Full textAbstract:
Outreach insect drawers serve as valuable educational tools, showcasing insect diversity and fostering curiosity. However, these static displays often fail to bridge the emotional gap between people and insects. Here, I discuss how by incorporating live insects, namely male bumble bees and carpenter bees, into outreach events might help to reduce fear and foster empathy amongst the public. I argue that, by integrating live insects with traditional displays, we can inspire deeper connections and encourage conservation efforts, ensuring that people see insects as living organisms worth protecting, rather than just specimens behind glass. Future research questions and suggestions regarding evaluation of outreach collections are discussed.

Over the past two decades, natural history collections (NHCs) have played an increasingly prominent role in global change research, but they have still greater potential, especially for the most diverse group of animals on Earth: insects. Here, we review the role of NHCs in advancing our understanding of the ecological and evolutionary responses of insects to recent global changes. Insect NHCs have helped document changes in insects' geographical distributions, phenology, phenotypic and genotypic traits over time periods up to a century. Recent work demonstrates the enormous potential of NHCs data for examining insect responses at multiple temporal, spatial and phylogenetic scales. Moving forward, insect NHCs offer unique opportunities to examine the morphological, chemical and genomic information in each specimen, thus advancing our understanding of the processes underlying species’ ecological and evolutionary responses to rapid, widespread global changes. This article is part of the theme issue ‘Biological collections for understanding biodiversity in the anthropocene’.

The Invertebrate Paleontology Collection at the Natural History Museum of Los Angeles County (NHMLA) has received support from the United States National Science Foundation (NSF DBI 1702342) to digitize the museum’s unique and historic collection of 28,000+ fossil insects. The primary goal of this project, “Fossil Insects of L.A.”, is to increase access to these collections for both research and education. Key collections to be become discoverable through iDigBio and iDigPaleo include the Georg Statz Collection (Oligocene, Rott Formation, Germany) and three faunas from Southern California: Barstow (Miocene), Rancho La Brea (Pleistocene), and McKittrick (Pleistocene). Fossil Insects of L.A. constitutes the final contribution to the Fossil Insect Collaborative Thematic Collections Network (TCN), a consortium of institutions that have been digitizing the largest fossil insect collections in the United States. As a project beginning at the tail-end of the TCN’s active funding, Fossil Insects of L.A. is actively leveraging existing TCN knowledge and resources to streamline workflows and efficiently achieve project goals. In addition to basing imaging and preservation protocols on those designed by TCN partners, Fossil Insects of L.A. is using a layered approach to provide high-quality taxonomic information without sacrificing the pace of specimen digitization. Previously unidentified specimens are initially identified only to Order, allowing them to quickly continue through the digitization process; specimens can then be re-examined by experienced project participants and external experts, who are able to reference the specimen images generated during digitization. A critical and novel aspect of this component of the project’s workflow is the concurrent digitization of the literature associated with the Statz Collection. These data will be used as a test case for the "Enhancing Paleontological and Neontological Data Discovery API" (ePANDDA) project (NSF ICER 1821039), which seeks to associate related datasets found in iDigBio, iDigPaleo, and the Paleobiology Database. Fossil Insects of L.A. will digitize and make 10,960 specimens publically available online, of which over 6,200 will include images. An additional 15,684 specimen records from the Rancho La Brea Tar Pits will also be included in the data mobilization. In doing so, Fossil Insects of L.A. intends to dramatically enhance the research potential of these formerly hidden collections, as well as synthesize and demonstrate digitization best practices generated through the TCN.

Full textAbstract:
The previous species list of South African Mantodea, published in 1998, was largely compiled from the literature and did not incorporate data from the many insect museum collections available in the country. It is estimated that approximately 120 species of Mantodea occur in South Africa; however, since no historical museum records were previously incorporated, the current information is considered to be outdated and not a true reflection of the Mantodea fauna within this region. A checklist of species is an important benchmark for any insect group, especially in light of the worldwide declines of insect diversity reported over the last decade. Checklists that provide accurate information on insect diversity, especially for groups, such as the Mantodea which could be under threat and thus could provide important information that can be used in determining the threat status of species, as well as to aid in their conservation in general.This paper provides an updated checklist of the praying mantids (Insecta, Mantodea) species of South Africa. While 120 species were previously reported to occur in South Africa, this paper reports 157 species in 64 genera that represent eight different superfamilies, 14 families and 22 subfamilies. Additionally, five species are reported for the first time to occur in South Africa. This species list was generated from the approximately 4000 specimen records of which 3558 records reside within South Africa. The remaining 732 records represent 14 other African countries. Occurrence records from two citizen-science platforms (iNaturalist and Gbif.org), were also incorporated in this study, adding 1880 species records in South Africa. The low number of specimens in the national collections indicate that this group of insects is poorly collected and highlights the lack of knowledge about South Africa's mantid fauna, as well as a lack of taxonomic expertise as 1532 museum specimens remain unidentified to species level.

