In order to establish a workable control scheme of bitingmidge, this control program will be conducted in eight most epidemic counties, i.e., Taichung , Nantou, Changhua, Yunlin, Chiayi, Tainan , Hualian, and Taichung city, with the participation of communities, schools and sightseeing spots. Framework of the control program includes four parts; (1) monitoring of biting midge density and analyzing of its migration; (2) helping sightseeing spots to establish efficient control strategy through education, population dynamic studies, control strategy planning, public education and program evaluation, in order to establish integrated control models od bitingmidge in sightseeing spots; (3) Select sightseeing areas for prevention and demonstration unit, holding workshops for the environmental officals and the public, establishing long-term density surveillance with the assistance of local residents, and periodically visiting and discussing with local participants to promote the control practices; (4) publishing handbooks, brochures and CDs containing information of different midge species, for their general characteristics, life cycles, adult midge feeding patterns, female reproduction, fertility, larval habitat, chemical, physical control practices and other preventative measures, etc.; (5) holding biting midge prevention and treatment outcomes publication ceremony to enhance the participation of researchers and communities, schools and sightseeing spots which have effective prevention and treatment to share control strategy. At the same time information will help the center with its future planning. (6) Biting Midge Control and Extension Center will update its website and offer special line services to provide related information and control tactics, establish the platform for standard operation procedures. A direct telephone line will also be at service upon request. (7) Program is finished writing the results report, to review the case and control the effectiveness of the implementation plan and conduct a comprehensive assessment. The ultimate goal of this project is to aim at sightseeing spots to decrease the density and occurrence of biting midge, and propose efficient control strategy.
