目的调查中国驻南苏丹维和部队蟑螂危害状况和防治效果。方法用药激法调查蟑螂密度,采用物理和化学综合防治方法进行灭蟑螂处理。用蟑螂侵害率和密度下降率评价灭蟑效果。结果德国小蠊为绝对优势种,蟑螂侵害率防治前为72.48%,防治后12周侵害率下降为14.34%(37/258);厨房、餐厅蟑螂密度显著高于宿舍及其它场所(P<0.05);采取综合措施后,蟑螂密度显著下降,在12周监测时下降率达91.50%~100.00%,防治前后差异有统计学意义(P<0.05)。结论中国驻苏丹维和部队蟑螂侵害严重,采用物理和化学综合防治方法杀灭蟑螂效果显著。
Objective To investigate the status of the cockroach in Chinese peacekeeping troops in South Sudan and the control effect. Methods Investigate the density of cockroaches by using the method of stimulating drugs, and take the methods of integrated physical and chemical control to deal with cockroaches. The cockroach infestation rate and density declining rate were used to evaluate the cockroach killing effect. The results showed that Blattella germanica was the dominant species with the rate of cockroach infiltration being 72.48% before prevention and 14.34% (37/258) after 12 weeks of prevention and control. The density of cockroach in kitchen and restaurant was significantly higher than that in dormitory and other places (P <0.05 ). After taking the integrated measures, the density of cockroaches decreased significantly. The rate of decrease was 91.50% -100.00% at 12 weeks monitoring. The difference was statistically significant before and after the control (P <0.05). Conclusion The cockroaches of the Chinese peacekeepers in Sudan are seriously attacked and the killing effect of cockroaches by physical and chemical integrated control methods is remarkable.