Full textAbstract:
Museums from six African countries (Botswana, Kenya, Zimbabwe, South Africa, Madagascar, Mozambique), with support from the California Academy of Sciences, are currently collaborating on the GBIF funded project: African Insect Atlas: unleashing the potential of insects in conservation and sustainability research in Africa (BID-AF2015-0134-REG). This project was initiated to move biodiversity knowledge out of insect collections into the hands of a new generation of global biodiversity researchers interested in direct outcomes. The project acknowledges that insects are the glue that hold ecosystems together, and are ideal organisms for climate change biology, conservation planning, mapping local and regional patterns of diversity, and monitoring threats to ecosystem services and natural capital, thereby addressing the Sustainable Development Goal #15, 'Life on Land (http://www.undp.org/content/undp/en/home/sustainable-development-goals.html). The consortium partners have, since June 2016, embarked on a journey to learn digitization techniques and have successfully digitized 50% of the project goals. The targeted insect orders include Coleoptera, Odonata, Ephemeroptera, Plecoptera, Trichoptera and Hymenoptera. The data being mobilized includes specimen and species data, habitat information as well as identification of possible threats such as deforestation. These are being captured into a standardized platform using Darwin Core. Elaborate data cleaning is being carried out using tools in OPEN Refine (http://openrefine.org) and Microsoft Excel 2010. The captured data is also being geo-referenced using appropriate software such as GEOLocate (http://www.museum.tulane.edu/geolocate) and GEO-Calculator (http://manisnet.org/gci2.html). The specimen occurrence records will be made available on the GBIF platform and will continuously be updated as more information becomes available. Any specimen images taken will also be linked to the database (SPECIFY and Microsoft Excel). Assessments will be carried out to establish which species are native and endemic as well as to establish their conservation status. Simplified image catalogues, checklists, distribution and habitat maps in suitable formats will also be produced to help scientists and other users to identify these species during their research and in the field.

Full textAbstract:
Digitisation of natural history collections draws increasing attention. The digitised specimens not only facilitate the long-term preservation of biodiversity information but also boost the easy access and sharing of information. There are more than two billion specimens in the world's natural history collections and pinned insect specimens compose of more than half of them (Tegelberg et al. 2014, Tegelberg et al. 2017). However, it is still a challenge to digitise pinned insect specimens with current state-of-art systems. The slowness of imaging pinned insects is due to the fact that they are essentially 3D objects and associated labels are pinned under the insect specimen. During the imaging process, the labels are often removed manually, which slows down the whole process. How can we avoid handling the labels pinned under often fragile and valuable specimens in order to increase the speed of digitsation? In our work (Saarenmaa et al. 2019) for T3.1.2 task in the ICEDIG (https://www.icedig.eu) project, we first briefly reviewed the state-of-the-art approaches on small insect digitisation. Then recent promising technological advances on imaging were presented, some of which have not yet been used for insect digitisation. It seems that one single approach will not be enough to digitise all insect collections efficiently. The approach has to be optimized based on the features of the specimens and their associated labels. To obtain a breakthrough in insect digitisation, it is necessary to utilize a combination of existing and new technologies in novel workflows. To explore the options, we identified six approaches for digitising pinned insects with the goal of minimum manipulations of labels as follows. Minimal labels: Image selected individual specimens without removing labels from the pin by using two cameras. This method suits for small insects with only one or a few well-spaced labels. Multiple webcams: Similar to the minimal labels approach, but with multiple webcams at different positions. This has been implemented in a prototype system with 12 cameras (Hereld et al. 2017) and in the ALICE system with six DSLR cameras (Price et al. 2018). Imaging of units: Similar to the multiple webcams approach, but image the entire unit ("Units" are small boxes or trays contained in drawers of collection cabinets, and are being used in most major insect collections). Camera in robot arm: Image the individual specimen or the unit with the camera mounted at a robot arm to capture large number of images from different views. Camera on rails: Similar to camera in robot arm approach, but the camera is mounted on rails to capture the unit. A 3D model of the insects and/or units can be created, and then labels are extracted. This is being prototyped by the ENTODIG-3D system (Ylinampa and Saarenmaa 2019). Terahertz time-gated multispectral imaging: Image the individual specimen with terahertz time-gated multispectral imaging devices. Experiments on selected approaches 2 and 5 are in progress and the preliminary results will be presented.

Full textAbstract:
InvertNet, one of the three Thematic Collection Networks (TCNs) funded in the first round of the U.S. National Science Foundation’s Advancing Digitization of Biological Collections (ADBC) program, is tasked with providing digital access to ~60 million specimens housed in 22 arthropod (primarily insect) collections at institutions distributed throughout the upper midwestern USA. The traditional workflow for insect collection digitization involves manually keying information from specimen labels into a database and attaching a unique identifier label to each specimen. This remains the dominant paradigm, despite some recent attempts to automate various steps in the process using more advanced technologies. InvertNet aims to develop improved semi-automated, high-throughput workflows for digitizing and providing access to invertebrate collections that balance the need for speed and cost-effectiveness with long-term preservation of specimens and accuracy of data capture. The proposed workflows build on recent methods for digitizing and providing access to high-quality images of multiple specimens (e.g., entire drawers of pinned insects) simultaneously. Limitations of previous approaches are discussed and possible solutions are proposed that incorporate advanced imaging and 3-D reconstruction technologies. InvertNet couples efficient digitization workflows with a highly robust network infrastructure capable of managing massive amounts of image data and related metadata and delivering high-quality images, including interactive 3-D reconstructions in real time via the Internet.

