Identification Keys to the Anopheles Mosquitoes of South America
Sallum et al. Parasites Vectors (2020) 13:583 https://doi.org/10.1186/s13071-020-04298-6 Parasites & Vectors RESEARCH Open Access Identifcation keys to the Anopheles mosquitoes of South America (Diptera: Culicidae). I. Introduction Maria Anice Mureb Sallum1*, Ranulfo González Obando2, Nancy Carrejo2 and Richard C. Wilkerson3,4,5 Abstract Background: The worldwide genus Anopheles Meigen, 1918 is the only genus containing species evolved as vectors of human and simian malaria. Morbidity and mortality caused by Plasmodium Marchiafava & Celli, 1885 is tremendous, which has made these parasites and their vectors the objects of intense research aimed at mosquito identifcation, malaria control and elimination. DNA tools make the identifcation of Anopheles species both easier and more difcult. Easier in that putative species can nearly always be separated based on DNA data; more difcult in that attaching a scientifc name to a species is often problematic because morphological characters are often difcult to interpret or even see; and DNA technology might not be available and afordable. Added to this are the many species that are either not yet recognized or are similar to, or identical with, named species. The frst step in solving Anopheles identi- fcation problem is to attach a morphology-based formal or informal name to a specimen. These names are hypoth- eses to be tested with further morphological observations and/or DNA evidence. The overarching objective is to be able to communicate about a given species under study. In South America, morphological identifcation which is the frst step in the above process is often difcult because of lack of taxonomic expertise and/or inadequate identifca- tion keys, written for local fauna, containing the most consequential species, or obviously, do not include species described subsequent to key publication. -
Annual Report 2017-2
Department of Medical Biochemistry and Microbiology IMBIM ANNUAL REPORT 2017 DEPARTMENT OF MEDICAL BIOCHEMISTRY AND MICROBIOLOGY ANNUAL REPORT 2017 Theses published at IMBIM in 2017 Edited by Veronica Hammar ISBN no 978-91-983979-3-2 PREFACE A university department is in its character a dynamic place. PhD students come and complete their education within 4-5 years. Postdoctoral fellows join for a relatively short time, maybe to change gears and learn a new field or just acquire more experience to become competitive for a tenure. Many researchers are recruited by groups where more hands and skills are needed. IMBIM is not an exception. But 2017 was extraordinary since the former Ludwig Institute for Cancer Research merged with IMBIM in August. This was of course a much welcome addition complementing and strengthening our research in cell and molecular cancer biology. As of the end of 2017 IMBIM had 165 employees and 105 registered with IMBIM as working place or employed elsewhere, but doing research at IMBIM. Here I would take the opportunity to welcome and congratulate Örjan Carlborg who 2017 was promoted to professor, Evi Heldin who was appointed guest professor and Kristofer Rubin who was also appointed guest professor and Director of BMC. During the month of May, the Quality and Renewal (KoF) evaluation panel visited IMBIM for two days of intensive discussions. Their assessment was also based on a self-evaluation most diligently assembled by IMBIM’s former Head of department, Göran Akusjärvi. It was as great pleasure to read the comment from the evaluation panel: “The self-evaluation report is an excellent summary of the current state of the department with ample and thoughtful self- reflection and self-criticism”. -

Impact of human activities upon dipterans communities in tropical savannas. Glossary Bibliography Biographical Sketch UNESCO – EOLSS Summary Dipterous are a very much diversified group of insects that occurs in almost all tropical habitats and alsoSAMPLE other terrestrial biomes. Some CHAPTERS diptera are important from the economic and public health point of view. Mosquitoes and sandflies are, respectively, vectors of malaria and leishmaniasis in the major part of tropical countries. Housefly and blowflies are mechanical vectors of many pathogens, and the larvae of the latter may parasitize humans and other animals, as well. Nevertheless, the majority of diptera are inoffensive to humans and several of them are benefic, having important roles in nature such as pollinators of plants, recyclers of decaying organic matter and natural enemies of other insects, including pests. 1.

