  • Distribution and Abundance of Aedes (Finlaya) Japonicus Japonicus (Theobald) in Five Districts on the Island of Hawaii
    Aproceedingsedes j. jAponicus of the in h HAawaiiwAiiAn entomologicAl society (2010) 42:9–14 9 Distribution and Abundance of Aedes (Finlaya) japonicus japonicus (Theobald) in Five Districts on the Island of Hawaii Linda Burnham Larish1,3, Pingjun Yang2, and Bernard A. Asuncion1 Hawaii State Department of Health, Vector Control Branch, 11582 Kamehameha Avenue, Hilo, HI 96720; 2Vector Control Branch, 99-945 Halawa Valley Street, Aiea, HI 96701. 3Present address: PO Box 1337, Keaau, HI 96749; e-mail: [email protected] Abstract. Subsequent to the detection of Aedes (Finlaya) japonicus japonicus (Theo- bald) on the island of Hawaii, a survey was conducted over the span of twelve months from June 2005 until June 2006, to determine its distribution and abundance on the island. Ae. j. japonicus was the third most abundant species encountered employing gravid traps and the fourth most abundant using New Jersey light traps in the districts surveyed. In addition, gravid mosquito traps which used a bait of infused leaf detritus were more effective at catching Ae. j. japonicus than New Jersey light traps. Key words: Aedes japonicus japonicus, Hawaii, gravid traps, New Jersey light traps Introduction Since the arrival of Europeans to the Hawaiian Islands in the late 1700s, there has been a rapid increase in the flow of alien arthropod species into the islands. Hawaii was without mosquitoes until 1826 when Culex quinquefasciatus was accidentally introduced (Hardy 1960). Aedes aegypti was first noticed in 1892 and closely followed by Aedes albopictus in 1986 (Hardy 1960). There were no further mosquito introductions until 1962, when Aedes vexans nocturnus was found on the island of Oahu (Joyce and Nakagawa 1963).

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.

It is largely linked to the spread of the main arbovirus vectors, invasive mosquito of the genus Aedes. Previously, it has been reported that Aedes aegypti reemerged in Russia after a 50-year absence. Moreover, in 2011, Ae. albopictus was registered in the city of Sochi (South Russia, Black Sea coast) for the first time. In 2013, Asian Ae. koreicus was found in Sochi for the first time. Methods: Mosquitoes were collected using the following methods: larvae with a dip net, imago on volunteers and using bait traps. The mosquitoes were identified using both morphology and sequencing of the second internal transcribed spacer of the nuclear ribosomal RNA gene cluster. Results: In August 2016, Ae. koreicus larvae and imago and a single male of Ae. aegypti were found on the southern coast of the Crimean Peninsula, where they were not registered before. Newly obtained DNA sequences were registered in GenBank with the accession numbers MF072936 and MF072937.

Parasites Vectors (2019) 12:120 https://doi.org/10.1186/s13071-019-3387-x Parasites & Vectors RESEARCH Open Access The invasive mosquito Aedes japonicus japonicus is spreading in northeastern Italy Fabrizio Montarsi1, Simone Martini2, Alice Michelutti1, Graziana Da Rold1, Matteo Mazzucato1, Davide Qualizza3, Domenico Di Gennaro3, Marcella Di Fant3, Marco Dal Pont4, Manlio Palei5 and Gioia Capelli1* Abstract Background: The invasive mosquito species, Aedes japonicus japonicus, was detected in northeastern Italy for the frst time in 2015, at the border with Austria. After this fnding, a more intensive monitoring was carried out to assess its distribution and to collect biological data. Herein, we report the results of four years (2015–2018) of activity. Methods: The presence of Ae. j. japonicus was checked in all possible breeding sites through collections of larvae. The monitoring started from the site of the frst detection at the Austrian border and then was extended in all directions. The mosquitoes were identifed morphologically and molecularly. Results: Aedes j. japonicus was found in 58 out of 73 municipalities monitored (79.5%). In total (2015–2018), 238 sampling sites were monitored and 90 were positive for presence of Ae. j. japonicus larvae (37.8%). The mosquito was collected mainly in artifcial containers located in small villages and in rural areas. Cohabitation with other mosquito species was observed in 55.6% of the samplings. Conclusions: Aedes j. japonicus is well established in Italy and in only four years has colonised two Italian Regions, displaying rapid spreading throughout hilly and mountainous areas. Colonization towards the south seems limited by climatic conditions and the occurrence of a large population of the larval competitor, Ae.