I study art, and that is because I like to think about how it helps people learn. In particular I like to create insects as abstractions of nature to invite a different perspective on how the world works. I strive to create synergy through interdisciplinary projects so that people can learn through science, technology and art simultaneously. The point of intersection between these fields of study is where my work can be found. My artwork includes scientific photography of insect collections, 3-D scanning, rapid prototyping, molds and ceramic sculptures. All of these have specific processes and through them I have created abstractions of nature to invite a different perspective.

Full textAbstract:
Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.

Plusieurs thèmes traversent les aspects en apparence si différents de cette recherche : l'insecte d'abord, qui est à l'origine de la démarche plastique et devient l'agent et le guide de notre déambulation dans l'histoire. De petites fabrications dérisoires faites de résidus récoltés au cours d’itinéraires dans Paris, sont à l'origine de multiples questionnements sur l'assemblage. L'institution de quelques règles de fabrication permet, à leur image, de parler essentiellement d'assemblages figuratifs réalisés par récupération d'objets manufacturés. L'entomologie, à la méthodologie si rigoureuse, servira aussi à valider certains principes de classification pour étudier les processus cognitifs et les ressorts associatifs qui président à la création artistique. Toute fabrication, intellectuelle ou tangible, est surdéterminée par les matériaux qui la constitue. Le préalable de ce travail consistera donc à désenchevêtrer le réseau sémantique des notions qui en bâtissent les grandes lignes, comme celles de collection, de classement, de combinaison, ou encore de ressemblance, pour établir qu'il existe un faisceau de relations entre la possibilité même de l'apparition de l'assemblage comme genre référencé et la prise de conscience par la peinture de ses propres enjeux dans une sorte de retour auto-réflexif. La mouche peinte en sera l'annonciatrice emblématique<br>Several themes cross the seemingly so different aspects of this study : first the insect, which is the origin of this artistic research and then becomes the agent and the guide of our wandering through history. Tiny and trivial making made of junks picked up during walks in Paris are the reason for many questionings on the notion of assemblage. The institution of a few making rules allows us, in their image, to talk essentially about figurative assemblages made by the recycling of manufactured objects. Entomology, with its meticulous methodology, will also be used as a tool to validate some classification principles in order to study the cognitive process and the associative resorts which govern artistic creation. Every making, intellectual or tangible, is overdetermined by the materials it is made of. The precondition to this work consists in disentangling the semantic web of notions from which derive the main lines such as collection, classification, combination, or even similarity, to establish that there is a bundle of relation between the very possibility of the emergence of assemblage as a referenced genre and the realization by painting of its own issues, in a sort of self-reflexive turning back. The painted fly will become its emblematic forewarning

Full textAbstract:
In summary the tilting mechanism helps to explain the overall flow structure and the stability of the leading edge vortex.; The leading edge vortex has been identified as the most critical flow structure for producing lift in flapping wing flight. Its stability depends on the transport of the entrained vorticity into the wake via spanwise flow. This study proposes a hypothesis for the generation and enhancement of spanwise flow based on the chordwise vorticity that results from the tilting of the leading edge vortex and trailing edge vortex. We investigate this phenomenon using dynamically scaled robotic model wings. Two different wing shapes, one rectangular and one based on Drosophila melanogaster (fruit fly), are submerged in a tank of mineral oil and driven in a flapping motion. Two separate kinematics, one of constant angular velocity and one of sinusoidal angular velocity are implemented. In order to visualize the flow structure, a novel three dimensional particle image velocimetry system is utilized. From the three dimensional information obtained the chordwise vorticity resulting from the vortex tilting is shown using isosurfaces and planar slices in the wake of the wing. It is observed that the largest spanwise flow is located in the area between the chordwise vorticity of the leading edge vortex and the chordwise vorticity of the trailing edge vortex, supporting the hypothesis that the vortex tilting enhances the spanwise flow. Additionally the LEV on the rectangular wing is found to detach at about 80% span as opposed to 60% span for the elliptical wing. Also, two distinct regions of spanwise flow, one at the base and one at the tip, are observed at the beginning of the sinusoidal kinematic, and as the velocity of the wing increases these two regions unionize into one. Lastly, the general distribution of vorticity around each wing is found to be nearly the same, indicating that different wing shapes do not greatly affect the distribution of vorticity nor stability mechanisms in flapping flight.<br>B.S.<br>Bachelors<br>Mechanical, Materials, and Aerospace Engineering<br>Engineering and Computer Science

En milieu naturel, la vie en société implique que de nombreuses actions, activités ou décisions soient réalisées en groupe.

