本文报告了方形黄鼠蚤松江亚种半数致死高温的测定及在1小时高温暴露中不同湿度对该蚤生存的影响。试验测得该蚤半数致死高温♀为40.81℃,♂为41.03℃;在41℃高温下暴露1小时,相对湿度82%—100%的条件对该蚤生存危害显著;61.5%—32%的湿度组则有利于存活。42℃时,各湿度下的死亡率均为100%。方形黄鼠蚤对高温的耐受界限与文献报告的印鼠客蚤相似。 This article reports the determination of the median lethal temperature of the Thalassiosira squamosum and the effects of different humidity on the survival of the flea during 1 hour high temperature exposure. The test found that the flea number half lethal high temperature ♀ 40.81 ℃, ♂ 41.03 ℃; 41 ℃ high temperature exposure for 1 hour, the relative humidity of 82% -100% of the conditions on the flea survival hazards are significant; 61.5% -32% humidity Group is conducive to survival. At 42 ° C, the mortality at all humidities was 100%. The tolerance of T. gonorrhoeae to high temperature was similar to that reported in the literature.
