Abstract:
Objective:To explore an effective prevention and control protocol of cockroach in aircraft based on integrated pest management (IPM) concept.Methods:① The current protocol of cockroach control in aircraft was improved based on the study of cockroach invasion in aircraft and the characteristics of flight operation and the IPM prevention and control protocol was proposed for deeply cleaning and killing cockroach at aircraft maintenance stage, the monitoring and controlling during flight operation and managing cockroach invasion in aircraft. ② The selected insecticide was tested for airworthiness and safety in accordance with AMS 1450A Aerospace material specification: disinsectant (insecticide), aircraft that issued by Society of Automotive Engineers. ③ Forty aircraft were randomly and averagely divided into 2 groups. One group was treated with the IPM cockroach control protocol as IPM group and the other group was treated with the current routine method as the control group. The density of cockroaches in 2 groups had been monitored for 12 months according to SN 1553 Codes of Surveillance for Vector-bonds in Entry-exit Aircraft. The infestation rate and infestation density index of the cockroaches in aircraft were compared between 2 groups to evaluate the control effect. Results:Field trials showed that the cockroach infestation rate of 2 groups was 80.0% and 75.0% respectively and the cockroach density index M ( P25, P75) was 8.0 (2.0,24.0) and 8.0 (2.0,23.0) respectively before treatment. There was no statistical difference between IPM group and control group ( P>0.05). By treatment, the cockroach infestation rate in IPM group was 1.2% and cockroach density index M ( P25, P75) was 0.00 (0.0, 0.1) while the cockroach infestation rate in control group was 16.6%, and the density index of cockroach M ( P25, P75) was 2.5 (0.0, 5.3). Statistical analysis showed that the density and infestation rate of cockroaches were significantly different between 2 groups ( P<0.01). The airworthiness tests showed that the selected insecticides fulfilled the requirements of AMS 1450A. Conclusions:The IPM control protocol can effectively control the infestation of cockroaches in aircraft and reduce the risk of vector transmission. The cockroach insecticides used in the protocol meet the airworthiness standards and can be safely used to prevent and control the infestation of cockroaches in aircraft.
