Abstract This report describes the presence of Aedes albopictus Skuse (Diptera: Culicidae) in Yucatan Peninsula and represents the first record of the Asian tiger invasive mosquito in Campeche State, southeastern Mexico. We collected specimens using 11,326 ovitraps put into houses of urban and rural areas, as part of the entomological surveillance by the local Ministry of Health from January 2019 to February 2020. We found Ae. albopictus in five of the 12 municipalities of Campeche (San Francisco de Campeche, Tenabo, Hecelchakán, Calkíni and Escárcega). We record 68 positive ovitraps and 226 Ae. albopictus larvae. This finding increases the number of mosquito species recorded in Campeche, Mexico, and possibly the potential for 22 arbovirus transmission.

This study of mosquitoes in Lika, geographically, geologically and climatically a very specific region, was conducted to gain insight into the composition and relative abundance of the mosquito fauna, as well as to check for the possible presence of invasive species. Sampling took place from July to September 2020. Mosquito larvae were captured from medium and small breeding sites using a 25 cm diameter net and a plastic dipper. Adult specimens were sampled in both urban and rural areas using CO2 baited CDC traps, CO2 baited BG Sentinel traps with BG Lure and human landing catch. The study was conducted at 69 sites. We collected 5,126 specimens (100 adults and 5,026 larvae) and demonstrated the presence of 16 mosquito species. CDC traps were almost five times more effective (quantity and quality) than BG Sentinel traps. The most common mosquito taxa caught in Lika were Culex pipiens complex (78.36% of all larvae) and Ae. geniculatus (30.26% of all adults). Both invasive mosquito species present in Croatia, Aedes albopictus and Ae. japonicus, were recorded, with Ae. albopictus being detected in Lika for the first time. Aedes japonicus was widespread, recorded in 23 localities. According to molecular analysis, only An. maculipennis s.s. was confirmed in the An. maculipennis complex. Within the Cx. pipiens complex, both Cx. pipiens biotypes, pipiens and molestus were confirmed together with one single hybrid specimen. Analysis of mosquito occurrence with regard to altitude shows that most samples and species were collected between 601 and 700 m a.s.l., although the Shannon evenness index and Hill’s index show the highest value in the range of 901 to 1140 m a.s.l. In this systematic study on the mosquito fauna in Lika, a significant species diversity, including invasive species, was found.

Economic Use

Red algae are the most conspicuous component in algal drifts that periodically arrive on the coasts of the Yucatan Peninsula. Given the presence of agars and carrageenans in their cell wall and the synthesis of secondary metabolites that act as antitumors or antioxidants, most of these species are highly valued in the international market. However, in this region of Mexico they are not used but represent a problem of waste from beaches. Our aim was to determine the composition of marine red algae of economic use in the algal drifts of the Yucatan Peninsula, providing brief descriptions, photographs that facilitate their identification and possible explanations for their causes and routes of origin. 13 samplings were carried out at 14 sites, collecting fresh and complete thalli from which the species of economic importance were described. 24 species distributed in six orders and seven families were identified. The most abundant families for both the number of species and the amount of biomass were Gracilariaceae (10 species), Rhodomelaceae (6 species) and Solieriaceae (3 species). The localities with the greatest diversity and biomass were those belonging to Campeche: Sabancuy (11 species), Punta Xen (14 species), Tortuga Bay (13 species) and Playa Bonita (13 species). From the present study we contributed six new records endemic to Campeche, including the first record of the genus Codiophyllum for the Western Atlantic Ocean. Our data on diversity, biomass, periodicity and growth rates of red algal drifts allow us to suggest that the Campeche and Yucatan drifts are a sustainable source of raw material.

Abstract BackgroundIn Europe, Ae. albopictus is an important vector of chikungunya virus, Dirofilaria nematodes and was involved in local autochthonous circulation of dengue virus and Zika virus. Due to the ongoing spread, a targeted field surveillance at potential points-of-entries for Aedes invasive mosquitoes was initiated for the Republic of Moldova in 2020 as part of the transboundary “Aedes Invasive Mosquito COST Action project”. MethodsIn 2020, ovitraps were positioned at each of three locations: the border crossing to Romania in Leuseni (Hancesti region), Chisinau International Airport and Chisinau Botanical Garden.ResultsA total of 188 Aedes spp. eggs were collected at the Chisinau International Airport between August and September 2020. Twenty-three adults reared in the laboratory were identified morphologically as Aedes albopictus (Skuse, 1895) and twelve selected specimens were confirmed by molecular barcoding of the cytochrome oxidase subunit I gene region. In addition, one adult female of Ae. albopictus was caught at the same site with a manual aspirator from a human.ConclusionsThis is the first documented report of Ae. albopictus in the Republic of Moldova. The presence of immature and adult stages indicates the local reproduction of the species in the country. Therefore, it is crucial to extend and strengthen surveillance of the invasive Aedes mosquitoes to prevent Ae. albopictus and other exotic mosquito species from establishing in the Republic of Moldova.

Se expone la primera cita de Aedes (Fredwardsius) vittatus (Bigot, 1861) en la comunidad autónoma de Galicia, conseguida gracias a la plataforma de ciencia ciudadana Mosquito Alert. Aun cuando este proyecto está enfocado hacia la detección y seguimiento de dos especies de culícidos exóticos invasores: Aedes (Stegomyia) albopictus (Skuse 1894) y Aedes (Stegomyia) aegypti (L.), se evidencia la gran capacidad existente para el estudio de la biodiversidad así como la detección de otras especies por parte de plataformas que se apoyan en miles de ciudadanos motivados y un equipo experto. We present here the first record of Aedes (Fredwardsius) vittatus (Bigot, 1861) in the autonomous region of Galicia, obtained by the means of the citizen science project Mosquito Alert. Whereas this project only aims to the monitoring and early detection of the two invasive mosquito species Aedes (Stegomyia) albopictus (Skuse 1894) and Aedes (Stegomyia) aegypti (L.), it is worth noting its capacities in regards to the general biodiversity study and the detection of mosquito species if a large pool of users combines with the expert knowledge.

