舰船蟑螂化学防治策略研究

Cockroaches chemical control strategies in ship

目的探讨舰船蟑螂化学防治策略。方法分析舰船上常用化学防治手段的优劣,通过试验研究,评判几种化学防治方法的不同组合对于舰船蟑螂的长期控制效果。结果烟雾法和毒饵较为适合舰船蟑螂的控制,它们的组合可显著控制蟑螂密度及其反弹速度,处置措施合理,可维持5个月的低密度水平。结论舰船蟑螂危害的有效控制必须建立定期的密度监测机制,根据不同危害等级采取相应的化学防治手段,科学合理用药,以实现舰船蟑螂防控的预见性、有效性和可持续性。

Objective To approach the chemical control strategies for cockroaches in ship. Methods The chemical control strategies frequently used at present were taken into consideration with respects to their merits and demerits,and the effects of various combination of chemical control methods on long-term cockroach control were judged through field experiments. Results Smoke fog and poison bait were ideal for control of cockroaches in ship.Furthermore,the cockroach densities decreased strikingly and their relapses were not observed under the combination of these two treatments,which maintained for 5 months at low densities with rational treatments. Conclusion Density monitoring is advised to be established to control cockroaches effectively in ship,and according to various hazard scales,the corresponding chemical control strategies,in addition to rational administration,are adopted for effectively persistent control of cockroaches in ship in advance.
