En 2016 se estableció un sistema anual de vigilancia entomológica para la detección de Aedes albopictus en la comunidad autónoma de La Rioja. En el verano de 2020, se detectó por primera vez la presencia de huevos en una zona urbana, lo que constituye el primer registro de esta especie en la región. La identificación de este mosquito invasor supone un cambio en el riesgo de aparición de casos de arbovirosis en La Rioja. La vigilancia entomológica es crucial para el diseño de estrategias de control que, junto con la vigilancia epidemiológica, puedan evitar la aparición de brotes autóctonos de arbovirosis. En este trabajo se detalla el proceso de la primera detección de mosquito tigre en La Rioja, así como las intervenciones llevadas a cabo y las perspectivas de futuro. In 2016, an annual entomological surveillance program for the detection of Aedes albopictus in the autonomous community of La Rioja was established. In the summer of 2020, the presence of eggs was detected for the first time in an urban area, which constitutes the first record of this species in the region. The identification of this invasive mosquito implies a change in the risk of occurrence of arbovirus cases in La Rioja. Entomological surveillance is crucial for the design of control strategies that, together with epidemiological surveillance, can prevent the appearance of autochthonous arbovirus outbreaks. This work is a detailed description of the first detection of tiger mosquito in La Rioja, as well as the completed interventions, and the perspectives for the future.

ABSTRACT The invasive mosquito Aedes albopictus is currently distributed in most of the southern Mexican region. Since the species was first recorded in the state of Tamaulipas, in northeastern Mexico in 1988, it has expanded its distribution throughout the Sierra Madre Oriental and Gulf of Mexico to the Neotropical region of the country. Currently the species occurs in the states of Tamaulipas, Coahuila, Nuevo Leon, Veracruz, Chiapas, Morelos, Quintana Roo, Sinaloa, San Luis Potosi, and Hidalgo. This is the first report of the mosquito in the states of Tabasco and Yucatan and the confirmation of its presence in Quintana Roo state. Aedes albopictus has been incriminated as a secondary vector of diseases such as those caused by dengue, chikungunya, and Zika viruses, which have caused epidemic outbreaks in most tropical and subtropical regions of Mexico; therefore, surveillance for the detection of Ae. albopictus is paramount so that targeted control strategies can be implemented for its control throughout Mexico.

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.

ABSTRACT Aedes albopictus is an important vector of several arboviruses that affect human health worldwide; thus, knowledge of its distribution is a key factor for the implementation of disease control strategies. In Mexico, Ae. albopictus was recorded for the first time in 1988 in Tamaulipas State (northeast), but currently it has been recorded in 14 of the 32 states in the country. In 2012, it was recorded for the first time in a single locality in Quintana Roo (Cancún). In this study, we provide new distribution information for Ae. albopictus in the center and south of Quintana Roo State and comment on its medical importance.

Abstract Background : Aedes aegypti is an important vector for transmission of some dangerous arboviral diseases including Dengue Fever. This study was conducted for the first time in Iran in order to survey the existence of this invasive species in oriental parts of the country located near the Persian Gulf during August 2017 to January 2020. Methods : Different sampling methods were used to collect all stages of mosquitoes in five selected cities of Hormozgan province, south of Iran. After morphological identification, a molecular study based on Cytochrome Oxidase (CO1) gene-specific primers was performed to identify them more precisely. Then, the CO1 gene were sequenced via the Sanger method. Results : Totally, 4560 adults and 3520 larvae were collected from all sampling areas. Thirty-one Aedes aegypti specimens were identified from Bandar Khamir and Bandar Lengeh seaports. Conclusion : Based on the biology and ecology of Aedes aegypti , the possibility of establishment of this species in this region is very high due to the tropical climate of this region. Considering the detection of this invasive vector, high incidence of some arboviral diseases in the neighboring countries, and continuous movements of the settlers of these areas, some potential outbreaks of arboviral diseases can be predicted. Thus, planning and implementing an immediate preventative and surveillance program is vital in order to prevent the establishment of this invasive vector in this area.

Transovarial transmission (TOT) of dengue virus (DENV) in Aedes spp. is an important mechanism for DENV maintenance in nature and may be important in initiating outbreaks. The objective of this study was to explore the occurrence of TOT in wild Aedes albopictus populations in Cuba. Mosquito larvae were collected in Cotorro municipality, Havana, Cuba, and identified to species. Fifteen pools of Ae. albopictus each containing 30 larvae were processed for DENV detection by using conventional RT-PCR and nested PCR. Four out of 15 pools processed were positive for DENV-3, but no other DENV serotype was detected. This is the first time TOT of DENV detected in Cuban field populations of Ae. albopictus, and this suggests that this species may be an important vector of DENV in Cuba.

Insecticide resistance is an increasing problem worldwide that limits the efficacy of control methods against several pests of health interest. Among them, Aedes albopictus mosquitoes are efficient vectors of relevant pathogens causing animal and human diseases worldwide, including yellow fever, chikungunya, dengue, and Zika. Different mechanisms are associated in conferring resistance to chemical insecticides. One of the most widespread and analysed mechanisms is the knockdown resistance (kdr) causing resistance to DDT and pyrethroids. The mechanism is associated with mutations in the voltage sensitive sodium channel, which is involved in beginning and propagation of action potentials in nervous cells. The mechanism was originally discovered in the housefly and then it was found in a large number of arthropods. In 2011, a kdr associated mutation was evidenced for the first time in A. albopictus and afterward several evidences were reported in the different areas of the world, including China, USA, Brazil, India, and Mediterranean Countries. This review aims to update and summarize current evidences on kdr in A. albopictus, in order to stimulate further researches to analyse in depth A. albopictus resistance status across the world, especially in countries where the presence of this vector is still an emerging issue. Such information is currently needed given the well-known vector role of A. albopictus in the transmission of severe infectious diseases. Furthermore, the widespread use of chemical insecticides for control strategies against A. albopictus progressively lead to pressure selection inducing the rise of insecticide resistance-related mutations in the species. Such event is especially evident in some countries as China, often related to a history of uncontrolled use of chemical insecticides. Thus, a careful picture on the diffusion of kdr mutations worldwide represents a milestone for the implementation of control plans and the triggering of novel research on alternative strategies for mosquito-borne infections.
