  • 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.

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).

It is necessary to update the data from time to time. The effort of updating the mosquito fauna was started from South Sumatra Province. Amount of 2,784 mosquito specimens were examined. The result showed there are 62 species of mosquitoes from South Sumatra Province and they belong to 10 genera. One species of culicid mosquito were recorded for the first time from Indonesia, namely Aedes (Downsiomyia) pexus and six other species were first recorded on Sumatra Island. These species are now included in the Sumatran Culicidae checklist. Key words: Indonesia, mosquito fauna, new species record, South Sumatra INTRODUCTION Many species of Culicidae family, or known as mosquitoes, have been recognised as vectors of medically important pathogens and parasites such as viruses, protozoans, and nematodes that are causing diseases in human. Culicidae family includes two sub-families, 44 genera, 145 subgenera and 3,490 species worldwide (Harbach & Howard 2007).

  • Culicidae Evolutionary History Focusing on the Culicinae Subfamily
    www.nature.com/scientificreports OPEN Culicidae evolutionary history focusing on the Culicinae subfamily based on mitochondrial phylogenomics Alexandre Freitas da Silva1, Laís Ceschini Machado1, Marcia Bicudo de Paula2, Carla Júlia da Silva Pessoa Vieira3, Roberta Vieira de Morais Bronzoni3, Maria Alice Varjal de Melo Santos1 & Gabriel Luz Wallau1* Mosquitoes are insects of medical importance due their role as vectors of diferent pathogens to humans. There is a lack of information about the evolutionary history and phylogenetic positioning of the majority of mosquito species. Here we characterized the mitogenomes of mosquito species through low-coverage whole genome sequencing and data mining. A total of 37 draft mitogenomes of diferent species were assembled from which 16 are newly-sequenced species. We datamined additional 49 mosquito mitogenomes, and together with our 37 mitogenomes, we reconstructed the evolutionary history of 86 species including representatives from 15 genera and 7 tribes. Our results showed that most of the species clustered in clades with other members of their own genus with exception of Aedes genus which was paraphyletic. We confrmed the monophyletic status of the Mansoniini tribe including both Coquillettidia and Mansonia genus. The Aedeomyiini and Uranotaeniini were consistently recovered as basal to other tribes in the subfamily Culicinae, although the exact relationships among these tribes difered between analyses. These results demonstrate that low- coverage sequencing is efective to recover mitogenomes, establish phylogenetic knowledge and hence generate basic fundamental information that will help in the understanding of the role of these species as pathogen vectors. Mosquitoes compose a large group of insects from the Culicidae family.

  • The Biology of Blood-Sucking in Insects, SECOND EDITION
    This page intentionally left blank The Biology of Blood-Sucking in Insects Second Edition Blood-sucking insects transmit many of the most debilitating dis- eases in humans, including malaria, sleeping sickness, filaria- sis, leishmaniasis, dengue, typhus and plague. In addition, these insects cause major economic losses in agriculture both by direct damage to livestock and as a result of the veterinary diseases, such as the various trypanosomiases, that they transmit. The second edition of The Biology of Blood-Sucking in Insects is a unique, topic- led commentary on the biological themes that are common in the lives of blood-sucking insects. To do this effectively it concentrates on those aspects of the biology of these fascinating insects that have been clearly modified in some way to suit the blood-sucking habit. The book opens with a brief outline of the medical, social and economic impact of blood-sucking insects. Further chapters cover the evolution of the blood-sucking habit, feeding preferences, host location, the ingestion of blood and the various physiological adap- tations for dealing with the blood meal. Discussions on host–insect interactions and the transmission of parasites by blood-sucking insects are followed by the final chapter, which is designed as a use- ful quick-reference section covering the different groups of insects referred to in the text. For this second edition, The Biology of Blood-Sucking in Insects has been fully updated since the first edition was published in 1991. It is written in a clear, concise fashion and is well illustrated through- out with a variety of specially prepared line illustrations and pho- tographs.

They are deadly insects transmitting diseases such as malaria, elephantiasis and several arboviruses. The adaptability of mosquitoes is a problem and this is tantamount to greaterAim: spread of diseases. Malaria is the most widespread mosquito borne disease in Nigeria where it is holoendemic. The source of malaria problem is the diverse breeding sites of mosquitoes. This work investigates preferred mosquito breeding water sites,Methods: physicochemical factors and colour cues influencing oviposition and development of mosquitoes. Investigations were carried out on the preferred oviposition and breeding water sites of mosquitoes in the wild during the rainy season. 100 CL of water were collected from five water samples each of packaged water, polluted water, pond water, tap water and rain water. The water samples were transferred to five green and five transparent containers (200CL) each and left opened in a well ventilated laboratory overnight for fourResults: weeks. Daily temperature and weekly Hydrogen ion concentration (ph) of the water in each container were taken.
