用实验室饲养的方叶栉眼蚤，在室温环境下叮咬６位自愿者前臂的观察显示，在饥饿后第１和第２大的吸血率仅为１．１％（１／９０），表明该蚤对人的嗜血能力较差，基本不叮吸人血。在温度１８±１℃，相对湿度８０±５％的条件下，饥饿幼龄蚤寿命为７．８５（２～１３）ｄ，成龄蚤６．９５（６～８）ｄ；吸血蚤寿命４８．１８（６～８４）ｄ。新羽化蚤体重０．２６８±０．０６６ｍｇ，吸血后成蚤体重０．３８３±０．０５８ｍｇ。吸血鼠雌蚤为０．１１５１ｍｇ（０．０００１０７ｍｌ），雄蚤为０．１２３ｍｇ（０．０００１１４ｍｌ）。 Observations of forearm bites in six volunteers at room temperature by laboratory-held square leaf fleas showed that the first and second largest rates of aspiration were only 1.1% (1/90) after starvation, indicating The flea bloodthirsty people on the poor, the basic does not bite human blood. Under the conditions of temperature 18 ± 1 ℃ and relative humidity 80 ± 5%, the lifespan of starved young flea was 7.85 (ranged from 2 to 13) days, and that of adult flea was 6.95 (ranged from 6 to 8) .18 (6 ~ 84) d. The new feather flea weighing 0.268 ± 0.066mg, after sucking blood flea weight 0.383 ± 0.058mg. Feathery females were 0.1151 mg (0.000107 ml) and males 0.123 mg (0.000114 ml).
