Cemeteries as sources of Aedes aegypti and other mosquito species in southeastern Puerto Rico
Otero LM , Medina-Martinez G , Seplveda M , Acevedo V , Toro M , Barrera R . Trop Med Int Health 2022 27 (3) 300-309 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; identify the most common and productive containers and 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. |
Microbial Diversity of Adult Aedes aegypti and Water Collected from Different Mosquito Aquatic Habitats in Puerto Rico
Caragata EP , Otero LM , Tikhe CV , Barrera R , Dimopoulos G . Microb Ecol 2021 83 (1) 182-201 Mosquitoes, the major vectors of viruses like dengue, are naturally host to diverse microorganisms, which play an important role in their development, fecundity, immunity, and vector competence. The composition of their microbiota is strongly influenced by the environment, particularly their aquatic larval habitat. In this study, we used 2×300 bp 16s Illumina sequencing to compare the microbial profiles of emerging adult Aedes aegypti mosquitoes and the water collected from common types of aquatic habitat containers in Puerto Rico, which has endemic dengue transmission. We sequenced 141 mosquito and 46 water samples collected from plastic containers, septic tanks, discarded tires, underground trash cans, tree holes, or water meters. We identified 9 bacterial genera that were highly prevalent in the mosquito microbiome, and 77 for the microbiome of the aquatic habitat. The most abundant mosquito-associated bacterial OTUs were from the families Burkholderiaceae, Pseudomonadaceae, Comamonadaceae, and Xanthomonadaceae. Microbial profiles varied greatly between mosquitoes, and there were few major differences explained by container type; however, the microbiome of mosquitoes from plastic containers was more diverse and contained more unique taxa than the other groups. Container water was significantly more diverse than mosquitoes, and our data suggest that mosquitoes filter out many bacteria, with Alphaproteobacteria in particular being far more abundant in water. These findings provide novel insight into the microbiome of mosquitoes in the region and provide a platform to improve our understanding of the fundamental mosquito-microbe interactions. |