Pour mener à bien ce travail, nous avons quantifié les réponses individuelles et collectives chez la blatte Periplaneta americana, dans un milieu caractérisé par la présence de sites de repos (de qualité identique ou différente). Il s'agit de comprendre et de caractériser les différentes dynamiques qui, sur base des préférences individuelles pour les différents sites de repos et des interactions sociales, permettent à l'échelle de la population l'émergence d’un choix collectif, et au niveau individuel, à l’exploitation optimale de son environnement. <p><p>Nos résultats ont montré que malgré l'absence de communication ou de perception à longue distance (ex :orientation visuelle, phénomènes de suivi de piste), sans comparaison ni connaissance parfaite du milieu (ex :la localisation et le nombre d’abris ou de congénères) les blattes sont capables de discriminer collectivement entre des alternatives spatialement dispersées et de faire le meilleur choix (associé au maintien de la cohésion). Ce phénomène de choix collectif est un sous-produit des différentes dynamiques agrégatives gouvernées par les compétitions entre processus d’amplification et permet au groupe de résoudre un problème qui est au-dessus des capacités individuelles. Dans nos expériences, cela se manifeste par une double augmentation en fonction de la taille du groupe: (1) un individu tend à s'installer plus souvent dans un site de repos et (2) un individu a plus de chances de se retrouver sous le site de repos optimal. Une analyse plus fine des comportements individuels, rendue possible par l'utilisation de la RFID, a montré qu’au sein des blattes, deux stratégies existaient: les initiateurs et les explorateurs. Enfin, l'utilisation de robots (sociétés mixtes blattes/robots) nous a permis de valider notre modèle théorique mais aussi d’introduire artificiellement des conflits d'intérêt entre les membres du groupes :la présence de ces individus clefs peut modifier la réponse collective de manière dramatique.<p><p>Après avoir comparé nos travaux avec la littérature actuelle, nous avons discuté de la valeur générique de tels processus agrégatifs, prérequis essentiel pour la coordination et la synchronisation des activités des individus.

Full textAbstract:
AbstractIn this conclusion, we revisit some of the key findings of this book’s analytical/interpretative cuts into the online circulation of museum collections. The pedagogical challenges museums face when collection knowledge is appropriated by groups whose political aims threaten social solidarity and democratic values are discussed. Highlighted are the ways in which collection knowledge is both customised and open-ended when digitisations, narratives and research findings flow between multiple platforms and are transmitted through interfaces including home feeds or lists. We conclude that curatorial agency simultaneously becomes humanist and subjective; machinic and computational; and imbricated in more-than-human ontological formations that insert digitisations and museum knowledge in multi-scalar geographies and temporalities extending from deep geological time into unforeseen futures.

Full textAbstract:
Abstract This chapter discusses two species models, which are diametrically opposed. The first, often called the 'biological species concept', defines species in terms of 'reproductive isolation', convinced that species arise when subsets of a population are split off and remain geographically isolated over evolutionary time. If and when such new species are reunited with their founder population, interbreeding does not occur, or if it does, infertile progeny result. Hence, from the biological species concept, natural selection is a primary agent of change and directly selects for new species. In this sense, species are the direct products of natural selection and they are therefore 'adaptive devices'. When applying this species concept, it has been impossible to separate some sibling species of fruit flies in the genus Bactrocera where distinct morphological species can be similar in molecular analyses of certain DNA sequences, while similar species morphologically are distinct in the same molecular characters. A radically different model, the 'recognition concept of species', relies heavily on a knowledge of species ecology and behaviour, particularly in their natural habitat. The principal points in this concept are given. In contrast to the now-outdated biological species concept that leads one to depend on laboratory-based research to define species, the recognition concept requires workers to undertake extensive field research in the habitat of the taxon under investigation. In translating this approach to research in the insect family Tephritidae, particularly the Dacinae, some 35 years of field surveys have been undertaken throughout the Indian subcontinent, South-east Asia and the South Pacific region. These surveys included trapping using male lure traps and host fruit collections of commercial/edible fruits. The results of this work have included the provision of specimens of almost all known species for morphological descriptions (c.800 species), material for male pheromone chemistry, and data on host fruit relationships and biogeographical studies.

