蚤 蚤目昆虫。恒温动物的体外寄生虫。善跳，俗称跳蚤。全世界约有2300种,中国已知近500种。随种类不同分布各异,致痒蚤（人蚤）几乎遍及全世界,中国除有致痒蚤外，南方各省也多见印鼠客蚤。某些种类叮人、吸血，并能传播鼠疫、斑疹伤寒（地方性）等疾病；有些蚤能传播某些绦虫病。 形态和生活史 成虫体长2～3mm，身体左右扁平，黄褐色，体壁硬而光滑，生有许多尖端向后的鬃毛，可使蚤便于在寄主的毛间活动。口器为刺吸式，雌雄均吸血。无翅。后足特别发达，善跳，饥饿蚤可跳30～38cm高，12～23cm远。雌蚤腹内受精囊及雄蚤外生殖器的形态，可作为分类依据。发育过程为完全变态，生活史分卵、幼虫、蛹和成虫四个时期，完成发育约需1个月,但有的种类蛹期长达1年。雌蚤吸血后不久,产卵于寄主栖息的场所，如动物的巢穴,有时卵产于寄主身上,寄主活动时落在地面。幼虫蛆状，主要孳生于动物巢穴、禽畜厩舍及屋角、墙缝、床下、土炕等处的尘土中。以尘土中的有机物，尤以成虫粪便中未消化的血为食。幼虫蜕皮2次后吐丝结茧,形成茧蛹。蛹羽化需要外来刺激，如寄主动物骚扰、空气振动或温度上升等，这些条件均可导致成虫破茧而出。因此，当人进入久无人住而有蚤蛹存在的房间时，会被大量跳蚤侵袭。多数种类的蚤对寄主特异性小，可吸多种动物的血,如致痒蚤可吸130多种动物的血，每天需吸血数次,每次吸血约2～3分钟,并有边吸血边排粪便的习性，这些习性与传播疾病有密切关系。蚤的耐饥力很强，某些蚤能耐饥达10个月之久。蚤的寿命较长，一般可活1～2年。印鼠客蚤在适宜条件下，可携带有毒力的鼠疫杆菌达1～1.5个月。鼠死后蚤即离开死鼠，这有助于疾病的传播。 蚤对人体的为害 主要是叮刺、骚扰和传播疾病。被叮咬部位常感奇痒，影响休息。某些人，尤其是儿童被叮咬后可出现丘疹、风团等。穿皮潜蚤的雌蚤寄生于人体皮内，引起潜蚤病，局部剧烈痛痒。蚤主要传播鼠疫和地方性斑疹伤寒（鼠型斑疹伤寒）以及某些绦虫病。鼠疫杆菌在蚤吸血时传播,鼠疫杆菌在蚤的前胃繁殖,阻塞前胃，蚤再吸血时新鲜血液难以吸入胃中，往往倒流，将蚤胃中鼠疫杆菌带入寄主体内。地方性斑疹伤寒的病原立克次氏体在蚤胃壁上皮细胞内繁殖,随蚤粪排出,污染皮肤伤口从而进入人体。 防制 主要是消灭孳生地、灭鼠，用药物杀灭幼虫及成虫等。堵鼠洞，清除室内尘土，保持地面、墙角光洁，可清除蚤的繁殖和生存场所。用2％杀螟松或5％硫磷粉剂喷洒地面可兼灭鼠和蚤。杀灭狗、猫等身体上的蚤宜用 1％除虫菊粉、5％马拉硫磷、1％残杀威等粉剂，以纱布包粉逆毛擦入或以 0.5％碘硫磷、0.25％马拉硫磷、0.0025溴氰菊酯等水溶液浸泡全身作药浴。
