Phenotypic Diversity in Culex Vishnui Theobald (Culicidae: Diptera)
International Journal of Mosquito Research 2017; 4(4): 95-100 ISSN: 2348-5906 CODEN: IJMRK2 IJMR 2017; 4(4): 95-100 Phenotypic diversity in Culex vishnui Theobald © 2017 IJMR Received: 03-05-2017 (Culicidae: Diptera) Accepted: 04-06-2017 Monika Airi Monika Airi Assistant Professor, Department of Zoology, Sri Guru Granth Abstract Sahib World University, Samples of Culex vishnui Theobald randomly collected from different water bodies in Chandigarh and Fatehgarh Sahib, Punjab, India surrounding parts of Punjab and Haryana states reveal significant morphological differences which may be minor or quite apparent. These differences relate to the distribution and colouration of scales on different parts of body including head, legs and abdomen. The scales present on proboscis and maxillary palp are arranged in a few bands or some of them are scattered on general surface. Their colour varies from pale to dark brown. The shape of such bands on abdominal terga also varies from transverse to triangular bands. The male genitalia is also highly variable presenting difference in number of finger like processes on phallosome along with the length of mesal spine and sternal spine. Possible causes for the appearance of alternate phenotypes have been discussed. Keywords: Mosquito, Culex vishnui, taxonomy, Intraspecific variations. 1. Introduction Culex vishui Theobald 1901 belongs to subgenus Culex of Genus Culex. In India this genus is represented by seven subgenera i.e. Barraudius, Culex, Culiciomyia, Eumelanomyia, Lophoceraomyia, Oculeomyia and Maillotia [1]. Among these, the members of subgenus Culex are most dominant and are the vectors of various diseases like filariasis, elephantiasis and Japanese encephalitis [2, 3]. -

RESEARCH ARTICLE Data-driven identification of potential Zika virus vectors Michelle V Evans1,2*, Tad A Dallas1,3, Barbara A Han4, Courtney C Murdock1,2,5,6,7,8, John M Drake1,2,8 1Odum School of Ecology, University of Georgia, Athens, United States; 2Center for the Ecology of Infectious Diseases, University of Georgia, Athens, United States; 3Department of Environmental Science and Policy, University of California-Davis, Davis, United States; 4Cary Institute of Ecosystem Studies, Millbrook, United States; 5Department of Infectious Disease, University of Georgia, Athens, United States; 6Center for Tropical Emerging Global Diseases, University of Georgia, Athens, United States; 7Center for Vaccines and Immunology, University of Georgia, Athens, United States; 8River Basin Center, University of Georgia, Athens, United States Abstract Zika is an emerging virus whose rapid spread is of great public health concern. 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. -
Establishment of a Multiplex RT-PCR for the Sensitive and Differential Detection of Japanese Encephalitis Virus Genotype 1 and 3
Journal of Bacteriology and Virology 2016. Vol. 46, No. 4 p.231 – 238 http://dx.doi.org/10.4167/jbv.2016.46.4.231 Original Article Establishment of a Multiplex RT-PCR for the Sensitive and Differential Detection of Japanese Encephalitis Virus Genotype 1 and 3 * Dong-Kun Yang , Ha-Hyun Kim, Hyun-Ye Jo, Sung-Suk Choi and In-Soo Cho Viral Disease Division, Animal and Plant Quarantine Agency, Gyeongsangbuk-do, Korea Japanese encephalitis (JE) is a zoonosis that affects the nervous system of humans and other animals. The genotype of JE virus (JEV) has shifted recently from genotype 3 (G3) to genotype 1 (G1) in Asia, including Korea. Thus, a rapid differential assay is required to make an accurate diagnosis of JEV genotype. In this study, we designed common and differential primer sets for JEV G1 and G3 to detect the JEV envelope (E) gene. The specific primer sets for JEV G1 and 1.0 2.0 2.0 G3 specifically amplified the target gene. The detection limits of the three primer sets were 10 , 10 , and 10 TCID50/ reaction, respectively. No cross-reactivity was detected with non-JEV reference viruses. The multiplex reverse transcription- polymerase chain reaction (RT-PCR) assay specifically differentiated JEV G1 from G3. Thus, a one-step multiplex RT-PCR assay was established to rapidly and differentially detect JEV. This assay will be useful for confirming JEV infections in animals and checking the JEV genotype in veterinary biological products. Key Words: Japanese encephalitis virus, Multiplex RT-PCR, Genotype infected mosquito bites. JE cases are traditionally identified INTRODUCTION in Asian countries, but 1.3% of blood donors in French Polynesia were seropositive for JEV between 2011 and 2013 Japanese encephalitis (JE) is a reemerging zoonosis (3), and JEV RNA was detected in C. -

