The City of Barcelona uses Tigatrapp, a mobile device application for tracking and preventing spread of the tiger mosquito

The Barcelona Pubic Health Agency (ASPB) has joined the  project and is promoting the mobile device application Tigatrapp throughout the city. The city aims to encourage citizen use of the application in order to gain information about the distribution of the tiger mosquito and particularly about potential breeding sites. The web site provides detailed information about this scientific initiative which has improved observation and control of this species that has already existed in Barcelona for 10 years.

Participation of citizens with mobile devices will help uncover many more details about possible tiger mosquito breeding sites in different parts of the city, especially places or containers where the mosquitos are reproducing and larvae are found; common examples include drainages, ornamental fountains, barrels, etc.

All data received via the application, including georeferenced photographs, are provided openly and in real time in interactive maps at the web page

Public services in Barcelona for monitoring and control of the pest species in public space fall to the Barcelona Public Health Agency; the Agency will use maps generated by the initiative for prioritizing and organizing different pest monitoring and control activities undertaken within the city.

The Tigatrapp mobile application was developed for the initiative, a citizen science project coordinated by the Movement Ecology Lab of the Blances Center for Advanced Studies of the Spanish Council for Scientific Research (CEAB-CSIC) and CREAF.

The head of the Barcelona Public Health Agency’s Tiger Mosquito Monitoring and Control Program, Tomás Montalvo, explains that this tool “will make valuable information available for improving monitoring and control of this species in the city. We need to remember that preventing the pest’s spread is everyone’s responsibility, especially since this species mostly reproduces on private properties where it finds a large variety of small containers which can at times contain water.” He adds, “projects like this one are contributing in an important way to improving citizen coexistence and quality of life in Barcelona.”

ICREA research professor, CREAF associate researcher and director of, Frederic Bartumeus, promotes collaboration with citizens: “we are aiming for a kind of citizen science and management model which is participative and open, where citizens, scientists, and prevention agencies work together to minimize problems associated with the presence of this invasive species.” The creators of the project explain that this “will lead to the creation of models which permit the prediction of populations of tiger mosquito in the city, combining the citizen contribution with data from the Public Health Agency.”

Currently, the project has support of Obra Social “la Caixa” and the program Ayudas a la Investigación Recercaixa, the Spanish Ministry of Economy and Competitiveness, and the company Lokímica. It has also received support from the Spanish Foundation for Science and Technology (FECYT) and the brand Bloom.

A species whose spread must be prevented

The tiger mosquito (Aedes albopictus) is an exotic invasive species that causes bothersome bites and is capable of transmitting diseases under certain conditions. It lives in urban areas, flies low to the ground, and bites during the day. Characteristics for identification include its black color with white stripes and a white line on the upper side which passes down the head and thorax.

The most efficient waytoprevent spread of the tiger mosquito is to prevent its reproduction by doing away with its breeding sites. The tiger mosquito lays its eggs in small containers with water. Considering that it reproduces mostly on private property, the most important thing is to not allow water to accumulate in containers at home, including pots, buckets, barrels, watering cans, small pools, etc.

A years-long monitoring campaign

Barcelona Public Health Agency (ASPB) has hada program for control of the tiger mosquito in the public spacesince 2005. Thanks to this program, awareness is spread to citizens, continuous monitoring is underway in different risk areas (there are 68 risk zones in 2015), and cases of arboviruses within the city are monitored and controlled to avoid potential transmission of diseases. Each year the ASPB manages around 250 incidents related to the tiger mosquito, leading to around 800 control interventions.