Abstract Aedes vittatus Bigot is distributed throughout Africa, tropical Asia, and southern Europe and occurs in sylvatic as well as peridomestic environments where it readily feeds on humans. Although the vectorial capacity of Ae. vittatus is not well understood, this species is known to play a role in the maintenance and transmission of yellow fever, Zika, chikungunya, and dengue virus within its native range. In October 2019, after a routine inspection of mosquito-breeding containers in Jarabacoa, Dominican Republic, two Ae. vittatus females were captured via human landing catch method. After this finding, a CDC miniature light trap was deployed at the point of initial detection from 18:00 to 08:00 h, 2 d/wk from 3 to 31 October 2019. Potential larval habitats were also sampled via traditional dip method once per week spanning a 150 m radius from point of initial detection. In addition to the 2 adult females, 10 female and 2 male Ae. vittatus were captured. One Ae. vittatus larva also was found in a small puddle formed by an animal hoof print. Conventional PCR and Sanger sequencing were used to confirm morphological identification of collected specimens. This is the first detection of Ae. vittatus in the Dominican Republic as well as the Americas. Therefore, enhanced surveillance is needed to better understand the range and public health risks this potential invasive mosquito species may pose in the Dominican Republic, other Caribbean Islands, and/or the Americas.

Background: Mosquitoes are responsible for spreading devastating parasites and pathogens causing some important infectious diseases. The present study was done to better understand and update the fauna of Culicidae and to find out the distribution and the type of their larval habitats in Kashan County. Methods: This study was done in four districts of Kashan County (Central, Qamasr, Niasar and Barzok). Mosquito lar-vae were collected from 23 active larval habitats using a standard 350ml capacity mosquito dipper from April to late December 2019. The collected larvae were transferred to containers containing lactophenol, and after two weeks indi-vidually mounted in Berlese's fluid on a microscope slide and identified to species by morphological characters and valid keys. Results: In this study, a total of 9789 larvae were collected from urban and rural areas in Kashan County. The identified genera were Anopheles, Culiseta and Culex. In this study larvae of An. turkhudi, Cx. perexiguus, Cx. mimeticus, Cx. deserticola and Cs. subochrea were collected for the first time from Kashan County. Conclusion: The results of this study indicate the presence and activity of different mosquito species in Kashan County that some of them are vectors of arbovirus and other vector-borne diseases.

Alien mosquito and vertebrate host species may create novel epidemiological scenarios for the transmission of pathogens naturally circulating in the invaded area. The exotic Monk parakeet (Myiopsitta monachus) has established populations in Europe and is currently considered an invasive pest. Due to their high abundance in urban areas, Monk parakeets could be involved in the transmission of pathogens, potentially affecting wildlife and livestock. To test this hypothesis, we determined the prevalence and diversity of three vector-borne parasites, namely Plasmodium, Haemoproteus and Leucocytozoon, in Monk parakeets from Barcelona. Many areas of southern Europe shelter high densities of the invasive Asian tiger mosquito Aedes albopictus, which in addition to native mosquito species could affect the transmission of mosquito-borne parasites, such as avian Plasmodium. Thus, we also sampled mosquitoes in the area to trace their blood-feeding hosts and determine the presence of Plasmodium parasites. Monk parakeets were neither infected by Plasmodium nor by Haemoproteus parasites, and only five individuals (3.13%; n = 160) were infected by Leucocytozoon. Monk parakeets were bitten by Culiseta longiareolata and represented 9.5% of Culex pipiens blood meals. The invasive Ae. albopictus showed a clear anthropophilic feeding pattern, with humans dominating its diet. Three Plasmodium lineages were detected in pools of Cx pipiens. These results suggest that Plasmodium circulating in the area cannot develop in the invasive Monk parakeet, in spite of the relatively high fraction of native mosquito vectors feeding on this species in its invaded distribution range.

AbstractAtypical colorations occur in different groups of vertebrates. The loss of melanin in the skin, hair and eyes is the result of an autosomal recessive genetic entity. It causes individuals to present with a white coloration of the skin and hair, as well as red eyes, known as albino. This manuscript documents the first record in Mexico of complete albinism in a marsupial, Didelphis virginiana, captured in the Yucatan peninsula.

Invasive Mosquito

Climate change, urbanization, and financial crisis have created a dramatic mixture of challenges in Southern Europe, increasing further the risks of transmission of new vector-borne diseases. In the last decade, there has been a wide spread of an invasive mosquito species Aedes albopictus, commonly known as the Asian tiger mosquito, in various urban ecosystems of Greece accompanied by greater risks of infectious diseases, higher nuisance levels, and increased expenses incurred for their control. The aim of the present paper is to investigate citizens’ perception of the Aedes albopictus problem and to evaluate various policy aspects related to its control. Findings are based on the conduct of a web-based survey at a national scale and the production of national surveillance maps. Results indicate that citizens are highly concerned with the health risks associated with the new mosquito species and consider public prevention strategies highly important for the confrontation of the problem while, at the same time, surveillance maps indicate a constant intensification of the problem. The spatial patterns of these results are further investigated aiming to define areas (regions) with different: (a) Levels of risk and/or (b) policy priorities. It appears that citizens are aware of the invasive mosquito problem and appear prone to act against possible consequences. Climate change and the complex socio-ecological context of South Europe are expected to favor a deterioration of the problem and an increasing risk of the transmission of new diseases, posing, in this respect, new challenges for policy makers and citizens.
