摘要: 目的 观察一款高温水蒸气设备杀灭室内德国小蠊效果,进而探寻高温水蒸气杀灭室内常见媒介昆虫的可能性。方法 在室温条件下,利用高温水蒸气从不同垂直高度喷射已固定的德国小蠊,喷射时间分别为1和2 s,观察灭虫效果与设备有效距离,并利用SPSS 16.0软件进行Pearson χ2检验。结果 高温水蒸气能够杀灭德国小蠊,当喷射时间为1 s时,喷射距离为0、5和10 cm组试虫死亡率为100%,喷射距离为11、12和13 cm组的试虫死亡率为30%,差异有统计学意义(χ2=96.923,P=0.000),高温水蒸气有效距离为10 cm;当喷射时间为2 s时,喷射距离为0、5、10、11和12 cm组试虫死亡率为99.3%,喷射距离为13、14和15 cm组的试虫死亡率为43.3%,差异有统计学意义(χ2=103.935,P=0.000),高温水蒸气有效距离为12 cm。结论 在有效喷射距离内,高温水蒸气能够100%杀灭德国小蠊,并推测该设备可用于杀灭跳蚤、臭虫等媒介昆虫。

Abstract: Objective To investigate the effect of a model of high-temperature steam equipment in killing indoor Blattella germanica and the possibility of high-temperature steam in killing common indoor insect vectors. Methods At room temperature, B. germanica were fastened and treated with high-temperature steam at different vertical heights, with an ejection time of 1 and 2 seconds, respectively. The insect-killing effect and the effective distance of the equipment were observed, and SPSS 16.0 software was used for the Pearson's chi-square test. Results High-temperature steam effectively killed B. germanica. When the ejection time was 1 second, there was a significant difference in death rate between the 0, 5, and 10 cm ejection distance groups (100%) and the 11, 12, and 13 cm ejection distance groups (30.0%)(χ2=96.923, P=0.000), and the effective distance of high-temperature steam was 10 cm; when the ejection time was 2 seconds, there was also a significant difference in death rate between the 0, 5, 10, 11, and 12 cm ejection distance groups (99.3%) and the 13, 14, and 15 cm ejection distance groups (43.3%)(χ2=103.935, P=0.000), and the effective distance of high-temperature steam was 12 cm. Conclusion Within the effective ejection distance, 100% of B. germanica can be killed by high- temperature steam, and the equipment may be used to kill insect vectors including fleas and bedbugs.
