近年来,“非典”、禽流感、埃博拉出血热等疫情不断地提示公众和社会要高度关注公共卫生工作.历史的经验是“先其未然,谓之防;发而止之,谓之控;行而责之,谓之戒;防为上,控次之,戒为下”.公共卫生维系着人群健康和生产力发展,深刻影响着经济和社会发展[1].

Objective To provide scientific evidence for studying biological characteristic of cockroaches and control countermeasures by investigating the species distribution and inroads situation of cockroaches in civil aircraft.Methods In August 2015,the onsite investigations were done for 19 A320 and A321 aircrafts harbored at Sanya airport and Haikou airport for getting the cockroach density.The difference of cockroache density was compared by aircraft type,aircraft age and the 4 areas of the aircraft.Results The total invasion rate was 84.21％ on 19 aircrafts.Blauella germanica is the dominant specie.The invasion rates of cockroaches was not statistically significant neither by the comparison of aircraft type (x2 =1.362,P＞0.05) nor by the comparison of aircraft age (x2=0.281,P ＞ 0.05).But statistical significance on cockroaches density was found in the comparison of 4 areas of aircrafts (x2=14.629,P＜0.01).Conclusions The comprehensive countermeasures,including environmental,physical and chemical controls,should be adopted according to the aircraft structure,operation and safety requirements.