A significantly higher proportion of the vector species that were initially attracted to a cow fed when released into a net with a cow than when released into a net containing a pig. However, Culex vishnui individuals that had been attracted to a pig had a higher feeding rate in a net containing a pig rather than a cow. When mosquitoes were given a choice by being released into a net containing both animals, they exhibited a tendency to feed on the host to which they had originally been attracted. -
Proposed Integrated Control of Zoonotic Plasmodium Knowlesi in Southeast Asia Using Themes of One Health
Tropical Medicine and Infectious Disease Review Proposed Integrated Control of Zoonotic Plasmodium knowlesi in Southeast Asia Using Themes of One Health Jessica Scott College of Public Health and Medical and Veterinary Sciences, Australian Institute of Tropical Health and Medicine, James Cook University, Townsville 4811, Australia; [email protected] Received: 25 September 2020; Accepted: 18 November 2020; Published: 20 November 2020 Abstract: Zoonotic malaria, Plasmodium knowlesi, threatens the global progression of malaria elimination. Southeast Asian regions are fronting increased zoonotic malaria rates despite the control measures currently implemented—conventional measures to control human-malaria neglect P. knowlesi’s residual transmission between the natural macaque host and vector. Initiatives to control P. knowlesi should adopt themes of the One Health approach, which details that the management of an infectious disease agent should be scrutinized at the human-animal-ecosystem interface. This review describes factors that have conceivably permitted the emergence and increased transmission rates of P. knowlesi to humans, from the understanding of genetic exchange events between subpopulations of P. knowlesi to the downstream effects of environmental disruption and simian and vector behavioral adaptations. These factors are considered to advise an integrative control strategy that aligns with the One Health approach. It is proposed that surveillance systems address the geographical distribution and transmission clusters of P. knowlesi and enforce ecological regulations that limit forest conversion and promote ecosystem regeneration. Furthermore, combining individual protective measures, mosquito-based feeding trapping tools and biocontrol strategies in synergy with current control methods may reduce mosquito population density or transmission capacity.

A MORPHOF ETRIC ANALYSIS OF THE CULICOIDES PULICARIS SPECIES COMPLEX (n.1'1 (DIPTERA: CERATOPOGONIDAE) ) stet '1+ nf ? 1`r3 I1 BY Richard Paul Lane, B.Sc. (London), A.R.C.S. A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College Department of Zoology and Applied Entomology, Imperial College, London, S.W.7. August 1979 ABSTRACT This study assesses the value of currently available multivariate morphometric techniques in the analysis of the Culicoides pulicaris complex. This midge complex is typical of species groups which are difficult to separate into discrete clusters (species). Initially, emphasis is given to the study of eight nominal taxa in Britain: C. delta Edwards, fagineus Edwards, grisescens Edwards, impunctatus Goetghebuer,.lupicaris Downes & Kettle, newsteadi Austen, pulicaris Linnaeus and punctatus Meigen. Subsequently, material from other parts of the Palaearctic Region is included. Morphological characters of adults are tested to evaluate the nature and extent of variation. Size is rejected as unreliable, since both intraspecific and seasonal variation is excessive. Allometry of size in legs, antennae and palps is studied in large homogeneous samples of three species and the implications for taxonomy discussed. A new system for coding wing pattern,utilising pattern elements, is developed and compared to a mechanical scanning method. The former, based on only 13 characters, is preferable, on practical and theoretical grounds, to the scanning method involving 420 characters. In constructing a classification, two points are considered. Firstly, whether a large number of characters is required for a reliable classification and secondly, whether the recognised species are homogeneous. -

The Dominant Anopheles Vectors of Human Malaria in the Asia-Pacific
Sinka et al. Parasites & Vectors 2011, 4:89 http://www.parasitesandvectors.com/content/4/1/89 RESEARCH Open Access The dominant Anopheles vectors of human malaria in the Asia-Pacific region: occurrence data, distribution maps and bionomic précis Marianne E Sinka1*, Michael J Bangs2, Sylvie Manguin3, Theeraphap Chareonviriyaphap4, Anand P Patil1, William H Temperley1, Peter W Gething1, Iqbal RF Elyazar5, Caroline W Kabaria6, Ralph E Harbach7 and Simon I Hay1,6* Abstract Background: The final article in a series of three publications examining the global distribution of 41 dominant vector species (DVS) of malaria is presented here. The first publication examined the DVS from the Americas, with the second covering those species present in Africa, Europe and the Middle East. Here we discuss the 19 DVS of the Asian-Pacific region. This region experiences a high diversity of vector species, many occurring sympatrically, which, combined with the occurrence of a high number of species complexes and suspected species complexes, and behavioural plasticity of many of these major vectors, adds a level of entomological complexity not comparable elsewhere globally. To try and untangle the intricacy of the vectors of this region and to increase the effectiveness of vector control interventions, an understanding of the contemporary distribution of each species, combined with a synthesis of the current knowledge of their behaviour and ecology is needed. Results: Expert opinion (EO) range maps, created with the most up-to-date expert knowledge of each DVS distribution, were combined with a contemporary database of occurrence data and a suite of open access, environmental and climatic variables. -
