目的分析探讨民航飞机蜚蠊侵害特征及风险因素,为科学防控飞机蜚蠊危害提供依据。方法2015年6月至11月,按分层随机抽样原则,对3家航空公司89架飞机进行蜚蠊密度监测、种群鉴定及体外病原菌分离鉴定。运用logistic回归模型分析飞机蜚蠊侵害的影响因素。结果民航飞机蜚蠊侵害率为29.7%~84.2%,蜚蠊密度M(IQR)值为0~0.73只/屋(0~1.00只/屋),3家航空公司飞机蜚蠊侵害率及密度差异有统计学意义(P<0.05)。飞机蜚蠊的优势种群为德国小蠊,蜚蠊体外细菌阳性检出率为100%(233/233),共分离出9个病原菌种属。logistic回归分析显示,飞机蜚蠊侵害的危险因素为飞机灭蟑频率大于180 d(OR=15.09,P=0.000),座舱清洁卫生差(OR=12.61,P=0.000),无定期飞机蜚蠊监测(OR=7.50,P=0.001),机供品及航空货运仓库蜚蠊防控差(OR=12.16,P=0.000)。结论民航飞机蜚蠊侵害率高,各航空公司飞机蜚蠊控制效果差异悬殊,是否实施定期蜚蠊监测、预防性杀灭措施、客舱清洁卫生以及机场蜚蠊防控水平是影响飞机蜚蠊侵害的关键因素。飞机蜚蠊防治对策应遵循有害生物综合防控(integrated pest management,IPM)策略,采取持之以恒综合治理措施。
Objective To analyze and discuss the characteristics and risk factors of cockroaches of civil aviation aircraft and provide basis for scientific prevention and control of the cockroach of aircraft. Methods From June to November 2015, 89 aircraft from 3 airlines were monitored for cockroach density, population identification and isolation and identification of pathogens in vitro according to the principle of stratified random sampling. Using Logistic Regression Model to Analyze Influential Factors of Aircraft Cockroach Infringement. Results The cockroach attack rate of civil aviation aircraft was 29.7% -84.2%, the cockroach density M (IQR) was 0 ~ 0.73 / house (0-1.00 house / house), the cockroach attack rate and density of three airlines were different There was statistical significance (P <0.05). The dominant species of cockroach was Blattella germanica, and the positive rate of bacterium in cockroach was 100% (233/233). Nine species of pathogens were isolated. Logistic regression analysis showed that the risk factors of aircraft cockroaches were plane cockroaches frequency> 180 d (OR = 15.09, P = 0.000), bad cockpit hygiene (OR = 12.61, P = 0.000) (OR = 7.50, P = 0.001), cockroach control and cargo warehousing (OR = 12.16, P = 0.000). Conclusions The cockroaches affected by civil aircraft are high, and the control effect of cockroaches on airlines is very different. Whether cockroach monitoring, preventive measures, cabin cleaning and airport cockroach control are affected by cockroaches. The key factor. The cockroach control strategy for aircraft should follow the integrated pest management (IPM) strategy and take consistent management measures.
