We developed two kinds of selective mosquito traps. The first selective mosquito trap called Mos-hole was developed with emitting carbon dioxide. The principle was that CO2 gas was obtained from burning liquid naphtha. The process principle was very unique that some heat and moisture which cannot be obtained by using dry ice could be generated additionally. It is the main cause to bring more mosquitoes. The trap is consisted of the acidic and CO2-baited suction system. CO2 was so powerful mosquito attractant gas, and the color and shape of a suction trap was also very important factors for improving the mosquito capturing efficiency. The trap burned naphtha in a rate of 1.3g/hr~3.0g/hr (CO2:50ml/min-110ml/min) and the efficiency of the trap was higher at the burning rate with the high number of female mosquitoes. The second mosquito trap called DMS (Digital Mosquito Monitoring System) is developed for reporting the number of captured mosquito automatically every day. This automatic reporting device called DMS uses CO2 gas as a mosquito attractant and it has a IR array sensor for counting mosquito. We established a sensor network with several DMSs and one server. The server collected the data of each DMS through Internet or CDMA RF communication system. This data were analyzed in the GIS pest prevention information system and were sometimes used as a reference for the next pest control activities. The DMS systems emit CO2 about 300cc/min. CO2 was very effective for attracting mosquito. DMS systems were very effective to count the number of mosquitoes at the certain areas. By using two kinds of mosquito traps together, we could determine the mosquito population size increase and decrease at certain areas
