COLLEGE STATION – Got mosquitoes? Thanks to a new Web-based mapping
system, you soon will be able to see if West Nile encephalitis or some
other mosquito-borne disease is in your neighborhood.
The Knowledge Engineering Lab in the department of entomology at Texas
A&M University is heading up the project to develop the statewide Mosquito
Spatial Information Management System. The real-time system -- that will
be available through the Internet -- will map disease occurrence,
epidemiology and control procedures, said Dr. Robert Coulson, Texas
Agricultural Experiment Station professor.
Based on similar maps developed last year for Brazos County by
Catherine Zindler, a Texas A&M entomology graduate student, the system
will allow health officials to target disease hot spots and determine
whether insecticides used for control are working
(
http://agnews.tamu.edu/dailynews/stories/ENTO/May2804a.htm).
Information will be contributed and made available to governmental
officials, state health officials and universities.
Coulson also expects the public to use the system as well.
"The idea behind that system is that it would facilitate planning,
problem solving and decision support in regard to mosquito-borne
diseases," Coulson said.
With insect-vectored diseases, "having reliable information that can be
addressed immediately in real time actually has a lot to do with response
time," he said.
For example, if health officials need to know how well a control
procedure works, the mapping system will allow quick access to that
information, he said.
The Web site will be easy to use. "If it is not user-friendly, people
will not use it," Coulson said. "The maps have to be presented where they
are useable and understandable by people."
This information is not available now, said Dr. Jim Olson, Experiment
Station entomologist.
The mapping system is part of a larger multi-agency project to
determine the incidence of mosquito-borne diseases and mosquito resistance
to insecticide, he said.
"In many parts of the state, we don't have a clue as to what level of
insecticide resistance exists," Olson said. "It's a bad time to find out
you've got it (resistance) in the middle of a disease outbreak. It is
better you take care of it well in advance."
The Experiment Station has developed a Mosquito Control Research
Initiative that will be submitted to the next session of the Texas
Legislature. The Experiment Station is asking for $1 million per year,
which would allow the agency to expand this and other mosquito-related
research programs, Olson said.
"This is a very important initiative," Coulson said. "Mosquito-borne
diseases affect practically all Texans in one way or another."
The information on the Web site will be available through maps and
text, he said.
"Much of the information, as much as 80 percent, of the information we
deal with is spatially referenced," Coulson said. "That is, it has a map
base to it. In this MTV world we live in today, people are very visually
oriented."
The Knowledge Engineering Lab would add information as it is needed.
This approach has been used for other insects and in other parts of the
United States, but Coulson said he knows of no such system for
mosquitoes-borne diseases.
However, he said the template they are using for their system can be
used in other places.
"Our focus now is on the state of Texas and the problems
mosquito-vectored diseases present to our citizens."
