牛(牦牛)内寄生虫感染情况的调查及亚东璃眼蜱生活习性的观察
Observations on the Endoparasites Infection in Cattle / Yaks and Living-habits of Hyalomma asiaticum kozlovi in Hejing County
摘要
Abstract
[ Objective ] This study was designed to investigate the biological characteristics of the dominant species of hyalomma and the species, infection rate and harm infected of endoparasites in Cattle or Yaks in epidemic areas of Xinjiang. [Method]The living - habits of the dominant species of hyalomma and the infection with endoparasites was investigated by tick -feeding experiment and fecal examination. [Result] The results obtained from the identification and experimental observation of a cycle tick - feeding showed that the dominant species of hyalomma was H. asiaticum kozlovi in epidemic areas. And its life style has changed. Seventy four percent( 88/119) larvae which had changed from three - host tick into two - host - tick, exuviated into nymphal tick to hematophagia instead of ablating after engorgement. The exuviation period and exuviation rate of nymphae were 23 -33 d(26 d averaged)and 100% , respectively. On the other hand, 26% (31/119) larvae showed 3 -9 d(5 d averaged)blood-sucking period, 7 -12 d(10 d averaged)exuviation period and 83.9% (26/31) exuviation rate after engorgement. The nymph was found to have 6-8 d(7 d averaged) blood -sucking period, 25 -33 d(29 d averaged) exuviation period and 88. 5% (23/26) exuviation rate. Adult ticks showed 4 d blood - sucking period, 26 d pre - spawningpe period, 20 d spawning period and lid eggsincubation period. The pathogen results revealed that the infection rate of parasites in Yaks at Baluntai and Bayinbuluke Alpine Grassland were 69. 05% (29/42) and 85. 14% (63/74), respectively. The total infection rate was 79.31 % ( 92/116) and most cases were mixed infection. The infection rate of Nematodes was higher than that of others. [ Conclusion ] H. asiaticum kozlovi was the dominant species of ticks in Xinjiang and maybe related prevention measures can be taken according to its biological characteristics.关键词
