    www.nature.com/scientificreports OPEN Mosquito species identifcation using convolutional neural networks with a multitiered ensemble model for novel species detection Adam Goodwin1,2*, Sanket Padmanabhan1,2, Sanchit Hira2,3, Margaret Glancey1,2, Monet Slinowsky2, Rakhil Immidisetti2,3, Laura Scavo2, Jewell Brey2, Bala Murali Manoghar Sai Sudhakar1, Tristan Ford1,2, Collyn Heier2, Yvonne‑Marie Linton4,5,6, David B. Pecor4,5,6, Laura Caicedo‑Quiroga4,5,6 & Soumyadipta Acharya2* With over 3500 mosquito species described, accurate species identifcation of the few implicated in disease transmission is critical to mosquito borne disease mitigation. Yet this task is hindered by limited global taxonomic expertise and specimen damage consistent across common capture methods. Convolutional neural networks (CNNs) are promising with limited sets of species, but image database requirements restrict practical implementation. Using an image database of 2696 specimens from 67 mosquito species, we address the practical open‑set problem with a detection algorithm for novel species. Closed‑set classifcation of 16 known species achieved 97.04 ± 0.87% accuracy independently, and 89.07 ± 5.58% when cascaded with novelty detection. Closed‑set classifcation of 39 species produces a macro F1‑score of 86.07 ± 1.81%. This demonstrates an accurate, scalable, and practical computer vision solution to identify wild‑caught mosquitoes for implementation in biosurveillance and targeted vector control programs, without the need for extensive image database development for each new target region. Mosquitoes are one of the deadliest animals in the world, infecting between 250–500 million people every year with a wide range of fatal or debilitating diseases, including malaria, dengue, chikungunya, Zika and West Nile Virus1.

Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic areas in which it has not yet been introduced. To identify unknown vectors of Zika, we developed a data-driven model linking vector species and the Zika virus via vector-virus trait combinations that confer a propensity toward associations in an ecological network connecting flaviviruses and their mosquito vectors. Our model predicts that thirty-five species may be able to transmit the virus, seven of which are found in the continental United States, including Culex quinquefasciatus and Cx. pipiens. We suggest that empirical studies prioritize these species to confirm predictions of vector competence, enabling the correct identification of populations at risk for transmission within the United States. *For correspondence: mvevans@ DOI: 10.7554/eLife.22053.001 uga.edu Competing interests: The authors declare that no competing interests exist.

SuCPV produces small (typically 0.25 m), polyhedral shaped inclusion bodies (polyhedra), in which the virus particles become multiply embedded. SuCPV is the third cypovirus isolated from Diptera, but the Wrst from Simuliidae that has been characterized using molecular analyses. SuCPV has a genome composed of 10 segments of dsRNA, with an electrophoretic migration pattern that is diVerent from those of recent UsCPV-17 and CrCPV-17 isolates from the mosquitoes Uranotaenia sapphirina and Culex restuans, respectively. The SuCPV electropherotype appears to show signiWcant diVerences from those of the previously characterized lepidopteran cypoviruses. Sequence analysis of SuCPV segment 10 shows that it is unrelated to either of the two CPV isolates from Diptera or to the CPV species for which Seg-10 has been previously characterized from Lepidoptera. A comparison of the terminal regions of SuCPV genome segments to those of CPV-1, 2, 4, 5 14, 15, 16, 17, 18, and 19 also revealed only low levels of conservation.

Student Corner 2 Many of our country’s most important inland biological field stations, as they were once Research Spotlight 3 called, came into being quite intentionally during the middle of the last century. Most News & Notes 4-5 were designed to serve as regional platforms for college courses, collecting forays, or A Look Back at the 2018 Season 6-7 land management efforts. During the 1960s and 70s some took on themed research missions – hydrology, ecosystem dynamics, forest ecology, agriculture, lake processes, prairie dynamics, population biology, animal behavior, etc. Field research is now a globe-trotting industry with graduate students choosing systems and questions independent of local biology, or field stations. Today’s field stations must play host to biologists from around the world, and are learning how to support and retain international scientists who face special challenges, including time zones, travel costs and time, language, culture, academic schedules, funding disparities, rules and regulations in two countries, and immigration and visa complexities. To attract international users, field stations must remove barriers, e.g., program schedules designed to align only with US calendars, or excessive permitting requirements. If stations can do this, they and their host institutions will reap the benefits of bringing together scientists with different training, perspectives, conceptual tools, and ways of thinking. Dr. Adriana Herrera Montes is primarily interested in how human disturbance, specifically human environmental engineering, impacts biodiversity and vertebrate ecosystem services.

  • Mosquitopia: the Place of Pests in a Healthy World / Edited by Marcus Hall and Dan Tamir
    MOSQUITOPIA This edited volume brings together natural scientists, social scientists and humanists to assess if (or how) we may begin to coexist harmoniously with the mosquito. The mosquito is humanity’s deadliest animal, killing over a million people each year by transmitting malaria, yellow fever, Zika and several other diseases. Yet of the 3,500 species of mosquito on Earth, only a few dozen of them are really dangerous—so that the question arises as to whether humans and their mosquito foe can learn to live peacefully with one another. Chapters assess polarizing arguments for conserving and preserving mosquitoes, as well as for controlling and killing them, elaborating on possible consequences of both strategies. This book provides informed answers to the dual question: could we eliminate mosquitoes, and should we? Offering insights spanning the technical to the philosophical, this is the “go to” book for exploring humanity’s many relationships with the mosquito—which becomes a journey to finding better ways to inhabit the natural world. Mosquitopia will be of interest to anyone wanting to explore dependencies between human health and natural systems, while offering novel perspectives to health planners, medical experts, environmentalists and animal rights advocates. Marcus Hall is an environmental historian and professor at the University of Zurich. In exploring changing human relationships with the natural world, Hall has turned to such subjects as restoring, rewilding, invasive species, warfare, earth art, chronobi- ology, malaria, and parasites. His books include Earth Repair, Restoration and History, Crossing Mountains, and (with Marco Armiero) Nature and History in Modern Italy. Dan Tamïr is environmental historian and research associate at the University of Zurich.

    DIRECT AND INDIRECT EFFECTS OF NATIVE AND INVASIVE PLANTS ON MOSQUITO ECOLOGY BY ALLISON MAE GARDNER DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2016 Urbana, Illinois Doctoral Committee: Assistant Professor Brian F. Allan, Chair, Co-Director of Research Dr. Ephantus J. Muturi, Co-Director of Research Professor May R. Berenbaum Professor Lawrence M. Hanks Assistant Professor Allison K. Hansen Abstract Container-breeding mosquitoes (Diptera: Culicidae), including the vectors of human and wildlife pathogens, interact with terrestrial plants throughout their life cycles. Inputs of leaf detritus into the aquatic habitat provide an energy base for developing larvae, and plants mediate the distribution of adult mosquitoes by influencing microclimate conditions, supplying sugar-feeding sources, and altering communities of wildlife blood-meal hosts. This dissertation examines direct and indirect effects of understory shrubs, including species both native and invasive to North America, on the ecology of Culex pipiens, an important vector of West Nile virus in the northeastern and midwestern United States. Laboratory and field bioassays demonstrated that leaf detritus from different plant species in the aquatic environment alter two key components of mosquito production (i.e., oviposition site selection and adult emergence) via the abundance and composition of bacterial flora that form on different leaf species as they decompose. In particular, an invasive plant (Lonicera maackii, Amur honeysuckle) yielded high oviposition and adult emergence rates, while in contrast, a native plant (Rubus allegheniensis, common blackberry) was identified to function as an ecological trap for Cx.
