目的：了解某城市营区内医学昆虫种类及消长情况，深入开展除害灭病工作，提高部队生活质量与环境质量。方法：１９９３ ～１９９７ 年对某市营区内蝇类、蚊类、蟑螂的种类及季节消长情况连续监测５ 年，并结合部队实际探讨提出防治对策。结果：营区内蝇类舍蝇占９４ ．３７ ％ ，密度高峰在６ 月中下旬。蚊类为淡色库蚊，密度高峰在７ 月中下旬及８ 月上旬。室内蟑螂全部为德国小蠊，密度高峰在２ 月和３ 月份。在蝇类、蚊类密度高峰前半月实行大面积喷洒杀虫剂可使当年高峰消失。营区内综合治理再配以有的放矢的化学防治，蝇类密度年下降率可达６０％ ～９０ ％ 。结论：城市营区内医学昆虫季节性消长有一定规律，应在适当时机有针对性地使用化学药物防治，并对营院环境采取综合治理，以降低医学昆虫密度，确保环境质量
OBJECTIVE: To understand the types and growth and decline of medical insects in a city camp, to carry out the work of eliminating pests and eliminate diseases, and to improve the quality of life and environmental quality of troops. Methods: From 1993 to 1997, the species and seasonal fluctuation of flies, mosquitoes and cockroaches in a certain urban area were continuously monitored for 5 years. Combining with the actual investigation of the troops, some countermeasures were put forward. Results: flies in the camp flies accounted for 94. 37%, the density peak in late June. Mosquitoes Culex pipiens pallens, density peak in late July and early August. Cockroaches in the room are all German cockroaches with peak densities in February and March. In the flies, mosquito density peak in the first half of the implementation of large-scale spraying pesticides can peak year vanished. Comprehensive management of the camp area together with targeted chemical control, the decline in the density of flies up to 60% to 90%. Conclusion: The seasonal fluctuation of medical insects in the urban area has some rules. Chemical drugs should be used and controlled in proper time and comprehensive treatment should be taken for the camp’s environment so as to reduce the density of medical insects and ensure the environmental quality