Application of Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry to Identify Species of Neotropical Anopheles Vector
Loaiza et al. Malar J (2019) 18:95 https://doi.org/10.1186/s12936-019-2723-0 Malaria Journal RESEARCH Open Access Application of matrix-assisted laser desorption/ionization mass spectrometry to identify species of Neotropical Anopheles vectors of malaria Jose R. Loaiza1,2,3 , Alejandro Almanza1, Juan C. Rojas1, Luis Mejía1,2, Norma D. Cervantes4, Javier E. Sanchez‑Galan1,5, Fernando Merchán6, Arnaud Grillet6,7, Matthew J. Miller8, Luis F. De León1,9 and Rolando A. Gittens1,10* Abstract Background: Malaria control in Panama is problematic due to the high diversity of morphologically similar Anopheles mosquito species, which makes identifcation of vectors of human Plasmodium challenging. Strategies by Panama‑ nian health authorities to bring malaria under control targeting Anopheles vectors could be inefective if they tackle a misidentifed species. Methods: A rapid mass spectrometry identifcation procedure was developed to accurately and timely sort out feld‑collected Neotropical Anopheles mosquitoes into vector and non‑vector species. Matrix‑assisted laser desorp‑ tion/ionization (MALDI) mass spectra of highly‑abundant proteins were generated from laboratory‑reared mosquitoes using diferent extraction protocols, body parts, and sexes to minimize the amount of material from specimen vouch‑ ers needed and optimize the protocol for taxonomic identifcation. Subsequently, the mass spectra of feld‑collected Neotropical Anopheles mosquito species were classifed using a combination of custom‑made unsupervised (i.e., Principal component analysis—PCA) and supervised (i.e., Linear discriminant analysis—LDA) classifcation algorithms. Results: Regardless of the protocol used or the mosquito species and sex, the legs contained the least intra‑specifc variability with enough well‑preserved proteins to diferentiate among distinct biological species, consistent with pre‑ vious literature. -

The ongoing battle against malaria has been hampered by the emergence of drug and insecticide resistance amongst parasites and vectors, re- spectively. The Sterile Insect Technique (SIT) and genetically modified mosquitoes (GM) are new proposed vector control approaches. Successful implementation of these ap- proaches requires a better understanding of male mating biology of target mosquito species. -

HARBACH & THERESA M. HOWARD Department of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, U.K. E-mail: [email protected]; [email protected] Abstract Genus Chagasia Cruz of subfamily Anophelinae (Diptera: Culicidae) is comprised of five species in the Neotropical Region: Ch. ablusa Harbach, n. sp., Ch. bathana (Dyar), Ch. bonneae Root, Ch. fajardi (Lutz) and Ch. rozeboomi Causey, Deane & Deane. The genus is described in detail and diagnoses, keys and illustrations are provided for the identification of the adult, pupal and larval stages of each species. The larval and pupal stages of a Chagasia species (Ch. bonneae) are fully illustrated for the first time. A neotype specimen is designated for Ch. fajardi to fix its identity and distinguish it from Ch. ablusa. The species treatments also include a synonymy (where applicable), a discussion, information on distribution, a synopsis of material examined and a summary of previous literature. The work is considered to be a review rather than a revision of the genus because too few link-reared specimens were available for detailed comparative study of all life stages, and it was not possible to determine the total range of morphological variation and the actual distributions of the species. Key words: ablusa new species, bathana, bonneae, fajardi, mosquito, rozeboomi, taxonomy Introduction Mosquitoes, family Culicidae, comprise two principal phyletic lineages that are recognised as subfamilies, the Anophelinae and Culicinae (Harbach & Kitching, 1998, Mitchell et al., 2002). -