Full textAbstract:
Abstract On August 1,2012 a routine visual inspection showed the presence of unexpected material on the floor of the secondary liner in Tank 241-AY-102 (AY-102). In October 2012, it was determined that waste had leaked into the annulus of AY-102. As a result, an extensive review of Tank AY-102 was conducted quickly triggering increased inspection and monitoring of the tank; however, the precise cause and location of the leak could not be determined. At the same time the Tank AY-102 leak detection pit (LDP) was accumulating water through the drain system external to the secondary tank liner. Liquid collecting in the LDP is suspected to be from water intrusion and collects at a rate such that the LDP must be pumped routinely. Following a routine pumping event, elevated radiation dose rates were noted on the transfer hose and surface contamination readings were found on the transfer pump when it was removed from the Tank AY-102 LDP. These two field readings suggested that tank waste from a secondary liner breach could be leaking into the LDP. Therefore, a plan was initiated to ascertain the integrity of the secondary tank liner including a robotic inspection of the LDP. This paper provides a description of the design components, operational approach, and those results gained from the Tank AY-102 LDP drain piping visual inspection. To perform this inspection, a custom robotic crawler with a deployment device was designed, built, and operated, through subcontract, to inspect the 6 in (152.4mm) leak detection pit drain line. These tasks were accomplished, from initial award of the contract to completion of the inspection, in about two months.

During last years investigations cowering the elaboration of new systems of integrated plant protection became more active by utilization biorational means of plant protection, and electro optic installations. A great attention is accords to elaboration and selection of sour-ces- attractants and new electro optic structures whice must show a high attractively due to a specific irradiation spectrum and, thus, provide a maximum trapping of harmful insects. Application of the light traps is a more perfect method for phenology investigation of many important, in an economic aspect plant pest, and results of insects gathering can by used for elaboration short-term prognoses of insect pests development for rendering more precise the terms for craning out of protection measures. Further the light traps for insect can be used as an independent mean for plant pest combating. Purpose. The existing methods of capturing and collecting harmful insects for the purpose of forecasting and monitoring their development do not ensure the availability of complete data on the species and the density of pest populations. At the same time, many insect species cannot be identified using these methods. Much more effective are the capture methods with the use of ultraviolet radiation sources. The effect of attracting harmful insects with this bait allows to elaborate a variety of trap models, based on the use of light sources with a certain wavelength. Given that more attention is currently being paid to ecological methods of combating pests of agricultural crops, the need has arisen to carry out scientific research activities on the development of new models of multifunctional traps with an ultraviolet light source, with a pronounced effect of attracting harmful noctuid insects. When designing and calculating the basic parameters, the optimal exposure value, the spectral range of the radiation source - of the decoy, as well as the constructive parameters of the device were taken into account. Experimental models of elaborated devices depend, first of all, on their intended purpose and destination. Thus, for signaling the appearance of pests, monitoring their development, determining their density in the given agrocenosis, devices are needed, which ensure the maintenance of the specific appearance of the captured specimens in order to study and classify them by species and groups. It is particularly important to fulfill this condition, to signal the appearance of quarantine pests and to take all measures to limit their spread in time.

The DNA barcoding project provides a very quick and easy way to identify different types of organisms based on their DNA. The main objective of this study is to obtain the sequences of different species of fungi, plants and animals to map the biodiversity of Slovakia. This project also represents a new use for collections stored in natural history museums around the world. This paper shows in particular a laboratory view of the DNA barcoding project, such as the practical application of the methodology for different groups of organisms, the possibilities of using different genes and emphasizes the importance of professional taxonomists. In the museum, we deal with a wide range of samples and we encounter various difficulties. For example, some genera of fungi contain unreadable sections in the middle of the sequence, in insect groups it is a problem with samples killed with ethyl acetate or too old samples, where the DNA is mostly degraded. For the amplification of bird samples, we have found no consistent method for the whole group and we work with several different primer sets and conditions to be able to amplify most of the samples. The identification of various plant species according to their barcodes has also proven quite difficult, as plants are a very specific and fast-evolving group of organisms, and their distinction according to the short barcode regions is nearly impossible. Therefore, we would like to emphasize the necessity of cooperation with specialized taxonomists. Our data are continuously uploaded to the international BOLD database, where there are already more than 500 different species of a wide range of groups of fungi, plants and animals from Slovakia.

Full textAbstract:
The article summarises the world experience of studying the issue of the negative mechanical impact of milking equipment on the health of cows in the process of machine milking. The design, principle of operation and results of experimental studies the special inserts for serial milking cups and teat rubber are presented. Special inserts for liners and milking cups ensure the implementation of physiologically safe principles of machine milking. Compared to a conventional two-chamber teat cup, the teat cup insert ensures pressure equalisation in the teat and interwall spaces during the sucking phase, while the rubber insert reduces the vacuum pressure in the teat space during the compression phase compared to the pressure in the collector chamber. The most common teat liner today has a circular cross-section and is characterised by a sharp transition from the sucking phase to the compression phase, when its cylindrical shell loses stability under the influence of evenly distributed pressure in the intercellular space of the milking cup. In addition, during the compression phase, at the point of closure such a liner has a cross-section in the form of a figure eight, which means that it does not completely disconnect the teat space from the vacuum pressure, which leads to injury to the tip of the teat, especially during dry milking. It was found that when using nipple liners with an insert, the vacuum pressure in the teat spaces of milking cups increases to 17-18 kPa throughout the entire milking period. The pressure in the milk collection chamber of the collector rises to 20-22 kPa. Such indicators largely correspond to the natural suckling of a calf. During production trials over 30 days, the percentage of cows with mastitis decreased by 1.5% and the milk yields increased by 2.2%.

