Description: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.
