sources and identity of the semiochemicals mediating this interaction. First, we tested the electroantennogram response of P. tricuspis to extracts of key body parts and glands of workers of the red imported fire ant, S. invicta Buren. The results confirm that the poison (venom) gland/sac is the key source of compounds which elicited strong antennal activity in P. tricuspis. Follow-up studies were conducted by using a combination of bioassay-guided fractionation and behavioral bioassays to test the hypothesis that attraction of this parasitoid to fire ants is mediated by venom alkaloids.
The most abundant volatile organic compounds (VOC) from chestnut reproductive plant tissue (catkin, nut and bur) were identified with gas chromatography and mass-spectrometry (GC-MS). Two-choice behavioral bioassays were conducted with a Y-tube olfactometer using chestnut plant tissues (leaf, catkin, nut and bur) and individual VOC to assess the response of adult lesser chestnut weevil, Curculio sayi. Additionally, the electrophysiological response of the antennae of C. sayi adults towards both plant tissue and individual VOC from chestnut was examined using an electroantennogram (EAG). The behavioral bioassay and EAG data associated with chestnut plant tissue demonstrated that the insect does not respond directly to the sites of oviposition (nut tissue), but rather more strongly to the spiked bur encasing the nuts, the leaves, and the spring florescence (catkins). There were several differences between male and female responses to plant tissue and individual VOC, as well as significant ...

The "Cancer Cell Biology and Translational Research" section focuses on understanding the basic biological processes involved with a normal cell transforming into a cancerous one. By understanding these mechanisms, potential therapeutic interventions may be envisioned. We continue investigating the role of the primary cilium in tumor biology.. Primary cilia are multisensory organelles - similar to a cell antenna - that sense and receive signals from the environment surrounding the cells. Weve found that these antennae are lost in tumor cells; therefore, we are trying to understand the mechanisms of ciliary loss, and what are the consequences of such a loss. Furthermore, as we gain knowledge on these mechanisms, we are now able to induce the restoration of primary cilia in tumor cells and bring back the malignant cells to a more normal phenotype, which may contribute to the development of new therapeutic strategies based on the rescue of primary cilia integrity.. Our research is focused on ...

LeConte (1876) diagnosed this relatively small species as one in which the underlying cuticle is black and covered by a thin coat of grey pubescence - Stickland Museum specimens appear to have a much more reddish-brown coat on dorsal surfaces, but this is simply because their emergence coat has not rubbed off yet (Essig, 1958). This species is distinguished by its thick rostrum, which is as long as its prothorax, and bears coarse punctures (laterally), and a prominent fovea (shallow central pit) and shallow transverse depression on its front. Antennae are situated very close to the tip of the rostrum. The overall body shape is relatively ovate (in dorsal view). The prothorax has fairly round sides, is wider than it is long, and has broad indentations in its posterior edge (for accepting leading edges of elytra). These indentations meet along the midline of the prothorax to form a very broad triangle at the medial angle. The legs of this species have femora that are moderately slender and uniform ...
In this paper, efficient, high gain and pencil beam grid antenna array is proposed for hyperthermia breast cancer therapy system. The proposed antenna bandwidth extends from 4.8 GHz to 4.9 GHz at resonant frequency of 4.86 GHz. This frequency band has been reported for the breast cancer hyperthermia therapy. The grid long and short sides are responsible for the undesired cross-polarized radiation and desired copolarized radiation, respectively. The unsuitability of the conventional grid antenna array is ensured by investigating its radiation properties. The proposed grid antenna array short side width is varied and its long side width is kept wide as possible to enhance the radiation properties and to reduce the losses. Also, a reflector has been used for gain enhancement purpose. The proposed grid antenna array achieves side lobe level and 3 dB beam width of -27.9 dB and 25.9° for the E-plane and -27.9 dB and 26.3° for the H-plane, respectively. The breast phantom is irradiated by both

