Abstract: Objective To make a thorough investigation on the ecological habits of mosquitoes and their hazards in a military maneuver field of Southeast China, providing some basic information for the control of the insects. Methods Mosquitoes were captured using CO₂ traps and insect nets, with identification, classification and statistical analysis done. The population composition and day and night activities of mosquitoes were investigated, with the mosquito biting index, reactions of soldiers to bites and the mosquito - borne diseases in the past five years involved. Results Twelve species belonging to 6 genus of mosquitoes were found in the investigation, with Culex tritaeniorhynchus (35.04% ), Cx. pipiens quinquefasciatus (25.91% ), Anopheles sinensis (18.54%), Armigeres subalbatus (10.17%) and Aedes albopictus (7.11%) being the dominant species. Mosquito activities peaked one hour before the sunrise and one or two hours after the sunset. The highest biting index could reach 14 mosquitoes/15 min one hour after the sunset. The main hazards from mosquitoes were blood-sucking and harassment, causing dermitis and in severe cases systemic allergic reactions. New comers who had more symptoms accounted for 66.74%, of whom 96.33% manifested phycological reactions such as restlessness and irritability. There had been no reports of malaria for the past five years, but occasional cases of encephalitis and dengue fever were seen, posing a potential threat to the stationed troops. Conclusion Integrated strategies based on the ecology should be taken to control and prevent mosquitoes for army troops who come to the area for military maneuvers.
