Mosquito Species Identification Using Convolutional Neural Networks With
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. -

Irish et al. Parasites & Vectors (2016) 9:559 DOI 10.1186/s13071-016-1848-z RESEARCH Open Access A review of the mosquito species (Diptera: Culicidae) of Bangladesh Seth R. Irish1*, Hasan Mohammad Al-Amin2, Mohammad Shafiul Alam2 and Ralph E. Harbach3 Abstract Background: Diseases caused by mosquito-borne pathogens remain an important source of morbidity and mortality in Bangladesh. To better control the vectors that transmit the agents of disease, and hence the diseases they cause, and to appreciate the diversity of the family Culicidae, it is important to have an up-to-date list of the species present in the country. Original records were collected from a literature review to compile a list of the species recorded in Bangladesh. Results: Records for 123 species were collected, although some species had only a single record. This is an increase of ten species over the most recent complete list, compiled nearly 30 years ago. Collection records of three additional species are included here: Anopheles pseudowillmori, Armigeres malayi and Mimomyia luzonensis. Conclusions: While this work constitutes the most complete list of mosquito species collected in Bangladesh, further work is needed to refine this list and understand the distributions of those species within the country. Improved morphological and molecular methods of identification will allow the refinement of this list in years to come.

A Classification System for Mosquito Life Cycles: Life Cycle Types for Mosquitoes of the Northeastern United States
June, 2004 Journal of Vector Ecology 1 Distinguished Achievement Award Presentation at the 2003 Society for Vector Ecology Meeting A classification system for mosquito life cycles: life cycle types for mosquitoes of the northeastern United States Wayne J. Crans Mosquito Research and Control, Department of Entomology, Rutgers University, 180 Jones Avenue, New Brunswick, NJ 08901, U.S.A. Received 8 January 2004; Accepted 16 January 2004 ABSTRACT: A system for the classification of mosquito life cycle types is presented for mosquito species found in the northeastern United States. Primary subdivisions include Univoltine Aedine, Multivoltine Aedine, Multivoltine Culex/Anopheles, and Unique Life Cycle Types. A montotypic subdivision groups life cycle types restricted to single species. The classification system recognizes 11 shared life cycle types and three that are limited to single species. Criteria for assignments include: 1) where the eggs are laid, 2) typical larval habitat, 3) number of generations per year, and 4) stage of the life cycle that overwinters. The 14 types in the northeast have been named for common model species. A list of species for each life cycle type is provided to serve as a teaching aid for students of mosquito biology.

JEBANESAN, M.Sc., M.Ed., PGDHE., Ph.D., Professor & Principal Investigator, Department of Zoology, Annamalai University, Annamalainagar - 608 002. Tamil Nadu, INDIA. INTRODUCTION Mosquitoes are dipteran insects and blood sucking flies pest of man. They have always given tough time to men as important carriers of various diseases. People fight globally against mosquitoes and mosquito borne diseases. Mosquito vectors transmit parasites responsible for diseases such as Malaria, Dengue Fever (DF), Chikungunya (CG), Filariasis, Yellow Fever and various forms of Encephalitis such as Japanese Encephalitis (JE), Eastern Equine Encephalitis, St. Louis Encephalitis, Western Equine Encephalitis, Venezuelan Equine Encephalitis, etc. In January 2016, the World Health Organization (WHO) said that the Zika virus was likely to spread throughout the majority of the America by the end of the year. Mosquitoes breed in permanent, semi-permanent and temporary water bodies viz., running water, human dwelling, cattle shed, cess pits, tree holes, rock holes, cess pools, containers and discarded materials. The larval stage is aquatic and mosquito larval habitats are varied, which starts from tree holes to ponds and lakes. Tree holes provide a unique specialized type of ecological habitat which is different from the usual breeding places of the other species of mosquitoes. Tree holes habitats (phytotelmata) are small natural containers formed by living or dead plant parts when rainwater is collected in bark depressions. -

Contributions to the Mosquito Fauna of Southeast Asia II
ILLUSTRATED KEYS TO THE GENERA OF MOSQUITOES1 BY Peter F. Mattingly 2 INTRODUCTION The suprageneric and generic classification adopted here follow closely the Synoptic Catalog of the Mosquitoes of the World (Stone et al. , 1959) and the various supplements (Stone, 1961, 1963, 1967,’ 1970). Changes in generic no- menclature arising from the publication of the Catalog include the substitution of Mansonia for Taeniorhynchus and Culiseta for Theobaldiu, bringing New and Old World practice into line, the substitution of Toxorhynchites for Megarhinus and MaZaya for Harpagomyia, the suppression of the diaeresis in Aties, A&deomyia (formerly Atiomyia) and Paraties (Christophers, 1960b) and the inclusion of the last named as a subgenus of Aedes (Mattingly, 1958). The only new generic name to appear since the publication of the Catalog is Galindomyiu (Stone & Barreto, 1969). Mimomyia, previously treated as a subgenus of Ficalbia, is here treated, in combination with subgenera Etorleptiomyia and Rauenulites, as a separate genus. Ronderos & Bachmann (1963a) proposed to treat Mansonia and Coquillettidia as separate genera and they have been fol- lowed by Stone (1967, 1970) and others. I cannot accept this and they are here retained in the single genus Mansonia. It will be seen that the treatment adopted here, as always with mosquitoes since the early days, is conservative. Inevitably, therefore, dif- fictiIties arise in connection with occasional aberrant species. In order to avoid split, or unduly prolix, couplets I have preferred, in nearly every case, to deal with these in the Notes to the Keys. The latter are consequently to be regarded as very much a part of the keys themselves and should be constantly borne in mind. -
The Genus Or Thopodomyla Theobald in Southeast Asia ’
THE GENUS OR THOPODOMYLA THEOBALD IN SOUTHEAST ASIA ’ BY Thomas J. Zavortink2 INTRODUCTION This paper treats the 7 species of Orthopodomyia which occur in the Southeast Asian area. Although it has been 1 argely extracted from a m ore comprehensive study of the entire genus (Zavortink 1968), several significant changes and additions have been made. These include the following: keys to species have been rewritten and made more artificial; descriptions of the spe- cies have been shortened and restricted to characters which are diagnostic or at least characteristic of one or more species; discussions and group descrip- tions have been modified to pertain only to species found within the Southeast Asian region; descriptions have been corrected, where necessary, to accomo- date variations observed during examination of additional specimens; sections on distribution and biology now include more extensive data for the Thailand collections; and a recently described species has been included. The terminology of the present paper generally conforms to that of Belkin 1962 and the format to that of Bram (1967), Delfinado (1967, 1968), and Knight I 19681 . An asterisk following the abbreviations used (d = male, 9 = fe- male, P = pupa, and L = larva) indicates that all or some portion of that sex or stage is illustrated. Abbreviations used for the references to the literature conform to the World List of Scientific Periodicals, 3rd ed., Academic Press, 1952. Types of the included species which are in the British Museum (Natural History) and the United States National Museum have been studied by me. In addition to material accumulated by the Southeast Asia Mosquito Project, specimens from the following institutions were examined: Bernice P. -
