“…The results in this study show a higher infection rate by DENV-1 and CHIKV in A. albopictus (Table 2) compared to A. aegypti. This does not agree with the values previously reported since the MIR values in A. aegypti are higher (Guerbois et al, 2016;Huerta et al, 2017;Garcia-Rejon et al, 2018). However, it was experimentally shown that A. albopictus is a vector more susceptible to infection than A. aegypti because the arbovirus dissemination rates were higher in nearly all strains of A. albopictus tested (Turell et al, 1992).…”

“…Alternatively, ZIKV has a MIR value ranging from 3 to 17 individuals and CHIKV ranges from 2 to 3 individuals. Finally, for MAYV, the only reported value is 1.75 (Diallo et al, 2014;Guerbois et al, 2016;Huerta et al, 2017;Cevallos et al, 2018;Eiras et al, 2018;Garcia-Rejon et al, 2018). These data show that A. aegypti presents a higher rate of natural infection by arboviruses compared to A. albopictus and this is attributed to the greater presence of this species in urban areas, which indicates that A. aegypti is the main vector of arboviruses and A. albopictus is the secondary vector in Latin America (Black et al, 2002;Paupy et al, 2009).…”

“…DENV-1 was the arbovirus with the highest frequency in the population of infected individuals at 82% (50/61) and the overall infection rate in A. aegypti and A. albopictus was 29.6% (50/169) ( Table 2). The DENV-1 serotype has also been detected more frequently than other arboviruses in Indonesia, Mexico, Cuba, Brazil, and Colombia (Velandia-Romero et al, 2017;Eiras et al, 2018;Garcia-Rejon et al, 2018;Gutiérrez-Bugallo et al, 2018;Rahayu et al, 2019). The high frequency of this arbovirus may be because the transmission in the urban cycle of DENV is provided by the level of viremia of the hosts (humans) since individuals at the beginning of infection have high rates of viremia (Duong et al, 2015;Martínez-Vega et al, 2015).…”

The identification of vector species and their natural infection with arboviruses results in important data for the control of their transmission. However, for the eastern region of Colombia, this information is limited. Therefore, this study morphologically and molecularly identified species of the genus Aedes and the detection of arboviruses (Dengue, Chikungunya, Zika, and Mayaro) in female mosquitoes (individually) present in three municipalities (Saravena, Arauquita, and Tame) by amplifying the genetic material using RT-PCR (reverse transcriptase polymerase chain reaction) in the department of Arauca, eastern Colombia. Inconsistencies between morphological and molecular identification were detected in 13 individuals with Aedes albopictus initially determined as Aedes aegypti based on morphology (n = 13). Molecular identification showed the simultaneous presence of A. aegypti (n = 111) and A. albopictus (n = 58) in the urban municipalities of Saravena and Arauquita. These individuals were naturally infected with Dengue virus type 1 (DENV-1) and Chikungunya virus (CHIKV). The most frequent arbovirus was DENV-1 with an infection rate of 40.7% (11/27) for A. aegypti and 39.7% (23/58) for A. albopictus, which was followed by CHIKV with an infection rate of 1.8% for A. aegypti (2/111) and 6.9% for A. albopictus (4/58). Additionally, a mixed infection of DENV-1 and CHIKV was obtained in 4.5% of A. aegypti (5/111). Zika virus (ZIKV) and Mayaro virus (MAYV) infections were not detected. This study found that barcoding (fragment gene COI) is a successful method for identifying Aedes species. Additionally, we recommend the individual processing of insects as a more accurate strategy for arboviruses detection since the infection rate is obtained and co-infection between DENV-1 and CHIKV is also possible.

This study was designed to assess whether churches in endemic dengue districts in Merida, Mexico provide suitable breeding habitats for mosquitoes and are potential sites for dengue virus (DENV) transmission. Churches were inspected for immature and adult mosquitoes once every week from November 2015 to October 2016. A total of 10,997 immatures of five species were collected. The most abundant species were Aedes aegypti (6,051) and Culex quinquefasciatus (3,018). The most common source of immature Ae. aegypti were buckets followed by disposable containers. Adult collections yielded 21,226 mosquitoes of nine species. The most common species were Cx. quinquefasciatus (15,215) and Ae. aegypti (3,902). Aedes aegypti were found all year long. Female Ae. aegypti (1,380) were sorted into pools (166) and assayed for flavivirus RNA by RT-PCR and Sanger sequencing. Two pools were positive for DENV (DENV-1 and 2). In conclusion, we demonstrated that some churches in Merida are infested with mosquitoes all year long and they potentially serve as sites for DENV transmission and should therefore be considered for inclusion in mosquito and arboviruses control and surveillance efforts.

Objective To investigate the presence and abundance of mosquito species in containers found in different types of cemeteries in Puerto Rico to assess their importance and make control recommendations. Methods We conducted surveys of containers with water in 16 cemeteries in southeastern Puerto Rico to detect the presence of larvae and pupae of Aedes aegypti and other mosquitoes; to identify the most common and productive containers and to study their variation in relation to the type of cemetery. Results The most common containers with water were flowerpots, followed in abundance by a variety of discarded containers and open tombs. We found a positive relationship between density of containers with water and rainfall. There was a rich community of mosquito species developing in containers of the inspected cemeteries: nine mosquito species belonging to four genera with Ae. aegypti and Ae. mediovittatus being the most frequent and abundant. We sampled 13 cement‐type cemeteries, 2 mixed and only 1 lawn cemetery, consequently, we could not draw any conclusion regarding container productivity and cemetery type. Conclusions Surveyed cemeteries were important sources of Ae. aegypti and other mosquitoes in flowerpots, discarded containers and open tombs. We recommend conducting further studies to establish how frequently inspections should occur; and mosquito control by emptying aquatic habitats and larviciding to reduce mosquito productivity and protect workers and visitors from mosquito bites and possible transmission of arboviruses.