Learning from Nature How to Design Anti-insect Selective Pesticides - Clarification of the Interacting Face between Insecticidal Toxins and their Na-channel Receptors. United States Department of Agriculture, 2010. http://dx.doi.org/10.32747/2010.7697101.bard.
Full textAbstract:
Structural details on the interacting faces of toxins and sodium channels (Navs), and particularly identification of elements that confer specificity for insects, are difficult to approach and require suitable experimental systems. Therefore, natural toxins capable of differential recognition of insect and mammalian Navs are valuable leads for design of selective compounds in insect control. We have characterized several scorpion toxins that vary in preference for insect and mammalian Navs, and identified residues important for their action. However, despite many efforts worldwide, only little is known about the receptor sites of these toxins, and particularly on differences between these sites on insect and mammalian Navs. Another problem arises from the massive overuse of chemical insecticides, which increases resistance buildup among various insect pests. A possible solution to this problem is to combine different insecticidal compounds, especially those that provide synergic effects. Our recent finding that combinations of insecticidal receptor site-3 toxins (sea anemone and scorpion alpha) with scorpion beta toxins or their truncated derivatives are synergic in toxicity to insects is therefore timely and strongly supports this approach. Our ability to produce toxins and various Navs in recombinant forms, enable thorough analysis and structural manipulations of both toxins and receptors. On this basis we propose to (1) restrict by mutagenesis the activity of insecticidal scorpion -toxins and sea anemone toxins to insects, and clarify the molecular basis of their synergic toxicity with antiinsect selective -toxins; (2) identify Nav elements that interact with scorpion alpha and sea anemone toxins and those that determine toxin selectivity to insects; (3) determine toxin-channel pairwise side-chain interactions by thermodynamic mutant cycle analysis using our large collection of mutant -toxins and Nav mutants identified in aim 2; (4) clarify the mode of interaction of truncated -toxins with insect Navs, and elucidate how they enhance the activity of insecticidal site-3 toxins. This research may lead to rational design of novel anti-insect peptidomimetics with minimal impact on human health and the environment, and will establish the grounds for a new strategy in insect pest control, whereby a combination of allosterically interacting compounds increase insecticidal action and reduce risks of resistance buildup.

Rykken, Jessica. Pollinator diversity and floral associations in subarctic sand dunes of Kobuk Valley National Park, Alaska. National Park Service, 2024. http://dx.doi.org/10.36967/2302008.
Full textAbstract:
Active sand dunes in Kobuk Valley National Park are a regionally rare and ecologically distinct landscape feature occurring within the northern boreal biome. The sand dunes harbor a rich diversity of plants, including several rare and disjunct species and the endemic Kobuk locoweed (Oxytropis kobukensis). Pollinators associated with these dune plants have not been studied in Kobuk Valley, despite their essential role in transporting pollen which many plants rely on for successful reproduction. In order to gain a better understanding of pollinator diversity and plant-pollinator associations in this unique ecosystem north of the Arctic Circle, we conducted surveys of bees (Hymenoptera: Anthophila) and syrphid flies (Diptera: Syrphidae) in several places along the Kobuk River and in two active dune areas, the Hunt River Dunes and the Great Kobuk Sand Dunes, in late June-early July of 2017 and 2019. We used active and passive collecting methods to sample pollinators at 21 different sites and along five walking transects, and we documented plant associations for net-collected specimens. In all, we collected 326 bees and 256 syrphid flies, representing 27 and 37 taxa, respectively. The most abundant and widespread species collected among syrphid flies were Lapposyrpus lapponicus and Eristalis obscura. For bees, three soil-nesting solitary species, Andrena barbilabris, Megachile circumcincta, and Osmia tarsata made up 60% of the total bee catch. Dryas integrifolia, a widespread plant on the dunes, hosted the highest number of bee and syrphid fly taxa (13 and 20, respectively). Bumble bees (Bombus) and megachilid bees (Megachile, Osmia) favored several plants in the Fabaceae family, while mining bees (Andrena) were abundant on Salix species (willow). A high diversity of syrphid flies were collected on the composite Packera ogotorukensis, and Salix species. Our collections indicate that the endemic Oxytropis kobukensis was primarily visited by the mason bee, Osmia tarsata (44% of all visitors) and the leafcutter bee, Megachile circumcincta (27%). Bumble bees (genus Bombus) made up another 13% of all visitors to this plant. Our study confirms that the active sand dunes in Kobuk Valley provide an ecologically unique habitat both for plants and their associated insect pollinators. For example, many of the solitary bees living in the dunes rely on deep sands for nesting and thus are limited in their distribution across Arctic and boreal landscapes.