The interest in creating and detecting electromagnetic waves carryingangular momentum in such a way that they form helical wavefronts,so called "twisted light, has increased in recent decades.One possible way of generating such waves at radio frequenciesis to use a circular phased antenna array, where a larger relativephasing of the antenna elements corresponds to more twist of thewavefront per wavelength.However, analytical computations of the radiated power, and in turn theamountof emitted angular momentum, displays a quite rapid decrease with increasedphasing. This decrease in intensity may cause problems when alarge range of twisting is desired; for instance, as a means to encodeand transmit information. We have found that the decrease in radiatedpower does not haveany explicit relation to the beam being endowed with angular momentum.Instead, the decrease in emitted power can be explained byelectromagnetic couplingof the antenna elements in the array and that energy conservationholds, ...
While scientists have been tinkering with the genes of insects such as fruit flies for a long time, ants have proven to be a bigger challenge. In order to perform germline editing-genetic changes passed through generations-scientists have to modify the queen ant who lays the eggs. But there are some types of ants, such as clonal raiders, that reproduce asexually and without fertilization, producing clones of the mothers. Despite the trickiness, researchers at two different institutions recently succeeded in mutating ants. A study in Cell details how researchers genetically modified clonal raider ants using CRISPR, a gene-editing technique that allows for the cutting and/or pasting of gene sequences. In this study, scientists deactivated the orco gene, which facilitates the proper functioning of ants odorant receptors. When ants odorant receptors are disrupted, all of their olfactory genes suffer. Those receptors are crucial to ants social behavior-pheromones dictate how ants live and work ...

Plasticity in the honeybee brain has been studied using the appetitive olfactory conditioning of the proboscis extension reflex, in which a bee learns the association between an odor and a sucrose reward. In this framework, coupling behavioral measurements of proboscis extension and invasive recordings of neural activity has been difficult because proboscis movements usually introduce brain movements that affect physiological preparations. Here we took advantage of a new conditioning protocol, the aversive olfactory conditioning of the sting extension reflex, which does not generate this problem. We achieved the first simultaneous recordings of conditioned sting extension responses and calcium imaging of antennal lobe activity, thus revealing on-line processing of olfactory information during conditioning trials. Based on behavioral output we distinguished learners and non-learners and analyzed possible learning-dependent changes in antennal lobe activity. We did not find differences between glomerular

The development of olfactory glomeruli has been studied particularly heavily in the antennal lobe of the moth Manduca sexta. In the current study, we address the development of synapses within the antennal lobe of M. sexta by reporting on the localization of synaptotagmin, a ubiquitous synaptic vesicle protein, throughout development. A cDNA clone coding for M. sexta synaptotagmin was characterized and found to encode a protein that shares 67% amino acid identity with Drosophila synaptotagmin ...
The ant Cataglyphis lives in the Sahara desert and is one of the most thermotolerant land animals known. It forages at body temperatures above 50 degrees C, and the critical thermal maxima are at 53.6 +/- 0.8 degrees C for Cataglyphis bombycina and 55.1 +/- 1.1 degrees C for Cataglyphis bicolor. The synthesis and accumulation of heat shock proteins (HSPs) were analyzed in Cataglyphis and compared to Formica, an ant living in more moderate climates, and to two Drosophila species. In Cataglyphis, protein synthesis continues at temperatures up to 45 degrees C as compared to 39 degrees C for Formica and Drosophila. The two Drosophila species, Drosophila melanogaster and Drosophila ambigua, differ with respect to their maximal induction of HSP synthesis and accumulation by 3-4 degrees C. In contrast, the two ant species accumulate HSPs prior to their exposure to heat, and in Cataglyphis the temperature of maximal HSP induction by de novo protein synthesis is only 2 degrees C higher than in Formica. ...

DEET (N,N-diethyl-meta-toluamide) is the worlds most widely used topical insect repellent, with broad effectiveness against most insects. Its mechanism of action and molecular target remain unknown. Here, we show that DEET blocks electrophysiological responses of olfactory sensory neurons to attractive odors in Anopheles gambiae and Drosophila melanogaster. DEET inhibits behavioral attraction to food odors in Drosophila, and this inhibition requires the highly conserved olfactory co-receptor OR83b. DEET inhibits odor-evoked currents mediated by the insect odorant receptor complex, comprising a ligand-binding subunit and OR83b. We conclude that DEET masks host odor by inhibiting subsets of heteromeric insect odorant receptors that require the OR83b co-receptor. The identification of candidate molecular targets for the action of DEET may aid in the design of safer and more effective insect repellents. |P /|