  • Laboratory Colonization of the European Invasive Mosquito Aedes (Finlaya) Koreicus Silvia Ciocchetta1,2* , Jonathan M
    Ciocchetta et al. Parasites & Vectors (2017) 10:74 DOI 10.1186/s13071-017-2010-2 SHORT REPORT Open Access Laboratory colonization of the European invasive mosquito Aedes (Finlaya) koreicus Silvia Ciocchetta1,2* , Jonathan M. Darbro1, Francesca D. Frentiu2, Fabrizio Montarsi3, Gioia Capelli3, John G. Aaskov2 and Gregor J. Devine1 Abstract Background: Aedes (Finlaya) koreicus (Edwards) is a mosquito that has recently entered Europe from Asia. This species is considered a potential threat to newly colonized territories, but little is known about its capacity to transmit pathogens or ability to compete with native mosquito species. The establishment of a laboratory colony is a necessary first step for further laboratory studies on the biology, ecology and vector competence of Ae. koreicus. Results: A self-mating colony was established at QIMR Berghofer Medical Research Institute (Brisbane, Australia) from eggs of the F1 progeny of individuals collected as free-living larvae in northeastern Italy (Belluno province). Mosquitoes are currently maintained on both defibrinated sheep blood provided via an artificial membrane system and human blood from volunteers. Larvae are maintained in rain water and fed with Tetramin® fish food (©2015 Spectrum Brands - Pet, Home and Garden Division, Tetra-Fish). Morphometric measurements related to body size were taken and a fecundity index, based on wing length, was calculated. An in vivo technique for differentiating male and female pupae has been optimized. Our findings provide the basis for further studies on the ecology and physiology of Ae. koreicus. Conclusion: We describe the establishment of an Ae. koreicus colony in the laboratory and identify critical requirements for the maintenance of this mosquito species under artificial conditions.

  • Pathways for Introduction and Dispersal of Invasive Aedes Mosquito Species in Europe: a Review Adolfo Ibáñez-Justicia 1
    1 Pathways for introduction and dispersal of invasive Aedes mosquito species in Europe: a review Adolfo Ibáñez-Justicia 1 1 Centre for Monitoring of Vectors (CMV), Netherlands Food and Consumer Product Safety Authority (NVWA), Geertjesweg 15, 6706 EA Wageningen, The Netherlands. Corresponding author: [email protected] First published online: 17th December 2020 Abstract: In the last decades, Aedes invasive mosquito species (AIMs) have arrived in Europe from overseas, introduced via different pathways. Several species such as Aedes albopictus, Ae. japonicus and Ae. koreicus were introduced, built populations, and expanded their distribution into new regions. The introduction and establishment of AIMs in Europe is a risk to public health, due to the ability of these mosquitoes to transmit diverse pathogens of vector-borne diseases. The objective of this manuscript is to review knowledge of pathways associated with the introduction and dispersal of AIMs in Europe. The identification of pathways for introduction of AIMs is critical to decide on surveillance strategies needed to reduce the risk and control future introductions. Four main routes are identified and discussed: the passive transport of AIMs via (1) the trade of used tyres, (2) the trade of Lucky bamboo plant cuttings, (3) vehicles (traffic by road, airplanes, and sea), as well as (4) the active natural dispersal of AIMs. We conclude that the trade of used tyres remains the main pathway for long distance transportation and introduction of AIMs into and within Europe. Furthermore, passive transport by road in ground vehicles (e.g. car, truck) represents the major driving force for dispersion from already established populations.

These freshwater macroinvertebrates are predators and parasites of the equally diverse nematocerous Dipterans, such as mosquitoes, and water mites are believed to have diversified as a result of these predatory and parasitic relationships. Through these two major biotic interactions, water mites have been found to greatly impact a variety of mosquito species. Although these predatory and parasitic interactions are important in aquatic ecology, very little is known about the diversity of water mites that interact with mosquitoes. In this paper, we review and update the past literature on the predatory and parasitic mite–mosquito relationships, update past records, discuss the biogeographic range of these interactions, and add our own recent findings on this topic conducted in habitats around the Laurentian Great Lakes.