Full textAbstract:
In this project, Intelligent Automation, Incorporated (IAI) and Oak Ridge National Lab (ORNL) propose a novel and integrated approach to inspect the mechanical dents and metal loss in pipelines. It combines the state-of-the-art SH wave Electromagnetic Acoustic Transducer (EMAT) technique, through detailed numerical modeling, data collection instrumentation, and advanced signal processing and pattern classifications, to detect and characterize mechanical defects in the underground pipeline transportation infrastructures. The technique has four components: (1) thorough guided wave modal analysis, (2) recently developed three-dimensional (3-D) Boundary Element Method (BEM) for best operational condition selection and defect feature extraction, (3) ultrasonic Shear Horizontal (SH) waves EMAT sensor design and data collection, and (4) advanced signal processing algorithm like a nonlinear split-spectrum filter, Principal Component Analysis (PCA) and Discriminant Analysis (DA) for signal-to-noise-ratio enhancement, crack signature extraction, and pattern classification. This technology not only can effectively address the problems with the existing methods, i.e., to detect the mechanical dents and metal loss in the pipelines consistently and reliably but also it is able to determine the defect shape and size to a certain extent.

Full textAbstract:
Our project focuses on gene expression and proteomics of the whitefly Bemisia tabaci (Gennadius) species complex in relation to the internal anatomy and localization of expressed genes and virions in the whitefly vector, which poses a major constraint to vegetable and fiber production in Israel and the USA. While many biological parameters are known for begomovirus transmission, nothing is known about vector proteins involved in the specific interactions between begomoviruses and their whitefly vectors. Identifying such proteins is expected to lead to the design of novel control methods that interfere with whitefly-mediated begomovirus transmission. The project objectives were to: 1) Perform gene expression analyses using microarrays to study the response of whiteflies (B, Q and A biotypes) to the acquisition of begomoviruses (Tomato yellow leaf curl (TYLCV) and Squash leaf curl (SLCV). 2) Construct a whitefly proteome from whole whiteflies and dissected organs after begomovirus acquisition. 3) Validate gene expression by q-RTPCR and sub-cellular localization of candidate ESTs identified in microarray and proteomic analyses. 4) Verify functionality of candidate ESTs using an RNAi approach, and to link these datasets to overall functional whitefly anatomical studies. During the first and second years biological experiments with TYLCV and SLCV acquisition and transmission were completed to verify the suitable parameters for sample collection for microarray experiments. The parameters were generally found to be similar to previously published results by our groups and others. Samples from whole whiteflies and midguts of the B, A and Q biotypes that acquired TYLCV and SLCV were collected in both the US and Israel and hybridized to B. tabaci microarray. The data we analyzed, candidate genes that respond to both viruses in the three tested biotypes were identified and their expression that included quantitative real-time PCR and co-localization was verified for HSP70 by the Israeli group. In addition, experiments were undertaken to employ in situ hybridization to localize several candidate genes (in progress) using an oligonucleotide probe to the primary endosymbiont as a positive control. A proteome and corresponding transcriptome to enable more effective protein identification of adult whiteflies was constructed by the US group. Further validation of the transmission route of begomoviruses, mainly SLCV and the involvement of the digestive and salivary systems was investigated (Cicero and Brown). Due to time and budget constraints the RNAi-mediated silencing objective to verify gene function was not accomplished as anticipated. HSP70, a strong candidate protein that showed over-expression after TYLCV and SLCV acquisition and retention by B. tabaci, and co-localization with TYLCV in the midgut, was further studies. Besides this protein, our joint research resulted in the identification of many intriguing candidate genes and proteins that will be followed up by additional experiments during our future research. To identify these proteins it was necessary to increase the number and breadth of whitefly ESTs substantially and so whitefly cDNAs from various libraries made during the project were sequenced (Sanger, 454). As a result, the proteome annotation (ID) was far more successful than in the initial attempt to identify proteins using Uniprot or translated insect ESTs from public databases. The extent of homology shared by insects in different orders was surprisingly low, underscoring the imperative need for genome and transcriptome sequencing of homopteran insects. Having increased the number of EST from the original usable 5500 generated several years ago to >600,000 (this project+NCBI data mining), we have identified about one fifth of the whitefly proteome using these new resources. Also we have created a database that links all identified whitefly proteins to the PAVEdb-ESTs in the database, resulting in a useful dataset to which additional ESTS will be added. We are optimistic about the prospect of linking the proteome ID results to the transcriptome database to enable our own and other labs the opportunity to functionally annotate not only genes and proteins involved in our area of interest (whitefly mediated transmission) but for the plethora of other functionalities that will emerge from mining and functionally annotating other key genes and gene families in whitefly metabolism, development, among others. This joint grant has resulted in the identification of numerous candidate proteins involved in begomovirus transmission by B. tabaci. A next major step will be to capitalize on validated genes/proteins to develop approaches to interfere with the virus transmission.

