云南省1976～1986年按蚊嗜血习性调查研究

目的 :了解云南省按蚊种类及嗜血习性 ,判断传疟媒介 ,为制定疟疾防治措施提供科学依据。方法 :用环状沉淀试验法 (沉淀法 )及对流免疫电泳法 (电泳法 ) ,以自制兔抗人、牛、猪 3种血清 ,对人、牛房采集的按蚊胃血滤纸标本进行鉴定。结果 :人房采集的 14种按蚊中 ,嗜人按蚊及昆明按蚊的人血指数最高 ,分别为 93 .18%及 88.96% ;中华按蚊及微小按蚊次之 ,分别为 3 7.92 %及 11.3 7% ,吉甫按蚊及八代按蚊人血指数虽较高 ,但种群数量太少 ,不足为判断依据。牛房采集的 18种按蚊均以吸牛血为主。结论 :根据人房采集的 4种按蚊与人类关系的密切程度及云南媒介按蚊睡腺解剖的报道 ,证实它们为云南省主要传疟媒介。

Studying on Blood Meal Habits of Anopheles in Yunnan During 1976~1986

Purpose: To study anopheles species and their blood meals in Yunnan, to determine malaria vectors and provide measures for malaria control. Methods: Using three antiserums e.g. anti man, anti cattle and anti pig to identificate blood meals of anopheles, which collected from human room and cattle corral by the precipitin ring test and convective immunoelectrophoresis methods. Results: Human blood indexes of An. anthropophagus and An. kunmingsis are highest among 1 anopheles species in human room, respectly 93.18% and 88.96%, those of An. sinensis and An. minimus are 37.92% and 11.37%, those of An. jeyporiensis and An. yatsushiroensis are higher, but their populations are too small to determine as malaria vectors; 18 anopheles species collecting from cattle corrals are mainly breeded on cattle. Conclusion: According to the relationships of 4 anopheles species with human being and original reports on dissecting for their saliva glands, we can determine that they are main malaria vectors in Yunnan province.