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1691. 54 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0381-9. Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. A problem with these measures is the development of resistance, both in the parasites against the drugs and the mosquitoes against the insecticides. Therefore, additional areas of malaria control must be explored. One such area involves the bacteria associated with the vector mosquitoes. Bacteria have been shown to affect mosquitoes at all life stages, e.g. by affecting choice of oviposition site by female mosquitoes, development of larvae and susceptibility to parasite infection in adults. -
Flight Tone Characterisation of the South American Malaria Vector Anopheles Darlingi (Diptera: Culicidae)
ORIGINAL ARTICLE Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 116: e200497, 2021 1|6 Flight tone characterisation of the South American malaria vector Anopheles darlingi (Diptera: Culicidae) Jose Pablo Montoya1, Hoover Pantoja-Sánchez2,3, Sebastian Gomez1,2, Frank William Avila4, Catalina Alfonso-Parra1,4/+ 1Universidad CES, Instituto Colombiano de Medicina Tropical, Sabaneta, Antioquia, Colombia 2Universidad de Antioquia, Departamento de Ingeniería Electrónica, Medellín, Antioquia, Colombia 3Universidad de Antioquia, Programa de Estudio y Control de Enfermedades Tropicales, Medellín, Antioquia, Colombia 4Universidad de Antioquia, Max Planck Tandem Group in Mosquito Reproductive Biology, Medellín, Antioquia, Colombia BACKGROUND Flight tones play important roles in mosquito reproduction. Several mosquito species utilise flight tones for mate localisation and attraction. Typically, the female wingbeat frequency (WBF) is lower than males, and stereotypic acoustic behaviors are instrumental for successful copulation. Mosquito WBFs are usually an important species characteristic, with female flight tones used as male attractants in surveillance traps for species identification. Anopheles darlingi is an important Latin American malaria vector, but we know little about its mating behaviors. OBJECTIVES We characterised An. darlingi WBFs and examined male acoustic responses to immobilised females. METHODS Tethered and free flying male and female An. darlingi were recorded individually to determine their WBF distributions. Male-female acoustic interactions were analysed using tethered females and free flying males. FINDINGS Contrary to most mosquito species, An. darlingi females are smaller than males. However, the male’s WBF is ~1.5 times higher than the females, a common ratio in species with larger females. When in proximity to a female, males displayed rapid frequency modulations that decreased upon genitalia engagement. -
Ecology of Anopheles Darlingi Root with Respect to Vector Importance: a Review Hélène Hiwat1,2* and Gustavo Bretas3
Hiwat and Bretas Parasites & Vectors 2011, 4:177 http://www.parasitesandvectors.com/content/4/1/177 REVIEW Open Access Ecology of Anopheles darlingi Root with respect to vector importance: a review Hélène Hiwat1,2* and Gustavo Bretas3 Abstract Anopheles darlingi is one of the most important malaria vectors in the Americas. In this era of new tools and strategies for malaria and vector control it is essential to have knowledge on the ecology and behavior of vectors in order to evaluate appropriateness and impact of control measures. This paper aims to provide information on the importance, ecology and behavior of An. darlingi. It reviews publications that addressed ecological and behavioral aspects that are important to understand the role and importance of An. darlingi in the transmission of malaria throughout its area of distribution. The results show that Anopheles darlingi is especially important for malaria transmission in the Amazon region. Although numerous studies exist, many aspects determining the vectorial capacity of An. darlingi, i.e. its relation to seasons and environmental conditions, its gonotrophic cycle and longevity, and its feeding behavior and biting preferences, are still unknown. The vector shows a high degree of variability in behavioral traits. This makes it difficult to predict the impact of ongoing changes in the environment on the mosquito populations. Recent studies indicate a good ability of An. darlingi to adapt to environments modified by human development. This allows the vector to establish populations in areas where it previously did not exist or had been controlled to date. The behavioral variability of the vector, its adaptability, and our limited knowledge of these impede the establishment of effective control strategies.