- Original objectives and revision: The feasibility study performed in the last year was aimed at determining the symbiotic profiles of eight selected Culicoidesspecies in Israel and the USA by: Comparing bacterial communities among geographic populations of primary bluetongue virus (BTV) vectors. Comparing bacterial communities between adults of field-collected, mammal-feeding BTV vectors and non-vectors. Comparing bacterial communities within and between mammal feeders and bird feeders, with special attention to species with unique immature habitats. We made an effort to collect the eight species during the beginning of the project, however, due to the short available collection season, and the significant changes in habitats available for Israeli Culicoides, we initially determined the symbiotic profile of five species: two BTV vectors (C. sonorensis, C. imicola), one mammal feeders with unknown vectoring ability (C. schultzei), one bird feeder (C. crepuscularis), and one unique habitat species (C. cacticola). In addition, upon preliminary symbiont identification we focused our effort on relevant specific symbionts. Background: Biting midges (Culicoides, Diptera: Ceratopogonidae) are vectors of many major viral diseases affecting farm animals, including BT, which is listed among the most damaging by the World Organization for Animal Health (OIE) and has recently emerged in completely unexpected areas (Northern Europe). One of the strategies to reduce the vectorial capacity of insect vectors is by manipulating their specific symbionts either to affect the vector species or to influence performance of the disease agent within it. Despite significant efforts to elucidate the vectorial capacity of certain Culicoidesspecies, and the critical basis of variability in infection, almost no attention has been given to symbiotic interactions between the vector and its bacterial tenants. It is now established that bacterial symbionts have major influences on their host biology, and may interact with disease agents vectored by their hosts. - Major conclusions, solutions, achievements: During the feasibility project we have found two major bacterial symbionts in Israeli and American Culicoides. In Israel we discovered that C. imicola, a known vector of BT, and C. schultzeigp. a suspected vector of BT, carry the symbiotic bacterium Cardinium, a reproductive manipulator symbiont. In C. imicolathe infection rate was close to 50%, and in C. schultzeiit was lower, and restricted to one of two species within Schultzeigroup. In 3 American species (C. sonorensis, C. crepuscularis, C. cacticola) we found the bacterium Burkholderiasp. In all species tested we have also found other bacterial species in diverse quantities and frequencies. - Implications, both scientific and agricultural: Finding specific symbionts in Culicoidesvector species is the first step in developing symbiont based control (SBC) strategies. Both identified symbionts are known from other insects, and Cardiniumis also known as a reproductive manipulator that can cause cytoplasmic incompatibility, an important phenomenon that can be used for spreading desired traits in infected populations. The role of the symbionts in Culicoideshost can be target for manipulation to reduce the vectorial capacity of the host by either changing its fitness so that it is unable to serve as a vector, or by directly changing the symbiont in a way that will affect the performance of the disease agent in its vector. Since Burkholderiaperhaps can be cultured independently of the host, it is a promising candidate for the later option. Thus, we have now opened the door for studying the specific interactions between symbionts and vector species.

Full textAbstract:
Despite the rapid increase in reliance on bumble bees for food production and security, there are many critical knowledge gaps in our understanding of bumble bee biology that limit their colony production, commercial management, and pollination services. Our project focuses on the social, endocrine, and molecular processes regulating body size in the two bumble bee species most important to agriculture: Bombus terrestris in Israel, and B. impatiens in the USA. Variation in body size underline both caste (queen/worker) differentiation and division of labor among workers (foragers are typically larger than nest bees), two hallmarks of insect sociality which are also crucial for the commercial rearing and crop pollination services of bumble bees. Our project has generated several fundamental new insights into the biology of bumble bees, which can be integrated into science-based management strategies for commercial pollination. Using transcriptomic and behavioral approaches we show that in spite of high flexibility, task performance (brood care or foraging) in bumble bee colonies is associated with physiological variation and differential brain gene expression and RNA editing patterns. We further showed that interactions between the brood, the queen, and the workers determine the developmental program of the larva. We identified two important periods. The first is a critical period during the first few days after hatching. Larvae fed by queens during this period develop over less days, are not likely to develop into gynes, and commonly reach a smaller ultimate body size compared to workers reared mostly or solely by workers. The facial exocrine (mandibular and hypopharangeal) glands are involved in this queen effect on larva development. The second period is important for determining the ultimate body size which is positively regulated by the number of tending workers. The presence of the queen during this stage has little, if at all, influence. We further show that stressors such as agrochemicals that interfere with foraging or brood care specific processes can compromise bumble bee colony development and their pollination performance. We also developed new technology (an RFID system) for automated collection of foraging trip data, for future deployment in agroecosystems. In spite of many similarities, our findings suggest important differences between the Eurasian model species (B. terrestris) and the North American model species (B. impatiens) that impact how management strategies translate across the two species. For example, there is a similar influence of the queen on offspring body size in both species, but this effect does not appear to be mediated by development time in B. impatiens as it is in B. terrestris. Taken together, our collaboration highlights the power of comparative work, to show that considerable differences that exist between these two key pollinator species, and in the organization of young bumble bee nests (wherein queens provide the majority of care and then transition away from brood care) relative to later stages of nest development.
