目的调查研究昆明局管内旅客列车蟑螂优势种群及分布情况,对蟑螂带菌情况进行调查研究,为科学有效防治蟑螂提供依据。方法对昆明局旅客列车硬座、餐车、硬卧等共计936节列车车厢蟑螂密度现场调查,依据国家标准检验方法试虫(实验研究用虫)进行致病菌检测。结果 2010—2012年每个季度对抽样旅客列车车厢蟑螂密度监测,共检出4 314只,其中德国小蠊4 198只,占98%,最高密度为2.66只/辆,最低密度为0.72只/辆;从实验成虫中检出甲型副伤寒沙门菌、大肠杆菌、金黄色葡萄球菌、蜡样芽胞杆菌、志贺菌、霉菌等致病菌;对试虫蟑螂携带菌检测均检出致病菌。结论德国小蠊为昆明局旅客列车上的优势种群。
Objective To investigate the dominant population and distribution of cockroach in passenger trains under the control of Kunming Bureau of Civil Aviation and to investigate the bacteriological conditions of cockroaches in order to provide basis for scientific and effective control of cockroaches. Methods A total of 936 train cockroach density locomotives were surveyed in Kunming Railway Passenger Train with hard seat, dining car and hard sleeper. The pathogen was tested according to the national standard test method (experimental study with worms). Results A total of 4 314 cockroach densities were detected during each quarter of 2010-12 in the sampled passenger trains, of which 4 198 were German cockroaches (98%), the highest density was 2.66, the lowest density was 0.72, The pathogenic bacteria of Salmonella paratyphi A, Escherichia coli, Staphylococcus aureus, Bacillus cereus, Shigella, Shigella and so on were detected from the adult adults. bacteria. Conclusion German cockroach is the dominant population on the passenger train of Kunming Bureau.
