摘　　要：目的控制旅客列车德国小蠊的侵害。方法灭蟑毒饵粉剂、杀蟑胶饵多种方法相结合。结果采用药物直接喷洒,再广泛使用灭蟑毒饵粉剂,同时辅以胶饵,7月蜚蠊侵害率比最高峰6月下降了64.79%,8月下降了90.35%,8月后侵害率控制在2.0%以下。7月与6月相比蜚蠊重度侵害车厢减少了69.76%,中度车厢减少了66.86%,轻度车厢减少了53.85%。8月与6月相比重度车厢减少了98.79%,中度车厢减少了86.98%,轻度车厢减少了73.63%。9月以后未再发现重度危害车厢,中度危害车厢也比6月减少了95.86%以上,轻度危害车厢比6月减少了78.02%以上。结论化学防治仍是目前灭蜚蠊的一项重要手段,采用多种药物互补,同时加强环境治理和服务质量的管理,能很好地控制旅客列车德国小蠊的侵害。Objective To control the invasion of Blattella germanica on passenger trains. Methods Several measures were corporately used in this study, including spray, poisonous powder and gel bait. Results Compared to June, the cockroach density decreased 64.79 % in July and 90.35 % in August. The invasion rate was under 2.0 % since August. In addition, in July, the invasion of cockroach decreased 69.76% in the serious invasion carriages, 66.86% in the moderate invasion carriages and 53.85% in the slight invasion carriages, respectively. In August, it decreased 98.79% in the serious invasion carriages, 86.98% in the moderate invasion carriages and 73.63 % in the slight invasion carriages, respectively. The serious invasion carriage had never founded in September, and it decreased 95.86 % in the moderate invasion carriages and 78.02 % in the slight invasion carriages. Conclusion At present, chemical control is still a key measure to control cockroach, and several chemicals combination measure can effectively control the invasion of the cockroach, synchronously strengthening the environment repairs and service quality management.
